I like where you are thinking. I guess when I had my STi i ran softer in the rear to be able to put the power down. Front wheel drive dont always have to worry about that. Ill be ordering springs soon once I decide on a rate. True dont want to go to stiff, but i want to keep the 255 off the fenders.

If i go with what you say I would go 448 front and 506 rear. Thats just the way swifts come in a 60mm ID 9" long.

Im alway waiting on powel to get some XXX bars made and in stock.

 

So, going by what wangspeed said about the stockers and pedders claim of "30% stiffer then stock" the pedder would be 585 lbs at 2" compression. But, that assuming pedders number is accurate and not just maketing bs. I still say 10k front 12k rear and buy a couple sway bars to fine tune it.

 

hmm you make a valid point as well... damn! hah

 

John's said the spring rates of Pedders v stock is similar, but the rate of progression is different. Makes sense since I feel that they are a very, very mild upgrade from stock. Honestly, I think the Konis alone make a bigger and better difference than just the Pedders.

10kg/mm front is pretty high. Probably okay for a smooth track, but I think you would be skipping on an autox course. Same goes for the rears. They're not unreasonable for a smooth track, but I bet it gets annoying on a small lot. Plus I'm not sure if the KW v2 can even control spring rates that high very well. I'm guessing no.

 

Great point about the shocks controling that high of spring rate, maybe I was a little high.

 

all good info either way. 8k front and 9k rear might be the numbers... Playing around with the rear KWs and they are quite nice! I dont have to remove them to adjust the rebound like I did with the konis.

Thanks for all the help and talk on here quys! Hard doing something no one else has... maybe for good reason? lol

 

Where did you find the Team Dynamics?

When you sort out the spring mess, maybe I'll go the same route :P

Half tempted to go AST 4100 and wait, but I shouldn't... The KW v2 route would be cheaper. Really I just have 2 reasons I want to do it. One is to lighten the strut weight up front, and the other is to increase spring rates, mostly in the rear. Pedders are soft in the back. I notice it most when I have a passenger in back or trunk full of crap. My FXR retros start blinding people, even though I have them aimed low for empty load.

 

haha i thought about ASTs but like you sau KW V2s with different springs all together will cost me less than 2grand. Compared to 4-6G for a custom setup. I think I have an idea now what to do. when I get them in ill let everyone know. still a few months till racing starts up here in wisconsin to really test them out though.

 

Cobalts are setup stiffer in the rear from the factory, and all the race cars. Only the aftermarket coil setups are softer in rear.

 

AST 4100 should be under 2500 without strut mounts based on their prices for other cars which are as low as 1800. That's reminds me, are you running stock or the GC strut mounts?

 

Well when I emailed them they would be a bit more just cause they would be a custom setup.

I am using stock as of right now. I emailed GC to make sure the 3 post mount would fit a cobalt. Still waiting on a reply. That maybe a mod for next season, kart and Autox budget... Gota keep within it. Might just go with camber bolts for now.

 

I just asked GC about the plate last month. $329, Cobalt specific, fits underneath, includes a perch for 2.5", but I'm sure you could get them to do a 60mm. Might need to measure the shaft size for them.

 

did they give you a part number at all? Those would be a lot better than camber bolts but also expensive lol. I may have to put these in the budget.

this is the one i emailed them on.

 

Thanks. I plan to follow this thread closely. I have autox'ed for a few years, but never in a fwd so this will be a new learning curve.

 

You definitely got the right fwdriver to start with

 

Why is he on here then, shouldnt he be on 1989hondacivicSi.com?

 

lol

 

alright, talked to evasive motorsports on my springs and they will be on order soon. They were told by swift to go with a 65mm ID spring cause the 60mm wont fit on that car.

I am going with 9k up front and 10k in the rear.

The reason I picked these rates.... BC coilovers run 8K springs all around, I wanted to go a bit stiffer than that all around.

 

The most advice I can give to a new autocrosser is RACE IT STOCK!!! Get used to it, find out what the car likes, and doesnt like. Know your car before you change anything!! In the 1 1/2 years I have had my cobalt i have about 48 events total on the car with race tires and street tires.

 

I don't have the PN. That's not it though. It looks like this:



I confirmed by emailing and asking about it. Try emailing and following up with a call.

 

Well I am not a new autocrosser . I have autocrossed on and off since I was 16. But all of my experience has been in RWD platforms with the majority of time being in my Turbo II powered 1st gen rx-7 or my dad's BEGi turbo'ed miata lol. The Cobalt I bought already has light mods that I will run with but planning to take it slow on further mods.

 

Tennessee is full of turbo miatas

 

Haha that is true. However we have one really bad ass supercharged SSM miata too lol
