They are a massive improvement over the original design (if traction is what you are after!), look the same from the side so retain that 70's profile, and aren't that expensive.

Donna and I just got home from dinner at a new friends place. He has a '70 Boss Mustang, an XY GT, a HQ GTS 4-door and is now going to get a van after seeing mine. His cars are immaculate, but he had a big nostalgia fit when we turned up in the van. It was so strange.... he has 3 cars a lot of people would kill for and he turned his back on them and was all over my van. He said he loved the way it looked with the mags and T/A's.

I of course, was all over his cars!
