I can vouch for him and say he's running hottuning and I can also say he won't be rubbing :)
My rears are that low (or lower? dunno:nana:) with wider wheels and I have sweet sweet silence no matter how many people I carry :) I dunno how low I am compared to Stu at the front but when I first lowered my car it was even lower than that and all I heard was bumps from my subframe over humps...no scrubbing :)
