Ok so i have H&R springs and tqf rear tie bar. Springs are great but it seems that they drop to low and im desperatly waiting for them koni yellows to come out. I'm just giving a heads up to people on the forum that if you lowered your car with H&R or sportlines taking hard turns is going to be a challenge. Without that stiff dampning of the shock the car will just bounce around turns. Second the tqf rear bar is great but also if you lowered your car your exhuast will hit the bar every bump... I removed my rear bar for now till i get shocks, but a easy solution is cut a bicycle grip in half and zip tie it around the bar where the exhuast hits.
