Update: This weekend I fitted the drivers side Vibratechnics engine mount to replace the std one that had sheared right through, I believe this was what was causing the vibration when turning hard right. I noticed a witness mark where something had been rubbing the subframe cradle at that point. I drilled through another 2 vibratechnics mounts to effectively make a 10mm spacer for each side which raises the engine by 10mm, this helps the angle of the front driveshafts a bit.
I am now waiting for the WRC hubs to come from MK so that I can bolt the front end back together plus waiting on new boost hoses from Demon Tweeks for the new intercooler.
After I get back on the road I will take it to get the exhaust slightly re-routed as I now have a better route with the front ARB replaced with the bladed one.
