Hi guys, I'm going to look/buy some turbo twist rims tomorrow morning. I need to know if theses will fit. They are 7x17 205/55/ZR17 in front and 8.5x17 255/50/ZR17 in the back. I've being looking for data on offsets, calculates and so forth online to help me out. I looked at the wheel tread 3-4 times on here. I Know flosho has them on his 931 which is different then my 87 924S with a late offset. I talk to the guys dad on the phone, he didn't know anything about the wheels, he measure them to be 7.5x17 & 9x17, but I think he's measuring the rubber, not the rim. He didn't know the offsets, so I'll look tomorrow to see if they are right. I believe that turbos twist that are 7x17 & 8.5x17 have offsets of 55 in front and 50 in back. Anyone out there offhand knows about the fitment? Thanks guys

The 931 and 924S have the same offset requirements. A 924S is not considered "late offset", its simply early offset with a narrow body. Standard offset for the 924S is 52et so you should be just fine regarding offset, however, I would be a little concerned with the inside spacing. Why not drive the 924S there and mount them up before you buy them?

BTW, white 924S' rock. Nice car.

Thanks Nein for the info. I would drive my S over there if I could, it's in storage and snowed in a driveway 100yrds and about 6-8in of snow. I tried getting it out about a week ago, went 20ft and started spinning, there's no weight in the back with 1/4 of a tank of fuel.

So 52et is a good offset, that's good to know. So if flosho has them on his 931, then "theoretically" with a little fender rolling I should be able to make them work... fingers crossed...

As for the white 924's.... I agree, I think they look the best in white

Jayzzzz4, they should fit, but you WILL have to massage the fenders in the rear a bit. I have the exact same size tires. I guess it would also depend on the amount of negative camber in the rear and if you have the rear lowered, but they will fit.

I haven't lowed it, so I think it's at factory settings. I guess the only thing is that I have some KYB struts in back that seem a little on the soft side, but I can always buy stiffer ones. Thanks for your input.

Well, looked at the wheels today, I didn't buy them because the back wheels are 17X9 and the tires are 10"wide. The offset is 55et. Flosho, how much room do you have in back? Think 9's are too big?

9 inch rims or 9 inch tires? I have 8" D90s and they are very close to rubbing without rolled fenders. I don't know the inside clearance, but I would be really surprised if you could fit 9s on the back of a narrow body. I have 9" rims with ~10" wide tires on the 941, and they barely fit. FWIW.

The rims say 17X9 on the inside, but measuring with a ruler on top, they are 10"(sidewall to sidewall). So you say it's a no go? Your 941 has a wider body and they bearly fit.... Mmmm This could be a good excuse to go GT

Why use a ruler, divide 255 mm by 25.4 mm/in = 10 inches?

The front tires and wheels are a perfect fit on all 4 corners.

Depending on the tires and type of wheels I may be interested in the rears.

Well, I don't know the name brand offhand, but the back tires need to be replaced. I can't remember exactly, but i would say they are around 40-30% tread left which is fine for me, cause I only put on 1000-1500 miles a year. So if you want the backs for rubber, they aren't really worth it. But if you want the rims, I'll be willing to buy them a little bit more. I'm just a little worried about not finding two more wheels with out paying an arm or a leg for them.

You can't go wrong on those rims. Very sexy looking on 24's. I would keep mine, but I'm selling mine due to the fact that I can go wider, so I went with the even sexier rims (the 18x8 and 18x11 2002 911 Turbo rims)
