... did you end up changing the rear diff to an LSD variant? If so, which one? If not, how does it drive?

From my reading on here, my understanding is that the rear diff on a Turbo 996 is NOT LSD, which probably makes putting down the power after a RWD conversion pretty tough even with suspension changes. So I'm curious what those of you that run track events have done to remedy this. I really like the idea of removing 70lbs of weight off the car, and I'm very used to driving high-powered RWD cars around the track (albeit not mid-engined ones), but I can't imagine it being very effective on a 996TT without an LSD in the rear. But maybe I'm wrong due to so much weight being over the rear tires?

Any info would be appreciated.

 

I was told point blank not to do the RWD conversion unless doing the limited slip, even more so if you have power added to the car

there are a ton of threads on here about people that did it w/o LSD and never had problems as well.

 

The car still inherently has great traction, if you have a lot of elevation changes at your tracks, you will notice when you crest a hill, the wheel that's lightest will spin and leave a black mark and smoke trail down the track. Not that serious, and only happens in certain turns when you can really put the power down but can't keep both wheels weighted.

However it's not any more dangerous because removing 55 or so lbs from the front of the vehicle will make the front end significantly lighter inducing significantly more mid-corner push.

I have an LSD now, but have not went back to RWD yet, and if I do I'm not taking out the front diff, I'll just remove the input shaft and front axles as I think most of the gain in top end is drag related. You can still shed 20lbs and keep some ballast in the front.
