I just bought some new OEM ZCP/CSL wheels and thought I would post up some pics of the difference and a review. The old were stock 18's with stock sized Bridgestone Potenzas, new wheels are 19's with Michelin PS2s 235/35 front 265/30 rear.

Weight difference (wheels only):

OEM 18 made by Ronell
18x8 24.8 lbs
18x9 27.0 lbs

OEM ZCP made by BBS Germany
19x8 23.0 lbs
19x9.5 24.1 lbs

Impressions: I was really worried about the ride being much harsher on 19's compared to the 18's, fortunately that was not the case. Honestly I could not tell a difference. However, the weight loss on 4 corners is an added bonus in terms of acceleration, braking, and steering response. I'm glad I went the OEM route instead of the CSL reps. I have KW var 2 coilovers on the way along with RE spacers (15mm front/10mm rear), these will give a nice drop and a filled wheel well look.

my god csl wheels look sooooo much better than the 18s, or even the 19s for that matter.

I really love the stock wheels, but for whatever reason those csl's make the car!!! Nice!

if you don't mind, how much did you pay for those oem csl's?

Thanks for the compliments guys, I can't say enough about the wheels, should have bought them sooner.

if you don't mind, how much did you pay for those oem csl's?

PM sent.

If you think they look good in silver, you should see them in black.

BTW, nice car.

If you don't mind me asking, where did you get the CSL wheels, and how much?

I love that green btw.
