i figured zcps were the same as oem 19s. idk ill just run spacers if needed. thanks for the info.

 

i just found this:

http://www.1010tires.com/WheelOffsetCalculator.asp

 

i also just saw this:

ZCP Wheels are 19" x 9.5" rear with a 27mm offset and 19" x 8" for the front with a 47mm offset.

not 100% sure which one is correct.

 

HOLD UP GUYS... those are not CSL wheels. They are the Comp Coupe... 19x8.

The original post was for the CSL wheels, of which the fronts are 19x8.5... different width. I've yet to see a set of fronts remotely close to $400.

 

i am pretty sure he wanted the ZCP wheels, not necessarily the CSL.

 

Strange... I just checked with my BMW parts supplier... both part numbers come up as 19x8.... something is off, b/c the Euro CSL wheels are 19x8.5.

 

i am also pretty sure that the euro CSL wheels are made by bbs and possibly forged.

 

Here's the thing... CSL rear wheels have the same part# as the ZCP rear wheels, which we know are cast. So, unless the CSL wheels are forged fronts and cast rears, it's not likely that the fronts are forged. Ideally, I'd want CSL-sized forged wheels...

 

well since you mention forged csl's, i should mention that the company that produces the CSL reps IS in fact coming out with CSL forged reps, AND Morr alloys already has then out. ive been in contact with them. they were doing group buys for 1750 and they are an aggressive offset for the e46 m3, thats another wheel we could look at imola. plus they are 19.5 lbs front and 20.8 lbs in the rear. i believe they are 19X8 front and 19X9.5 in back also.

 

contrary to what was stated on the ZCP package from bmw, the CSL's or ZCP's are NOT forged.

 

i stand corrected then.

if i was to change the OEM 19's i would ideally want at least 8.5" up front. this way i can at least run 245 with some room or even 255's. 275's are probably gonna be a bit too much up front.

as far as morr alloys, their site is essentially non existant. but for a $150 more than stock zcp wheels i would say that it is probably worth getting forged. let me know how this develops. i will also have to buy some winter wheels but will most likely get some cheapies when the time comes...

 

i run 245s up front on my oem 19s perfectly fine, so i dont think you need to worry about getting 8.5 inches up front. the forged csl reps are hopefully gonna be good stuff or else the ZCP wheels are fine. im almost gonna say the ZCP are better just bc they are OEM and made by BBS you know theyre good.

 

i just found some other somewhat related info:

If I had to do it again, I'd spend the extra $700 and get the real ZCP wheels.

I weighed my CSL reps, and despite the manufacturer claiming that they weigh about 25lbs, they actually weigh about 31lbs. The weight saving alone (close to 40lbs of unsprung weight since real ZCP wheels weigh about 22lbs per corner; that's like shaving 80~120lbs of weight on the car) is worth the extra $700. I was able to feel the acceleration became slower and the car didn't handle as well as before. I'm switching to the BBS RGR's. I''ll probably just keep the CSL reps and throw them on the car when I'm ready to sell the car/trade in. The reps so cheap even brand new that it's just not worth it to sell them used.

Edit: mine are the velocity motoring replica's
