What are the proper offsets/lowest offsets I can run with this setup? I've read that there are ranges between 40-58 but I was wondering how a ET34 would work on a 17x10-10.5 on the back. I dont want to roll any fenders or touch the body at all!!! I dont mind cambering in a little or what not but absolutely wont touch the body. Thanks in advance for any input or suggestions!

Does anyone have pics of some lower offset wheels on 964's?

10ET34 - will need some serious lip rolling and fender flaring.

10ET40

10ET44 to 10ET46 would be my recommendation.

As for 10.5, I have no idea. Use the tool in the link below to recalculate based on a 10ET44-46.

You are going to get different opinions on this, so check yourself ...

Diameter is irrelevant btw, so you didnt need to tell us it was 17".

For the front, here is an 8ET50 ...

Clayton, IMO you are going to have to roll your fenders regardless...the 10.5" wheel will require a tire broad enough that you'll have to massage it into the well.

As much camber as you can get will just be a start; a lot of this, of course, depends on how low your car is to begin with. Lower = more massaging.

I'm not an expert by any stretch but 10.5 w 285's is probably too much judging from all the posts here and at PP. 10.5's will stretch the tire a bit more than 10's. you start to run into the oil line among other things. 10 's w 285 30 18s are a lot in a 964, but it should be more than enough depending on your goals.

btw, sml above has pushed it about as far as most folks, check his links. personally i've been ok w 10's and 285's w ET44. like he says, that's probably the sweet spot , 44ish.

sml

btw ... other variable is spring rates and ride height. keep in mind.

might be able to do 10.5.

you could do it this way with some stretch ... but might limit how low you go ..





but dont stretch this far ... ;P

Consideration of the ride quality also needs to be taken into account.

c didy

yeah. stretch doesn't do it for me. plus it limits the ability of the sidewall to roll and there goes a chunk of your cornering capability.

Thats exactly the stance I was looking for! Not sure what those cars have as far as widths and offsets or fender modifications or not. I was hoping to put a 245/40 on the back and an 205/45 on the front. Dont really want to go with any less rubber than that. Also, I have just fitted KW V1's. I dont mind a little camber but I do want to enjoy driving the car too...I want a balance of drivability and stance=)

seem like you want extra wide wheels, but then you want skinny tyres?
did you read the threads which I posted above?
my tires are 265/23 and 235/40.
plenty of room in the front.
plenty of room in the rear with about a 10ET46

i still think you should understand and do your calcs using your car and current wheels/tyres ...

got any pictures of what you've got now?

This is how it sits right now.

My stance with 18x10 ET 65(-15 spacer=50) (265/35) and 18x8 ET 47 (225/40) with wheels that look similar to yours (but 18 vice 17):

https://rennlist.com/forums/8671643-post9.html

For 17's the original Porsche fitment was 255/40 rear and 225/45 or 225/50 front as per http://www.porsche.com/uk/accessorie...-03-01-classic
but as long as rolling diameter of tires is near factory (for speedo accuracy) then it really shouldn't matter what size you put on - as long as they fit inside the wheel wells.

this is a nice photo of 10ET50.

with our photos, keep in mind:

a) that as you drop the car lower, the wheel will arc inwards and provide more clearance

b) that as you change the camber from neutral to -2 deg (which was the max neg camber that I could get with stock suspension) there is about 5-10mm movement of the top corner of the wheel/tyre near the guard.

with the 10ET50, i would be interested to hear how much clearance there is between the inside tyre edge and the suspension arm. must be getting very close.

sml

from my link above, this photo below is the 10ET40 with about neutral camber.

with the -2 deg camber, plus combined with the arc as the car is lowered, the 10ET40 gets very close to fitting without any lip rolling or fender flaring. but you may not be happy with the tyre life on the -2 camber depending on your car use.

Thanks for all the input guys. I dont mind the camber issue. If the rest of the alignment is dead on camber wont make a huge difference, toe is what really burns the tires up, although camber does play a small factor. Either way, I appreciate the input. I'm going to do some test fitments!
