My experience with KW'S and then swifts on the car seems to confirm.

They may be soft but the comepression rates, decomepression rates and what not, are matched perfectly. i dont see being better. maybe stiffer, but not better. but thats my opinion based on my knowledge. If you put in aftermarket shocks and springs that were matched id agree. but at that point you might as well get coilovers.

BACK ON TOPIC. the point of the thread is for the best susp mod. IMO id say buy tires (Slicks) if you cant afford them buy sway bars. but like i said before oil cooler and fluids and brake pads are a must before any other upgrades.

i dont recall the number exactly, but the swift spring rate is like 30% stiffer than stock. you are asking the shock to absorb that much harder, i dont believe it one bit that it would be good for its longevity. as far as performance, the difference would be very minimal and there is really no way to adjust or fine tune it. you are better off saving your money on tires brakes and driving classes. if you need to mod, get some sway bars instead as they are at least adjustable.

the z spring is stiff compare to the corvette z51 and rx8, it really isnt all that bad of a setup fpor a stock car. obviously it would be better to have coilover and more front cambers, but some are complete overkil for a street vehicle. also no one ever looks at the class impact and all the other bs should they decide to enter time trials, you can spend your money on a lot better places...

is swift springs made by swift motorsports in norwich ct?

hey cossie i know its off topic but do u still have ur car?

cossie1600 09-09-2011 01:41 PM

Yes, nothing else to buy at this point. Everything else is kind of a so-so option.

Leave it stock, get an oil cooler, and spend money on seat time.

I thought the stock tires were pretty good.

ok for the oil cooler (which I was planning on doing anyway) I think a 25 row would be good for DD and maybe an occasional track day... best brand? GTM, Stillen? Another kind perhaps?

I think they all used Setrab oil cooler cores and they're all roughly the same price. Just pick one I guess. I was looking to get the Z1 oil cooler. Definitely want to get one with a thermostatic plate.

Yeah, I have a guy that gives me good prices usually on stuff and he's very honest... if you guys let me know prices you have gotten and I can beat them, i'll hook you guys up with the price I get.

PM me if you are interested... by the way i'm just going to give you his info... not trying to make anything off of anyone.

Stock tires are good. but NOTHING like a set of slicks. I would try out going to the track on stock tires w an the oil cooler pads and fluids that way u can get a good feel for what the car can do. Also w slicks they dont give u the warning sqeel before they brake loose. they just let go.

I have the 25 row from Z1 and couldnt be happier. Kept my car out of limp mode with back to back runs at the track with almost no cooldown time.

The stock Bridgestones that come with the sports package is great for beginners they're predictable and produce enough grip when your just starting out. Later on you may consider some nice aggressive street tires like RE11's, AD08, etc etc...

But like many have said here brake pads, brake fluid, and oil cooler is a great starting point.

Don't waste your money on slicks as a beginner. They have more grip but don't give you as much feedback before breakaway, definitely something you should work up to IMO. Street tires are good at teaching you how to drive at the limit of traction as you will be potentially at that limit a lot.

Critical upgrades are as everyone else said, pads, fluid and oil cooler. After doing a couple of events I would go for sway bars next, it is a good intermediate step before coilovers.

gtkiller 09-21-2011 02:12 PM

I was considering doing sway bars next any recommendations?

wh1te370z 09-21-2011 03:37 PM

heard whitelines supposed to be pretty good. Stillen, hotchkis


As for the tires. Chris is right, didnt think of that.

^ This. The class I signed up for recently even specifically disallows students in their novice/beginner-level rankings to use slicks at all. Their words: "A driver with out proper training before going to race tires is at a disadvantage, race tire mask many mistakes, don’t allow proper training, and create a safety hazard to lower level drivers, their instructors and others on the track."
