Go kart school and equipment shop in bangkok

Hi guys....

I have a son, almost 8 yo, and he's very interested to be a go kart racer. When we went back to our home country for long vacation last july-august, he had go kart practiced and under training by professional racer. What I'd like to know here...where can I buy go kart equipment such as helmet, neck n body protector, shoes, glove, n also go kart suits for kids? Is there any go kart school in Bangkok also?

I went to RCA also....they have free training for kids but too bad it only on Thursday night. Impossible for my son to take that training on weekdays.

I hope somebody here can help me to give some information.
