Have any of you guys ever used Superlift's 2.5" lift kit? I've heard bad things about Rough Country's small suspension lift, but was wondering if there are any issues with Superlift's. I am wanting to put it on my '99 2 door Tahoe. I want to run a 31" or 33" tire on 17" wheels with about 4.56" of backspacing and -12mm offset. This is going to be an everyday driver so I don't want to go to big with the lift and tires. Any advice would be helpful.
