like since 2009 ive used RT615 and RT615Ks. If you dont have the basics down, i wouldnt suggest it since they mask up a lot of things. They also drive differently, at least with the RA1s. There are a lot of street tires that are almost as fast as r comps. like the RS3 or the BFG Rival. I only switched because I wanted to, needed tires, and I wanted to drive on a 15" wheel again.
