Wow..The concave looks tight on the front....Maybe I need to trade out the 8.5" for the 9.5" > wonder if they will go for it? Any rubbing? Flush with fender? One more ? Coilovers or lowering springs?

Just got back from a DE event at Putnam Park in Indiana. It is a great track. 1.8 miles, 10 turns and lots of run off room. The car and it's new wheels/tires worked great. Among all the Porsches the Z4M attracted a lot of attention, all of it positive. Everyone seems to love the M Coupe, including me!!!

Since this is not my main track toy, I was not too concerned about the adjustibility of the suspension, thus I'm just using shims to get the desired camber up front. ![]() |

Guess I'll stick to my original plan and keep the 8.5" up front. In hand plus I know they wont rub. I think my -1.6' camber would rub with the 9.5 up front.

That's probably a good plan.
I just can't see running that much camber on anything other than a dedicated track car.

Plus I dont want to have to wax another set of front wheels. Man, two coats of wax took some time, even with the wheels on my lap.

^ This may be one of those chicken & the egg things.
The more neg camber that is dialed in; the bigger the spacer.

I just noticed that he is using shims to get more negitive camber... it makes sense now why he has to run a larger spacer. When dialing in more camber with a camber plate the the strut moves with the wheel thereby keeping the spacing between the strut and wheel the same. When using shims like I have in the past and dialing in more negitive camber the shims cause the wheel to move closer to the strut. I think I should be fine with a 5mm spacer and -2.5

Wheels really look great. Seems like a very good wheel choice for our cars.

Thanks for the compliments guys. I love these wheels. They are light, strong, great looking, and functional. I've been pretty busy at work lately, so I haven't had a chance to take more picture. I'll try to get more pics up soon.
F360C, you are definitely going to be ok without spacers if you dial in your camber using a camber plate, and -2.5 is more than sufficient to clear the fenders. Both of my other friends who are running 18x9.5 +35 up front are running without spacers. Both are using 255/35/18 tires up front. With my current setup, my wheels can actually barely clear the strut body with a 5mm spacer, but I wanted a bit extra space just to be safe. |

Both cars look great. I have 8.5x18 front and 9.5x18 rear ARC 8's in hyperblack on my 06 Z4M roadster. I'm totally pleased with them and would recommend them to anyone who likes the look they offer. Best bang for the buck I found.

I really like the added camber with the 9.5" wheels up front. Steering response and turn-in became super sharp with the slightly stretched sidewalls. Understeer is virtually nonexistent with this setup.
There are a few downsides to this setup. Stretched sidewalls will make the ride become a bit harsher, and the added camber will tend to make tires tramline a bit more than normal, but I'm used to driving cars lots of camber, so it is no big deal with me. Also, tires may wear out faster on the inside if you drive mostly on the freeway in a straight line and not doing much cornering. But since I run 0 toe up front, and take my car on canyon runs and trackdays, that should not be much of a concern for me. |
