Tiantian Chengzhang Ji 2nd Season (Dub)

Based on the manga by Tetsuhiro Koshita, Bakusou Kyoudai Let's & Go!! has two main seasons evolving around the Go brothers and the TRF Victorys. The third season, Bakusou Kyoudai Let's & Go!! MAX evolves more around two new main characters, but the primary idea is the same... Racing! Let's & Go!! focuses on Retsu and Go Seiba, two young brothers who receive racing cars called "Mini 4WD" by Dr. Tsuchia. From there on, the series portraits those two boys, training and customizing parts to later on participate on Japans Cup, where all of Japan's racers enter to be the best of the best!

Mechadock is a powerful race car obtained from a simple economy car, which is able to race on any ground.

Every five years, an exhilarating race called Redline is held, and the universe's most anticipated competition has only one rule: that there are none. Racers are pushed to their absolute limit—a feeling that daredevil driver JP knows all too well. Having just qualified to participate in Redline, he is eager to battle against the other highly skilled drivers, particularly the beautiful rising star and the only other human that qualified, Sonoshee McLaren. But this year's Redline may be far more dangerous than usual—it has been announced to take place on the planet Roboworld with its trigger-happy military and criminals who look to turn the race to their own advantage. However, the potential danger doesn't stop the racers; in fact, it only adds to the thrill. Relying solely on his vehicle's speed, JP prepares for the event to come, aiming to take first place in the biggest race of his life. [Written by MAL Rewrite]
