rear end
I noticed on sweeping curves during Auto-X that the inside tire would break loose with almost any amount of throttle. in a straight line, both tires would spin more or less equally. I've only seen the issue on long sweeping turns. I was running with the car in competition mode.
so...... I have previous experience with truetracs (from 4x4 days) and now reading tech on them indicates that they are nearly optimum in this type of situation. they have a very smooth application of torque to the slower turning wheel to help the car go faster through and when coming out of corners. I decided while adding the truetrac that I would add the LPW cover, primarily for the additional fluid capacity but also for the added strength to the bearing caps and improve the case rigidity. it turns out that GM only sells the factory bushings installed in the covers and cases. this means that I would need to get some aftermarket bushings. I went with the softest ones I could find, the BMR street version.
I don't think I really need them, but I decided to go with some stronger axles to remove any doubt. I picked up a set of the 1000hp versions from G-force when they were on sale.
I don't have the equipment to set up the gear on the carrier, so I took it to a rear end shop in Baytown.
it has made a HUGE difference in the way the car drives. the bushings are quite stiff. the trans is now very clunky between shifts. I've had to relearn how to drive the car "again". now it rarely clunks, but is very sensitive to trans temp. I can't beat on it until it gets just below 180F on the gauge.
as far as traction is concerned, it no longer spins the inside tire on long sweepers. the back end will kick out if too much throttle is applied. power is now getting applied to the pavement, it is up to me to be spot on with the go pedal.
