Gen 3 Diff Upgrade?

[v10addiction]

Go to Unitrax or Taylor race, for sure.

They built the rear end in our world record Ballista among many others and we have never had a problem.

We also use them in our ACR-X's after the factory rears died.
Nothing compares to a full quaife.

Drag racing, road racing, street driving, the quaife is the answer.

As for the 3.55 gears, it comes down to where your using the car and your money.
More gear in the rear is for lower torque levels and more shifting.

Gear multiplication makes more power get to the wheels, but shifts come sooner and more often.
3.55 gears means less traction in all the low gears.

They higher the torque, the less gear needed and the bigger gap between shifts, but more importantly traction.

If you make big power, don't waste your time on gears, it will slow you down shifting and you will run the motor harder on the highway.

If your upgrading the rear end, most builders wont reuse your stock gears, so your most likely buying gears anyway.

Spend the extra money on a quaife, you wont regret it.

To put in simple terms, on a road coarse, you can shift in the corner with the quaife and most cases not lose traction.
Try that on your stock end, but let someone know beforehand, so they can film it for youtube.

A quaife gets in and out of corners faster.

Gen 4/5 cars have a simple version of a quaife, which is one of the main reasons they run so fast on the road coarse.

If your racing is limited to less than 140mph, you will see nothing from 5th and 6th gear anyway, even with 3.55 gears.
If you cruise more than anything, you will just be adding miles to your motor, and have to get the speedometer re-calibrated.

I could definitely be wrong, but I thought I read somewhere that the PCM/ECU pulled speed from the tone rings on the wheels, thus no speedo recalibration was needed...

The actual strength of the limited slip is what I can't stand. I haven't even had the car on track yet but even on the street on aggressive corners I feel like the car likes to boil the inside tire. I feel as if I'm having to really finesse the throttle and work the wheel more than I should need to. I feel as the diff is a bit unpredictable and with that it almost feels like the car wants to step out without warning.

This is exactly what I felt with the stock diff, and what I now don't feel with the Wavetrac I put in. You can literally feel the Wavetrac working back there, transferring power back and forth between the two rear tires as they approach their traction limits. Gives me enough time to back off a bit before being snakebitten (which I was with the stock diff).

I have no doubt that other aftermarket diffs will give you similar results. Can't imagine anyone has ever regretted upgrading from a stock Gen3.

I didn't notice this with my stock gear or certainly not with the upgraded Gen4 differential - your rear end may need an oil and sure-grip additive/supplement change. I have had several friends have what sounds like the problem you are having go away with a fluid change - or at least get better. But if you apply too much throttle on cold tires you will break loose - not a rear end problem but a cold tire problem. I considered a quaife when I got mine but after talking to a few folks, I decided to try the Gen4 upgrade instead. I have been pleased and the 3.55 gears have made it easier to drive not harder. Yes you do shift a bit more but once you get used to it, it really doesn't seem to be much different on the street than the 3.07 gears - but it pulls much harder and is easier, IMHO, to drive than the stock gearing was. Try to find someone near you who has a different setup and then make your decision. I have had what I thought were fast, powerful cars over the years but nothing compares to the sheer torque and power of a Viper. As I said before, the HPDE will open your eyes and make you a better driver. Give it some time.
