2007 250 Production Rules
|
|
|
The production rules in the MA GCR’s were originally
targeted as being the rules for 250 Production class in the MRRDA. However
these rules can not really apply to the now ageing 250’s.
As a
result we have been advised by MA that the class will be renamed to MRRDA
250 class and the following rules will apply for this class only, as amendments
to the existing published production class rules:
- Tyres. Allow slicks/ wets, etc
- Exhaust mufflers or
“stingers” may be changed.
- Oil injection can be removed,
and “premix” fuel used.
- Braided brake lines allowed.
