This is the newest system Davis Technologies offers. I Bought this system brand new for $9,995.00 in April 2016. Oval track asphalt TMS-9500-SL Davis Technologies Traction Control device with hand held programmer. Used for one day at practice for less than 100 laps. We Found system was not beneficial for the type of racing we were doing. Still in original box with all documentation Like new. I Will ship to Davis Technologies for quality assurance and can ship direct to buyer from there. All reasonable offers will be considered.
