Sparco QRT-R - anyone haz?
 

In my search for a seat that would allow me under the bar in my miata, I found this contender: SPARCO QRT-R . This thing seems to tick all the right boxes: made to fit larger / taller drivers, made for small cockpits, and FIA approved.

Does anyone have one in their garage / car (same thing imho), and can share first person experience with this guy?

Thanks,
JT

Sparco hasn't updated the seat sizing chart for 2018 it appears but i was able to find the dimensions on the sparco official website. It looks to be similar in sizing to the Sprint L so dimensions should be fine. I would be more concerned how you fit yourself in the seat and if its comfortable. Do you know of a local sparco retailer in the bay?

Looks like a nice seat, but I don't see anything that makes it especially tall-guy friendly. Have you considered a Tillett B5 or B6-XL?

​​​​​​Thanks man, I'll see if there is a sparco dealership around me. I couldnt find dimensions of the seat before either.

I have not, just starting to explore options: Kirkey / ultrashield, cheaper fiberglass options before going the baller carbon carbon.
bigger tillets maybe an option at some point, I'll try to find threads of those seats on here.

I ordered it, couldn't find any reviews on it. I took the chance. Eta 2 weeks

You are a gentleman and a scholar.

Sparco QRT.
Light!

Has anyone tried this seat yet? It looks like I may be able to fit. There aren't any sparco dealers anywhere close to me.

Ive got a pretty wide build which usually means most seats don't work well. Looking for a seat I can street drive but is primarily for track.

Have you received your seat? Any impressions you can share?

Thanks,
JT

I recieved the seat yesterday. It fits me perfect, one of the best seats I've sat in. Now here is the problem, it doesn't fit the pci mount I have and the trans tunnel needs to be massaged. I'm trying to make it fit my pci mount but the mount isn't tall enough in the rear to catch. Any suggestions on mounts?

The trans tunnel always needs to be massaged to fit just about any seat bracket, including the PCI mount. There's at least one person who has installed this seat in an NC with a PCI seat bracket, so it sounds like you may not have things lined up right.

https://cimg1.ibsrv.net/gimg/www.mia...069d757879.pngJpreston here makes some good mounts.Thanks for the info! How tall are you btw? I'm 34w 6ft 210 all torso. I am planning to drop the seat pan plus a seat like this..

Yes I knew the tunnel has to be massaged to fit pci mount. Besides that, I'll take a picture later on what I mean that rear wont catch the mount. The seat bottom isn't flat, its lower on the butt area and sits on the mount.

Ohhh you have the one-piece version. We don't sell that version because it is really limited in what seats it works with, I practically forgot it existed. Sorry to say it but that doesn't look like it's going to work. You want the adjustable version: https://www.good-win-racing.com/Mazd...t/61-1914.html

Seat positioning has way more flexibility and most importantly, as you can see in the pics the rear holes are a lot higher.

An additional note - when we got the first set of the PCI brackets for eval one of our notes to PCI was that cross bar between the two rear holes limited seat placement, so PCI redesigned the brackets with that cross bar removed. All of the NA/NB PCI brackets we sell do not have that cross bar there so the rear bottom point of the seat, which is typically the lowest point, can practically touch the floor (pic on our site is provided by PCI, doesn't show the latest version sans cross bar).

I'm going to order this mount from Goodwin right now. Since you say the picture is different and it doesn't have the crossbar. I wasted money on this mount but maybe I'll be able to sell it.

I got my new mount. Looks like it will work.

:bigtu: Let us know how it works.

Looks good!

Just got a note from one of our Sparco distributors:

"The QRT-V is no longer being brought into the US by Sparco."

So it's just the QRT-R now.

what's the difference?

QRT-R vs QRT-V

Looks like larger harness holes on the R.

Deposit down for a QRT-R, will post up details once its in my grubby lil hands.

would love to hear how well it fits in the miata. I made a mistake with a pro-2000. Fit horribly.

QRT V was the 'euro' model. Only brought over when QRT R quantity was late/short.
V also has higher side mount hole locations and needs the taller brackets. Harness slot shape different as mentioned above.

https://cimg2.ibsrv.net/gimg/www.mia...d591facf42.jpgI fit in my duece roll bar finally and the seat bolted down. This seat fits perfectly. Anything slightly larger would never fit.

https://cimg8.ibsrv.net/gimg/www.mia...d837d8496e.jpgThe newer pci mount is great, but there is still about an inch or 2 between seat bottom and floor. Would need custom longer bracket, cut out the rear mounting humps and massage the back rest. I still want to be able to put stock seat back in. Im happy with the height since im only 6 foot.

are you lower than the stock seat?

Yes way lower than stock seat. I'll put stock seat in just for a picture comparison in future. I didnt bolt in the roll bar yet.

looks like it fits but just barely. How's the comfort?

Looks tight on the B-pillar, will be interested to see it when the trim is back on. But the door closes which is the usual issue so that's great!
Keen to see how much lower it is than stock and hear your thoughts on comfort over an hours drive.

Wont be driven for a while. How much comfort can you expect out of a miata with competition seat. The trim on the pillars is thin, should not effect it much. Seat barely fits, I took the chance to try this seat out blind and I'm happy with it. I took most of the seat apart to avoid damage, the quality isn't the best, it's what 800-1000 seats feel like. I didnt expect 6000 porsche gt2 seat quality. It's very lightweight

How the hell does this seat fit but not the Sparco Revs i just tried to make work on the same mounts? The seats physically fit great, but i cannot pass a broomstick test sitting in them, and i'm only 5'8".

We have no photo of 6ft OP sitting in his seat/mount and passing a broomstick.
PCI mount was impossible to fit in my car low enough for my standards. It sits above the humps, leaving an air gap from mount to floor and doesn't allow most seats to bottom out in the mount, leaving another air gap from seat to mount. I passed it on and cut my rear humps out.

Right. They work great with my Sprints, but i also sat in a car last week that had the 1 piece PCI mounts on Sprints with the rear humps out, and it was looooowwwwwwww.

If i could verify that the 1 piece PCI mounts fit on Revs, i'd probably give that a shot. I dislike the adjustment design of the 2 piece mounts from a seat height perspective because the adjustment bolts/nuts also take up available room for low mounting. It only works with the Sprints because sling bottom.

It should be obvious that the relevant dimension here is trunk length, NOT height. I know tall drivers who have no problem with seating position, I know short(er) drivers who do. Because we vary in how we are built, over and above height alone.

It would be nice if, when stating fit in a setup, if the driver could include both full height and something like height sitting flat-backed against a wall. That would give a fairly accurate guesstimate to passing the broomstick test or not.

I think it's the seat, not any weird way that i'm built. It's not like i have a 22" inseam. :magna:

Oof, and here I thought I was bad at 5'11 and a 29" inseam...

I mean i DON'T have that lol. I have a 30" inseam, which doesn't leave much room for my torso to be freakish.

An update!

In my quest of trying to fit my oversized torso into a hair dresser's car, I picked up a Sparco QRT and a lowered seat pan for my miata.

My buddy T of All Automotive (Twibs415 to us trubo kitteh folk) offered to help me in my cause.
Seat pan cut, welded, and painted, T was able to fit my Sparco QRT with Sparco rails, was able to get the QRT and me under the roll bar. If you are in the SF bay area, definitely worth hitting up T for anything miata / car related work.

A few notes:

• Sparco QRT seat with the lowered pan barely fits. The wings hit the door with LRB door panels and requires a slightly stronger slam to get the door closed. Steel seat rails are the only option for seat mounting, no room for aluminum I think.
• The seat has a fairly flat bottom and little to no thigh support. Maxing out the top holes for the front and lowest holes on the rear offer little tilt and thigh support with the existing seat rails. I'm looking at other rail options to get some tilt (OMP perhaps?)
• Being a bigger dude, 225, 6ft with 30inch inseam, the seat is pretty comfortable, but without more tilt / layback + a lil more lumbar, it does get a lil painful after an hour or so.
• Stock cat fits (just barely) with the dropped floor pan
• Stock NB2 bracing needs to be modified or removed entirely (I just tossed it)

I've been looking at this seat as well and was wondering if you've received/installed it and could offer any thoughts on fit.

I have them installed in my MSM. I ended up getting the batch of the QRT-V got them in with the RTheory seat brace and Sparco side mounts. Trans tunnel definitely needed a good banging on both sides. The seat does hit oem the door cards but eventually it molds to the shape of the seat. I have LRB panels coming to see if its better. The seats do not fit with the hard dog door bars. Ended up getting rid of them. The seats are very comfortable and very light !

Update part 2!

Turns out that Sparco had the seat holes in their QRT seats higher than their other seats, so had specific mounts made for them (go figure I found this out after installing the seat), to allow a better layback angle than you would have with the stock Sparco mounts.

In need of more layback, I bit the bullet and bought the mounts. As you see below, the standard mount (front) is about 2 inches shorter than the QRT mount (rear).
https://cimg9.ibsrv.net/gimg/www.mia...2a4aca6239.jpg

A few other differences to note: the angle of the mount is slightly different, making the seat's footprint with the mounts about .5 inch wider overall, and the mount itself is shorter in such a way that the bolt holes of the new mount don't match up to the old mount. Good news is that the layback is awesome, and the angle reminds me a little bit of sitting in an Elise seat mounted in a miata = a lot more comfortable than the standard mounts.

stupid bolt holes

Bad news: As I mentioned, the new mounts sit .5 inch wider, thus making it .5 inch too wide to actually fit in the car. So what to do? Cut the old mounts that actually did fit and make them higher!

"Custom mounts" attached to seat and seat is back in the car. I had to move seat forward a bolt hole, but the difference in seating position was more than I expected. The seat in this new position seems a lot more of how this seat was designed IMHO and a lot more comfortable to me.

Seat angle makes top of seat even lower than before
https://cimg1.ibsrv.net/gimg/www.mia...d99c8bc032.jpg
Black mark on door panel was where the seat was rubbing against the door with the unmodified mounts

TLDR:
Sparco makes mounts for their QRT seats that offer a better layback and thigh support, but makes the seat footprint too wide to fit in my lowered floorpan miata. I modified the original mounts using the new mounts as a guide, and reinstalled seat to find myself not only more comfortable, but even lower than before.

Here is a great option for mounting the QRT-R in an NA chassis.

At 22" shoulder bolster width I knew this would fit in a NA, but would probably touch the door panel. I went for it and ordered one. I looked at several of the available seat mounting options and this thread trying to figure out what would work. I initially thought the Jerfspeed was going to work. After talking with Jeff it was apparent that the rear portion of his mounts were not tall enough to reach the rear mount on the seat. I don't know why Sparco decided this seat needed higher mounting points.

I don't remember how I came across it, but I found a thread on facebook where someone mentioned Bell Raceworks mounts. From the looks of them I thought they would work, but wasn't sure. I took a chance and ordered up two sets. Turns out they do fit, but only using the top slot. In the top slot the rear of the seat is about 1/4" from the floor, a bit more in the car since the front is raised up on the front seat mount beam/hump. The Bell mounts are designed to mount by removing the rear seat hump and bolting the rear directly to the floor. I had already removed the drivers side seat humps and modified my stock seat to sit lower in the car, so no problem for me.

Here is the link to Bell Raceworks and the picture of the mounts on their site. https://bellraceworks.bigcartel.com/...-seat-brackets

Installation was pretty straightforward as expected. Front two stock mounts are used. Drill holes for the rear two seat mounts and use bolts and backing plates. I did have to massage the transmission tunnel with a hammer and cut the outside edge of the seat mount so it would lay flat on the mount.

The seat sits much lower than stock and with the seat pushed as far towards the transmission tunnel as possible the shoulder bolster does touch the door panel top. The door still closed, but was touching the seat and caused some squeaking while driving. I decided to cut a notch out of the top of the panel so there would be no interference, which worked well. The seat does not touch now when closed. The next time I have my hard top off I'll get a broomstick test pic to show the height.

Seat installed.

I am an average height around 5' 10". The seat is slid as far forward on the mounts as it will go. I can drive it great like this, but I wish there was a couple inches more of forward adjustment. I may take the second set of mounts to a fabricator and have them modified to give a couple more inches of adjustment. Or, I may just get used to it like this and leave it as is. If you are tall these mounts would be great for you! There is probably enough room behind the seat to slide the seat all the way back on the mounts. .

I really like this seat! Fits me great and looks great! I'll be getting a second one for the passenger side soon.

Reviving thread to maintain existing conversation and add to knowledge.

Considering QRT-R for my NB, I'm 5'11" (6ft if any women ask me) and 240 lbs, I think the QRT-R should fit me just fine.

Interested in using the QRT-R, would this be possible with a factory floorpan? The Bell seat brackets look like a good possibility, any idea if they'll work on the passenger side? I see they require drilling a additional holes in the rear, is that area strong enough to withstand a crash?

Yes, you can install a QRT-R on a factory floor pan. I am 5'10" and my helmet is a couple inches under my roll bar.

Yes, the Bell brackets work on the passenger side as well. I now have two QRT's in my car.

https://cimg7.ibsrv.net/gimg/www.mia...13073f4fc.jpeg

The floor pan itself is not strong enough, so you will need to use a backing plate under the rear seat mounting points. This is what I used.

I hope that helps! Let me know if you have any other questions.

Awesome, thanks! What's your waist size, how well do you fit in that seat? I'm a 38 waist so some seats are tight on me.

I am a 34. I know someone with a 36 who tried out my seats and said they were still comfortable. 38 might be a little tight, but hard to know without trying them out. There is a Sparco that fits a larger waist size, but I can't remember right off which one it is.

Yeah, I need to get out there and try something out
