Parts Shop Max 12KG MAX Super Light Linear Spring 61mmID 180mm Length ~ Pair
Listing is for:
1x Pair of Coilover springs
Springs shorter than 6" must use helper springs sold separately. If you are putting 20KG plus on a McPherson strut car like S13 & BRZ, you will need helper springs.
This will make sure you're not topping out your shocks, which will damage the shock.
However, 20KG+ can be used on a big body Lexus and other double wishbone cars without helper springs.
Helper springs are recommended whenever they can fit your coilover, because it helps static ride height exist in the middle of shock travel, therefore helping the wheel droop out while traversing driveways & also helps dial in the compression travel bump stops.
You can buy our progressive micro cellular foam bump stops separately to achieve a safe suspension travel that is comfortable on its initial approach to end of travel.
