My wheels are of the Italian variety and am wondering if anyone has had problems with them at the track for DEs.
I'd hate to have to buy new wheels.

Thanks,
Daniel

The MM have two flaws, they are soft and heavy, so they add to the unsprung weight of the car, and if you hit some of the curbing you may bend them.

As far as a real flaw, like they fall apart at 100 mile an hour, well nothing like that exsist. OEM wheels are the way to go.....

Renn 951

I've run them on the track several times with street tires and haven't had any problems. With RA-1 tires I go with phone dial or pie plate OEM wheels.

IMHO, if you're trying to minimize your DE expenses you should be OK with them, but when you're ready to get some R compound tires you should bite the bullet and get some stronger, lighter wheels to go with them.

Pick up a set of 16" D-90's. They're light and strong. You can get a set with minor curb rash cheap.

Actually, there are a handful of cases where this HAS happened, but not that often. It can also happen with factory wheels but that's even less likly to happen.
I'll second Renn 951's comment that they should be OK for a novice on street tires but once you go to R-compounds it's time to upgrade. The D-90s can often be found at a reasonable price but IMHO there's a better choice, the "flat disk" wheels are a strong, lightweight, well-made, forged wheel and nobody wants them because they aren't "flashy" enough. These wheels were what Porsche used replaced the Fuchs wheels as the "top of the line" for the offset change in 1987. They can often be found dirt cheap (especially when "cosmetically challenged") and they are one of the best wheels (quality wise) available in late offset. Wheel enhancements used to sell 'em for ~$250/set for snow tire use!

Dave,
Which are the 'Flat Disk' wheels?

dave120

I think he's talking about the sewer lids that you see on some 928s. I'm too lazy to go find a picture of them right now though

dave120

ok, maybe I'm not too lazy

Sewer lids! Makes me want to run right out and buy a set! These are the Design 90s, right?

No, flat discs are not D90s. Here are better pics:

Good timing Sefang! I just went and stole this from there and uploaded it!

Smaller holes than D-90s.

Jfrahm

No, those are forged "flat disk" wheels. They come in 928 and 944 offsets, I do not know if the 928 fronts will fit OK on a 944 as they would be 12mm or so farther inboard. They are somewhat unloved but quite strong and reasonably light (19-20 lbs per wheel.)

Nice pics on Wheel Enhancement's site:

When you see the club sport and flat disc next to each other you can see how they are the same basic wheel but with a different vent hole.

The D90 is similar to the club sport but cast. Good wheels.

I actually like those wheels, I wish I would have bought a set of those instead of my PD's.

Sewer lids? That's awesome. I always disliked those wheels and now I have an apropos name for them. Thanks!

dave120

I didn't make up that name for them. I remember seeing someone on here refer to them before as sewer lids so that's what I call them now.
