ARC is a decent car with great price. people race ARC R10 2013 in Taiwan. It is reasonable stronger than most Japanese car and handle very well out if box. the parts are cheap to buy and suspension arms are interchangeable with Xray for the ease of parts. highly recommended. they also have part to convert it into 200mm with VDS shell to turn it into a beast that capable of chewing an 1/8th if the track isn't super large.
personally I race Schumacher which is considered the most durable car at my local track. It run well and is an eye catcher. although a bit pricey but the quality is unmatched. the alu. parts from my Mi4 and Mi5 never bent a bit even when I crushes so bad that destroy my chassis and shock tower while my old T4 bent in lesser crush.
