I cut the front axles right behind the abs ring then tapered them in on a lathe to reduce weight some more. Dropped all the front drive components. Then put a GT2 spec alignment on her. fun fun fun to drive after that.. I found it safe to drive with the open diff then with the motorsports unit I have now. As I mentioned in an earlier post that joetwint did a great DIY.

 

Tim,

Let me guess, if I don't reinstall the front axles after removing everything else, basically my abs won't work right?

 

your wheels will come off. the axle, stub shaft after you cut it down holds the hub into the wheel bearing. the hub and the stub squeeze the wheel bearing between them.

 

I have never seen a stock 996tt with a transaxle that had LSD. Porsche used PSM and PTS instead. This also goes for the 2005 model. I believe the GT2 and GT3 have LSD. I have never seen LSD as a factory upgrade for the 996tt.

 

My 2001 996TT has an open differential - I checked at the dealer to make sure. I also have disconnected the front driveshaft and am running RWD at the moment. The main reason for doing so was to try and get some dyno numbers on my car with the recent upgrades.

However, I went on holidays and when I got back winter reared it's ugly head. I have Pirelli snow tires on the car and was really worried about how it would handle the snow of winter in RWD only. Much to my surprise it's been a blast. The grip has been good and on the odd occasion when I do break traction the PSM corrects things. I am amazed at how good these cars are.

I have purchased a Wavetrac Differential ( http://www.wavetrac.net/ ) and plan to have it installed with a new clutch this month. At that time I will have the AWD re-installed. I can't wait to see how much better it will be after the return to AWD.

 

Wow! this is an old thread! Shows how far we've come as a group in terms of what's possible, effective, etc... since March 2006 when I posted this thread, all the questions had no real answers Just speculation

ABS and PSM continue to work just fine with a RWD conversion. I ran my car on and off with the front driveshaft removed for several years until the engine made enough torque where AWD really helps acceleration (as opposed to massive wheel spin in RWD).

This is a very worthwhile conversion with or without an LSD until you get past K24s IMO. After that, there is so much torque that you need AWD to get power down consistently. As is, the car spins in AWD through 1st and 2nd and can get pretty crossed up. Especially on cold mornings when the tire are still cold.

 

thanks! exactly what I was looking for.

 

any tiptronics go RWD? I know BHT was RWD.

Thanks!

 

No one is as dumb as me Ben. You WILL total your car and hurt yourself or someone else if you go RWD.

 

I'm getting ready to dyno my car on a 2WD dyno and from what I'm reading, there aren't any issues with doing this by disconnecting the DS.

The plan is to disconnect the DS, dyno the car, re-connect the DS right after.

Can someone confirm I won't hurt anything?

Thanks, TK

 

Yes disconnect DS and remove, dyno and reconnect, that easy.

 

Bumping this back up- Im thinking of doing this but would like some feedback from tip guys

 

I have a 2001 turbo tiptronic with about 550 whp on an awd dyno.

I had my mechanic take out the central shaft..this takes only a couple minutes and disconnects the front driveshaft. I still have all the components (weight), but its RWD.

I have driven with it for a week or two now, and I really haven't noticed much of a difference. Car was not realigned, but is set to euro gt2 specs, lowered 2"

I do lose traction when it rains much easier now. Also, there is a bit more oversteer.

Thanks man, thats what I wanted to know. Surprising its not much different to drive around. I can't stand when you are in a hard hard turn and the front tires are trying to pull you where they are aiming. I would like to be able to toss the rear out a little bit without that bite.

Any issues with PSM? I think ill try my best to do the shaft removal this weekend. ANyone have any tips on how to do this? Specifically what tools are needed
