Are these the right coilovers?

[Ed Doe]

I run 400lb on my 306 now, and that's with 24mm torsion bars at the back, correct valving on the dampers. It is f**King hard to be honest..

On a daily, I wouldn't go above 300lb and 21mm TBS.

Point is though JP, your rear is stiffer to compensate for the stiffer front (inb4giggidy). Just whacking some 350lb main springs on the front, with stock hdi tbs and arb on the rear (even if you uprate the dampers), you're going to tend to understeer on the limit for sure.

Far better to match the spring rates at the front to what set up you've got at the rear, and then spend your time tuning the rebound settings and adjusting your front toe to give you the handling characteristics you desire imo....
