haha, yeah there was some crack being smoked on that other forum. That one guy seems to absolutely hate his 501X so I'm not sure why he still has it. He's gone from quoting a shoddy article in a magazine where a touring car driver setup a 501X and it was apparently 'the worst over the bumps' and I quote "the most like a touring car". never!
but nah, I don't think I'll be trying these as the car is good how it is already.
