I am interested, but confused. Are you offering the black one (8 inch, 2.5 diameter) and the silver QA1 or the black one and some other non-pictured spring?

The part # on the QA1 says it is a 2.5" x 7" x 400lb (which is 7k).

A 6k spring is 336lbs. Is 6 inches a little short on that for the amount of travel that would be expected? I think I read something about that once. I'm obviously a rookie so I need some explanin' so I don't screw up.

i didnt offer the silver ones. obviously i was offering the black ones since I showed a second picture of them with the measurements :)

the 6K ones are the stock rear ones of the teins, the 7K are Stance springs.

That's what I thought you meant but I've learned the hard way around here to ask the obvious. :)

PM me prices, please sir.

make me an offer i can refuse. both sets are collect dust.

Dude, you are way over thinking this stuff. Have you read the ebay coilover thread on miata.net. Quit talking about jacking down, revalves, etc. Your a rookie and shouldn't be concerned about such things. Order some ebay coilovers for a "miata" and profit. The rates are generally 450/350 and we can even that out with the sway selection. It is the super budget way to rock out at the track. I've ran ebay collars and springs in different combinations on 4-5 miata's over the last 4 years. Here is what I want you to do...

This entire setup will cost about $400 including mount balance/track alignment with big camber and drop big time off your laps. Please don't be a budget racer and a parts snob, you will never get fast. Throw the budget setup on there and be the budget racer that you are. There is nothing to guess about, its been done 1000 times. Not trying to be a dick, but someone had to slap you.

jacking down only happens on shocks with tons of rebound and soft springs...

Question about the Honda bumpstops: I bought a set of the KYB bumpstops because I could not find the Honda part number searching here or on M.net. Any problem using those vs. the Honda jobs? I haven't actually bothered to put them on yet, so I could return them or resell them if Honda does it better.

you are the fail at search: http://www.hondapartsnow.com/genuine...2-SR0-003.html


BTW. I was back in a miata with Koni Sports and GC 550/300. It wasnt THAT bad; I'm just a baby. But it was noticable over my tiens.

Just make sure those are the foam stops that guys are running. I had that part number from the site Brain posted saved in my favorites but that research was months ago and I've forgot all the details.

Fuck me sideways, how did I not find that before? I did find it on M.net, but the part number is just slightly different: 51722-SR0-003, which matches what Brain linked.

Gonna get the cheese. :bowrofl:

Parts snob? Moi? No way! Everything I have is secondhand crap but my 949 endlinks.

I don't go on miata.net because it makes my head hurt but I will study this over there now. I studied what people have in their build threads here but people are notoriously vague about some items that "everybody knows about."

I have NB tophats, FM swaybar, 949 endlinks, stinkycheez is sending me some coilover adjusters, and I'm getting the 400lb springs from Brain. I have newish NB Bilsteins and some old Koni yellows to play with. I never heard anything about the honda bumpstops and I try to read everything I can over here. That must be a m.net nugget also. I do intend to use used track tires because I use used street tires already. More advice is welcome because that is the obvious reason I made this thread. So keep it coming. And thank you.

Like if I used Koni Yellows with my stock springs?

Buttplug? Do not want.

That curve was designed for stock springs to keep on the bumps and jack up the spring rates during tight corners.

Listen to jake's words of wisdom. I drove his POS "fancy pants" at Hallett last year. That car was a giant turd, but the suspension was the best part of the car. It was extremely balanced and didn't have issues with traction over the rough bumps on the track. It was perfectly controllable when the 10 minutes storm soaked the track and I was sliding around on race tires.

I don't think Steve needs to get on any slicks quiet yet (completely speculating from his posting). While I am not a big buyer of the "slicks don't help you learn, they only cover up mistakes and allow you to go faster" philosophy that Instructors tend to teach, I still think you shouldn't be on slicks until you are comfortable with the limits on street tires, especially on high speed corners.

I am a little late to the party Steve, but summit has those allstar performance sleeves for sale and the QA1 springs on there are cheap as shit. I just got my springs+sleeves for $313.

If you are on R-package bilsteins, stay on them and get some springs ~400 or less. Seems you already got the sways under control so you should be ready to go! Just gotta get some wider wheels and 205s/225s (whatever you like, personally I am sticking with 205s for now after finding the traction to be plenty).

With that said, your body roll pictures aren't too shabby, you can see how much my car pitches and rolls in turns/under braking in my videos and the pictures on MFz. I had to stop braking as hard on turn 11 and 1 (CMP) because my rear would unweight so much that it would get squirrelly and almost kicked around on me a few times!

My thanks to everyone who contributed here. I ended up with ground control sleeves on NB hard Bilsteins with Brain's 448lb 8" front springs and 275lb rear. I am using the FM 1" front sway set full stiff and the FM 5/8" rear sway set full soft.

After some fidgeting and settling I got a ride height I can live with. It is slightly higher than what is stylish but will allow ample travel under load if I'm onto the curbing. To go any lower I would need a 7" front spring because I am adjusted all the way down to the clips that hold the adjusters up. When I mount the 15" wheels it will fill the fenders better and I need to leave room for them to move as well.

The NB hard Bilsteins have no trouble with these springs. I was very surprised how well they worked and believe I could go to quite a bit firmer spring rates with them without issue. It really does ride better than stock to me. It has a comfortable firmness and I am ready for the next trackday to see how it does.

Glad to hear the sleeves worked out!
