European N2 Race?

Maybe having just two different classes would be enough; an "N2" class and "SS class". The "N2" class regulations could be, for example, something like this;[list:9f2ad29269]
[*:9f2ad29269]Toyota AE86 unibody, material must be original. Sections outside the cabin area can be modified.
[*:9f2ad29269]Material on hatches and doors is free. Laminated glass windshield and tempered glass driver's side window required. Material on other windows is free (must be transparent!)
[*:9f2ad29269]Material on fenders and bumpers is free. Flares, spoilers and wings can be added as long as they do not extend further than 300mm from the car's original top-down silouette.
[*:9f2ad29269]Suspension and axles can be changed/modified but method of operation must remain the same, ie. McPherson struts in front, solid rear axle w/ multilink supension.
[*:9f2ad29269]Engine must be a normally aspirated Toyota 4A-GE. Any 16v or 20v variant is OK. Engine internals, manifolds, fuel system, ignition and engine control system are free.
[*:9f2ad29269]Transmission must be a Toyota T50. Internal gearing can be modified freely. Differential and final drive are free.
[*:9f2ad29269]Max. 15" wheel rim diameter and max 225mm tyre width.
[*:9f2ad29269]A 6-point roll cage, FIA approved seat and harness, a 2kg fire extinguisher and an externally operable kill switch are strongly recommended but not required.
[/list:u:9f2ad29269]

"SS class" would be for any other AE86 which doesn't fit into the N2 class. So, for example, 4A-GZE swaps, turbocharged cars, cars with completely different engines, etc.
