Once you have the tyres - look out for some fast road discs and pads. I can recommend carbon Lorraine Front pads and group n discs. Ktec are the cheapest retailer for the pads!!!!
I swapped to poly bushes very early on. Pretty tough getting the inner ARB ones on hehe. I swore at them maaaaany times under the car trying to out them on
I like them, it all helps toward a more focussed car imo.
