I was wondering if someone could provide the stock offsets for C4S wheels, also Turbo wheels. I was also wondering if I were to go aftermarket what type of offsets woul I need? Thanks

 

Contact one of our sponsors like Wheel Enhancements or do a search.

Also read the numbers by your valve stem - the smaller number is the width of your rim and the bigger number is the offset.

C2 vs c4 off sets the fronts are the same the rears are approx 16mm different.

 

I've been trying to find out for a while as well.

 

It is in the Owners Manual, on the back specification section. I will look it up tonight and post if you would like.

 

I looked at the rears (as I am most concerned about those) and they appear to be 19x11 and ET51.

I am looking at a set of BBS RS-GT's from tirerack and they seem to be ET60. Isn't that offset to high for the rears? Is that not a Narrowbody(996TT) offset? When you search for a C2S they give the ssame wheels with the same offset.

 

The OEM C4 Carerra S rear wheel is 11 x 19 et 51 - OEM 997TT wheel is the same size (althought there is a narrowbody version with et 67). If you use the BBS wheel with et 60 you'll need spacers to push the wheel out.

 

That is what I figured. I am trying to avoid spacers at all costs, I am just wondering as i thought that Tirerack would only include direct fit wheels (ie-no spacer) on a search for your specified vehicle. There is no mention of having to run a spacer on the website. Thanks

 

WOuld these fitments be ideal for my C4S?

F: 19x8.5
Offset: 53mm Bolt Pattern: 5-130

R:19x11
Offset: 60mm Bolt Pattern: 5-130
Rear would include a 12mm spacer


Thanks in advance

 

I don't know what you mean by "ideal" - I guess ideal would be the same as OEM...however the fitments you show above for the front would give 2mm less inner clearance and the outer position would extend an extra 10mm. For the rear without the spacer, inner clearance would be 9mm less and the outer postion would retract by 9mm. The 12mm spacer only moves everything out 3mm more than OEM - you might want to consider a 17mm spacer for the rear. Call the guys at Wheel Enhancement and see what they suggest. Good luck.

 

It appears to me the wheels in consideration would:

front at et 53 - increase inner clearance by 4 mm from the stock et of 57
rear at et 60 - decrease inner clearance by 9mm without spacers but with 12mm spacer it would increase inner clearance by 3mm from the stock et of 51

 

After further research BBS suggests using a 15mm in the rear although I don't see why 12mm wouldn't work.

 

I go 17mm for even better look
