Megabusa restoration: ARB (Anti Roll Bar)

I was happy enough with the road holding on my Megabusa but when I spoke to Simon at Sitec Racing he advised me to get some ARB(s). Simon's advice is that the roadholding can be made even better on the track with ARB's. As he is going to be employed to set up my suspension soon, then I guess, I need to take his advice.

I thought about purchasing s/h parts but decided a new set would have all the bits and pieces supplied and be a straightforward fit (wrong!).

I purchased the front and rear ARB kit for a Westfield from Playskool Motorsport. Like all aftermarket products for my model of Westfield (apparently) it did not fit out of the box. The main problem was at the rear bar:

1) The instructions were unclear about the position of the plates to attach the drop arms at the rear to the lower wishbones.

2) The rear upper pivot points requires removing the fuel tank as the bolts cannot be removed and inserted otherwise.

The first problem was easy enough I just posted a thread on the Westfield technical forum and that matter was put to bed almost instantly. There are lots and lots of people who have fitted that kit.

The second problem resulted in me refabricating the rear pivot point brackets by putting an offset into the pivot point. I then mounted them on the rear wishbone mounts instead of the front. I did not want to remove the tank at this stage as the roll cage would have to be removed. I cannot see why this will affect the roll bar performance in any way.

The biggest problem with the front ARB was that the site for the front ARB was obstructed by the radiator, the bottom hose and the cooling fan.
