First, we refined the Rear LCA mount for the IS RC and GS with a progressive polyurethane mount from SuperPro for performance street driving and tire saving.  Now we release our uncompromised track performance solution that has been tested in the 25hr endurance race at Thunderhill on the N1 Racing IS250 Lexus factory sponsored car.  This is the same race Lexus did final testing on the UR engine used in the RC-F.  This system provides precise control under braking and acceleration and is especially designed for use with the extreme loads of R-comp tires and larger brakes like our 15" front BBK.  With complete fore and aft rigidity, this zero deflection mount is a must for all track going cars looking to improve driver skill and reaction times while also allowing caster offset for enhanced steer in control.

 

 

 

ZDS: Zero Deflection System

-Solidly mounts the front LCA in compression and rebound under heavy loading.

-Allows caster offset adjustment via spacers for sharper steering initiation.  Couple with our #1 bushings to reduce stress on the #1 arm mount.

-The most precise and responsive suspension motion available

 

The Components:

-Precision machined Bearing cup to utilize factory mounts and to align thrust load accordingly.

-Massive FK Bearing Precision 3P spherical bearings with PTFE liners.

-Stainless steel mount spacers with caster offset adjustment.

 

 

The Install:

-Remove under cover around oil pan to expose rear LCA mount.  Lots of 10mm hex head screws.

-Loosen LCA rear mount nut.

-remove 2 chassis brace bolts as well as the large subframe bolt. 

-Remove nut/bolt combo on small side mount of bracket.

Remove rear mount LCA nut.

-Choose Preinstalled option to receive a bolt-on bearing installed in a factory bracket.

-Remove the old bushing entirely from the factory aluminum cup.

-Press in bearing cup housing from the front of the bracket, flange forward.

-Install transition spacer (the one with large chamfer) first, then install offset spacer to increase caster or no spacer to retain factory geometry.  We suggest factory geometry first as the benefits of this system are drastic and improved caster may not be required on vehicles lowered more than 1" due to factory caster gain.

Reinstall rear nut to hold bushing in place but not to final torque.

 

-Reinstall 2 bolts plus nut  and 2 bolts of side bracket.   Long bolt through side rail bracket Torque to 204Nm/ 150ft-lbs, short bolt with nut 86Nm/63ft-lbs side rail bolts 50Nm/37ft-lbs

 

-Verify clean cyling with suspension by loading and unloading.  Apply final torque to LCA post nut. Torque to 113Nm/ 83ft-lbs.

 

Maintenance:

-Precision bearings are delf clearing and permenantly lubricated with a PTFE liner, but the tight F2 bearing fit means that sometimes they can squeak at low speed. If this happens, follow the rewetting proceedure shown on our youtube video on relubing bearings with PTFE dry lube.  DO NOT USE GREASE as it can cause bearing separation.
