I just bought a suspension for my CRX w/ 10k front and 12k rear spring rates. For the most part it'll be a track car and a couple times a week it'll be driven on the streets. i have a pretty high tolerence for things like this but is this manageable or is it too ridiculously stiff? TIA

 

Those spring rates probably aren't too high for limited street use as long as you aren't doing any long road trips or driving super-bumpy roads. The 600+ lb/in rates in the rear will probably make the ride pretty miserable on rough roads though. It should be a decent track setup given shock valving to match. Is this the PIC coilover setup?

 

No its Ksport. Hopefully they are decent. The guy i bought them from said they will be custom valved for the rates. The OTC rates are 10k front/6k rear.

 

anyone else?

 

What little research I've done on the KSports for other applications stated that they were "custom-valved" for the springrates, but I couldn't see a dyno chart of their shocks or a dyno to see how they "customize" the valving for a WRX application because that was "proprietary" information. Seems a little silly to me when most other custom-coilover companies will readily give you that information so you can really see what their product does, but the extent of information I got about their race-valving was that it is "very stiff and bumpy". As much as "stiff and bumpy" is a standard which we should strive for, I'd rather see some numbers as a bare minimum.

 

Ksports use tokico shocks, right?

 

I doubt they do, they look pretty much (seen them in person) like any cheap adjustable coilover to me...

I didn't know tokico was expensive

 

imo, tokico produce better quality shocks than any kind of noname JDM-omni-racing-sport-bling-Megan-boum shocks.

If I'm not mistaken, most of those no name companies don't actually make the shocks. They just outsource to other companies, including tokico occasionally.

 

If you track or autox your car a lot it wont be to stiff. If you drive it a lot on the street with shitty roads you might want to think twice about it. Im running 12k/10k omni's on an EF and I love them, Id say do it if it doesnt see the street a lot.

 

I think that is too stiff. I have seen very competitive CRX race cars with all four corners in the 450 - 600 lb range. Stiffer is not necessarily better, and I think this is overboard. I go with the philosophy of using the lowest possible spring rates without compromising handling....

 

I run a 400 f / 600 r setup on a very competitive ITA/H4 CRX track only car and I think you'd be nuts to run those high rates on the street. I've occasionally run it on the road [ don't ask] and unless the road is billard table smooth, it hurts, alot. Run a stock bar up front with a 26mm rear bar with revalved Koni's all around

 

well im expecting to receive these in a day or so. the car is going to see very little street use, once maybe twice a week. when i do need to use it i will be commuting 40 miles in that day. lets see how it is...

That sounds like an enormously bad suggestion. To the OP, don't do this, especially with the suspension you're buying and/or if you have limited track experience.

 

ya snap oversteer is not fun when going fast for the first time

 

lol tell me about it!

12K is 671, 10K is 560. Not too far off of you range.

I ran 12k/10k on my (heavier than a CRX) integra on the street and it was totally fine. 800+ mile trips with no issue. Any heavier in the rear and it might get painful.

Don't mix Integra/later Civic/Prelude spring rates with CRXs as it is easy to go overboard. Although there are many geometry differences, the weights and especially the whyeelbases make CRXs much more conservative than Intrgras. Be careful, this is a common misconception if you overlook a few key factors.

Sorry for the grammer error. Meant to say "I run a stock bar with a bigass diameter rear bar". And no, I wouldn't recommend any street car run this type of set up.

 

Thanks for the clarification
