[urq] Re: B5 S4 vs A8 Rotors

[John Karasaki]

The ur-S4 front rotor can not be used on the urq.  There hat is too deep.

The ur-S4 front rotor is NOT the same as the 5kt/200tq 10v rotor.

The B5 S4 rotor can be used with BIRA system 2 brackets and Boxster S 
calipers but this setup requires a 17" wheel.

If you want to stay with 15" wheels, the A4 rotor is about the biggest you 
can use.  The A8 rotor requires a 16" wheel.

I have a setup that uses Wilwood 4 piston calipers with the original urq 
rotors and will fit under 15" wheels.  As I don't have a urq anymore, I 
could be convinced to sell the kit. ;)

Regards,

John
