How to Choose the Right Aftermarket Brake Pads for a Lotus Elise for Track Use?

March 22, 2024

When it comes to selecting aftermarket brake pads for track use with a Lotus Elise, there are a few key things to bear in mind. This process is not just about picking the first thing you come across. It requires careful consideration of aspects such as brake performance, pad materials, wear rate, and friction levels.

Today, we’ll delve into this topic, providing a comprehensive guide to assist you in making an informed decision. We’ll discuss both track and street use and help understand the importance of bias in braking systems.

Understanding Brake Basics

Before we get into the specifics concerning the Lotus Elise, it’s crucial to understand the basic principles of brakes and brake pads.

Brakes are the components in your vehicle that create friction to slow down or stop your car. They do so by clamping onto the brake discs, which are connected to the wheels. Brake pads, on the other hand, are the parts of the brake system that come into direct contact with the brake disc. The friction generated between the brake disc and the brake pads is what slows down your car.

When selecting aftermarket brake pads for your Lotus Elise, especially for track use, you need to focus on the amount of friction they can generate, how quickly they can do so, and how well they can manage heat.

Choosing Brake Pads For Track Use

There is a big difference between street and track use for brake pads. When racing on a track, the brakes will be used more aggressively and will reach higher temperatures than under normal street driving conditions.

Performance brake pads for track use, therefore, need to have a compound that can withstand high temperatures without losing friction. The pad material you choose for track use should offer high friction levels while also providing consistent performance over a wide range of temperatures.

For a Lotus Elise, pads with a semi-metallic or fully metallic compound like carbon-ceramic will be ideal. These offer superior high-temperature performance, although they may wear out faster and be more prone to brake noise.

Front and Rear Brake Pad Selection

It’s not enough to consider the brake pad’s material and compound. You also need to think about the bias between the front and rear brakes.

In a Lotus Elise, as with most cars, the front brakes do most of the work. This is because when you brake, the car’s weight shifts forward, putting more load on the front brakes. Therefore, the front brake pads need to be higher-performing than the rear ones.

For track use, you should consider a high-performance compound for the front brakes, and a slightly less aggressive compound for the rear. This will ensure optimal brake bias and prevent the rear brakes from locking up during aggressive braking maneuvers on the racetrack.

Pad Wear and Replacement

Lastly, it’s crucial to know that brake pads for track use will wear out more quickly than those designed for street use. This is because they’re subjected to much higher temperatures and more aggressive use.

To ensure you always have effective brakes, you’ll need to check the pads regularly and replace them when needed. The wear rate will vary depending on the pad material and your driving style, but generally, you should be ready to replace the pads after every few track sessions.

While this might sound like a hassle, remember that your brakes are one of the most critical safety components in your car. Regular inspection and timely replacement of worn pads can make a significant difference in your racing performance and safety.

Concluding Thoughts

Choosing the right aftermarket brake pads for track use in a Lotus Elise involves a combination of understanding the basic principles of brakes, knowing the difference between street and track use for brake pads, considering brake bias, and keeping an eye on pad wear. By considering all these factors, you can ensure you have a braking system that performs excellently on the track, keeping you safe and helping you shave seconds off your lap times.

Remember, while cost is certainly a consideration, don’t let it be the only factor in your decision-making process. The brake pads are an integral part of your car’s safety system, and investing in high-quality pads can make a significant difference in your track day performance and enjoyment.

Important Considerations for Day Spec Brake Pads

When discussing day spec brake pads for a Lotus Elise, it’s essential to mention the initial bite, brake fluid, and the balance of front and rear brake pads.

Initial bite refers to the immediate response of the brake pads when pressure is applied to the brake pedal. Pads with a high initial bite respond quickly and provide strong braking force from the start. This feature is important on the track, where braking requirements can change rapidly from moment to moment. For a Lotus Elise, it would be beneficial to choose pads that have a high initial bite for track use.

One often overlooked component in the brake system is the brake fluid. Brake fluid plays a crucial role in transmitting the force from your foot on the pedal to the brake pads. On track days, the brake fluid can heat up due to the aggressive use of the brakes. Therefore, it’s essential to use a high-quality brake fluid that can handle these high temperatures without boiling.

The balance of front and rear brake pads also plays a significant role in the overall performance of your brakes. As we already know, the front brakes do most of the work in a Lotus Elise. However, the rear brakes are not to be neglected. They help to maintain balance and stability, especially during hard braking and cornering. As such, choosing the right pads for the rear is just as important as for the front.

The Role of High Friction and Friction Material

The effectiveness of a brake pad is largely determined by the friction it creates. Therefore, high friction is a critical factor to consider when choosing brake pads for track use. High friction brake pads generate a lot of stopping power, which is necessary for high-speed track driving.

The friction material of the brake pad plays a significant role in determining the level of friction it can produce. Semi-metallic and fully metallic materials, such as carbon-ceramic, are known for their high friction levels. These materials are very resistant to high temperatures, making them ideal for track use. However, they may wear out faster and be noisy compared to other materials.

One popular choice for Lotus Elise owners is the EBC Yellowstuff brake pads. These pads have a high friction coefficient, perform well at high temperatures, and have a reasonable wear rate.

Concluding Remarks

Choosing the right aftermarket brake pads for your Lotus Elise for track days involves a careful consideration of several factors. Understanding the basics of how brakes work, the difference between street and track use, the importance of brake bias and pad wear, and the specifics of day spec brake pads, is crucial.

Don’t forget about the importance of the initial bite, quality of the brake fluid, and the balance of front and rear brake pads. Also, the type of friction material and its ability to generate high friction levels will significantly affect your braking performance on the track.

Remember that while cost is a factor, the consequences of not having the right brake pads can be far more costly. Your safety on the track is paramount, so invest wisely in high-quality brake pads and enjoy your track days with confidence.
