Intrax ?


Optional Spring rates, almost all manufaturers have optional rates these are just the ones I know of:
TEIN HA Series, Turbo AWD 564 lbs/in front 336 lbs/in ReaR, 10/6 KG/MM
A Tein dealer told me that 10/6kg/MM was as soft as you could go w/o re-valving the springs,
He also quoted me $230 for springs purchased separately or no cost to get them as part of a coil-over set
