|Part of||Custom Series Championship|
|Goal||Place 1st in the Grand Prix|
It is the fifth stage of the Championship and is composed of 6 Races. This track can be very difficult in some areas, specifically the Big Surf Grove [R] and Airport Terminal 1 & 2 [R] tracks, where traffic and layout can be really difficult to navigate unscathed.
This Grand Prix is notable for being one of the only two Custom Series Grand Prix to include cars outside of the Custom Series. In this case, the Japanese Muscle is an opponent despite not being classed as a custom vehicle. The only other event to share such an occurrence is the Heart Attack Grand Prix.
Upon completion of this Grand Prix, the fifth custom car, the Custom Roadster, is unlocked. This is the last car to be unlocked via Grand Prix in either championship.
This event is comprised of 6 Races:
|Crystal Summit Peak (R)|
|Freeway Dash (R)|
|Sunrise Valley Downtown (R)|
|Big Surf Grove (R)|
|Palm Bay Marina (R)|
|Airport Terminal 1 & 2 (R)|
- Upon winning the Grand Prix, the player is rewarded with a trophy.
- Palm Bay Heights (R) and Crystal Summit Lake (R) are unlocked for Single Race and Time Attack modes.
