Hi guys,

We have a local time attack event coming up soon. And my car still suffers heavily from oversteer.

Basicly it's a standard MY00 with Cusco Front Sway and running on 205/55/16 F 225/45/16 R A048 Tires. The rear is a bit more stable after I put on the cusco front sway bar but still too twichy, another big issue is the inside wheel lifting I think. I have been reading the forum a lot, and it seems like the option I have are: 1. Getting Adjustable Front Sway bar 2. Unlink rear bar or change to softer rear bar 3. Change spring or coilover.

The problem is we dont have any of the adjustable bars (Saner, Comptech...) here in UK, and I dont have the budget for coilovers and changing spring just seem to have the 9 year old oem shock under damped...

So I'm thinking to either unlink rear bar or change to a MY06 bar, but I cant get hold of 06 bar atm and disconnect the rear bar seem to be the only choice, but that way my rear seem to be too soft and will my laptimes really improve???

Also I'm considering getting 255/50/16 R888s for the back, but i'm not sure how effective it can be if the inside wheel lift problem is still there.

Any thoughts or sugguestions would be much appreciated. Thanks!!!

I would definitely use wider rear tires. For years I have run 245/45 in the back, with 205/55 in the front.

 

Yes go with a wider rear tire, also, go with an adjustable rear sway bar.

Coils would be nice if u had the cash, but just the rear tires and sway should make a HUGE difference

 

Agreed on the wider rear tire. Also, have you checked your alignment settings? You're already running a much stiffer front sway bar and another 2cm of contact pitch in rear will not likely solve the issue if the oversteer is as bad as you say it is. I think you may want to look into an alignment with an experienced pro.

Good luck.

 

None of the proposed solutions will help with inside rear wheel lift -- to fix that, you'll have to bite the bullet and get a bigger front sway bar and/or stiffer springs.

Edit: Actually, it would be more accurate to say none of the proposed solutions are ideal. Wheel lift happens when you get too much body roll and pick the inside rear tire off of the ground. The ideal solution is to reduce body roll by stiffening the front bar and/or spring rates, but softening the rear bar should help as well, albeit while making the car feel mushy (since the rest of your suspension is essentially stock).

 

Is softer or no rear sway bar not an option for reducing the inside wheel lift?

Maybe some one in the US can sell me a Saner bar lol???

 

if the shocks are too old they might have simply worn, or lost compression. i drove my firend's S2000 with worn shocks and its oversteer was too snappy!! when he replaced the shocks with new ones the balance of his car became normal. so just check if your shocks need to be replaced.

good luck,

 

What tire pressures are you running?


What are your alignment settings?

 

UK alignment with -2.2 camber in the back

I tried all kinds of pressure, with rear equal or lower than front at 26 - 32psi when Hot.

 

Well, actually, that's fair, but not ideal. Wheel lift happens when you get too much body roll and pick the inside rear tire off of the ground. The ideal solution is to reduce body roll by stiffening the front bar and/or spring rates, but you're right that softening the rear bar should help as well, albeit while making the car feel mushy (since the rest of your suspension is essentially stock).

I'll edit my original post.
