[V8] UFO Rotors and Calipers

[Chuck Pierce]

Brian I have a set of used UFO's from when I  first got my car
and just replaced everything (rotors and pads) when I did the brakes.
If some one has the min. thickness I will check them later today.
This could save you some money.
The freight to the wrong coast might be a bit steep though

Formerly a 91 20v Avant Owner
Still have clutch kit and some euro lights for sale on the marketplace
