I'd like to get the te37's, but am weary of getting 19's (tire cost, bending, etc.), but would like to increase the width. So, I'm considering the volk 17x8.5 +30 front and 17x9.5 +28 rear combo; my question is: will this combo fit over the track editions brembo calipers, and if so, what offset is required?

I'm assuming there wont be any problems with speedo readings, but will these have an adverse effect on the traction control system(s)?

Now, having betrayed my inclination toward the 17's, anyone care to persuade me to get the 19's (other than aesthetic?)
