Just a thought, since IT cars can run in STU I would consider not grouping STU in any group with IT. That would allow Two drivers to enter the same car in different groups giving you a potential bump in entries.
Dan: You want to run ITC, ITE and STU??????????????
No, just ITE & STU. My car's not classed in ITC.
So, what group is DSR in?
Just put a SRF body on it. Sandbag so you don't end up in impound. No one will look under the body work.
