Wondering if going conservative or all the way, which set should I get, any suggestions?

 

I think 7/15mm is the perfect set up. I'm running that on my C4S. It lines up flush with the fenders.

 

Any idea if 7/15mm would be ok with c2s. I'm planning on changing the rears to 305's so I'm not sure if it extends beyond the fenders.

 

I have the same re same question, I know 15mm in the rear should work perfect for C4 due the wide body, but what's the suggestion for C2? 7-7mm or 7-15mm ?

 

I think 15mm is fine on the C2S. I think some have been running 18mm in the rear on C4S.

 

Will the extra 10mm (305's vs295's) extend beyond the fenders with 15 mm spacer in rear of c2s?

 

Running 7 / 15 on my c2s, looks terrific, not at all over the top.

 

Stock 295 in rear?. If so, will extra 10mm (305's) flare beyond fenders in your opinion.

 

Yep, stock 295's not sure what the difference would be given that the wider fenders of the 4s, but above comment by grey black is helpful

 

I originally put the OEM 5mm all around on my C2S. Wasn't enough. Changed the rears to 15mm 6 mo ago. I'm thrilled with how the wheel fills the wheel well and is now flush with the fender. Plus, I like the look of the C2S Carrera Classic wheel in the rear to the C4/S since it is more flat (and thus flush) than the latter with the spacers. Overall this gives the car the 'wide body look' without the wide body.
Left the 5's on the front since to go to 7 didn't make enough of a difference and more than 7 is not recommended.

 

Same question. Are u running 295's oem tires in rear? If so,in your opinion, would 15mm in rear with 305's extend outside the fenders. I'd love for anyone with c2s and 305's with spacers to comment. Thanks

 

I'm running 7 ,15 on OEM 295's, looks great just short of flush imo, would love to switch to 305's when tires are done.

 

I don't have my car yet, so I haven't been able to measure fender spacing with 15mm installed in the rear, but let's think about this logically. OEM Porsche Pirelli P Zero in 305/30ZR20 are 0.3" taller and has 0.9" additional section width. Without seeing it, I would guess a 15mm spacer on a C2S with 305 Pirellis might be a bit too much. Now a Pilot Super Sport might have a better shot at 0.2" taller and 0.7" wider in 305. PSS comes in a 305/25ZR20, but the specs aren't showing on Tire Rack. That could be an option as well.

 

I've got RSS 7/15mm black spacers & techart lower kit on my C4S cab looks & rides great

 

Here are a few Before and After pics pre any spacers, and now with 5mm Front and 15mm rear. 991 S with PDCC & Sports PASM so lowest stock model available.
