Drift Week has become a huge name and part of drifting in North America, but some folks are still learning what it is. Drift Week is a cross-state adventure where you street drive your drift car to multiple tracks and then drift those tracks. For Drift Week 7, there were nine track days. You are not allowed a trailer or support vehicle once the adventure has started. You are, however, allowed to trailer to the first track and home from the last track. We opted to street drive the entire trip. 

A group of friends and I built a 1997 BMW M3 for the trip in a matter of weeks. The build was full of parts I felt were necessary to make the car reliable enough to do nine track days and over 4000 miles of street driving. 

One of the most important things to having a reliable car is keeping all the fluids maintained and sealed up, such as engine oil, power steering fluid, brake fluid and coolant/water. While thinking of what this car would need to be ready for the trip, I immediately thought of Chase Bays. I knew I needed reliable and high-quality products to manage my fluids and make it through this trip. These products included:

• Chase Bays Dual Piston Brake Booster Delete
• Chase Bays Power Steering Kit with Cooler
• Chase Bays Raised Inline Filler Neck (to delete that pesky expansion tank)
• Chase Bays Clutch Line
• Chase Bays Handbrake
• Chase Bays Handbrake Brake Line Kit
• Chase Bays Coolant Overflow
• Chase Bays Windshield Washer Reservoir
• Chase Bays Engine Oil Cooler
• Chase Bays Oil Catch Can

All of these products were super straightforward to install, which was great given our timeline of three weeks to complete the car and hit the road.

Our Drift Week trip started in Boise, Idaho, with our first destination being Tucson, Arizona. After two successful days at Musselman Honda Circuit, we headed to Southern California. There, we had five total track days at three different tracks. The last leg took us to Tooele, Utah, for the final two track days at Utah Motorsports Campus. Then, it was time to return home. Sounds simple enough, right?

Well, you can prep a car as much as possible, but that is a lot of driving and track days piled up next to each other. As anticipated, my fluid systems were flawless, and the brakes were insanely consistent on the track and the thousands of miles spent street driving. I could hardly remember what the boosted setup felt like because I loved the manual brakes so much. The power steering system stayed cool and consistent while pushing the car to its limits. 

Thanks to the Chase Bays Oil Cooler, the engine oil temperature was easily managed throughout the trip. Removing that troublesome BMW expansion tank was helpful. We remedied this by using the Chase Bays Upper Water Neck and welding it to the thermostat housing. Then we installed the overflow tank for the venting side of the system. We still were struck with a challenge as the 225k mile head gasket decided it had finally had enough. The compression ring between cylinders 5 and 6 had failed and caused a misfire. 

This is where another aspect of Drift Week came into play—community. We were in an Airbnb with some great folks, including Kevin and Ryan from Canada. We hardly knew them before the trip, but this adventure was not only track days and drifting but meeting new friends and building awesome relationships with those people through drifting! We hitched a ride with them and gathered all the parts to perform a head gasket repair in the garage of our Victorville Airbnb. We saw some amazing places such as Pelican Parts, Hoonigan, and Moon Eyes. Ultimately, we fixed the car. We missed a few track days due to it, but we were back at it before long.

Another thing that helped this repair be so much simpler was the simplicity of the Chase Bays parts we had installed. The Motorsport Dual Piston Manual Brake made pulling the intake manifold a breeze since the brake booster was no longer there. The cooling system was nice and simple since the expansion tank was now gone. So many aspects of the engine bay had been simplified thanks to the Chase Bays products, which made working in the bay much easier.

Once we completed the Southern California tracks, we headed up north to Utah. There, we hit a bunch of snow on the final track days. The brakes shined here as they worked just as well in the frigid cold as in the warmer southern weather (we missed the California snow track day). I could control the car consistently with left foot braking thanks to the easy-to-manage manual brakes provided by the DBBE. I could throw big entries in the wet and use the foot brake to slow the car without just locking up the brakes or jabbing them as inconsistently as you can with a vacuum-assisted brake setup.

In conclusion, we built an amazing car that was an absolute joy to drive, even with some really old high-mile bones. The parts from Chase Bays helped keep the car cool and consistent throughout the entire 4000+ road miles and 7 track days. Not a bad way to spend a week, if I do say so myself.

I would argue that the most talked about topic when it comes to manual brakes, is what do they feel like? There are a few variables that determine this, but in short, they feel great. A lot of times people will state the pedal is to hard, or it feels like the car wont stop.  If you are feeling this, something is wrong. A proper manual brake setup (matched ratio with master cylinder bore size, good pad compound, and Front / Rear Bias Adjustment) will net a great pedal feel with the exact same braking every time.

The pedal will feel a little more firm than a brake booster variant, but not in a negative way. The brake boosted variants always have a lot more travel than a manual style and will be significantly more sensitive to input.  So over the years, people have the muscle memory for that and think that is normal.  A properly sorted manual braking system will only feel slightly stiffer than the booster version, in a good way.

The modulation of max braking just before lockup is where manual brakes really thrive. We call it the 90-99% zone. Finding the exact level of leg pressure to get that exact threshold is just not possible with power brakes, as stated above they’re too sensitive which create inconsistency. So YES the 90-99% zone is a little more leg effort than power brakes but that’s what makes it so great. This is massively to our benefit in finding the right leg force every time. Even on a daily driver, it will feel more consistent and positive than the alternative.

In summary, properly sorted manual brakes are easy to drive on the track and street. There are many benefits as we have discussed previously, to a manual braking setup.  You will be very pleased with the drivability and on track performance from a manual braking setup.

The fact is, manual brakes are on the fastest road race cars in the world. From IMSA to F1. But how is this possible!? You read online it was like trying to put your foot through a brick wall! How exactly can manual brakes improve lap times?

The major point I drive home to all those that I coach; consistency. If you can be a consistent driver and make decisions with intention rather than reaction, you are setting yourself up for success. So to be fast we have to be consistent drivers. We are the throttle, brake, and steering actuators on a car.

That means we need those things to be consistent. Throttle is generally consistent (unless you get into DBW with throttle shaping but thats not for this convo). Steering can be consistent if it is either manual, electronic, or properly cooled and managed hydraulic power steering. We also assume our suspension setup is correct and not out of alignment, producing consistency there too.

Braking consistency, this is the last step. I have and will always stand by the comment: braking is the hardest thing to do to extract a lap. How you get on the brakes, how long you are on them, when you release them, the time frame you release them in coupled with steering angle. That's hard stuff.

There is a reason why you see Miatas at the track beating up Corvettes and Porsches. Of course there is the driver mod, but doesn't that mean the Miata driver is utilizing the brakes more effectively? Because they certainly are in a lesser power car.

Now here's how we pull it off. I spoke of consistency earlier, we need to be proactive not reactive with everything we do. In order to accomplish this, we have to have a consistent pedal. The manual brake is the surest way to accomplish this. In a prior blog, I used the analogy of pressure from your finger to a wall. Here is a refresher, if I ask you to place your finger on a wall and give me a little pressure, you can do that, if I ask for a lot of pressure you can do that as well. Just because the wall didn't move doesn't mean there was no pressure applied to the wall.

So with a more firm pedal we can produce brake pressure that is consistent and predictable. With this you will be able to repeat results each lap because the pedal feels the same way. You will have the confidence that heading into 10a at Road Atlanta, that your brake pedal will feel exactly the same each time, thus allowing you to play with brake zone depth and releases. As we stated before, its also important how and when you release the brake pressure as well. Now that we know what the initial force feels like and how quickly the car decelerates. This will allow us to properly set up braking zones.

In conclusion, the opportunity list looks like this.

1. Consistent pedal feel (assuming proper setup, no air in the system, or overheated brakes)
2. Allows us to easily explore gains and loses in the braking zone by playing with brake timing and release.
3. Trains us to be proactive rather than reactive to our pedal. Power brakes inconsistency in pedal feel cause slight hesitation. This lowers driver confidence thus hurts lap times.

This is an example of a power assisted brake. Notice how the pressure is inconsistent? This could be due to the fact that the pedal moves to much and the driver "pumps" the pedal trying to get it to slow down.

This is an example of a manual brake trace. Notice how the initial braking force is high and slowly tapers off. This is what the brake trace should look like, this eliminates braking distance thus resulting in faster lap times.



These are all dual master setups with balance bars. They are great, but it’s not exactly in most of the grassroots/amateur motorsports worlds budget. Enter the Chase Bays Dual Piston Brake Booster Delete with Bolt-On 6:1 Pedal Ratio. This system allows you to receive many benefits from the manual brakes, without the fab/cost of an expensive system. Having now driven with this system, and won our first race with one, I can confidently say this is your ticket to faster laps. We took someone with zero experience with a manual brake, installed this system on his car, he immediately went faster. The only piece of advice I would give is to pump your brakes before the braking zones. Not a large amount of pressure, maybe 10%...just enough to reset the pads. Unless you have anti-knock back springs you need to do this. The power brakes give off the false sense of not needing to do this. I can assure you, you need to. When you strike curbs or load a side, the pads will push back a little. Thus the pedal will travel further making it seem like you have a long pedal. This happens on manual or power brakes. The power brakes just mask this a little bit more. By giving the brakes a small tap with your left foot pre-turn, you will have knocked the pads back into place.
