Silly guys towing with XJs...
I fit our lowered RX3 and front splitter on a uhaul trailer with little effort, you should be ok.
Also, why would you want Brian to drive it down the track? If memory serves me correct, the last RX7 he had on the track got him too excited and the result was touching a rotor to the plate

and that was just a little twin turbo RE, not the monster twin charger REW this beast is housing...
Sorry B, it'll be a while before you can redeem yourself and face it, we don't have much to pick on
