Best spring weights for the track?

[Ianr]

Very interesting thread Sylvain - I'll have to see how I get on with my springs 350 front, 300 rear (was 250). I'm going up due to there nearly always being two in the car weighing in at 30 stones (too many pies) but would stay at 250 if it was just solo. Chris (CTW) went to 350 / 300 and reported better handling. I suppose it is what suits you. I always remember motorcycle racing many years ago where the suggestion was soft springs with hard shocks, perhaps Alga has it right?
