Rob & I calculated the motion ratios for the coil overs, so here are the final spring & ARB numbers ...
Springs & ARB's:
Front Spring Rate: 470# *
Front ARB Effective Rate: 1050#
Rear Spring Rate: 318# **
Rear ARB Effective Rate: 400#
*I would err on the stiffer side & go with 500# front springs ... and if during testing you are not getting the car to travel the front end enough ... and the car is tight or pushy in the middle ... then you can step down in front spring rate to 475# or 450#. This stiffer front spring will also give you a bit more confidence on corner entry until you get used to the high travel.
** I would err on the slightly stiffer side & go with 325# rear springs ... and if during testing the car turns well but needs more grip on exit ... you can step down in front spring rate to 300# or 275#.
