On the B4, rear toe is set to 3 degrees with part #9571 (anti-squat is adj. with shims), does anyone make 2 or 1 degree arm mounts? I can't find any info.

I would have to look, bit I am pretty sure my 4.1 kit came with several different toe/ arm mounts. -Jeff

Correct, the 4.1 comes with four different mounts for toe but it's a different design. I don't believe they are interchangeable. The B44.1 also is adjustable but another design. Why must they keep redesigning everthing!

So you have to keep buying new!

I already knew that, I wanted a realistic answer.

I thought the old and new mounts were interchangeable between the 4 and 4.1 series? I was under the impression that the newer 7487 toe mounts just had the small cutout for the ballast weight added, but were otherwise the same as far as mounting them to the chassis(?)

The new mounts will bolt up to your older B4, 100% sure on that. No need for anything else new other than the mount set.

B4 Arm Mount part # 9571


B4.1 Arm Mount part # 7487


B44.1 Arm Mount part # 9726

I did find one hobby site that list part # 7487 fitting B4, B4.1, T4, T4.1, SC10

#7487 will fit both B4 and B4.1
and they come in 2.5°, 3°, 3.5°, 4°

As far as I am aware no one does different toe in suspension arm mounts for the B44/B44.1
