Hex axle option

B4 with B6 front end and Yokomo shocks. Ran it at the track with different tires. Really not bad. Full range of motion. Ran the middle holes on the arms and it was pretty much back to normal for this car.

Broke bulkhead #2 with this setup, so I’m thinking the little bit of material you bore out from the hinges is weakening the bulkhead.

An aluminum bulkhead would solve it but good luck finding one. You could go back to B4 arms, but bore out the outer arm hinges, but I wager it will just start breaking there instead of the bulkhead. B4 arms are more expensive than B4 bulkheads, so it might do to just stock up on bulkheads since they’re still $2.99 vs $18 for the arms.
