18" vs. 17" Wheels

I like the Cup 2s They really look nice on the car. The 17s are pretty rough riding with the m030/HD setup for a DD especially since I installed the RS engine mounts. Though I I heard that there is an 18" version of the Cup 2s....
Oh yeah, and I remember reading a website of some guy in England I believe that documented all his 993 mods. After doing alot of suspension work, he decided to try the 17s and ended up liking the handling better.

The 18 inch Cup II aftermarket versions are an enigma, a myth. I looked until blue in the face for a set back in the day; Germany market mostly. The Audi’s of day UrS4, UrS6 were often seen around Germany shod with the 18” Cup I’s knock-off’s. I owned a UrS6 wagon (RS2 mod's) at the time with the popular 993tt caliper/rotor transplant. If I recall RH wheel of Germany was the manufacture.
+1 the 18" Cup II wheels look great on a lowered 993 coupe.

Interesting topic. Thanks for posting. I have considered 18" & lowering car with m030 or m033 as well. I was unaware of the rubbing issue. My p-car mechanic did advise me to stick with 17's & not change the suspension. I will ask him again on the reasons. However, this posting has me a little concerned with the rubbing issue.

18" wheels and tires do not equal "rubbing"
many variables:
from tire size, to wheel offset, to ride height, to tire manufacturer
all can play a role
as for "limiting plates"... Are we thinking of 964s?
and... I think you are confusing "looking cool" with performance, Alex.

My 95 C2 came with 18's hollow twists ... no rubbing at all ... running HD's + M033 at ROW height. I have been told by several that the ride is more "civilized" with the 17's. I doubt if I will change ... I've gotten used to these.

I fixed that for you.
But two out of two cars inspected with the correct wheels did exhibit rubbing. I guess there are a few out there that don't and as I mentioned above, it depends on the make/model of tire at times. Its enough to remove the rubberized coating, but not the primer, so it isn't excessive. In my case, no thanks!
No...993s. Its been a while, but I believe it was Bill Verburg that mentioned that plates can be installed within the rack to limit travel. This after I asked if there were adjustable steering stops on a 993 shortly after acquiring it. BTW, that plate looks identical on the 964 and 993 on the on-line parts catalog.
As for looks, the Porsche crowd is almost as bad as the motorcycle crowd when it comes to bling. Much to the dismay of the motorcycle crowd, I didn't drink their cool-aid either. Yes, I'm aware about the trade-offs...performance vs ride.

Ultimately it should come down to individual taste and desire.
17's will not be as harsh a ride due to additional sidewall
in general, 17s will be lighter, although there are some very light 18s available
18s CAN cause rubbing, but with the right offset, there can be no problems, i.e. the MY02s are a very popular (and light weight) choice and do not rub, even on a lowered car.
Looks is purely subjective and up to the individual consumer.
Ride quality will also be subjective and what the individual is willing to put up with. Road quality will also play a factor.
I had Cup IIs and actually love the way they look. I happen to like the MY02s a little better, and got a set of them which are on the car now. Ride got a little harsher, but I primarily drive this car on smooth freeways, and I like the feel of them. I will say that it is still a better ride than my former 911SC that I set up as more of a track car. (learned my lesson, I won't do that to a street car again!)
For the OP, purchase the car (assuming you like it and the PPI checks out)
it is easy to borrow some 18s and see how you like them.

I bought my car used ... I'm 4th owner ... as best I could discover, either the first owner took delivery or added 18 inch Technology Design turbo twists. 2nd owner was a dealer, 3rd owner said they were on when he bought it. Here are the part numbers (from an old note I had written to check against Bill Verburg's Wheel fitment chart).
18 x 8 993.362.136.00- 19.95 lb ET 52
18 x 10 993.362.140.01 - 23.36 lb ET 65
I believe 18 inch Technology Design wheels were an option on NB C2 in 1997.
I hope this helps ...

Not saying I know everything but I'll try to help with a few facts:
18" wheels do not equal rubbing, period.
Same can be said for 17" wheels.
The tire's rolling diameter should remain very close to the same, regardless of wheel size.
18" wheels were offered on 993s (after '95)
As I said, a number of other factors contribute to rubbing, including alignment specs
If you are happy with your wheels, great. Cup IIs are an excellent wheel in the 993, IMO. All a matter of choice and personal preference, sometimes trade-offs from a ride comfort vs. handling perf perspective.
Not everyone agrees. I think that makes life interesting.
YMMV

So....how did those rubbed off strips on the inner fender well made by the tire's tread edge when at full lock (I would assume) occur? Nasty squirrels with a palate for undercoating?
I'm not saying it is a big deal. It obviously isn't to those who don't care, but it might be to those who do.
There were 18s fitted, but according to the Porsche parts catalog, there are also different fenders available based on the M codes.

Wait... hey, you made a funny!
Nice to see there is a sense of humor in there
Have a great day, Alex
