Stance GR+Pro for Nissan 240sx S13 89-94 S13 with LS1 Swap
Product Description 
GR+Pro coilover has all the features of the GR+ but adds the benefit of a helper spring. The helper spring allows the shock piston to be placed in the optimal position within the shock body, increasing rebound stroke, and maximizing articulation on cars with minimum suspension travel.
Available now, includes rear traction springs for better dampening.
