Contact Craig (PWR_RYD93) he is friends with the owner of Rockford Motorsports. Craig is a real nice guy and may be able to help you out with any info or question you have. He runs low 10's with his S-Trim. Craig has been able to help me out a couple times, I have nothing but good things to say about him
