im no expert but from what i went thru with figuring my setup it seems wider than 315 requires exact measurements and no room for error. i have seen 335 on here but its a major tight fit
with your ductwork issues maybe a 40 et in 12" and 315 rubber in 18 would help

Can you give me some more specifics on why you would not choose 19s? Thanks!

Attachment 188807These HRE P44SC look great as well. Not sure about fitment.

I guess I'm old fashioned. I prefer plane old silver or a variation there of.

looks like a forgestar cf10

Attachment 188810Not bad looking. Still think I like the P44SC better.

i didn't like the stability of them at speed in canyon style driving, and i think the abs/psm might also be affected, though i'm less sure of that. plus they rubbed the wheel liner at hard turns. just not a fan of 19's on these cars. beyond looks.

Pretty close. Looks like the P44SC 10 spoke is organized in sets of 2 with larger spacing between them. The Forgestar CF10 appears equally spaced for all 10 spokes.

In what way - loose in the turns?

BBS CH-R looks great too.

I do like the 2004 GT2 rims, but they are difficult to find and a good price. They are 18s.

But these are great too. Perhaps I could work with these in 18s.

Not Bad. Still liking the P44SC though.

dont forget to consider the weights of the wheels also. look at the oz racing allegrettas

not "loose", but rather a greater propensity for instability. that's the best way i can describe 19's on my car. not so, 18's. you have to remember the tire/wheel combos really affect the abs/psm sensitvity on these cars. bottom line is, porsche knows why they chose 18's for the 96t gt2's, even if i don't.
