Peter....as discussed earlier, this is what I was talking about with regards to the front ARB.
To quote John:
"No, was advised against it. To fit the front one too would make the car very stiff, so in the wet or on our crappy bumby roads, the car would slide around or skip on the bumps. Therefore, leaving some flexibility in the front means the car can grip better. If it was a dedicated track car, then there would be no question of fitting both"
