GT3/GT2 Rear Spring Kit

Description: Now available from Tarett Engineering, a direct replacement for the factory progressive rear springs. Until now, there was no way to change the rear GT3 spring rates without having to buy a complete coil over kit. Now you can replace your rear springs with 60mm linear springs and your choice spring rates, while retaining you PASM system. All at a fraction of the price, and with equivalent performance of a premium coil-over kit! The kit includes the top 60mm spring adaptors, main coil springs of your choice, tender springs, and the main/tender spacer. We chose Swift springs for this kit because they are the lightest, strongest, and highest quality springs on the market today. The adaptor is made from aircraft quality 6061-T6 aluminum alloy for it’s high strength and light weight, and is anodized or signature red finish for corrosion resistance. For significantly stiffer spring rates, we recommend also having the dampers revalved by Bilstein, for a further performance improv
