Default Special on RH 3.6 Wheels



We were running short of components to build the RH 3.6 wheel, so we ordered up 3 pallets of centers, outer lips, and inner barrels from Germany. We can now build these in nearly any 5x130 Porsche fitment, and we will be selling them at way below the retail price while supplies last! Expect a 5-7 day build time once the order is placed, giving us adequate time to spec, build, seal, and test.

Typical fitment on a 993 C2 is 18x8 ET52, 18x10 ET54. Price will be $3749 + shipping (wheels only). A slightly more aggressive fitment for the front is an 18x8.5 ET45 (pictured below).

For a C2S or C4S, you can run either an 18x8 ET52 or 18x8.5 ET45 on the front, and then an 18x10 ET40 or 18x11 ET40 on the rear. Going to an 18x11 in the rear will be $3799 + shipping (wheels only).

The standard center finish is silver, but they are available in black for $400 extra.

These do take factory lugs and center caps, but we also have many aftermarket options available. If you would like a complete package with tires, please contact me by PM or at 888-488-2028 (Cameron @ ext 255) for fitment and pricing.

I believe those are offsets for widebodies. The regular 993's take a 65mm rear offset.

Yes, you are correct about the factory offset of ET65. With these particular wheels, however, we've found that running the ET54 fills up the fenderwell and looks much better. There happens to be a bit of room to play with back there, and we've been selling this fitment on 993s for years with no issues.

On the 993 Turbo and Widebody we actually run an 18x10 or 18x11 with an offset of ET40, believe it or not.

That's correct...you can get 10"ET52 (and even 11"ET52) with fender rolling on NB rears; for the fronts 8.5"ET45 works fine and 9"ET40 will work with minor fender rolling. For widebodies, my rear is 11"ET28 with roller fenders.

More pics, doctock or GMP?

Meaning with that offset the wheels are "out" a bit more and look fuller/fatter in the wheelwell?

The centers are cast, while the inner barrels and outer lips are spun. While not technically "forged", spinning aluminum does generally produce a lighter and stronger product than casting. Because of this, most of the weight in the 3.6 wheel is in the center, which is indeed cast. That said, 23lbs for an 18x8 and 25 lbs for an 18x10 is not that heavy, especially for a multi-piece wheel.

Exactly. An ET of 65 is the factory being safe and conservative with fitment. Pushing the wheels out more with a lower offset of ET54 gives the rear wheels a more aggressive look and also widens the track slightly.

The green C2 in the pictures above has an 18x10 ET54 in the back. If you compare where it sits to the factory setup, you will see what we mean
