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…"2020 Weight Calculation"
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"
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"
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"
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…"Race Car Video Setup"
A few tips for heading out to a road course track day… Prepare Yourself: Have the right info. Different organizations run track events differently, so make sure you’re aware of their rules, drivers meeting time / location, and other expectations. Seriously, don’t miss the drivers meeting or any required “download” / classroom sessions. Show up early. You don’t want to be “that guy” or miss out on track time. Have a suitable helmet and…"Track Day Prep Tips"
Instead of replacing an Integra’s engine with another B18 (1.8L), several of us have opted for a B20 (2.0L) from the first generation Honda CR-V. These engines tend to be easier to find in good condition, are potentially less expensive, and of course they make more power and torque due to being larger displacement. We’ve learned a few things along the way, and hope that this will save you some time and frustration: Basic…"Honda B20 Engine Info & Tips"
