Spring Rates for carpet - 201XM

[jph]

Hi Guys,

Finally got my 201 XM last week and carried out a full strip & rebuild over the weekend.

So far so good and I'm really pleased with the purchase

I'm going to do some racing at a local club indoors on carpet and i'm wondering what make of springs and what spring rates I should be using?

The car came with Tamiya big-bores complete with the the 3 options of front spring and 3 options of rear spring but they all seem too soft for high-grip carpet when I tried it on Sunday.

All suggestions are welcome

Jph
