I am ordering a C4S with sport techno wheels
I have read that they are .5 inch wider than standard wheels and would like to optimize aggressive stance. Would 5mm spacers added to my configuration be enough?

 

Can't add them from the factory with the sport techno's because they are wider. Suppose you could still do it aftermarket though.

 

The rear Sport Techno wheels on a C4S have a different offset from the rear Sport Techno on a C2S. I'd wait until I saw the fitment before doing spacers. Porsche does not supply/allow spacers on the Sport Techno wheels. I know on my C2S I don't think spacers are needed but haven't seen a C4S with Sports Techno yet to see how much they fill the wheel wells.

 

I've only seen photos, but they looked pretty good in stock form. I have Sport Technos on order and am in no rush to get spacers until I live with the car a while.

 

I had the Sport Technos on my C4S- they needed spacers still... albeit slightly less aggressive ones that those who are using spacers with their classics on the C2S.

I went with 7mm front and rear as the shop I went to didnt have 10mm for the rear and 15mm was just a bit too wide.
