Street Outlaws: Memphis - Season 4

Fresh off their huge win against NOLA, JJ Da Boss and the MSO hit the streets after getting called out by Quinn Shireman and his team. Quinn has a big mouth and the fast cars to back it up, forcing the MSO to go all hands on deck for a win.

Race night against the Kentucky racers continues with JJ throwing a curveball and Kentucky falling behind. A face-to-face confrontation emerges on the course and tempers are boiling out of control but MSO is determined to prove why they're the best.

Race night gets rowdy when Memphis welcomes a new racing group from Virginia. The newcomers talk a big game but run out of cars after only a few races, leaving Molly and Ole Heavy without a race until Virginia can fix their cars and return.

The Memphis family loads up their cars and heads to Battlefield Dragway in Mississippi for one of JJ's famous arm-drop competitions. Thirty-five small-tire-car racers begin round one in this exclusive event, but only one will take home the grand prize.

JJ gets a callout from Chris Bromley and his Fox-Body Mustang drivers from Massachusetts. Chelsea is excited to race her new car and Molly is out for redemption but technical difficulties make it hard for the MSO to prove they can outrun any Mustang.

JJ invites 32 racers from all over the country to compete in Street Wars -- a winner-take all event with a grand prize of $10,000. The competition is open to all, even those with pro-mods, so the MSO must focus if they want a shot at the prize.

MSO gets called out by Ronnie Pace and his team from Texas. It's not long before Memphis begins feeling the heat up against Ronnie's Texas-sized mouth and deep pockets, leaving it up to the more inexperienced racers to bring the MSO back into the black.

Tricia and JJ both have chances to redeem themselves while Memphis continues to struggle against Texas. The competition is more intense than ever and one wrong move could mean it's game over for the Memphis crew.

The MSO heads to St. Louis to race the slick streets against a team of even slicker racers led by Dynamite Dave. Memphis came out on top the last time these teams faced off, now the St. Louis crew is ready to even the score on their home turf.

After a grueling night against St. Louis, MSO gets a callout from some Oklahoma Racers who want to challenge Memphis on the same sketchy street. JJ and the crew aren't ready to back down but they must rally to make staying out another night worthwhile.

As their battle with Chicago approaches, the MSO scrambles to fix Heifer after losing her to a fender bender. JJ finds a '65 Malibu they can use but Chicago is stacked with fast cars and street sense, so running an unknown may be out of the question.

MSO prepares to face off against some local racers led by the fast-talking Tony Yeager. Tensions are high thanks to MSO's history with their competition that includes some unfinished business between Mustang Mike, Anthony Smith and two of the locals.

The MSO steps up to the challenge after larger-than-life Chris Block challenges them to switch to small tires and compete against South Carolina. With little time to prepare, Memphis must quickly adapt or risk losing to Block's mind games.

The MSO starts the season off with a big plan to only race on small tires. Not everyone on the team has small-tire experience, so Memphis will have to work together to overcome a challenge from Tim White and his small-tire killers from Illinois.

Just when the MSO thought they were all finished with their small-tire race against Illinois, Tim White challenges JJ to another night of racing. This time, however, Tim has a surprise in store -- the Illinois racers are now rolling on big tires.

Quinn Shireman, longtime rival of the MSO, invites the team to Kentucky for an arm-drop event like no other. Quinn bets JJ that the MSO can't win and brings with him a team of heavy hitters to make sure no one from Memphis has a shot at the cash prize.

JJ's Arm Drop event in Kentucky continues and the MSO is still struggling to knock out Quinn's hired guns. The stakes are high and if Memphis cannot manage to win the entire event, they'll lose their side bet with Quinn and go home in the red.

Tony Yeager and Whitfield roll into town with a group of local Donk-driving racers ready to call JJ out. The familiar foes have a plan to get inside JJ's head by going after the girls and hopefully pull out a win against the MSO.

Now that his team is on small tires, JJ puts them to the test by inviting the country's best small-tire racers to Memphis for a race with a $16,000 pot. Big-name foes are in town so it's up to the MSO's heavy hitters to bring home a win.

Round two of JJ's $16,000 small-tire race kicks off and only half of the MSO is still in the competition. The team is behind, but they're ready to fight for every win, no matter what it takes ... even if they have to race each other.

Nashville street racers call out the MSO to see who really runs the streets of Tennessee. Memphis never backs down from a challenge, but with Ziptie out of commission and Heifer having trouble, the team must really step up if they want to win.

The MSO is surprised when a group of racers claiming to be from Delaware turns out to be a team of racers from all over America. This all-star group is made of familiar faces who have suffered losses at the hands of the MSO and are now hungry for revenge.

The MSO continues their battle against an all-star group of racers out to avenge past losses on the streets of Memphis. Tonight, however, includes a few new racers who have defeated the MSO including Jason Copeland, Brent Self and their Camaros.

The MSO family loads up the hot rods and heads to Vegas to meet up with King Donnie and a group of West Coast racers. Molly and Chelsea step up to take on the challenge but the roads are unusually slick, making it a struggle to bring home a payday.

JJ calls up a group of racers who have all beaten the MSO before and challenges them all to a rematch. While it may be the biggest challenge Memphis has ever faced, pulling out a win will prove the MSO is the fastest small-tire racers in the game.

The second night of racing against teams that have beaten the MSO continues, only this time Dynamite Dave rolls in with some new heavy hitters from Missouri. After being down from the first night, Memphis can't afford to let it happen again.
