I wasn't sure of the specs but I wouldn't wish the mass of my Mustang's 
narrowed 9" on any self respecting TR. On the plus side it might move 
the weight distribution toward 50:50 but so would a bag of cement in the 
trunk.

I see the 8" in Nitrous burning Mustangs north of 650hp - no-doubt with 
after-market upgrades. They are cheap...

Cheers,
