Rules & Regulations Interpretation
02.51
| 00:00 | The rules and regulations of a race series are instrumental in defining the size, shape, and aerodynamic intent of the devices we're using on a car, so it's important to understand what the consequences are of certain rules and how we can get the most from them. |
| 00:14 | A large amount of aero performance will come from maximizing our use of the rules, so we should read them multiple times and consider all the different parts of them that can be exploited. |
| 00:24 | In many series, people haven't made full use of the rules, because they haven't properly read or understood what's available to them. |
| 00:31 | If the rules allow us to put aero in a space that others aren't using, then we should consider it. |
| 00:36 | If the rules allow us to run a flat floor, we should strive to get one fitted. |
| 00:41 | If we're allowed a two-element rear wing, 99% of the time we should run it. |
| 00:46 | Rule boxes or legality boxes are what we call the volumes that are defined by the rules as locations where we can put aerodynamic devices. |
| 00:55 | We should always be looking to maximize our rules and ride-height boxes wherever possible to achieve the best result. |
| 01:01 | Club level rules typically focus on front splitter size and shape, rear wing size and position, as well as number of elements. |
| 01:09 | On the front end, this usually means dimension from the bumper, following the shape of the car, or an overall sizing box. |
| 01:17 | Generally speaking, for most rule sets, we want to maximize the front splitter area that the rules give us, and then balance it out with sufficient rear wing. |
| 01:25 | However, some rule sets limit the size of our rear wing quite heavily, and in these cases we may need to de -power the front splitter to compensate for a small rear wing. |
| 01:35 | For the rear wing, no matter what the rule set, we always want to maximize the span, which is the width of the wing from end plate to end plate. |
| 01:43 | Higher span wings are more efficient than lower span wings, producing less drag for the same amount of downforce. |
| 01:49 | Once we've maximized the span, we can then worry about the specifics of wing selection, which we'll be diving into later in the course. |
| 01:57 | Generally speaking, for most rulesets though, we want a high-level of adjustability in the wing and we want to use most of the rear-woods legality box available. |
| 02:05 | Most reputable manufacturers will be able to guide a customer on what size wing will be best suited to balance their front aero. |
| 02:13 | Let's quickly summarize the key points found in this module. |
| 02:16 | Race series rules and regulations greatly influence the size, shape, and aerodynamic capabilities of a car, so fully understanding and exploiting these rules is crucial for maximizing performance. |
| 02:28 | Many racers miss out on potential advantages by not fully utilizing the allowable space or features, such as fitting a flat floor or using a two-element rear wing. |
| 02:38 | Key strategies include maximizing front splitter area, rear wing span, and ensuring sufficient adjustability while balancing front and rear aero based on the rule set. |
