I did an early deep 6 like the 4.5's, and it looked great.....might be interesting to do the later 6's that way, they are shallower on the outside of the rim...might look pretty good! I've since upgraded to 911R's on the rear.

By the way.....I was riding with Randy Well's last November in an RGruppe drive...and Howard's 67 was being driven by a buddy of his....that car with the 4.5's had NO problem keeping up with all of us with later car's and wider tires.......

From memory Howard's car has 165/15 Michelin XZX's on it.
