Default Finished RWD Conversion

I finished the RWD conversion that Capt. Obvious wrote up as a DIY a while back. First impressions are that I'm too damn tired to go for a long drive - but a turn around the block did confirm that everything's working as expected.

The steering feels loads lighter, but I can't tell if that's due to the conversion or due to me being accustomed to driving my 'Vette for the past few days.

It is remarkable how much weight is lost - about 80 lbs, if I remember Capt. Obvious's post.

Unexpected benefit: If you're an international drug smuggler, you will be able to fit quite a bit of product in the center tunnel once the drive shaft and differential are gone.

Looking forward to some long drives to get used to the feel...

To avoid if possible: Dropping the differential on your face. Ow.

Important safety tip: check. Thanks for that heads-up! Thanks for the international drug-smuggling tip, too. It's always good to learn a new trade.

Regardless of the weight reduction, the car should feel quicker because the HP loss through the AWD system is removed. Well done.

Agreed. The Getrag unit is likely fairly efficient, but not as efficient as NOTHING.

I dont get the point of this. Why not just buy a C2? The AWD is a great benefit of the C4 / C4S so why change it?

Why replace the IMS bearing with a different design? Why use different exhaust tips than stock?

I bought my 996 because it was ALMOST exactly what I wanted - manual transmission, aero kit, full suspension upgrades, etc. The only thing I wasn't crazy about was the AWD - so I "fixed" it.

Nice to hear about another C4 to C2 convert. After your nap tell us how your Porsche handles after losing some weight and adding some 'feel'.

The lighter steering feeling isn't just you, I noticed the same thing as well. Glad my thread about the conversion was helpful.

Also, another benefit of the AWD->RWD conversion is the C4 chassis is quite a bit stiffer than the C2 chassis, which is why they use a C4 chassis for the GT models.

^^^ It's not because it's wider?

Well he just has a standard C4 not a C4S, which is not any wider than a C2 for the 996, just like a GT3 is the standard width body-wise for the 996 era

Correct. My C4 is not a wide-body.

Whether or not the front wheels are driven does not affect PSM operation.

The '99 C4 has PSM, but PSM is in no way freaked out that the front drive has been removed.
