XRAY - Model racing cars

Hi all,

I've just joined the site and wondered if anyone help me with a basic foam setup sheet? I race at my local club on quite a tight carpet track. I'm having awful trouble trying to set up my car at the moment with the biggest problem of the back end sliding about and I just keep spinning out when I corner at any decent speed. I currently have the following setup which I have been recommended by the top driver at my club;

Fixed front spool
Geared diff in the rear with 1000 CST oil
5mm ride height all round
3.5mm droop all round
Shocks have original oil that came in the kit which I think is 35WT?

Any help would be appreciated!

Cheers Dan
