T1 is production class. T2 is modified production and T3 is the prototype class while T4 is for trucks. Now that manufacturers have been banned from entering works T3 cars their efforts are being aimed at the T2 class where they can practice their cheque book racing. As such T1 is becoming the class for the amateur competitor. The regulations for T1 are very strict, the engine must be in the standard tune and all braking and suspension components must remain the same.
Shock absorbers can be uprated and braking materials can be changed.
Thus Bob's race car differs very little from the standard road going short wheelbase Colorado. The Interior is gutted and a roll cage and bucket seats fitted as well as fire extinguishers and engine cut out switches. Underneath a skid plate protects the front suspension and damping is competently carried out by HT units at each corner. The car is then finished in its sponsor Castrol's livery to make a very photogenic vehicle. It is not that Bob Close's vehicle in itself is very special but it is what the face of UK off road motorsport should look like if it is to raise the budgets it needs.
