SPMS Spring Kit

SPMS Spring Kit

from 712.00

This spring upgrade kit for GT3's and GT4’s increase spring rates reducing body roll, and improving suspension response.

After thorough testing on & off the track, we have found this setup to be ideal when used in conjunction with OEM GT3 and GT4 dampers without needing to be re-valved and still maintaining function of PASM. We chose Swift springs for this kit because they are the lightest, strongest, and of the highest quality springs on the market today. Together with the needed helper springs and spacers, this is a complete drop in spring kit.

Paired with our Stage 1 Suspension kit, this setup is ideal for street and track use.
