I am considering a set of 17' wheels for my 951 but I'm not sure if the fronts will work with that offset. The car they came off had bilstein coil overs instead of the m030 struts so the seller is not sure they will fit stock suspension...

I was going to try to run a 225/45 tire up front since I already have a new set, but can buy new tires if needed since 9" is stretching that size some....

Thanks...

Should fit, I have an 88 951S and had 17" et 55's that fit. You might need a small spacer.

17x9" Fronts though...?

KaiKai951S

oh crap, didt see that. Car is at the shop but I can ask my mechanic to pull one of my rears and try it up front? Im actually curious muself. I always wanted those up front and 10's in back

That would be awesome if you could... My 951 wants these fikse wheels... Just have to make sure the fronts will clear...

Thanks again!

Ok according to the rims tire size comparer guide going from a 16x7 et 60 to 17x9 et56 only adds 6mm to the wheel well. Back spacing goes from 6.3" to 7.2"....

Anybody?

I've read that max fitment for fronts is 18x9 et 52 but according to this guide they should fit....

17X9 ET 55 fits M030 no problem on mine. I used a square set of 996 rear twist wheels for years.

Oh, Ok so I should be able to squeeze by with et 56....
Thanks

Yep, I run 17x9 ET55's too and they fit no problem.

brandon19761

Sweet!! Do you think there is one more mm of clearance left so I could still get away with 56et??

docwyte

Wouldn't think 1mm would be a problem.

I had 9"et60s rub the M030 spring.

Camber setting will also have some affect on whl/spring clearance.

brandon19761

hmmm. Thanks.

docwyte

True, I run -3 degrees camber...

Oddjob

The more neg, the less clearance there will be. I probably had about -2.0 to -2.5 when I tested 9s on the front of my stock 89T, and they rubbed pretty hard. But you dont need a lot of clearance, as there is not huge flex in the wheel or strut. 1/4" should be fine, which is why et55 works, and et60 does not. Also, due to the strut angle, a larger diameter wheel will have very slightly more clearance, so a 17" may give you another mm or so vs a 16".
