I found at blyton the car had a lot of body roll which resulted on the rear tyre rubbing the arch on a couple of corners so i made some alterations to the rear susupension. First was some genuine hilo's on the rear, mainly because the cheapo set that was in there has some slop in the hole that the long pin goes in to and I was concerned a big bump could cause it to shear. the other is that the are almost at maximum adjustment and didn't have many threads left in the cone which I didn't like. so for comparison look at how much further the genuine one is wound in compared to the cheapo one for the same ride height, and also how much beefier the big pin is (and the the pin which goes into the big bolt is a much better fit and much longer).

second thing to note is the size of the spring platform, much bigger with a large radius making the spring rate more progressive = better handling

next was the rear ARB, generally straight forward to fit apart from the bushes in the drop links being too tight on the bolts so I had to drill them out.
(the drop link isn't actually connected to the bar in the first photo)

A couple of things to note for anyone wanting to fit one of these, first is you may find some of the sleeves on the drop link bushes are too tight for the bolt to pass through - I had to drill a couple out. Also make sure you use loctitie or similar on the top droplink bolt (that screws into the plate on the radius arm) as this will un-do itself otherwise. Also once I bolted up the aluminium bush blocks the bar went incredibly tight and couldn't be moved by hand, the blocks were machined too tight so I loosened the bolts, smeared in some lapping past then nipped them up and rotated the bar until it could move by hand with the bolts fully tight but not so there was any play.
Another thing I did when it was apart is to modify the Hilo's. when set at a lowish ride height the hilo's can drop out of position on the rubber cone when the car is jacked up - obviously not safe if the wheel drops low enough on the road. I got an A series oil pressure relief valve spring, cut it in half and dropped it into the hole in the bolt of the hilo, put the long rod in and pushed it until the spring was coil bound and measured how much of the pin was sticking out, cut this amount (plus 1mm) off the end of the pin so when pushed in it goes all the way. this keeps the seat of the hilo in position on the rubber cone when the suspension drops.

the small bit of pin above the spring is what was cut off
The ride is now fantastic, lovely and smooth with the new cones but progressive on corners and bigger bumps, the ARB is fantastic at keeping the car flat and seems to help to put the power down out of corners, cant wait to try it on a track
