I drove the Hyper 7 pro for 3 years and it rocks. I am actually selling my race roller version, it is full on race ready, but it is a race roller only. Have $300 worth of extra parts, and 5 lids for it. Over $1000 worth of stuff for $200.
Acer Racing Ceramic Nitride bearings, Big bore shocks, and Yannick shock towers are just a few of the included upgrades. PM me if your interested. I can send pics.
If you would rather buy a new RTR I would advise it to be one of the most race worthy ready to runs on the market.
