Re: G60 brake upgrades?

[John Karasaki <johkar@teleport.com>]

According to Sportwheels, the A8 rotors are a direct swap for the A4 rotors
and they sell the mounting bracket to move the caliper out accordingly.

I have a pair of A8 rotors sitting in my garage.  Going from memory, the A8
rotors are 312mm x 25.4 mm.  I can measure them again if anyone wants exact
dimensions.

I can attest that they are a direct fit on the 5ktq and the V8 with S4
strut/hub assemblies.

A Colorado lister has used these rotors and the A8 calipers.  I quote:

I hope some of you on the list tries this and posts the results.  I didn't
go this route because I could not find inexpensive A8 calipers and carriers
and I wanted the 4 piston Porsche calipers anyway.

If any lister has done this, please post your opinions.  Also, if someone
knows where to get the A8 caliper gear very inexpensively, please let me
know! ;)
