Thanks Tommi! Here's a lineup of all the F-103 chassis released by Tamiya...
F-103 - the standard chassis... (Sauber C12, Ferrari 412T1)
F-103L - long wheelbase version (+1 inch) for Indy Bodies (Newman Haas Lola Ford, Rahal Hogan Lola Honda)
F-103RS - with some hop ups (chassis only)
F-103RX - with a few more hop-ups (chassis only)
F-103LM - with wide plate main chassis and LeMans body (Toyota GT-one, Audi R8R)
F-103LM TRF - wide plate main chassis with max hopups (chassis only)
F-103GT - standard chassis with parts to use touring car tires (chassis only, Courage LC70 Mugen)
F-103RM - basically an evolution of the F-103RX (M-type, T-type)
F-103R - the anniversary version
Damn that's allot of variations of one chassis.
Does anyone else remember when it was just the Road Wizzard, then the F101 and F102. Not F102**, or F102R* or TRF Road Wizzard MSXXXRE. It's sort of funny. I thought the 415 had allot of rolling changes.
