New addition to our Lowering Springs series. We’d like to introduce our Spec-R springs for the 2022+ Lexus IS500!

Drop height is -1″ in the front and -0.6″ in the rear with springs rates of 6.5kg/mm for the front and 10kg/mm for the rear.

Once installed, you’ll find that we’ve kept our 3 engineering characteristics. Modified the ride height to maximize optimal suspension geometry, further increasing spring rate to enhance overall performance. And maintaining an optimal ride comfort for street use.

We are pleased to announce our new line of High Travel Front springs designed for Modifieds. This spring in particular has been in prototype development for the past year and has scored numerous wins in the IMCA Racing as well as USRA (United States Racing Association) events. 

These springs were designed to allow the car to get down faster on the front so you don’t need to have all the tie down built into your shock. With 2 active coils, this spring works at a much higher frequency, and like all of our springs they are made from our very own HS5.TW material that’s manufactured in-house. 

They are currently available in 3 rates.
