Roll centre/bump steer kit, worth it??
 

Due to the old rot having got to the front of my Spec B (2005 3.0 pre-facelift) I got a set of hubs, brake backing plates and alloy wishbones on the way.

Obviously I’m going with polybushes (probably superpro) on the inner end of the wishbone with caster and anti lift properties, but as the car is lowered (30mm on pinks) I’m considering a bump steer/roll centre adjust kit has anybody got any experience of these?
