Hacker, those wheels you posted the ebay link to aren't the right offsets for a 928. The rears won't fit. You need the ones that have an offset of ET67 for the 11" rear. Buyer beware. There was a set that sold today on ebay for $1750 plus $188 shipping that was the right offset.

actually,
the 67 offsets won't fit either without a spacer(at least not with the 295 tires that typically are on them.) i have the same offset and size but the more attractive narrow 5 spoke (i believe they're called the carrera classics) on my 90 gt and i had to use a 12mm spacer to get them to fit. the 51 offset may fit without a spacer if you use a narrower tire (275 maybe.)

For all the great wheel choices available from other Porsche models and the aftermarket, I still feel that Porsche really struck a classic and timeless design with one 928 OEM wheel ......

"Caps"? It's an 81 so only one distributor cap.

Car runs fine, fired it up let it idle long enough to blow all of the coolant in the exhaust (FYI - drain the heads before pulling the exhaust manifolds off - otherwise a boat load of cooland goes down the pipes). Then drove it about 5 miles to my storage unit. It was 8PM and very cold in January, I did not have a timing belt tool, snow was coming and I had to move the car.

cfc928gt,
I didn't even look at the offsets - my bad.

shaaark89, the 67 offset on an 11" wheel should just fit in a 928 rear wheel well, at least with rolled lips. It is 1mm further out than my forged club sports that came with a 17mm spacer on my '89 GT. You just don't need/use the spacer. It also moves the inner wheel in by 15mm closer to the suspension on an '89 GT than if you had the stock 9" wheels with an offset of 60 and the 17mm spacer so it should fit there as well. I love the look of those wheels...

Garth, I'm with you on the CS wheels. I just wish they came in 17" or 18". That or someone would make a tire in 255/45 16, which would be a better fit and look better than the 245/45 16.

i have the wheels on my car and they don't fit without a spacer. the tires WILL rub on the control arm. theory is theory, real life is real life

Hmm. Well that is interesting Tom. It's a pretty finite calculation isn't it.

I'm shark sitting for a buddy who is a lurker here, his handle is kewl928owner. I just put these 18" chrome Sport Techno wheels on. The car is a '91 S4 in a dark Grey Metallic.

Tom, interesting about needing the spacer. Real life trumps theory every time! Looked good on paper but... What size spacer are you using? Any fitment issues with the outside rubbing using a spacer?

shaaark89

it's either a 12 or 13 mm spacer. with 295 tires there is barely room on the fender side and less than a finger width between the tire and control arm.

looking at the calculations i'm not sure i follow.
the new wheels would protrude an inch (25.4mm) more on the inside than the 9" club sports. take away the spacer and that adds 15mm more. add the difference in offset (7mm) and the new wheel should protrude 47.4 mm further inboard then the 9" clubsport with the spacer. leave the spacer in and it drops to 32.4 mm. use the 51 offset wheel without the spacer and it would be 31.4 mm. clear as mud?

Tom, whoa, I haven't even had anything to drink and you've got my head spinning. I used one of the offset calculators I found on the internet. I just went back to it and realize I forgot to add the 17mm for the spacer being gone to the inside protrusion. According to the calculator it shows the inside is moved in 32mm and the outside is moved out by 18mm. Okay on the outside since the spacer would be gone but 32mm + 17mm and you get the same as what you came up with...

Guys


I'm fitting a set of 996 twin turbo wheels on my GT next week, i'll take some pictures while i'm doing it and try and post them if anyones intrested.

Fronts are 8x18 ET50 225/40

Rear 11x18 ET45 295/30

Does anyone know what tyre pressures i should be running with these.


Stuart

shaaark89

i have these exact same wheels/tires on the 89 s4. i run pressures in the low 30s with them. the rear fenders will need some aggressive flaring to make them fit.

DANdeMAN

Just imagine these on the 928!!!
ATTENTION : pics are by Titanboy_24 more of is work HERE




Sorry images may not show........

I have run 295 on my S4 with very minimal flaring. I just rolled the inner lip, the profile of the fender is untouched..... Stock ride height..

Kibort runs 335 on his S4 with minor flaring.... No spacer..

I have since switched to 285 on all 4 corners..

HTH,
