So rears stick out too much with 21 inch wheels and 20mm spacer. Will move the 18mm from the front to the rear and try 15mm in front.

 

so 15 in front looks OEM but at the edge. 18 in rear looks more aggressive but doesn't stick out too much like the 20mm did. I'm happy now. I now have a staggered look too.With "wider" wheels in the back.

 

Looks good!

I just bought a set of spacers as well (from ECS). Went with 15mm front and 18mm rears for my 2014 CTTS. Will post pics once installed.

 

Sounds like you found the right combo...and you could really see the difference of 2mm in the rear - that's like the width of a dime?

 

Yeah I didn't think it would be noticeable either but it is.

 

Im using F15 R20mm 20inch RS spyder with GTS wheel arch. Cayenne Diesel

 

What's the offset on the wheels before spacers?

How about pics of the 15mm and 18mm setup pls! Also, what did you fellows do about longer lugs? Would be great if you could post direct links here for the ecs part numbers. Tks!!!

 

15 front 18 rear
ECS offers kits with matching bolts
Nice black finish for the spacers
I have the 21 inch wheels first responder in this thread posted 20 inch wheels with 23 in rear.
Mine stick out about 2 mm because the fat 21 inch tire but it now looks staggered

Hello!
I have exactly the same Cayenne GTS and am looking for spacers. I like the way yours looks. But those measurements (18/23) come only from one brand, right?
H&R?
Have you had to buy longer screws? Measure? or are the spacers with screws for the dough?
Where did you buy them?
Thank you.

Federico.

 

Yes, mine were H&R and yes you definitely need the longer bolts - never install spacers without those!

They are easy to find, many shops sell them, or buy direct from H&R.

 

Hey, what size of lugs did you use for this setup?
