Im a part time mechanic for a Renault 5 1300cc GTL, It races in the Classic touring car championship,
Its had the usual stuff done, CAM work valves/springs, webber carbs, exhaust system (Or lack of it..) and tripod suspension and upgraded clutch/Flywheel.
It will easily keep up with the 2.8 capris because its so lightweight, I think thats why they spend half the time on there roof..
