No data yet but the supplied springs on the Tein SS coilovers I had on my Matrix worked fairly well and rode very very comfortably, far better than stock on mid settins on the shocks.
But, I was going to go with much stiffer rear springs in order to facilitate rotation of the car into turns for autocrossing. I know Hotchkis runs incredibly stiff springs on the rear of their road race Celica and Wes)he owns their project car) and I have talked about stiffer springs for our project car as well but we are going to test the ones supplied by Tein first being this is an independent rear end versus the Matrix twist beam(not all bad
