I just 136'd my 02 Viper ER. Adjusted the susp as per Hartman rec. Pulled the front limiters to expose 30mm of thread and set the transfer rods to the first ring.The rear of the skid is still off the ground. Thinkin I need drop brackets.So would I want, 1" or 2" drop brackets? The rear of the track is about 1" or so off the floor.
