Grudge/Test-N-Tune:
Grudge/test-n-tune class is a no payout class that is focused on having fun! This class is perfect for those who are looking for a Saturday night fun-run style class just like they have at their home track. Team up against a friend or race against yourself and the clock. Perhaps your car wouldn’t be competitive in any other class. Maybe you’re learning to drive a newly developed setup. This class is ideal for any of those scenarios. The class will be run throughout the entire weekend and is only available to competitors that are not competing in another class during the event. The only exception would be for competitors that are running True Street on Saturday. These will be able to enjoy Test-N-Tune on Sunday.
Class Rules: Other than having an LS or current gen LT engine, there are no class rules or limitations to this class. All NHRA safety regulations for speed DO APPLY.
True Street:
True Street is a heads up class designed for fast street cars. All entries will participate in a thirty-mile cruise, and then head back to LVMS to make some passes down the racetrack.

Late Model Heads-Up is one of the most exciting classes at LS Fest West. This class will feature the quickest LS, and Gen V LT powered cars in recent production. This class is meant to give Late Model owners a place to showcase their cars and builds. The rules are simple but effective. Entry must be 2008 and newer, and LS or Gen V LT powered, run on 15 inch or greater diameter wheel and 235 mm section width or greater DOT approved tire. This is an all run, qualified field with a touch of grudge action. The “qualifying sheet” will be used for two purposes. First, the bragging rights of being #1 Qualifier and second to determine a potential bye run, for first round of eliminations. A “PRO” style ladder will be used for eliminations until we are at 8 cars or less. From that point forward when called to the lanes, all remaining 8 contestants will draw a numbered chip and return to their vehicle. The contestant that draws the number one chip will have first choice as to who he or she would like to race. #1 can choose to race #2, and then #3 would have next choice until all contestants remaining have been chosen. Each corresponding round going forward would employ the same process. When called, report to staging lanes, draw chips, choose your competitor. This will make for some very exciting on and off-track action.
