I would however disallow non Tamiya hops ups, just to keep things more aligned. Again none of them would give a huge advantage, with the exception of the Yeah racing motor mount, which gives greater gear options.
This thinking ruins spec classes, set guidelines and stick to them. Allowing hop ups and gearing changes will just spread the cars out and make the racing boring. The rules listed above by SteveM are the same as my club and all the modifications that should be allowed. Let's not destroy a good entry level class, emphasis should be on getting better as a driver instead of just building a better car.
