There are other resellers of the H&R RSS package. Kenny Brown Performance, Lethal Performance, Maximum Motorsports and others.Tried to order H&R coilovers from tire rack. They quoted me about 3 weeks from Germany. A bit too long for me. I ordered koni sports instead and I already received them. I went with the gt500 style as I got a good deal on a steeda upper mount for that style. After speaking to the rep with Steeda, I went with boss comp springs. He said they were pretty close to the reg comp springs. Maybe less lowering overall. They were the last s197 spring they developed. Def recommended a stiffer shock package than stock GT.
