I take it your tracking it, make sure the brake pads arent running thin, front/back/inside and outside.
Basic comprehensive inspection of all mounts, engine, trans, rear end, guibo etc. Inspect the fuel line at the tank and engine for corrosion of the clamps, rubbing, dried hoses etc., including the cooling system. The trans fluid should be changed with a full synthetic and not the cheapie dextron III, I got a hold of royal purple for under 4 bux a quart here in the US, dont want anything thats going to break down under stress.
dont put the injector cleaner in unless your going to change the oil right after, it will contaminate it.
Cutting the rotor shields may actually cause them to run hotter, dont guess unless your absolutly positive before making a change like that. Common sence doesnt always prevail on a car such as yours that was engineered to run fast as hell on an autobahn.
thats about it for now...I'll think of more as soon as I post this I'm sure.
