I've been tring to find out what the spring rate for h&r coilovers are. Why does h&r not post these numbers for the tC?? I've even called them up and the rep. on the phone had no clue. He asked me why I wanted to know the spring rate and i expalined to him I wanted to compair h&r to all the other coilovers available for the tC. Every other company gives the spring rate. I hear good things about h&r from the FEW post by the same people. It makes me wonder if maybe it's because they spent too much money not to be happy. I don't know... but I do know if h&r would post the spring rate for their coilover it would be alot of help. Or maybe someone else out there knows
