Mitsubishi FTO DE 4/6CYL 1994-1999 (See Notes 989). Weight aside, the more the better. Race cars have elaborate roll cages not just to protect the occupant, a good proportion of its job is to stiffen the chassis.
As described, worked a treat in my Ra28 Celica with my Whiteline KSB601 Front Strut Tower Brace .
Good to have these if you need to fiddle with a carby now and then, by using these I get quick access to take my air filter off the carby.
