Just in case anyone missed the review threads of our Ultimate Steering Response System (USRS), we are posting the details in the new product forum.

We want to emphasize, that the USRS is not just a replacement bushing. It is a bushing + housing system that completely changes the design of the OEM bushing from a simple compliance bushing, to a thrust loaded high performance bushing/housing system.

All current aftermarket offerings address the lateral deflection, but do little to eliminate the fore/aft deflection that leads to dynamic toe changes under braking and cornering.

By eliminating excessive movement of the soft stock lower control arm bushing, we dramatically improved steering response and feel during hard cornering, without the excessive vibration and harshness associated with race-only hard spherical bearings. As illustrated in our image gallery, the OEM suspension control arms, under braking and cornering, actually move with respect to the chassis. This results in increased understeer, non-linear steering response, and reduced stability under hard braking conditions, and in many cases excessive inner tire wear, a well known problem on many Lexus models. We have designed our USRS to significantly reduce all dynamic toe changes and lateral deflections!

Please watch the video below for a detailed overview of USRS and on-car comparison between USRS and the Lexus OEM bushing.

Summary of Features:
•Our bushing virtually eliminates unwanted suspension movement, that lead to changes in toe, caster, and camber while turning and braking.
•Our redesigned housing increases static caster by 0.3-0.5 degrees. Increased caster improves steering feel and camber gain when cornering.
•Comes as a complete and assembled bushing & housing assembly - no costly labor and hassle in pressing out old OEM bushings.
•Redesigned 6061-T6 lower control arm housing designed to be stronger than OEM to withstand increased thrust loads.
•Extremely tough 95A durometer polyurethane bushing -- backed by our lifetime guarantee!
•Polyurethane bushing features fully fluted design on shaft and thrust side for enhanced lubrication. Also features end seal to keep dirt out.
•Track tested and track proven on our shop IS-F!


All components in this product are proudly engineered and manufactured here in the United State of America.

And here is the video showing:

(1) ZERO lateral deflection under aggressive cornering
(2) ZERO rearward migration of the lower control arm during braking
(3) MINIMAL lateral deflection of the bushing during braking
