I just got my Ben Calimer rebuilt MT82 installed with a Spec 1 and Aluminum flywheel. Here are my first impressions. Getting into the car and feeling the shifter was like getting into someone elses car. Far crisper and solid then I remember! My friend who did the install is a aircraft mechanic and maybe his reinstalling of the MGW and Blowfish bracket has some thing to do with it! I took it easy because of the new clutch but the in general the shifting was much better then before and no hesitation going into 3rd or 5th under medium load. The old box needed a gentle push to the side to go into 3rd even under light load. Down shifting with rev matching was easier as the engine revved quicker then before, I guess due to the lighter flywheel. I have a time trail on the 11th so I will find out how its like under track conditions. But so far its quite a marked improvement!
