just a quickie, re the r32 brakes versus the porsche (brembo) brakes, the porsche brakes = lighter, use std disks, therefore cheaper consumables, much better feel, better clamping force (4 pistons versus 1) and IMHO look better (this is subjective though), the r32 brakes better heat dissapation as bigger disc.
I went with the porcshe set up, but I don't do lots of heavy duty track work, necessitating the greater heat resistance, if I did I would prob have gone for the R32, otherwise for street and moderate track the porsche are much better IMHO (for the reasons stated above)
