A friend just aquired a 07 4runner 4wd, no lockers or diff lock, but it does have down hill assent control, and what I believe is stability control. While he was researching for some improved suspension, he was told by an installer here in Tucson that you can have problems with certain lifts and the stability control program. Is this really the case with the Donahoe coilovers? I have read quite a few posts from 4runner owners here, and don't recall seeing anything referring to this, but was curious what owners here have found. Any input would be greatl appreciated, Thanks
