I have R1 and have good luck with car no real complaints with car. I'm a dirt racer that just recently jump into on road. I purchased my R1 in September at the time I bought it the H4 had not been released yet. H4 was my 2nd option It was at same price point. I guess what I'm trying to say is dose anyone have experience with both of these cars, and is there a real performance difference between the 2. I may go ahead and buy H4 before winners out. Thanks for any feedback anyone may have.
