Will be using with ARB blocks.
Afaik super pro n powerflow only do standard replacement bushes, not blocks. So wont correct the geometry of a lowered car
you dont need to get rose jointed TCAs to run the G-ladersiete outer bushes, although using G40 items are better to start off with.ive ran with both in my time, and as phil has found, the powerflex ones have torn, which isnt good!
