My 60-130 definitely suffered, as I can see the wheel spin in my logs. If I had to do it over again, I would do a LSD, no matter what kind of driving you do. This will give you the ability to put the MOST power down (if not all), if you are modded. A lack of a LSD will have less of an effect if you are stock or lightly modded.

Similar outcome to my experience. With my old 3076 tial turbos and around 700+whp (open diff) the car was spinning endlessly, even when tracking straight on highway. Not sure how it works for others but traction not existent.

With an LSD it was a different story so If you do not have it, you do not know what you are missing.

I'm thinking of trying RWD and really don't want to disassemble my OE front axles with only 27K miles on them. I want to fully remove them and the diff, drive shaft to get full effect. The light nimble steering is more important than the added power to me as that's what I miss most in from my C2. Oh, the RWD tail weighted bias throttle steer too, big time. Anyone know of available options, used axles available, stubs, etc?

Thanks for offers of newly produced stubs but I'm not looking to spend mega cash on this project. I have 5 other vehicles that are currently registered and insured demanding part of my pay checks.

Here is the difference in the TT and GT2/3/cup stub axles. You can see the toothed ring is much larger on the GT version....

Thanks, I have read hundreds of posts on AWD conversions, some say GT2/3 will work, other say no, no one says exactly why they don't fit. I found out yesterday before your post it's the speed sensor gear size.
