Hello there - thanks for the videos - already used them to follow your steps in bleeding brakes and clutch. I have a 1967 MG Midget with what I assume to be the original 4.22 diff. The car is very under-geared for general driving around. I know that in 1968 the diff was changed to 3.9. I'm considering going a step further and fitting a 3.7 diff. With your obvious knowledge of these things - do you think that would be okay - would the 3.9 make a big difference at 60/70mph - lowering the revs?

[@mgmidget-thebirthofaraceca4349]

The 4.2 increased the ratio around 15% and is noticeable on acceleration. I'm expecting to run out of revs now on long straights. I've a track day next week which will confirm my suspicions. the 3.9 is the most common size and excellent all round for normal everyday driving but for sprint and hillclimbs its too long. ive got a 4.55 which will be my next stop if needed. if you do mostly motorway cruising or highways then a 3.7 makes sense at the expense of acceleration/fun factor? your choice but not too big a job to swap back if you dont like it. good luck

what would that cost in a shop mg car needs a diff?

[@mgmidget-thebirthofaraceca4349]

Not sure as it really depends where you are in the world

[@gavinivers8941]

I'm I right in thinking you are still not running a LSD? Are you not allowed an LSD in the class you are running in?

[@mgmidget-thebirthofaraceca4349]

Correct. I can’t use an LSD in this class of the MGCC speed series. It actually makes diff changes much easier to do

[@jimmurphy4703]

Will a diff from an early midget fit a 1933 J2 ?

[@mgmidget-thebirthofaraceca4349]

Apologies I’ve no experience of the J2 to know one way or another

Do you make house calls in the States? I need a lot of work done, and you are so dog-gone fast... I would be able to buy you a pint at the local...

Unfortunately not. Im based in the UK, so that will be one looooooony road trip!!
