Is there one more spring on one side or a higher spring rate? Just asking because I sent mine to powdercoat and the pads melted out, was reading some guys order the same spring both sides because their cars sit more level, was considering that.
The right side is stiffer and a little more arch to compensate for the extra torque that goes to the right rear tire on launch due to the spin of the driveshaft through the axle... The right tire gets more torque so they make the right spring stiffer....
