Brian, I have become pretty familiar with the innards of my cars front end in advance of swapping my bumper to the m-tech one. The new bumper requires different air ducts for the brakes and oil cooler, but there are already ducts there with my standard bumper. Doesn't you car already have cooling ducts for the brakes? Or are you trying to improve upon the stock ones? You'll have to excuse my ignorance on the E90 version of the 335
Anyway, you're a braver man than me to pull apart an E9X, good work
Where do you plan to track your car? I would love to do this too, but it would get expensive quick for me as I'd only want to do it with an manual transmission, so I would need an E30 M3 or a Z3 M Coupe
