Ive always been told that my RST handles well, and it aint got too much done to it...
So if your not digging too far into your pockets, just go for something simple like this:
Top adjustable Konis
Eibach springs (-25 or -30 i cant remember)
Polybushed everywhere
7.5"x16" rims, with 205/45/16 tyres.
Cosworth brake conversion too...
Micky can vouch for it at Croft last year!
