LMB F400

We've had several phone calls recently about our F400 Cup that runs within the Doodsons Motorsport Supertwin 650/F400 series grid at Thundersport GB for 2012.

For the avoidance of doubt, please be aware that technical regulations for the LMB F400 Cup will largely match that set out by the ACU and thus can be found in the ACU Handbook which can be downloaded via the link below...

LMB F400 will run road legal tyres unless wet conditions are declared by the Clerk of the Course at which point 'wet' tyres may be utilised.

5.5 inch rear rims are permissible.
