hi ian
iam getting em of supplier and is already made n packaged. As for GTST4 should be a problem as they have similar running gear as GTR...I have asked supplier and awaiting for response. I like the idea that you have there but unfortunately whats stated by the supplier above on what the TSC can do is pretty much it, but still awsome for circuit work or when driving in the wet..or if on dragway n switching to 2wd fro that massive burnout n flick of a switch back to 4wd. cheers aaron
