Hi all,

I'm interested in adding a rear wheel spacer to my '88 Turbo S, so that the stock Club Sport wheels sit just a little more flush with the fenders.

I'm looking at a 21mm Porsche wheel spacer part number 996-361-621-00, which includes a set of lug bolts. I'm also looking at the older 21mm Porsche wheel spacer part number 477-501-701, which fits older 944s and does not have a set of lug bolts. This begs a few questions:

1) Will 477-501-701 fit late offset 944s, including MO30 cars?
2) If so, are the car's existing lug bolts long enough to accommodate 477-501-701 or should they be replaced?
3) Are there any fitment issues with 996-361-621-00, and are they a better option because they have lug bolts installed?

1. Yes

2. No, you need to install longer 65 or 72mm studs

3. No, there's a difference between bolts and studs. There are no threads in the hub for bolts. You need to pound out the old studs install new ones. Easy way to do it is to remove the parking-brake cable. The hole where the cables goes in can be used to remove the old studs and install the new ones. Count on about 30-45min per side.

Thanks JacRyann. If I want to preserve the original wheel studs, it sounds like I need to use something like H&R's 32mm DRM wheel spacers, which bolt to the hub using the existing studs, and the wheel is bolted to the DRM studs.

Would 32mm (approx. 1.26") push the wheels out too far and cause fender rubbing? The fenders on a Turbo S are rolled at the factory, but I don't know if there's enough room to accommodate 32mm spacers on the stock 9Jx16 wheel.

Just mock up some crude 32mm spacers using washers for a test fitment on jack stands. You'll need to test BOTH sides, as they can be slightly different.

Thanks Johnathon. If anyone else has run 32mm spacers with stock Club Sport wheels on a Turbo S, I'd love to hear about it.

I ran 20 then 15 mm spacers with the rear 9" CS and both worked fine. I wouldn't go larger than 20.

32MM sounds like way too much.

I must say that I am not a big fan of wheel spacers in general. They cause extra leverage on the wheel bearings, which will not last as long. Plus, large spacers in front can screw up the scrub radius/steering.

But, small spacers (<10MM) to clear large brake calipers/springs aren't too bad.

Just my $0.02.
