s2000 Settings

Hi Guys,

 

Tony set the car up for me about 6 months ago and got it nearly perfect, the only issue was a siezed caster bolt that honda promised they fixed!

 

Anyway, the car hasn't been touched since then and I'm about to polybush everything which is going to totally screw the geo. I don't want to drive the 120 miles to WIM after doing this so have found a local place in Christchurch with a Hunter.

 

I have the original printout from WIM which they are happy to use but I want to make some changes as i've recently put some Yoko AD08's all round and it's changed the behavour of the car. The back seems fine but I might go with 0.10' toe each side rather than 0.06 as there is a little more oversteer now and the toe arms will be polybushed so should have a little less flex but the biggest issue is up front. The steering is now really really heavy. I know this will be down to better tyres, softer compound, sidewalls etc but I'll be sticking to AD08's from now on so need to get a setup for the front that works.

 

Current front settings:

 

0.50' Camber

6.50' Caster

0.00 toe

 

Can anyone give me any pointers? I know the caster settings will alter the steering weight and self center, but which way do I need to go? Also, there is so much grip up front now that i'm wondering whether to go back to stock camber to save wear on the insides. I believe the stock fron camber on MY06 cars is 0.30'.

 

Any help would be much appreciated.

 

Thanks

Hi Chris

 

I would keep the camber at -50 but back the castor to 6 degrees. Also next to no toe on the rear if it's on poly's and soft compound tyres.

Cheers Tony, super fast reply.

 

Do you mind if I ask why you would have next to no rear toe? I know the stock setting is someting stupid and the car has an awful rear wheel steer issue which I hate. But would running no toe on the back cause an issue with stability given that the stock setting is something like 1 degree?

 

I'm hoping that polybushed stock toe arms will help this a bit, if not I might need to look at replacement toe arms with speherical bushes.

 

Also need to talk to you about a wheel refurb at your new unit. Not going to be able to make the open day but any idea how long before you'll be up and running.

 

Thanks again,

 

Chris

The wheel plant is a few months away.....

 

Toe is a compliance angle so not required on poly's. I would add a little rear toe to help the tyres get up to temperature, say +10' each side.
