Will these Wheels fit?

[CJ_Boxster]

Im in the middle of buying some used Porsche Turbo 2's from a widebody 996 TwinTurbo... Will these wheels fit my boxster?

They are the wheels pictured in the image below.

I'm betting you'll need spacers. Do you know the offsets of these wheels?

[CJ_Boxster]

Yeah i was told i'll probably need something like 13mm spacers but not 100% on that info yet. I dont have the offset info on the wheels...

Maybe someone here has that information.

They are the Factory Turbo II wheels from a 996TT widebody.

ok what i found out so far is the size but not the offset

Fronts are 8 x 18
Rears are 11 x 18

[lucky_topher]

11" wide!

i had those on my camaro with 335 tires

here's a good page:

Boxster:
Can use most wheels from the 996 with spacers in the rear. 40mm-65mm et front and 40-50mm et rear (Stock 18x10 is 47mm) the 18x10et 65mm 996 wheel will require a 15mm spacer to clear the shock.
Most extreme is the Techart 18x10.5 et 42mm wheel for the rear. Use zip ties for the parking brake cable. 285/30/18 tire is about the largest you can use.

Can use 19' from 987

Most extreme fit 20x9 et50mm and 20x10 et 60mm(15mm spacer) with 245/30/20 and 285/20/20

20x9et 50mm and 20x10et 60mm below




996:
On the 99-01 cars you can use up to 11" wide rears with an offset of 52mm. The factory 997 wheel in 19x11 offset 67mm will need a small spacer in the rear with some tires. The 2002 and up cars do not have this issue as the track was slightly widened. GT3 is 18x11 offset 63mm.

Theres a chance they could also be 10x18 TT wheels, Someone on Renntech with a boxster has the 10x18s with 13mm spacers with out problems, even says he has room to spare. Lets hope the rears are 10x18 and not 11x18!

They won't work... the 986 can't fit 11" rears... a 996 can, but a 986 can't even with spacers...

[Cloudsurfer]

No way, offset is fine, wheel is simply too wide.

18x11's will fit but you have use spacers and roll your fenders

[easyc]

and roll your fenders... thats the magic words there... but even then you wont be able to jam that much bigger tire under there.

[Wingnut2u]

I have 10.5 with 275's on my box and I would not want to go any wider than that, unless you want the 4x4 look with your tires sticking out past the wheel well. It looks good on my Hummer but not on a Box imho

[boxs2000]

If they are the original ones from a Turbo, they are 18x11's. They can fit with a spacer and lots of fender rolling. Also you will have to stretch the tire to keep clearance. Two other things to keep in mind if you do by some miracle fit those bad boys on your car. Added weight of a much wider tire and understeer.

[CJ_Boxster]

Ah thanks guys.

What Ill do is clean up the rears and see if anyone with a C2 riding on 18 x 10 Hollow Spoke Turbo II's wants to trade up for my 18 x 11 Hollow Spoke Rear wheels... So long as there rear set come with P-Zeros with 80%+ tread left.


Here is some info I gotten from the seller:
18 x 8 ET50 Fronts

18 x 11 ET46 Rears


Whats the ET stand for?

[easyc]

ET is offset... the turbo's offset rear is similar to ours, the C2's isn't... Front ET should be self explanatory... you need a 15+mm spacer. To the best of my knowledge, the Turbo II's did not come in 18x10 hollow spokes... only the turbo I's did... and those with a 993 offset... which I have no idea what that ET is

[RandallNeighbour]

I have 5mm on the fronts and 25mm on the back.

What I have noticed is that when my wheels are out of balance, it seems to feel more pronounced with spacers. It's like they "magnify" the problem in some way.

Should you choose a set of rims that require big spacers (more than 7mm) keep this in mind. It would be sad to pay a small fortune for cool wheels that require spacers and then experience wheel and body shake that's impossible to get rid of for any length of time and not be able to remove the required spacers.
