Yep, 275# is a little soft. That is what I have now and I need more rate. I don't think I'll get a 425# just yet
Maybe step up to a 350# or 375#. I have 750# on the 740 Volvo with Koni sports.
A little feed back on Griggs rear race shock. It is way to stiff a valving for the street but maybe you would like it. You would love it for the track. I need to revert to the sport shock for the rear.
