We’re not sure how Australias got so good at suspension bushes, but they’ve clearly stayed off the Bundaberg to get it right: two class champions in this year’s UK Time Attack Challenge plus numerous other front-runners were using SuperPro bushes. The two victors drove a massively turbocharged Evo 9 and a Vauxhall VX 220 respectively and used off-the-shelf kits in the set-up of their cars. Superpro brushes have been signed off by manufacturers including Subaru UK as being compliant enough for accessory ranges, but they're clearly still stiff enough to hold mental track cars on the right line.
