Wheels Fuchs vs Cup II

Fuchs even in 15x7 are not allowed due to weight and cost.
Even so 15's work great on our cars since they reduce the gearing a bit, lower the overall ride height by 1/2 inch and most important combine a cheap available wheel with smaller/cheaper tire. We might see some enhanced performace on the right 17 tire/wheel package, but it will increase the costs for a small gain. Even so straight line acceleration will suffer with larger diameter wheels and a heavier combo.
Oh.. you can get 15x7 fuchs to fit on a late offset 944. However you need the right tire, camber and ride height to make it not look jacked up. That 89 did not get it right and is a bit jacked up.

ou may not have understood the post ... you may want to read it agaian .. the statement was if the weights are similar .. and no one said the performance would not be different .. the performance will be far superior with bigger wheels and less sidewall .... we take the same car on the track you and your 15s with a 3 inch side wall and me with a 17s with a 1.5 inch side wall you will get eaten alive in the corners, you will have body roll due to sidewall flex .
race cars don't go to big wheels and O rings for looks ...

Now reduced sidewall flex is a good thing, but you can in face reduce sidewall flex by changeing tires. Some have much stiffer sidewalls. Plus if you really want to get into it deep sidewall flex is a part of the suspension and you need balance these factors.
There in fact many factors that come in play, but big heavy wheels will reduce the feel of the car. I can even tell the differece been old tires and new tires an how much rubber is on them.

AND, you can't run those 16X7 Fuchs with those small 205 tires unless you buy 951 Fuchs. Fuchs with the 911 part#'s won't fit over the turbo calipers, hence the 951-styled Fuchs wheels that carry a premium on the used wheel market for both the 944 and 911 guys wanting bigger brakes but keeping the classic looks.

1) Orignal Poster is an 8Valve NA.. no worries about TURBOs here. So, conceivably,the 911 and 951 part #d fuchs would work. I wouldn't do it on a late offset car because you will be sacrificing tire size to make it work properly.
2) For appearance, Cup IIs. They really "modernize" the car and look great. You will also find more than 1 brand/size to work. 7.5 fronts, 9 rears. Run 225-245 front, 255-275 rear.
3) I have some 17's on my car. Came that way. Fine on street, but will be looking for some 15"s (phone dials) for AX. Lighter, smaller overall diameter (225-50) will liven up the car.

My S2 came with after-market cup II's. I really like the look but after driving a 944 with 16's (and a very nice suspension set up) I was totally hooked and sold the 17's. I now have some phone dials on and running the usual 205 F / 225 R. I felt the 17's made the car feel "dead and heavy" and it tram-lined a fair bit. I was a bit unnerved at first by the sidewall flex and thought I had made a mistake changing over but now I'm used to it I love the nice early feedback and that great "chauckable" feeling the car now has.

The tires I have now ( p/o installed ) I think are the wrong size 215/60/15 with a stock 15x 7 phone dial.
The only other question will there be issues with the lug nuts with the diff offsets ??

I also went from 15" (phonies) to 17" (Boxster) back to 15" (phonies and cookies for the track.
All other issues aside, when you're really using a car on-track, and you're buying a new set of track tires every year (or more often), the 15"s pay big dividends. You can get RA1s, Falkens, NT01s, and others often at half of what the big boys pay. It helps that the same tire(s) are used on Spec Miata.

We should be talking moment of inertia instead of weights of the wheel/tire. It's important to keep the weight down, but also keeping the weight closer to the axis of rotation. I'm on board with the "run the smallest wheel you can fit over your brakes" philosophy. If you're going to big brakes, get a wheel that will fit.
Another factor that I want to draw attention back to is tire availability. Wide tires for small diameter wheels are really hard to find. Anything wider than a 245 for a 16" rim can be tough to find.

Sorry to bring up an old topic but Im still considering doing the fuchs.... What is the size Fuch wheel to get that WILL fit without any rubbing or any rolling fender mods ? Also would the Cookie Cutters fit ?
