just put brakes on from a mk3 1.8 20vt?
only way you'll get them behind the 16v rims is with spacers
i used 15mm spacers as a temp measure while waiting for my new wheels, they only just cleared with them (i was only moving the car up and down the drive tho so couldn't tell you what it would drive like)
how about some brembo disks grooved like ATE Powerdisks...
