well i just got the sport stars and they are pretty good looking. you can go to the imagine section and look for my post i have some pics of them on. the difference is the PRO starts have chromaly Steel with is stronger, and the SPORT stars have dom steel. either way they are both stronger then stock. i have read a few things on here about both bands full flight and ASR some pople say they are good some say they are junk but i have heard more band about the full flights. i have Pms a bunch of guys that have the ASR and no one has had any problems with them. one problem i had was the coating one the arms was really thin so i need to get them PC'ed. oh yeah im not to sure if your YFZ shocks will fit the arms the yfz shocks are fatter so they might rub on the back side of the upper arm. i will check where the location of the schok would be on the stock arms and see how much room there is there. so if there is more room with the ARS's then im sure you could run the shocks. i know pople use YFZ's with stock arms
