Default higher spring rates and rebuilt koni's help

I'm thinking about the '08 autox season and trying to come up with a budget for the car, events and whatnot. Couple of the things on my list to do is have the Koni's rebuilt and get new springs with higher rates. I don't know much about the rebuliding process and whanot. Just looking for some advice, general info, and recommendations on places to have the work done. Also for some suggestions on spring rates.

Currently have Koni Yellow Sports with 450/550 Ground Control coilovers.

Thanks!

IIRC, only Pro Parts, True Choice and Koni are authorized to rebuild the Koni's. How hard core do you plan to be? If you're a regional only autocrosser in a dual purpose car, you might want to hold off on the revalve. The setup you're on right now is very competent, so unless you're definitely being held back by the suspension then I'd suggest spending the money on schools/seat time.

Trying to be as competitive as possible. For '07 I did about 20 events placing very well for my first real competitive year. I know I have much improving to do as far as my own driving potential. I did a couple Novice schools along with a lot of "social" learning from much more experienced competitors. For '08 I plan for more events, schools and even some HPDE to better my driving. I'm not planning on having the new suspension installed untill the middle or late season. This is just to gather information on the process, learn about what spring rates would be ideal for the shocks, and trying to gather a cost figure to make up a budget.

Thanks for the info solo-x!

The "standard" revalve is their SPSS3 valving which is generally considered to be good for rates up to around 1200#'s. I would also suggest getting the fronts shortened to pick back up a little front suspension travel.

Spring rates are going to be dependent upon whether you want the car to be better on track or for autox. Nate would probably have better input on autoX rates than I would... Track rates you'd probably want to go up to around 650-800F and 900-1200R with a smallish (or no) front bar and a big rear bar.

Yeah i'm deffenetly interested in getting a little more travel. I dont have very much travel even with the extended top hats and my car isn't extremely low, about 1 finger gap between tire and fender.

The car will be mainly used for AutoX. I'll do schools for track but wont be competiting, just looking to get experience and learn something different. Along with the 450/550 springs, I have a 22mm rear sway bar, strut bars, bushings, with 205/50R15 RT-615's. What would you think about 700/800 springs?

700/800 is a good middle of the road compromise that most people will find works well for both track and autocross. I actually ran a similar setup on my EG Coupe in STS for a couple of years. I prefer a bigger then stock front bar though and used a GSR/ITR front bar with a 23mm rear bar. As you progress, you may find you want to make some small adjustments from this point, but it's a good, aggressive next step. I do hope you aren't planning on DD'ing the car though. I did for two years and will admit that it wasn't the most pleasant ride in the world. Watching the rack on my female passengers bounce all over the place was fun though!

Heh, I just received my set of 550/600 spring to replace the 400/400 rates currently on my STS Integra, and the gf has already announced that we're only driving her car when we go somewhere together from now on. Who knew new springs would save me gas?

Women shake in different areas.. with a stiff set up.. & if your gf is top heavy... she might be needing a sports bra when riding with you.
Take her up on the use of her car, and save a few bux for your next purchase
