regarding destorying the OEM shock, is it how much you lowered or is it the spring rate you use?

 

stockae92,

No problems with spring rates.
I just think that the stock shocks don't perform well being too low.

 

oh

what i meant was what destory OEM shock with lowering spring is the spring rate not the fact that the shock is too low?

(since the OEM shock's rebound damping is tuned for stock spring rate, so the lowering spring with higher spring rate, i.e. greater rebound force, will constantly put my stress on the shock's rebound damping)

i'm not saying it will, i am asking will it?
(even if it will, the OEM shock may be strong enough to hold on)

 

stockae92,

Ahhh...I get it.

No problems here. I have over 50,000 miles on the stock shocks with the comptech coil overs.

Plenty of track and autocross events...and I drive the car plenty hard on a daily basis.

 

Who sells them, and how much are they?

 

thanks Unicron

oh, do you need to do alignment every time you adjust ride height?

(my thought, set it up 1" lowered for daily drive. for track day or autox, lower to 1.5", which will give more -ve camber hence better cornering? can it be that simple? )

now, same question as gernby ...

 

As a general rule, do an alignment everytime you adjust the height of your ride.

As an alternative, y'all might want to consider going with Ground Controls. Excellent price. Quality stuff. Same go-kart ride. I was considering going Comptech, but they were going to charge me $450 v. the $400 GCs. Plus, you can't pick out the spring rates like you can with the GCs.

If you decide to go with KG/MMs, make note that the drop is very conservative and later on once the stock shocks blow and you decide to go with Konis or something, you don't have that assurance that the suspension components have been matched together. With GCs, I know for sure I have one company that has done some testing and has several options for me to choose from, shocks-wise. Food for thought.

I have a one finger gap in the rear and a tight 1.5-2 finger gap in the front. 340/380 rates F to R on stock shocks. No ricer-bounce.

Thanks to pfb for his recommendations.

 

are just going with CG spring or spring and shock?

is CG spring adjustable?

one question, how come you have 1.5-2 finger gap up front but 1 finger gap at the rear? (front higher than rear? or the rear fender is lower than the front?)

how's the price of CG spring compare to comtech spring?

 

There is a possibility that the suspension geometry might be such that lowering the car before a competitive event could "optimize" other aspects of the alignment. For instance, we know that lowering the car will increase negative camber. Does anyone know what effects lowering the car will have on caster and toe? If caster doesn't decrease too much, and the wheels toe out a bit, then that might be optimum. Then after the event, the ride height could be set back to where it was, and no alignment would be needed.

Is this too far fetched?

 

I believe the Comptech springs are the same rate as the stock springs. Do a search and you will find more info when the search function is restored.

Originally, I wanted to go with GC, but they don't offer stock rate springs (or, at least that's what the guy told me on the phone) at 218 front, 291 rear.

The next choice is the Comptech Springs which is $300 more than GC. Import Development has them for $650 a set which is $50 cheaper than ordering directly from Comptech.

Thanks for the info, Unicron.
