Thanks guys for checking out this new wheel line up.

 

What is largest possible ET in 8", 8.5" and 9x18" sizes?

 

If you can send me an email to matt@gmpperformance.com I can email you a PDF file so you can take some measurements on your car. One thing I've learned when trying to build custom wheels for the older Porsche's is that not every car is the same. So if you could email me I will email it back over to you for you to fill out and then I can send it to the engineer for them to figure out what's the most agressive fitment we can build. I have built 3.6 wheels in the past though with an 8.5 front and 10 and 11 rears.

 

If you cannot get us to a 60+ ET, you won't find any customers in the 928 community that's why we're asking. I'll send you an email and relay the information.

 

That's understandable, but with the 928 crowd you are going to gain a lot more interest if you post a possible et65 or greater.

Resizing your images wouldn't hurt either. I'm on a 22" wide-screen and still had to scroll left / right to see everything.

 

Anything is possible with these guys and I don't think what your asking is a stretch either because just like our RH3.6 wheels which we are limited to only using the lips and inner barrels to determine the offset as all the wheel centers are pretty much the same, we are about to achieve a 18x8.5 ET59 front and an 18x9 ET65 rear. When building custom wheels we can not onl adjust the barrels and lips by the half inch we can machine the center disc to just about any specification.

 

ok then mine might be bigger then because I definitely don't have to scroll side to side.

I will see what I can do.

 

nice wheels and i like how the bolt holes line up with the wheel spokes,
some other HI Performance wheels seem to have the stud holes drilled as an afterthought

 

We really need 8" ET60, 8.5" ET67 and 9" ET74 which has proven virtually impossible to make for almost all manufacturers.

 

Well like I said before send me an email so i can send you our fitment guide form, fill it out and send it back to me and I will get back to you with what we can do.

 

That's not a very customer centric attitude IMHO.

Okay guys, Here's what he wants us to fill out.

PDF attached.

 

What no urine sample required also?

 

So someone needs to fill that out for 8x18, 8.5x18, 9x18, 9.5x18, 10x18, 10.5x18, 11x18, 11.5x18, and 12x18

In every offset between et65 - et75

I'll get right on that......

 

Hacker,
you need to turn your resolution up ALOT.

I am on a 18" widescreen and I can see the entire thing with ease.
If your eyes are that bad, maybe you should get glasses!

Or maybe we should all adjust our font to size 5 to make it that much more interesting for you

 

The images were bigger this morning. Just sayin'.
