Finally got good clearance now!
Got some more bush holders, tried to cut them up and weld another 15mm in, made a pigs ear of it and got pissed off.
Next I put a 20mm front ARB on, and at the same time switched to the e36 ARB bush holders. £4 each from BMW. These have two bolt holes rather than one and a lug, and the second bolt hole lines perfectly up with the subframe bolt. The subframe already has a bump where the bolt comes out so it's just a matter of putting three washers on the original bolt and a dead simple thin plate with two holes across the bush holder to keep the bush in place. Now I can put the bar anywhere I want using more/fewer washers
Need to be aware that the subframe bolt doesn't have that much engagement to start with but not a problem for where I need it.
No more rubbing and buzzing for me now!!
