HI,well i just installed a complete pro race kit...without going into detail, quality and service is number one ..it took 4 hrs for a total install. pinion angle 2.5 .coffes included .....i disconnected the front sway bar and i could not tell the difference weaving in and out of traffic at highway speeds ,infact steering felt much tighter...i will go to the track next weak and see if my 60 ft are lower
