Looking for NA seat options.
I've got an NA that has a pretty bad drivers seat. I'm looking for one that will fit and either use the stock slider or have an aftermarket one. I need one comfortable enough to daily and have provisions for a 5-Point. Thanks for the help!
Momo Start/Sparco Sprint
Fab up some rails that mount to the factory location, use a sledge to beat on the transmission tunnel, and realize that mounting race seats is one of the most miserable things you can do on a car.

Elise seats are the only thing that I know that fits both of these and fits in the car. If you're DDing and can't find Elise seats, you're gonna want some new stock ones. Maybe cut a hole in the seat for a 5 point.
Any of the kirkey's fit up to at least the fat person 17" wide ones, the obese person 21" seats might not fit. The average size person 15.5" ones drop in not problem, just use some steel to fab up a mount adapter between the seat and the rail. This can be done with hand tools.
Elise seats do not have provisions for anti-sub belts as far as I know.
The Sparco Speed2 should fit with the Wedge Engineering/Sparco bases and sliders.

I have Sparco Revs. The driver side is a Wedge/Sparco base + Sparco slider. The passenger is on a Nagisa Auto super low rail + slider combo. I did have to hammer the tunnel a bit to on the passenger side, as I recall, to get a more full range of motion. It's under the carpet, so no big deal.

I do DD the 3-series. Getting in and out of the Sparcos is more cumbersome than a stock seat or an Elise seat due to the sides, but not overly arduous. Then again, I am efficiently packaged (~5'7", 160 lbs) and fairly agile. There is definitely a technique to it, and I have a quick release steering wheel which does help.
The seats are not the most comfortable things in the world, but I've driven them hundreds of miles at a time (from central FL to Roebling and back).
The focus of my car is probably 80% track and 20% street. If those were flipped, I'd consider spending more money on an Elise-style seat (like the Corbeau LE).

Or the Cobra Racer 7

I'd say no to DD'ing a Sparco Sprint V... I was in the same situation, and now have a stock seat on sliders and the sparco for track days.
Entry and exit sucks with the race seat, and using a 5pt to dd sucks. I just swap back and forth. Also making your own mounts is hard. buy some.

The good side with most kirkeys is that you can use the stock belts and if you fit the seat properly they're super comfortable. Entry and exit is a pain, and the vinyl cover on the cheaper kirkeys sucks because of back sweat.
I've thought about cutting a hole in the bottom of stock seats for a sub belt. I could then continue using stock belts to DD and 5-point at the track/when I want ricer points.
How horribly unsafe an idea is that?

I could use the stock seatbelts with my Sparco Revs and will probably look to try that. The problem for me is not the seat but the Harddog rollbar which places the seatbelts at an angle that slows standard retraction, even with the little adaptor brackets.
Harnesses + fixed-back seat = the suck for a daily driver.

I end up with the Marrad seats from Goodwin. They are a bit pricey, but include the base and slider, it works out the same as a fiberglass Sparco with base and slider. They bolt in with no welding, although it takes me 30 minutes to get the passenger seat back in.
With the cushions in they are daily drivable, I did two 9 hour trips each way in them. Without the cushions they'll get your head under the bar. They have the proper holes for a 5-Point. I use some of the special seat foam from Pegasus Racing for track days.
They're a compromise seat, not the best daily seat, not the best racing seat, but will work for a car that does both.
