TRE carefully disassembles all components, hot tanks all components and performs a Magnaflux inspection before doing detail and machine work.
Before the final product is assembled, everything is beautifully cleaned and proper clearances are ensured. Pictured is the viscous transfer case, where the Wavetrac front differential is housed.
All assembled and ready to get bashed into a concrete wall!
One of the biggest changes to the car has been the drivetrain. Originally keeping the AYC/ACD system, the car was upgraded to an Evo X rear SAYC differential as well as an Evo X hydraulic pump to control everything. Not being able to leave well enough alone and looking for savings to both weight and complexity, we switch to a completely mechanical setup. An Evo VIII rear differential and a viscous transfer case were sourced and then sent the magicians at TRE Transmission, also known as Team Rip.
We choose a 1.0 way configuration for the rear differential to allow freedom of wheel speed side-to-side under deceleration. The goal is to have the car turn in quite easily, relying on suspension, aero and alignment for stability. An added sight glass also confirms proper oil level.
Our MAX-LOCK rear differential prepped for service with aluminum solid mount bushings.Jon Ripple at TRE performed his MAX-LOCK service by adding additional clutch plates to the rear differential while also converting it to 1-way operation. An oil sight glass was added as well as a heavy duty side cover made of CR-4030 that controls preload on the carrier bearings preventing axial and radial play of the ring gear, which in my terms, keeps expensive stuff from breaking. The transfer case also received Jon’s special touch receiving gear detail work to the ring and pinion, a slick neodymium trash magnet upgrade and machining of the case to accept larger M10 bolts. While he was in there, a Wavetrac torque biasing front differential was also installed. The Wavetrac was chosen due to it’s smooth, helical differential design along with the ability to lock in cases where wheel speed differential overcomes the torque bias ratio, which can be an issue with OEM and other aftermarket helical differential designs.
