Julian - drop me a PM re the twinpack.
Tony - If doing what you say involves a bit of a hunt around, no thanks, if you don't want to put your thin rules on this forum or in the clear some other way, that is up to you.
I recommended the BSRT axle becuase the tyres are superb for slamming the front of cars, the wheels look good and are true, and it is a decent axle. Why such parts are banned is beyond me. Do you check axles? Would you even know how the BSRT ones differ if the wheels were removed?
This is my last past in the SCHORC section, it is too much like banging one's head against the wall, and it is why I started the real snakepit. If SCHORCers want to be hooked up with the right gear, or discuss rules sans aggro, they know where to find me.
