Do you have the arm braces? i was able to stop this on numerous cars but really even without them it should not do that. how old are your arms? they do tend to warp over time up to 4mm!

Arm braces and alloy rear hub carriers took away almost of the tire chatter that I was seeing.

Running different tire shores front and rear can do that. I am not saying that this is definitely your issue but it's worth trying a run with same tires all around and see if it disappears. If you have no other issue on the car the shaking out of the corners should disappear.

If you have the braces you will probably never need to replace them! They either warp or break and with the braces they are not going to warp. I am thinking you chatter has to do with the clutch in someway, a spring could be weak or broken, clutch bearing siezing up, grease in the bell from the bearing etc etc

Also added a Buku clutch , maybe that made for having to adjust shifting some ? The thing Rips with that clutch
The adjustment is based on how close you have the shoes set to the housing to start. I normall keep my 2-speeds pretty close so there is some play when hot, but not large gaps. If you adjust this, you will need to re-set the shift points (less distance to lock up). I never set these to stock settings, but to where it needs to get my shift point right.

Clutch change can make a difference as well.
