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"Posts
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…
"PPIR Time Attack 1st & 2nd Place Video – 8/5/2018"Just how fast can a Front4 car go at High Plains Raceway? That’s what Dan had asked me prior to this event… I responded with an optimistic guess of 2:10, not knowing if we could really pull that off with our 4 cylinder engines and 100-200 treadwear tires. As it turns out, I didn’t give us enough credit… By the end of the weekend, half of our racers would hit that target, with two of…
"Results from HPR (July, 2018)"Integra LS transmissions are the cheap and plentiful option for Honda B-Series drivetrains. Their long gearing usually means less shifts on the race track, but could we go faster with different gearing? Well, that will depend on the track, and the situations you find yourself in during a race… A Quick Primer Your transmission multiplies engine torque to give you far more torque to turn the wheels. It’s based on your gear ratios: if your…
"Integra & Honda B-Series Transmission Gearing"PPIR was a battle of wits, heat, and endurance. We arrived with much more race-ready cars than the rush-jobs we had at La Junta, only to find ourselves fighting a number of different mechanical surprises throughout the weekend, but we stuck it out, worked on cars and beers late into the night, and ended up having some close and hard-fought race battles. It was a fun and very memorable weekend for sure! Saturday looked to…
"Results from NASA PPIR (June, 2018)"Did you know that there are actually two Koni Yellow models? Most Yellows are the 8041 Sport model, but racers often want a shock that can handle even higher spring rates and lower drops, which is where the 8041 Race shock comes in. While the Sports are said to max out around at 400-600 lbs/in spring rates, depending on who you talk to, their Race shocks have the popular SPSS3 valving and can do up…
"Koni Yellow Sport vs Race"We all love racing and track day videos, but setting up cameras in our race cars is usually a last-minute rush job… Too many other things to do first! Sometimes we get lucky and happen to choose a good camera angle and settings, but more often we end up not seeing all of the action because our camera setup wasn’t optimal. So, after years of many of us learning the hard way and missing out…
