I'm thinking but need some help:

Pro:
1. Looks
2. EZ and inexpensive mod

Con (but un sure):
1. Quicker and More rear inside Tire ware?
2. Any wheel bearing or seal damage / leakage?
3. Any effect on the warrantee (incase something goes wrong with the added offset leverage?)
Warranty item wont be covered due to the spacer?
4. Any vibration or added noise?
5. Any rubbing if someone sits in the back seats?

Then the question:
A. What size should I order?
B. Why should I mess with a car that has be engineered for years and as of now running beautifully.
C. Will anyone except myself notice the mod?

any input would be helpful.

Thank you

 

Even 5mm as spec'd by Porsche (and included on many cars from the factory) are noticeable. I think since Porsche approves them for particular wheels, they'd be fine for the car and not affect warranty. I like them because they make the front calipers easier to clean.

And agree with NorthVan, below; I put them on for me - don't care about what anyone else thinks about it.

 

I have 7mm Front and 15mm Rear on my C2S, and I Hoyle imaging the same sizes will work on your 4S. I haven't seen any increased wear on my tires or other parts. As for anyone else noticing them, who cares? Do you drive your car for yourself? Or for others?

 

+1......and get that thing lowered with some CO's.......

I added the OEM 5mm spacers and they look great. I have 305s in the rear and the tires are flush with the body of the car.

 

+1. My 09 C4S came with the OEM 5mm spacers. I was originally annoyed at getting an option I wouldn't have ordered but now I love them. They are definitely noticeable.

 

I'm running 7mm f/15mm r on stock wheels on my CS2. I also went to 305s (RE-11s) on the rear from stock PS2s. The rears are flush with the fender lip. It doesn't matter to me if anyone notices.
