is it just me, or does the BBK have less rotor "surface" area?
old rotor had 2.5 inches of rotor surface, new kit has 2.25 inches...

does that matter?

You're up too early. Go back to sleep!

I am no engineer, but as you know, surface area is two-dimensional, i.e., Area = height x length. The stock rotor actually has a surface that is approx. 2.25 inches high. I took my yardstick back out to the garage (sorry I don't have calipers with me). However, the outer diameter of the stock rotor is about 1" less than that of the Brembo one. The diameter of the wheel too is directly proportional to surface area since Area of a circle = pi*r^2, isn't it? You can calculate the difference between the larger circle (O.D.1) and smaller circle (O.D.2) and come up with surface area if you're really that curious, but this is a moot point, because frictionally speaking, what also matters is the braking surface and pressure exerted on that surface. The aftermarket brake pad surface seems larger than that of the stock one, which uses only 2 pistons.

Example: Back to the issue of outer diameter. Think of yourself as an ant that is racing around a circular track (i.e., my brake rotor). If you're walking on a brake rotor that has an outer diameter of 14" vs one that is 13", your track times would be much longer on that 14" rotor.

One last thought: I would think that the larger the rotor diameter, the more the rotational inertia. In dealing with unsprung weight, I would imagine it best to try minimizing that as you push the rotors outward in design. Tonya Harding spins in ice circles more quickly when her arms are closer to her body (with or without a crowbar in her hand).

Don't know.

Looks off in your mind? Or off in person? I never took photos of the entire side of the car after the install. Most of the modding I am doing has a dual purpose. Given the choice of form or function, I usually choose the latter, but of course looks are very important too. The front brakes are more important to me because this is where most of the stopping force is (hence the size of the front vs rear brakes). The rears will likely be changed to in time for symmetry.

I think it looks okay, because the rear calipers are incognito with the color of my wheels and car. I do think it would look better if both front and rear were Brembos though.

looks hawt

In that case, when's the install date for the rear Brembos? You know it's on order already

Did you ever concider the 15" Brembo BBK?

Yes, overkill IMO, and the space between the caliper and 19" wheel would have been very close from what I was told. I look at the E90 as a balancing act.

That kids, is how you mod a car. Quality parts

mosport70 · 02-22-2007, 10:49 PM

Thanks for keeping the 330 faithful glued to e90post. Great work on the install.

SV Concepts · 03-05-2007, 07:33 PM
