So I dont know if you guys already know this or not but Kenstyle just released a kit that looks almost exactly like their kit for the RS5.0 for mass production. The kits only difference between the RS5.0's kit is the back end from what I can see, the pictures are really small so its hard to really get a good idea. Its being sold for $1,299.00 and is poly urethane. Check out the link below for Optomize Scion. I dont know how you 5.0's out there feel about this but I wouldnt be too happy...
