I got my X6 sq. running finally this weekend and tried a more 'Benelux' setup without E speed hangers. The aim was to make the rear upper link angle more parallel with the lower wishbone than the standard setup (ie lower at inside and or higher at outside), without using what I consider to be short links. I took 1mm off the inner plastic mount and used low rise balljoints, and on the outside used racers edge hubs with 3 washers under balljoint (higher than on AE hubs). This makes the upper link pretty much parallel with the lower wishbone. As far as I can work out, this very roughly equates to the kind of geometry you get on the C4.1 when using about the 5th hole up on the inner mount. I also used only 2 degree rear anti squat and only 3 degree toe at rear. Coming from the B4, it was fantastic, what a difference. It was all going great until I popped a wheelie on the straight, lost control and went full speed into a wooden post. Result, broken chassis. I'm 100% sure no other car would have survived either. Loving the X6 sq. though, the build quality is fantastic, it feels like a proper 'engineered' product. Some other UK drivers should try this different flavour setup and see what they think.. If anyone has a plastic stick pack chassis going spare, please let me know! cheers.
