Hello All. I've just bought my first S2000 about 3 weeks ago. I'm finding the car a little 'jittery' and hope someone can advice on replacement spring/damper units. Ideally i would like something near to the original spec. Many units I've seen so far want to lower the suspension, i'd rather not do that. Currently the car has original front units & Koni STR T on the rear. The car is fitted with Toyo T-1R tyres. Cheers

jittery ?
maybe fit oem then ?

Don't just assume something is wrong, it might just need the geometry set up properly, get that done first before spending out shed loads.

I've read Toyos have soft sidewalls but running a stiffer rear and STD fronts sounds a terrible idea to me

I would change the back to STD and Geo it

I've started running on Michelin pilot sport 4's, sidewall seems as stiff as the old Bridgestones, very good tyres indeed!

BTW Boilerboy, you haven't stated the year of your car, that makes a difference as the suspension went through a number of changes. (and we all have AP1's in the UK, AP2 refers to the 2.2L engine in the later US and Jap cars).

Thanks for the replies so far. My car is a 2002 . I've been having a look a the BC range of coilovers . Anyone got any thoughts/ advice on these ?

There is no "AP1" suspension, of course. (And all the cars in the UK are AP1s anyway.) Honda changed the suspensions every two years like clockwork. 2000, 2002, 2004, 2006, 2008 are all slightly different. Smaller wheels, higher profile tires pre-2004 can make a difference.

Our cars are also tire pressure sensitive.

I've got the Koni STR.T Kit on mine (2000 car) and it feels very composed, that's with the included H&R Springs. It did however feel very unstable until I had the geometry set, and it turned out both rear wheels were pointing slightly left (toe-out one side, toe-in the other) and after that was resolved it felt fantastic.

I went through thinking it was tyre pressures, worn bushes, a sticky caliper (as it steered on/off the throttle) but overlooked the most important part which was making sure the wheels were pointing the right direction!

When you say jittery do you mean vertically over bumps/rough sections of road etc. or does it feel unstable in terms of moving unpredictably when you're cornering?

I'd get the geo checked first. You'll probably find its way out. It makes a massive difference on these cars.

You may also find that it cannot be adjusted as you have seized bolts. Mine was a death trap until I had them replaced as under heavy breaking the rear would do a little dance.

The car is unpredictable when cornering also at higher speeds it feels unstable. any ideas on where I can buy new eccentric adjuster bolts for the suspension arms?
