Wolf Performance did the conversion on my 2009 4/4 sport, which had Gaz adjustable shocks originally. These were replaced with Rutherford Avos front and rear, along with Panhard rod, anti tramp bars and brake reaction bars.
But by far the most work (and expense) was at the front where Cain completely reset the front geometry of the. car (requiring a lot of jigging, heating and bending), dialing in more caster and a touch of neg camber and basically setting the car up as it should have been at the factory during the build. The geometry was all over the place originally, and required extensive work to get it where it should be. There was 3 degrees of caster on the left front wheel and 4.5 degrees on the right front wheel - no wonder it handled a bit oddly! A pair of chromoly kingpins, new stub axles, Rutherford bump and return springs and a huge dollop of applied expertise completed the conversion.
About £10k worth of work, but the car is now exceptional compared to other Trads I have driven and gets ragged regularly, where as before the conversion I did not have the confidence to do that.
I have heard several times the SSL suspension mounting system at the rear is less than optimal and race cars do not use it, although for road cars it is supposed to add comfort. This is probably true, but it was not what I was looking for.
I will never get my money back of course, but the car is now so good that I will probably never sell it anyway.
And there lies the problem, we spend a small fortune setting up our cars as we like them and then we can't part with them.....it's a trap
