UMI's Stage 1 handling kit is the cost effective way to refresh your trusty 2nd Gen and bring the joy back to daily driving. The kit includes 2" UMI front lowering springs (600 lb/in rate) and rear lowering leafs (175 lb/in) which takes away that floating feeling so common with soft springs. UMI's slim monotube shocks front and rear control body movement and improve response when hitting transitions on your favorite back road. The 2nd Gen platform responds nicely to the heavy duty 1-1/4" front sway bar which prevents body roll and makes the car much more fun, and easy, to drive. We also include a new poly shackle and rear isolator kit to refresh that commonly corroded area. The UMI Stage 1 kit is designed to work together properly to offer an enjoyable ride and sporty feel. This kit is 100% Made In USA and is suitable for daily driving as well as corner carving.

What to Expect Upon Delivery

Always inspect your items immediately upon receipt and notify us if there are any concerns, damages, or missing items. Please verify that all boxes and parts are present and correct using the packing slip or instructions before starting installation or bringing your vehicle to a mechanic. We are unable to assist with any costs accrued from delayed installs due to missing parts.

If the cancellation request is received within 24 hours from the time of purchase, these fees may be waived.
