Turned out that due to the limited space on the back of my car I had to mount the anti roll bar beam quite close to the underside of the car to avoid the transverse exhaust, this meant the drop links were not long enough. I sent a text to MK and the next day he had made me up some bespoke ones and they should be with me this week (thurs). Happy with that.
Looking forward to sailing in the arb and then softening the springs again to make a supple road car. Already it is bonkers on roundabouts being so short and light, you can just lean on the front end. May need to get it on a wet handling track to explore a bit more.
