Default Rear Coilover rate

Well, I have tried the rear at 275/lbs and it is a little soft for my taste.

Is 300/lb the next logical jump or should I go up to 325/lbs ?

I am looking for crazy stiff, the front is 400/lb and I imagine that 300 or 325 is going to work for the rear.

Carroll Smith used to say don't bother with spring changes less than 10% different, so I think I'd go to 325 and go from there. With only 400 front, though, I wouldn't go over 325 without increasing the front rate as well.
