I bought these for my project, but I have changed directions. They are Forgeline RS:
8x17 and 9x17 with 245 and 275 Hoosier R6 track tires with @ 2-3 DEs on them.
They are designed to and WILL fit under normal 78-89 911's fenders with these size tires. ( or earlier bodies if you have SC/RS/Carrera flairs ). You could also move the front tires to the rears and buy a 225 or so for the front.
Local pick up would be great, but I will ship them anyway you want. (They cost me @$190.00 to get them to me from Ca. last Spring via FEX.)
$1,500 plus shipping..
