You are bidding on 1 SET (2 BUSHES) in Aluminium for the front diff ears. 

Got Axle Tramp? I broke 2 Diffs due to axle tramp. 1 Torsen A series Diff and 1 TRD A series diff. 
We have seen broken diff hats and broken B Series Diffs (6spd RZ). WHY? Because Axle Tramp!

Axle Tramp is the enemy of traction. It overloads components by hammering the drive train until it breaks. 
It's causes are largely due to harmonics in the IRS setup and low traction conditions. We broke both diffs under power when changing from 2nd to 3rd gear while losing traction due to a combination of power, not so good tyres and road surface. Once it gripped, it chipped the teeth on the crown and pinion wheels. 

Racetune have engineered a solution based on our own experience and existing products and have made it accessible to all. 

Factory bushes are nearly impossible to find in stock world wide at the same time and are more expensive!

We have engineered a unique solution with the ease of installation with hand tools. You may need a press for the front diff ears depending on your diff setup and the rear diff bushes are the weld-in type. 

Engineered in Melbourne, Australia.

Real world results and info when using a full set:
Our customer feedback from installation and from our own car install is as follows:
  • Car is more predictable and more fun to drive
  • Doesn't feel unsafe, awkward or unbalance when drifting 
  • Tyre ware on semi slicks is more even 
  • Drag racing - minimizes axle tramp to just the spring harmonics which you can dampen out with the shock
  • Diff pinion angle doesn't change under load - direct transmission of power
  • Eliminates all axle tramp caused by wheel/subframe harmonics - you can tune the spring rate tramp with your damper
  • Proven fitment with installation support via messenger from people that have actually installed the item!
  • Can be installed with hand tools, however for speed we recommend using an air chisel and hacksaw when doing the diff bushes. Videos available 
  • Installation available in Melbourne, Victoria. We will need to remove the entire subframe and diff assembly.
