I always really liked the stock F103 for asphalt.. only upgrades were aluminium diff, shock and motor mount rest was bog stock.
EXO103 and F1R are night and day different designs. Cant really compare the two. EXO103 was developed way back when foam tires were the norm. F1R was designed for Shimizu rubbers.
