Do 18x8.5 and 18x12 Work Mesh Wheels with Michelin Pilot Sports in 235/40/18 and 315/30/18 sizes fit on my 99?

Thank you.

BR....totally depends on the offset. But, I don't think you can get the 12" rear on regardless of offset. My advice would be to keep searching. You could get away with the 12" rear on a wide body 996 (C4S or TT) but not on the narrow body.

I have to agree with Dell on this one. (Man, I really do hate it when that happens!)

For example, if you got a 12" wheel with a 65mm offset, the wheel would extend 1" farther to the OUTSIDE and 1" farther to the INSIDE (in the wheel well) compared to a 10" wheel with a 65mm offset. It would most certainly rub somewhere, either inside or outside, or both.

LVDell

Let's say that the offset if 65 in the rear as a starting point. If you want to know how far out it will stick it would be like adding a 25MM spacer to the rear and that is just for outwards movement. This doesn't even cover the inside movement. I think it's save to say that you need to stick to 11" or less on the rear and with the proper offset.

yes.... i have 11's right now... i think i need fender rolls........luckily i didn't lower it yet.....it would be rub city for me....

newport996

11's are the max....if you have the right offsets, 11's will work without rolling the fenders......

Porsche_Smile

so how do i know if i need to roll or not? just drop it and find out? it looks real close.... but i can't tell for sure...

newport996

iForged wont fit right....they are too wide on the rears....I think you need to roll....but the correct offset would not need to be rolled....iForged is known for that.....they are probably about 5-10mm too agressive on the offset....

Porsche_Smile

nuts... that's probably why i got such a good deal on it..... it does look real aggressive though... how much is it to roll anyways?

LVDell

smile.....do you know what your offset is? that will help figure out if you need to roll or not. But if you have those iForged wheels then you are screwed on that front. Never understood that company (and the people that sell em) and why they won't divulge their offsets. No matter what they say their offset is WRONG and they just keep selling em and people keep buying em. What a shame.

newport996

Yeah Dell,
correct...nice wheels, but why not sell an OPTION to have them -10mm in the rear? It seems we get like a post a month about the rear iForged wheels....

Porsche_Smile

you know what dell... i do not know the offset... once i get a chance i'll take some pics... but the front looks fine..... it's the rear that's iffy to me...

LVDell

arrogance maybe? too stubborn to admit a mistake in the offset calculation? who knows. Regardless, it's total B.S. and something that amazes me that poeple keep buying em.

LVDell

yeah, it's the damn rear with those iForged wheels. Fronts are fine but rear are all wrong.

newport996

Yeah, people buy them because they are assured they are the correct size for a 996...so they think why question the experts? Once they are on, they think..hmmm....not sure, but they say they are right and we disbelieve.....When I was searching for wheels, I looked ONLY at offets....I knew I wanted something like the GT3 18's fit, but in 19s....so 11 rears, about a 63-67 offset....fronts were easier, there are only a few front sizes for all 996's....but getting the correct info meant LOTS of research and asking LOTS of questions.....for some its easier to look at a abook, pick a wheel and pay someone....and HOPE its what they want.
