Thanks guys
Probably not going to run aftermarket rears, unless I can find some cheap Brembo rears (because as we all know, they are a superior design to the Alcon's and I should have probably bought Brembo's according to some forum experts).. even then, I'll paint them the same as the Alcons, because the colour combo really seems to work with the black rims and polished lips.
Braided lines are next on the list
As for rims fitting over them, if your stock rims fit WRX 4 pots with a decent amount of clearance (i.e. 10mm or more), they should fit over these.. best you do your research though if you're looking at buying any.
For those interested, the rotors are 330mm (same as Brembo), and the calipers are similar size to the Brembo's... maybe a touch bigger. They are a sh*tload lighter than the OEM Brembo's too.
