Reduce brake pressure so you only have a subtle hint of this. However, threshold braking is much easier to achieve in ABS equipped cars, as you get additional feedback – when engaged the ABS causes significant vibration which can be felt through the wheel with force feedback. Correctly carried out threshold braking is still more efficient, as ABS tends to work in a pulsating manner meaning the tyres lock up very briefly, reducing the braking performance and causing additional tire wear and heat. Whilst ABS prevents locking of the wheels under heavy braking – especially when turning at the same time – it shouldn’t be relied on.

Many modern race cars such as the GT3 class now feature driver aids such as traction control and ABS.

Drivers tend to brake with an initial force which causes the tyres lock up at the end of the braking zone, failing to take full advantage of the extra grip early on. Turn 1 at COTA with Martin Krönke in the MP4-30:Ī common mistake in racing downforce cars is not braking hard enough initially. How this typically works in practice: Slam the brakes to reach threshold braking quickly, then “bleed” off the brakes at the same rate as the car slows down and the downforce comes off. This of course means the required threshold braking pressure will decrease in connection with your speed. When you start braking therefore, your speed is obviously greater than when you finish, and the grip level in turn decreases as you continue to brake. At high speed the car will produce more downforce and therefore the tires will have more grip when compared to travelling at low speed. VRS app telemetry braking trace before T5 at Okayama in the MX-5:įundamentally the same rules apply to downforce cars, but it’s key to understand that the level of grip is speed-dependent. It’ll be obvious in iRacing when you’ve locked up, the tires will screech, the car won’t turn in the case of a front lock up, and you may see visible smoke. This is therefore something which can be trained into your muscle memory over repetition. The required pressure will be consistent and repeatable regardless of speed assuming tire wear is discounted and the circuit is flat. Learn how the tires sound just before they lock up, and avoid braking harder than that (to help, you can raise the tire volume in the options menu). It’s also possible (but more difficult) to feel changes in load through force feedback and rpm changes in the case of rear locking. Firstly it’s a matter of listening to the tires, or in the case of open wheelers, visually seeing them lock up. With the above in mind, there are a couple of sources for feedback which can help out in the “feel” department. From this moment on, reaching threshold braking is a case of delicate modulation, and very much a feel thing, requiring practice. This is when the wheels have the most energy and are least likely to lock up. Even if you drive a downforce car, read the non-downforce section first.ĭon’t be afraid to brake too hard when you first hit the pedal from high speed.
We’ll divide braking technique up into non-downforce cars, such as the Mazda MX-5, Skip Barber, Porsche/RUF and Lotus 49, and downforce cars, such as the Formula Renault 2.0, the HPD, and the McLaren MP4-30. It’s the brake pressure required to reach the point at which the tires are just on the edge of locking up, and no more. Achieving this requires you to exploit nearly 100% of the available grip from the tires in a straight line. To brake as late as possible, you want to reduce the time spent slowing the car to a minimum. The second is more subtle, which is that brakes offer a method of controlling weight transfer and balance from corner entry to apex.
The first is pretty obvious: to slow the car down.
