What are your camber settings now Zippy? Do you get much push or power understeer, which can be hard to distinguish between?
I almost had it almost completely nuetral untill I went and tried to lose weight with RWD and messed it all up.
You can always put 20-30 lbs of ballast in the front. Try to lose it in the back as well and improve the balance of the car at the same time. That should negate the push of the LSD by providing more front traction.

I was responding to your question on PSM there Tom. That is time the PSM costs me respectively. And consistent with most.
As far as RWD, I lost at least 1 sec at Barber because of it, and had I been able to put a good lap together without traffic maybe narrowed that down to .5 or so. But it was SOOOOOOO much harder. And not at all because of oversteer, but pushing all over the place.
Of course my setup wasnt near what yours is, but I'm not willing to try LSD under the suspicion that it could increase push. I need more bite on the front end without having to drift around the track to get it rotated. When I get it down, my car will be sickeningly fast.

offer still stands to drive my car at Sebring this weekend, Daytona next month or Sebring jan and feb. after that we will try to come to your sandbox if you dont want to play in ours.
would be nice to see what time you turn in my car. have you driven a Cup car around RA?? the Cups I have been with (996) have faster cornering and exit speed with slower straight line speed than my car so lap times come out about even on a big coarse.

Sorry to bump a really really old thread lol, but I plan on doing this in the immediate future and was wondering if anyone had the pics that joetwint uploaded as I no longer see that link as working. I'm a pictures type of guy and wanted to see them to confirm I'm doing it correctly.

Bumping an old thread. I converted my TT to RWD and love the driving characteristics. I took the conversion a step further and made my own axle delete stubs. They weigh half as much as the broken down CV axle stubs, allow for the stock axles to be swapped back in whenever you want to go back to AWD and there's no need to disassemble the CV joints.

how did you accomplish that? it is beyond my pay grade no doubt, but i'd like to be able to keep my original axles if at all possible!
ya never know, it could snow out here lol

i am nearing the completion of the rwd insofar as i/m running rwd only have all the parts and already run the wavetrac etc. just need to stub the axles! have the gt3 parts etc.

thx for that info. will give it some serious consideration. i am determined to complete ( properly ) my rwd conversion and get rid of that infernal hanging front diff and fix the front end geometry once... and for all 
in the meantime rwd with tbd lsd is a gas. heavy front end or not! it's insane

your stub looks good! Too many irons in the fire for me right now, had to put the machinist on hold that I had contracted to do my work. I don't think Ti would work for the speed sensor rotors as it is nonferrous. You need iron or steel to create and interrupt a readable magnetic field to get the signal.
Are your take off stubs available? I need something to reference and don't particularly want to take my car down this time of year.

My OE stubs are spoken for, sorry.

For a highily modified 996tt (+600whp)
Is there any difference in power from AWD to RWD for a manual car??? Can anyone give me the logical answer behind this ??
Advantage and disadvantages ????

throttle steering becomes possible where it really isn't before owing to the nanny aids. also, if one were to go all out and rely upon only their skill and the positive aspects of a properly setup rwd turbo, then one might be able to replicate the type of performance zwart is able to achieve with his gmg setup turbo gt3 up pikes peak. ponder that, and it all becomes clear, the potential advantages.

RWD will have more power to the wheels and properly converted will have less drag. The front drive absorbs power and even with the front driveshaft removed it's still sucking some up. How much of a difference this makes is open to debate but I'm told it's noticeable.

I have some measured times for 0-60, 0-100 30-130 and 60-130 when I went AWD with tune and exhaust to RWD with the same... my car is FBO now so my measurements are over a year old... the difference in 60-130 mph was quite a bit.. I think it went from 8.3 secs at that stage to 7.8-7.9 secs or so on the same road same slope same temps or so

So it's much better to do conversion yeah ?
Any side effect of this step ?? What would be the difference % in whp??
Like to hear more inputs from the guys who did it over here
