Racelands are ONLY good for if you want to slam the car for looks. Otherwise they belong in the garbage. If you are looking for performance BC is "ok", KW is just absurdly expensive for not having any variety (400lb front and rear, no variation), UPR is meh, Team Z is good for drag, and Maximum Motorsports is where you want to go for corners.
I went with Maximum Motorsports on my car and the handling is phenomenal. I did pay around $1600 for the entire set up front and rear... Like i said, you get what you pay for.
