Well, I milled away the triangular blocks to move the shock tower forward, and with some 20 degree (I think) castor blocks fitted it fixed my problem without having to cut down the Losi balljoints or fit shorter ones.
The B4 front shocks are too long though, I thought I might get away with them, but they fully compress way before the chassis hits the floor

My options are a taller front tower, or some shorter threaded bodies - do AE do shorter threaded bodies?
I just need to see how much I can slam the shell now without milling away the chassis, as I'd rather keep the stiffness.
I might also look at fitting Losi rear wingmounts to the rear tower to do away with a wing wire.
