Greetings RC owners!

Some of you may have already read about the great reviews our Ultimate Steering Response System (USRS) is getting on the ISF forums, but this upgrade will also transform the steering response and handling of your 2IS as well.

One thing that is important to emphasize is that this is not just a replacement bushing. We have designed a bushing/housing system that eliminates all the thrust movement of the standard or upgraded bushings.

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!

I'm going to have these installed on my RCF. Is this a DIY job or is professional installation recommended? Does it come with install instructions?

If you email me (Rafi@RR-Racing.com) I can send you a PDF of the instructions and you can decide if you want to do the install.


The install is easy, but it really helps to have a lift because it makes life so much easier. A drive-on lift or regular lift will work. You do not need to even take the wheels off.
