You're awfully close - those aren't stock 993 TT wheels, they are stock 993 T wheels. T as in Targa, which did come with 16 wheels from the factory...Not hollow spoke, but very nice looking!

Ok some more information on the 16" 993 (Targa) wheels, all with 70mm offsets:

Description I found for the 993 stock setup:
"New design of pressure cast aluminum Cup wheels 7.0J x 16"ø front and 9.0J X 16"ø rear. Tires 205/55ZR16"ø front and 245/45ZR16"ø rear."

The wheels I bought (yesterday) are a set of 4 9.0J x 16" to which I had mounted/balanced A032R 245/45ZR16.

The part # on the wheels: 993.362.118.01 (anyone know a site where you can enter the part # and get the description?)

Made in 1995.

Also this set of characters appears on the wheel: GK-AIS:7mq0.4wa (anyone know what this is or means?).

I'll be putting the wheels on again (with rear spacers) soon to take some pics to post and to take a test drive on them before going to the track. Danno, I have the stock M030 suspension.

Danno, to answer your other questions:

1) Yes I use a pair of 38mm H&R DRM spacers on the rears and the wheel well fills out nicely. Don't need spacers on the front at all.

2) Yes I have front coilovers, which gives me the extra room to the inside for 9" front wheels. If my car was not an "S" my 9" fronts they would not work. I rolled the car back and forth with the new (to me) wheels/tires and no rub.

Fonck

Ok Danno you were right. The front 70mm offset wheels don't work at all with my '88 Turbo S coilovers...major rubbing action. So...I added longer front wheel studs and about 10mm of washer-type spacers to the fronts and it works great. I tried 28mm H&R DRM bolt-on spacers on the fronts but the wheels rub the front fenders under extreme moves. Note that the wheels rubbed slightly even though I run 2.5% negative camber on the front. I might've gotten away with a 21mm H&R bolt-on spacer with my negative camber, but it wouldn't have looked balanced with the rear wheel inset from the fender. On the rears, I left the original studs and added a pair of 38mm H&R DRM spacers on the rears and the wheel fills out the fenders nicely. I run 1.8% negative camber on the rears.

Washers? Eek! I would look into getting a real 10mm spacer for the thing, you can get pretty much any size you want. Seems like doing washers individually for each wheel like that for almost 1/2" could lead to issues.

Matt Sheppard

Could you try using the 8mm spacer that you can get aftermarket (also came stock on some 912's). I've been able to use these spacers w/ steel lug nuts on normal stock studs with no problems. With your longer studs, it sould be a happy marriage, maybe even able to use alloy nuts, not that you are saving weight at this point w/ all the spacers and such.

The whole washer thing would give me the creeps.

Fonck

let me be clearer...the spacers on the front (I don't have the exact size but are somewhere around 10mm) are washer-type only in the sense that they are different from my bolt-on H&R spacers in the rear. They are traditional spacers, not washers. :-)
