Trackspec's K24 Exige- Brake Bias Cage

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.

P2 and P5 in ST4 for our E46 M3 on the Yokohama ...

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.

Last 111, First Street Legal K20 Swap? (Part 2)

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.

Trackspec's K24 Exige- Global Time Attack

A few months ago, we decided to register for this year’s 2021 Global Time Attack and Super Lap Battle Finals at Buttonwillow. The Exige wasn’t built for time attack, but we thought it would be a fun place to compete and see how capable the Lotus with a K-series really is; even if it is heavily outgunned in its class (because of the rule set, the car falls into Limited, a class that normally sees cars with forced induction engine setups making well over 600whp). We decided to set our own goal of a sub 1:50 lap, which may be the first naturally aspirated Elige to do so. The best time this car had done previously at Buttonwillow 13CW was a 1:51.7 on Falken RT660s.

One-Two Finish at the 2020 NASA Pro Racing Season Finale

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.

Trackspec's Exige S240 Project: Part 10, K24 Swap (2)

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..
