i have a 04 s2000, lowered it with some springs about 1", drove around for about 8 months, the car started pulling the the left and then pulls back to the right when u give it some gas at high speed, tires r good just changed, and it waves around alot. i was thinking it was the shocks or some crapy tires. i have put the original springs back on and it still does that. confused HELP...

 

are you burning out? or launching?

 

Have you had the car re-aligned? Checked tire pressures? Sounds very simple, but S2000s are VERY sensitive to small changes like that.

5psi loss in my rear left tire caused the car to pull to the left significantly when gassing it.

 

get it re-aligned...most likely you have some toe issues....
since you lowered it you've changed your camber and caster as well....
since you've put ur springs back on your tires probably have memory wear...
if you've still got a good amount of tread left i'd say ride it out...if not, get new fronts and start new....however if u know the stock specs...you could change your ride height, have it re-aligned and still be close to factory
s2k's are also have some gnarly bumpsteer....but for sure get it re-aligned

 

Get your camber and toes checked out... or you will be buying new tires very soon.

 

check your tire pressure and then get a full alignment.

 

Tire pressure, bad tires maybe, check to see if you have a nail in one of the rears.

 

is there any dif in the shocks, are the front ones dif from the rear ones, i got some new tires for the front, once i change them ill c if it makes any dif. when i just bought the car the front tires were bad already but only on the inside part of the tire, like the camber was off on both front tires, but it was driving normal and then changed the front tires and it started being weird. thats all before i lowered it. the car shifts really rough when its lowered but as you put the oem shocks back on it shifts smooth, or is there anything that could fix that because i really want to lower it and keep it that way. dont want to brake it and pay more later as usuall.

Get the air pressure checked. The air pressures must be exactly the same side to side. 32 is your stock COLD pressure (hot pressure is hard to predict, but use 36-38 as a good hot pressure number. Hot pressure means you drove the car more than a mile. Cold pressure means the car sat without being driven for 3 or more hours.)

Get your car aligned. Alignment on those cars is crucial. Inside tire wear is normal for S2000s as they have an agressive factory alignment setting for toe.

Get it aligned to factory specs if you're just street driving it and lowering it for show. A performance alignment depends on your set up/driving style.

Negative camber usually doesn't wear tires. Toe wears tires. Since the S2000 has an agressive toe setting, adding negative camber will wear tires because of the toe setting. The only reason for me mentioning this is to make your head spin.

What setup are you using to lower the car? What do you mean shifts rough when it's lowered? You mean when you hit bumps, the car bounces? Do the bumps feel a lot harder than usual?

Usually OEM setups will be softer than a lowered set up. You have less travel...so the springs and dampers have to stop the car from bottoming out in a shorter distance than stock.

The front shocks are different from the rear shocks. Why?

 

update on problem?

did you get driveshaft spacers? here:

 

sounds like tire pressure.
