About two years ago, we decided to run a 15/17” wheel stagger for more tire selection, and in doing so, we had to install smaller front calipers (More detail on that here). The Cup brakes that our S240 came with were too big for 15” wheels. We were able to get a few 15” wheels to fit over them, but it required running some large wheel spacers. The set up we decided on were the AP Radical front calipers and the OEM 2 Pot calipers in the rear. Since the changes, the brakes never felt as good as the stock set up. The larger calipers require more fluid volume, and with the stock master cylinder, that meant the pedal had more travel and felt softer. We also noticed more ABS “ice mode”, which could be related to the change in brake bias and front to rear tire diameter.
I am thrilled to announce the return of Toyo Tires to our race program for the 2023 and 2024 seasons. I have had the pleasure of working with Toyo for many years previously, and this partnership renewal marks a commitment on both sides for shared success.
You’ve probably already seen the results online, 3rd in class (E1) and 9th overall. But what you don’t know are all of the details, the drama, the trials and tribulations and the blood, sweat, and tears that went into this past weekend. Fortunately, that’s what this blog is for…so please, read on.
This year seems to be just flying by. We last raced at the end of March, and since then the team has been busy with a wide variety of cool projects at the shop. Personally, my calendar has been filled with work, travel, and everything in between. One event in particular that transpired during this time was the official launch of the Yokohama A055 tire.
Before doing anything K-swap related to the new chassis, we started by transferring parts over from the original tub to the new one. Since this was a low mileage car, it wasn’t difficult selling the drivetrain. Timing worked out perfectly as there was another Elise in our shop needing a motor due to a failure.
With the 25 Hours of Thunderhill postponed to 2021 (thanks, COVID) the final race weekend of the year took place at Buttonwillow in the form of a double header, Super Touring sprint racing and a 3 hour and 15 minute night endurance race as part of the Western Racing Endurance Racing Championships. We were able to use the month of September to properly prep both the Lotus Exige and the E36 BMW M3.
We went into the month of August feeling excited for two reasons. First, our K24 swap was finally complete on the Lotus and after a solid shakedown at Laguna Seca in late July by Graham and Tom -- it was finally ready for wheel-to-wheel action. Second, we would have 2 race weekends take place relatively close to each other, August 1st and 2nd at Thunderhill and then August 22nd and 23rd at Sonoma.
In part two of the K24 swap, we were left waiting for the header to arrive. We ordered a Hytech 4-2-1 header specifically made for this swap, which took a little over a month to get, but was well worth the wait! It fit perfectly. Other than trimming the J-pipe to length it needs no modification to fit any muffler designed for this chassis. Once fitted, all we had to do was make an extension harness for the wideband o2 sensor.
The first race of the 2020 season feels like a lifetime ago...and not because it was way back in February, but because the world as we know it has changed dramatically over the past 15 weeks. COVID-19 caused just about everything to shut down...businesses, offices, parks, restaurants, schools, and what can best be described as a “normal way of life.”
When we left off in part one of the K24 swap, we had the engine in the car and started getting things connected. Although it seemed like it was close to being done, there was quite a bit left to do. We decided to keep the factory dual oil coolers. This may change in the future, but we wanted to make sure the temps were stable even on extremely hot days. Moving along on the track is one thing, but following closely behind another car in “dirty air” and it can get hot pretty quickly. Because these cars are known to over cool engine oil, we installed a thermostatic sandwich plate with a 200F thermostat to help maintain proper temps.
If you grew up in the 90s and were into cars, then you’ve heard of the Honda B-series engine and how amazing it was. It was the “hot rod” engine of its time and my gateway into modifying cars. The planning, researching, parts sourcing, building, and then seeing how it improved the car’s performance is what got me hooked. In the early 2000’s, Honda came out with something even better..
In Part 8, we were waiting on a driver net before we could have the tech inspection done. The Schroth net with the new quick release mechanism that we originally ordered was still undergoing testing and its availability was severely delayed. So, we went with a equally good option- Safecraft.
We love the start of every race season because it represents new possibilities. In winter of 2019, we decided that 2020 is going to be a year where we’ll be more focused on endurance racing. While we love the NASA Super Touring (sprint racing) series, we realized we enjoy enduros even more. As a team, we are aiming to win (our class), podium, or at the very least finish the 25 Hours of Thunderhill with my E36 BMW M3, “Heidi.” So, that’s what we’ve set out to do.
With a year of rebuilding and developing the Exige behind us, we were excited to begin our “winter project,” the roll cage. When the car came back from the last track event of the year (a very wet Laguna day), we gave it a good wash inside and out before getting into it. We also had to do some homework and make sure that what we build is safe and legal for the the local sanctioning bodies we plan to race with. We followed NASA’s Club Codes and Regulations handbook as a guide.
