Here is topic I am very intersted in and have been able to get little solid information. I have copied and pasted posts and comments from various threads to start this topic fresh with more focus.

My understanding is that a RWD conversion costs about $2,000 including all new Porsche parts and labor. It involves removing the front drive components and addding ABS/PSM wheel sensors from any RWD 996. This will convert to RWD, keep all ABS/PSM functions and NO dashboard lights. What you get is a RWD 996TT. You also lose 150lb.

What you do not get is a full GT2 conversion. It is expensive since the GT2 uses different suspention arms, factory cilovers, carbon brakes, etc... (depends on what call a FULL conversion I guess).

If you want a GT2 conversion, you should probably just buy a GT2. If you want RWD 996TT with all PSM functions intact, the plan above seems to work perfectly fine from what i undestand. BTW it is my understamding that GT3 arms allow for better adjustment.

The only thing I am not sure about, is the effectiveness of the stock 996TT LSD in RWD only mode. Is it a weak point? It has been suggested that a 60/40 LSD would do a better job. What' parts are required? and what is the cost for something like this? ...and is it really required from a performance standpint?

This is a topic I have looked at for some time and welcome comments on the LSD or any other topic reagrding this particular plan. It has a lot of positives in my mind, less weight, a more direct steering feel, and about 7% more HP/TQ from removing the parasitic FWD components.

As an afterthought... will the stock tranny be subjected to unusual wear (from no longer having the FWD components to drive?

That's a lot questions, but I'm sure collectively we'll come up with more if this thread gets the attention I'm hoping it deserves.

 

The 996 turbo doesn't come with LSD. You have to install one if you convert to rear wheel drive.

 

Whats the point as we were disagreeing in the other thread the car and its set-up are meant for AWD you can not convince me you know or anyone here knows more then Porsche themselves

 

Why bother arguing the point?

If a TT owner wants to have 5% more power to the ground and a overall lighter car...without having to deal with the cost of a GT2...or the GT2's focused, and very stiff track suspension that makes it extremely hard to control big horsepower...why does it matter?

You seem hell bent on convincing us we shouldn't modify our TT's the way we want. Why does what we do matter to you at all?

 

I vote we all go back to stock

That's classic.

 

I don't think the argument is that we KNOW more than Porsche. It is that we are willing to make some sacrifices (IE lower ride height for the resulting improvement handling). What do you care or know anyway? The M3 is a nice car (I used to have one for 3 years) but it is NO Porsche. The M3 seems nice until you drive a Porsche on winding mountain road or better yet a racetrack. Driven Back to back to back, the M3 walllows big time (especially the newest "track" option which actually comes with softer dampers and springs). About the only place an M3 is competetive is in drag racing and only against select current model Boxsters. Some people!

So.... the TT has no LSD?

What's the conversion cost?

 

i think the idea is on point, infact great. when you do go around to doing it i'd like to hear how it's goes. i also think it'd be alot of fun to drive.

 

Interesting...

 

I've thought about this off and on over the last couple of years.

I think Scott said it was around $2k in his last thread. I'd love to know how it goes and others' experience with it.

 

Any advice from the veterans? I'm hearing off line that the stock LSD will do fine...

BTW this is a fully reversible and is easily tested by simply removing the front driveshaft. The PSM will freak out, but it will be fine for a day or two of testing

 

Ari, there's no stock LSD. It's an open diff and I wouldn't go RWD without adding an LSD in the back. Take it easy when you take that front shaft off, the handling of the car might not be the same.

 

There is a stock LSD which if I'm not mistaken was only available as an option on the 2005 Turbo S's...

 

When my car spins it tires....it's both tires that are spinning.
