Hey Guys...
I know this is a topic that has been revisited countless times by some of the more seasoned guys, but I can't just seem to find the info that I need to make my purchase easier.
To put it simply - I have an 88 944 Turbo S with m030 suspension and I want to put 17 inch wheels on it.
I would appreciate it if somebody could supply me with the correct sizing, offsets and all other information I would need for 17 inch wheels that will just 'bolt on' to my car without the need for spacers etc.
I'd like to put wheels from a newer porsche and any wheels that would just bolt on would be greatly appreciated.
Thanks,
Michael

You want something close to 65mm front and 60mm rear offsets, depending on how wide of tires you are trying to run and if you want some sort of flush look, like Robby.
How wide for the rims again depends on how wide you want to run the tires. I think some have run nearly 315mm in the rear. I run 275mm in rear and they fit no sweat, and my rear wheels are only a 52mm offset.
So first decide how fat you want to go on rubber.

I ordered some .125" spacers for mine- they were $30 for a set of 4, including postage- from another Rennlist poster. I'm only planning to use them on the rear. I know that 1/8" isn't much, but I'm hoping not to have to run longer bolts, or different lug nuts, and I understand that 1/4" is about as far as the stock one's can be pushed- I like my titanium or aluminum (depending on who you ask) lug nuts
I'm hoping the 1/8" will push the rears out just enough to make a slightly noticeable difference...

Yeah, IceShark's right on with the stock offsets (65/60m). However, there aren't ANY stock 17" Porsche wheels that carry these offsets. If you go with 52.3mm offset wheels, then you would need to go down to a narrower 7" wheel with 205mm tire to prevent rubbing on the front fender.
So means your choices are really 3-piece aftermarket wheels. Here are some links:
My favorites has got to be the Simmons OM wheels:
Since they're Aussie wheels, you can probably find local distributors for better pricing than from the U.S. with shipping.
Any way you go, I recommend a set of 17x9 (70mm offset) front and 17x10 (65mm offset) rear. This will place the outside edge about 5mm outward from your stock wheels with most of the extra width on the inside. Then you can use 255/275mm tires or even 275/315mm if you roll the fenders.

Single data points don't make for good conclusions, but I've been running 993 cup rims on my lowered S with no problems. 17x7 and 17x9 with 225/45 fronts and 255/40 rears. Have run a bunch of street miles and one track day last week - semi-pro driver friend took it out to demo to a customer, too. If he didn't find a problem, they should do well for my purposes. The rolled fender lips of the S do seem to help.
Danno's tech note reminds me I should have the alignment checked this winter if I'm going to run these more.

I can't understand why I had no problems with my 17" 993 wheels I purchased used at $1K for my track tires for my 88 944ts. They fit perfect in every way and I can put 275's all around if I wanted. I think they are the best looking, they are light weight, and they are Porsche.

Thanks for reproducing that Danno. I needed that info.
![Smilie](https://rennlist.com/forums/images/smilies/smile.gif)
Hmm, going to non-S rims of the same width will have the front wheel sit 1/2" outwards and the rear 1/3" further out. So yes, they can be used. But you're limited to 7.5/9" widths which is fine since the Porsche 17" wheels appear most popular in that size.
I'm really talking about optimizing offsets to get maximum rim-widths and tires under the fenders for maximum performance like GT-style racing. I've got a set of 17x11/12" BBS racing wheels coming and the trick to getting them to fit is to put most of the extra width on the inside where there's more room (increase offset).

Hey Danno,
Resurrecting an old thread, but seen your posts in quite a few different forums regarding 951 wheel sizes and offsets.
Wanted your thoughts on the bulletin you and so many have posted.
In another thread you said that as width increases the offset needs to increase and that is why as the 951 wheel size increased so did the offset. Now I am wondering as I am about to buy some 17 for my 89 Turbo, how come the Porsche bulletin has front 17x7 et 65 but front 17x8 et 52? Sounds strange that they would add an inch and then push it out an additional 13mm. Would this even fit under the fender?
I am currently looking at 17x7.5 et 65 and 17x9 et 55, but these can be custom built so I was trying to figure out if I went with 17x7.5 or 17x8 what right offset would be to keep the wheels aesthetically pleasing but still under the fender. This is just a weekend car so no track time or else I would use those ultra wide setups that you have recommended.
Your insight would be much appreciated.

Oh, hopefully he is ok. But he seemed like the expert on wheels and offset.
maybe some else bumps into this and can confirm if 8x17 et 55 will work on a 1988 Turbo S front without issue. Seems like so many mixed answers out here.
Thanks!

@JustinL
Is your answer from first hand experience?
Would you change the offset, assuming that you didn’t need or want wider tires? This would be more cosmetic to make the wheels pushed out but still under the fender.
Is 9.5x17 et 55 too conservative for the rear?
For tires I would likely run 235/45 front and 255/40 rear.
Thoughts?
Thanks in advance.

You can run a clubsport rear on the front, which sticks out more and has less inside clearance. You can pop one of your rear wheels onto the front to get a feel for the fit. Use the 1010tires offset calculator to get an idea where your prospective wheels will line up.
I must admit that I haven't had stock springs for a long time, so I have more flexibility with wheels. But I've also tried a lot of combinations including 10" ET55 fronts that can be made to fit with the right springs and camber plates. I think my current wheels are very close to what you are hoping to run. I don't have the exact measurements, but I think they are close. I run a bigger set of tires with 255 front and 275 rear. Your planned tires will have a bit of stretch to the sidewall, where as mine have a bit of bulge. Mine is the silver car and I have quite a bit of camber as it spends a lot of time at the track (when it's not on stands though).
