In an effort to continuously test and evolve our ruleset, we will be implementing a temporary rule change for the 2020 season regarding our power-to-weight calculation. Our NASA Rocky Mountain Chapter is creating a local rule addendum to their ST6 class, and this change allows us to align with those local addendums in order to be more appropriately placed among their run-groups and sessions. To calculate your vehicle’s new minimum weight please obtain your “average…

Andrew DeJesus, who has made zero modifications to his car since joining Front4, instead focusing entirely on driver improvement (setting new track records everywhere he goes), has now apparently developed Jedi powers. We got video proof of this at HPR, which immediately went viral on the Internet, being picked up by DriveTribe, Top Gear, and others!
"Andrew Becomes Famous!"We now have our own tire & gearing calculator, so that you can easily see the difference from tire, redline RPM, and gear ratio changes! Tire & Gearing Calculator
"Tire & Gearing Calculator"Yet another great race weekend with NASA Rocky Mountain! La Junta may not seem like a technical track, but its complex braking zones proved to be difficult to master, and very rewarding when you do. Andrew DeJesus found this out as he shattered our previous 1:00.852 track record with a 59.904 on Saturday, and then improved that to a 59.883 on Sunday! Saturday’s points race started with excitement as a car in another class tried…
"Return to La Junta (May, 2019)"The 2019 season is about to begin, and there are a few things to cover to make sure everyone is ready… All Competitors: Make sure you have a current dyno, and enter it on your Competitor Registration form on this website. Weights have been tweaked a little since 2018, so please see your Competitor Registration form or Driver Profile page, which will calculate your required minimum weight for 2019. Please be sure to review the…
"2019 Season Checklist"Attn Front4 Drivers: We’ve recently made some updates to the Front4 rules. Most of these are simple clarifications of existing rules, as well as proactively addressing future potential problems with certain builds. None of our existing cars are really affected by these changes, but we made them in an effort to keep our cars more equal and prevent someone from building a setup that has any notable major advantage. Please go to our Rules page…
"2019 Front4 Rules Announcement"At the final NASA event of the season, Chris Venturini beat his own previous Pueblo record, setting an even faster lap record for Front4 in his budget-built 1992 Acura Integra! Although the video says 1:48.907 based on GPS, the official transponder had him 12 milliseconds faster at a 1:48.895.
"Pueblo Lap Record Video"There are many engine choices available in Front4, and you have the flexibility to choose somewhere between low weight (and lower power) or high power (and higher weight). The current 2018 rules establish the following parameters: Engine Output = (Engine_WHP + Engine_TQ) / 2 Engine Output cannot exceed 160 Vehicle Minimum Weight (w/ driver) = Engine Output * 17 Vehicle Minimum Weight must be at least 2200 lbs Based on this, we know that anything…
"Engine Setup Strategy for Front4"Here’s our new 1:42.921 lap record at Hastings, which also became the new PTD class lap record for NASA Central. There’s definitely some more time left out there, as the alignment was way wrong for these tires, and there are a few places to drive a bit harder or better, but it’s a good start. Such an awesome track for our cars! Hopefully we’ll get the opportunity to race there again next year…
"Hastings Lap Record Video"Video from Weston and Hsun at PPIR Time Attack, August 5, 2018. 1st and 2nd place in FB class, driving Weston’s B20-powered ’95 Integra. Hsun earns himself a nice lead through the offset slalom, followed by Weston going in a bit too hot and blowing the hairpin on the banking. Assuming that the run was toast, Weston tries to use it to see just how fast he can take the final section, fully expecting to…
