Finally got round to testing the M08 at the weekend, on carpet so not the outdoor tarmac but putting that aside, wow......never driven a rwd m-chassis, was expecting to have a really loose rear end (ooer) but it was locked in. It would understeer but I need to add a lot of weight to get up to the class minimum so hopefully can improve the front end grip with some weight on the nose.

Braking was interesting, fine in a straight line but do it with a lot of steering and it would hook in. This was great for a tight indoor track however to get the nose in to the apex. No grip roll or anything. I ran the M07 before it on the day and it was all over the place there on the high grip.

The outdoor track is large with sweeping bends and bumpy so it may turn out to be a disaster there but it's something new to try plus it will be sat under the same 'fwd' shell so running stealth to start with and can swap to the M07 if required
i found the rear end really easy to spin out(loose). so i started with adjusting damper position and tamiya tire compound from S-Grips D60 radials to medium ones in the the rear and now the soft S-grips or on the front. and hope to do testing next time i am at the track.

Probably want the softer ones on the rear if you are spinning out? My second outing with it wasn't quite as good, needs more front end grip and I lost the rear a couple of times so will now give it a proper going over before I use it again

I am going to the N.A.S.C.A.R. track. i got off the phone with great hobbies today they said the diff is out of stock and no ETA on restock times to the supplier.
I am also inquiring with a few other hobby shops i know of in Ontario for the diff to see what they say. I shall keep you informed on that if you would like?

54471 is the part number for a complete gear diff. They have been hard to get recently but RCMart in HK have them.

It is possible to piece together from spares but in typical Tamiya fashion it requires lots of parts, some of which are also hard to get hold of individually. Had to do that myself within the last couple of months and I was relying on toolbox spares to finish it off. So I would definitely recommend tracking down the full diff to start with.

at the club they retain the stock diff gear ratio to my current understanding so that on would not work. you need the 52T diff as the one you linked is 50T.

Default M08 rear stepping out

If the m08 is stepping out
out of the corner (on power)
- shorter camber links
- more rear toe-in
- straighter from toe (go to zero toe)
- more front droop (so that weight is transferred to rear)
- short or medium wheelbase
- make rear tread narrower (use thinner drive hexes)
- use more front kickup ( to encourage weight transfer to rear)
- use lower rear roll centre to cause downward jacking)
-
stickier rear tires

Into corner (off power)
- use longer wheelbase
- limit rear droop ( so weight doesn't transfer to front)
- use less front kickup (less kickup also limits rear to front weight transfer)
- use more rear toe
- use front toe out
- use shorter rear camber links
- use higher front roll centre to create upward jacking
- use stickier rear tires

Lots of fun things to play with... enjoy!

Some of these are vague, or I personally disagree with.
