10 Best Best Coilovers For Lexus Ls430 Reviews

1. Godspeed Mono-SS Review

When we set out to find solid suspension upgrades for the iconic UCF30 chassis, we knew we had to look at options that respect the luxury roots of the flagship sedan while tightening up body control. The Godspeed Mono-SS setup brings track-proven monotube design right to your garage. We found that installing these units completely changes how the heavy chassis corners, giving it a much more planted feel without completely ruining the famous Lexus highway composure.
