Here is some info I have on the Xmods from RadioShack. They are 1:28 scale not 1:60.
Some of the cars should be Starter sets Nissan Skyline, Acura RSX, Honda Civic (2 colors), Toyota Supra (2 colors), also body sets of each car as well. There will be Speed sets, Tire Sets, Stearing and Suspension set and (get this) AWD Kit, and a tool kit.
Some special order parts my even be a lap counter and transponders and custom decal sets. Can't wait to see how much of this stuff is actualy going to hit the stores. I'll post prices as soon as I know for sure. I do know that the catalog numbers will start with 60-8001 for the first starter and 60-8501 for the first upgrade parts.
Starter Kits are 60-8001 Nissan Skyline, 60-8002 Acura RSX, 60-8003 Honda Civic #1, 60-8004 Honda Civic #2, 60-8005 Toyota Supra #1, and 60-8006 Toyota Supra #2.
According to the toy guide the Xmods are to arrive in stores late October.
