So jacked the rear up tonight so I could put spring washers on the caliper mount bolts but to my (not so) surprise they already had them! (I bloody knew they were there) Well on the drivers side anyway as haven't done passengers yet. But seeing as they are smaller than the bolt head they weren't visible... so put new ones anyway that are shiny so that shouldn't be a problem now.
While I was underneath the rear I could see that the outer CV is hitting part of the body which is why the clamp keeps braking and that's also split the CV boot fuuuuuuu. So folded up the steel and gave it a bash with a hammer which will hopefully be enough clearence above the axle. The passenger side seems fine though so will leave that alone. I tried jacking up the rear control arm as much as possible to test clearence but after a certain point the whole car was getting jacked up as well so will just have to see how it goes for now. Photo is pre-folding/bashing
Edit: didn't realise pic was blurry til now will try get a clearer one tomorrow.
but then realised that the suspension was at full droop causing the sway bar link's to pull the bar itself up closer to the sump. When I test fitted the plates I had the front wheels on ramps so of course having the control arms at ride height meant the sway bar link's pulled the bar down to about 20mm clearence. I'll have to describe this to Ian when I phone him this week and hope that it's sufficient! Also solved the securing of the front brake hoses issue,after a lot of googling and head scratching I finally came up with the idea to use a t-bolt clamp around the threaded sleeve and place a P clamp on the end of the thread of the bolt and fasten with a nyloc nut! Came out pretty good I reckon! After front height is set up again I'll phone Ian to book recheck
