Hey all,

I've seen two colors for the 18" wheels. One is a dark smoky color and the other is more silver. Anyone know the difference? I heard the dark ones are what ended up on the production units. Is this true?

Thanks,
BoB

Yes, that's true.

With EDC on Comfort you can fly over them.

I posted my measurements here (post #10): http://www.m3post.com/forums/showthread.php?t=127032

Pretty much the only "performance" part on the M3 I am worried about is the brakes....sure 14" rotors sound good....but single piston brakes....come on thats weak...my 20 year old Porsche has 12" 4 piston brembos at EVERY corner...& that thing STOPS...never faded them at the track, even with worn pads!

The number of pistons has no bearing on fade resistance. Pad material and cooling are more important, along with the rotor size. Most tests say the brakes on the E92 are pretty good. Not Porsche quality, but fine unless you track a lot.

Of course lighter weight benefits handling.

Bigger rotors and calipers weigh more than smaller rotors and calipers.

Please provide support for your assertion that a BBK weighs less than the stock setup.

Two piece rotor with aluminum hat weighs less than one piece cast rotor. Four piston StopTech or Brembo ST40/F40 caliper weight less than stock caliper. Look up the respective weights of both on the web and you will see significant savings in weight by going with a similar sized BBK.

Yep, weights of stock vs. Brembo and Stoptech here (post #3): http://www.m3post.com/forums/showthread.php?t=150944

i'd think that it'd be dangerous in comfort because that would allow more travel and would be more likely to bottom out. or is this a non-issue entirely?

Obviously depends on the size and shape of the hump. I find most don't slow me down.

I haven't had a problem yet, but if I think there might be a clearance issue I always use the sport mode.

try going to google and typing:

site:m3post.com _____________ (put whatever you are looking for in the space where the line is)

it works a lot better than the forum's internal search function.

The following was posted log ago from a Euro listing, but not sure of its accuracy. Sounds about right.

What is the length of OEM wheel bolts? (I need it for proper spacer extended bolts) Thanks!

If you check this thread, you will find spacers that come with the proper lugs as a kit: http://www.m3post.com/forums/showthread.php?t=240884.

Thanks, but for spacers > 20mm H&R have the technology when the spacer is connected to the car first, and then the rim is connected to the spacer with the OEM bolts. That's why i need the length for it - that's what i was asked by the vendor..

Guys, whats the max tyre dimension (front and rear) that can fit on OEM 19''?
