When tracking a car with a high performance suspension and R compound tires will often overload the OEM eccentric adjuster causing it to slip. This is especially true when you hit racing curbs at high speed on a track day.  

When you install our rear toe link adjusters you no longer need the factory eccentric adjuster. This provides the opportunity to lock those adjusters so the alignment will stay put when driving on the track. We highly recommend this option when purchasing our toe link kit if you are going to partake in track days. 

⚠️ This kit ONLY works in conjunction with our Toe Link Kit, CBF82-3123 and cannot be used with stock toe links!

Emissions Legality:

Let us address the topic of removing the catalyst, commonly achieved through the utilization of downpipes. Our rigorous testing regimen involved conducting consecutive dyno runs with and without the catalyst, and the observed power gain was significantly smaller than commonly touted, typically around 11 HP. Nevertheless, it is important to acknowledge our shared responsibility towards environmental preservation, as clean air is vital to our well-being. Furthermore, obtaining the necessary emissions certifications without a catalyst is a daunting task and, from a legal standpoint, it is considered an infringement.

The Stage 1 Power package is safe and powerful. Combining the latest heat exchanger and software technology. CarBahn’s Heat exchanger increases OEM heat exchanger capacity by 40%! This heat exchanger uses F1 heat exchanger technology. This makes our heat exchanger dramatically more efficient than the lower cost heat exchangers on the market. The race car heat exchanger is also very light. Combined with CarBahn ST2 software provides large increase in power safely. Please watch the video in this link for more information.  CarBahn’s EVO intelligent software possesses remarkable adaptability to a large range of fuel octanes. Through our software, we employ retuning techniques while ensuring that all critical safety features, which are often neglected, remain intact and add additional safety features where necessary. To gain a deeper understanding of these safety limits, we invite you to watch the informative video available at this link. By recalibrating the safety limits, our software seamlessly adapts from 93 to 100 octane, eliminating the necessity for a customized tune when employing race gas. This unique functionality enables the software to deliver maximum power with each octane variant without compromise. Consequently, there is no need to purchase a custom tune exclusively for race gas usage. Our software is meticulously designed to provide the highest achievable performance output while upholding safety as a paramount concern. Here, the term “intelligent software” denotes the accurate and optimized tuning of the software, avoiding excessive tuning. Our objective is to craft a torque curve that maintains a natural and harmonious delivery, as showcased in this link. We avoid generating excessive torque at low RPMs, which could result in tire slippage, engine stress, and drivetrain failures. By managing torque with a smooth delivery, our software enhances drivability, thereby fostering increased speed and reliability. In contrast to our competitors, who often attempt to maximize performance by pushing boost levels beyond safe limits, our approach prioritizes reliability. We refrain from compromising knock sensitivity and thermal protections, which are vital for safeguarding the engine from potential damage caused by extreme power extraction.

Durability:

Unlike most tunes available in the market, CarBahn’s software maintains the integrity of safety parameters, preserving them to prevent any compromise in engine performance and longevity. Parameters such as knock control sensitivity, super knocking control sensitivity, and catalyst thermal protection are carefully tuned within your OEM software to mitigate the risk of engine and catalyst failure. In our pursuit of optimizing power delivery, we have minimized power losses to a mere 12 HP when reducing these supposed power-reducing software protections. On the contrary, we have witnessed numerous instances of damaged engines resulting from the reduction of these safety parameters. Thus, it becomes apparent that gaining a marginal 12 HP advantage hardly justifies the potential risk of significant engine damage.

Do-it-yourself Approach:

It is essential to acknowledge the emergence of self-tuning tools in the automotive market. While these tools offer the convenience of tuning your vehicle independently, it is crucial to exercise caution. Many of these tools come equipped with pre-set programs that conveniently bypass safety limits, thus posing a substantial risk of engine damage. The art of tuning a high-output engine requires profound knowledge and experience to extract maximum power without compromising the engine’s structural integrity.

Design, Development, and Testing

While the OEM Transmission Cooler is adequate for the G8X in stock form, it starts to come up a bit short on modified/tuned vehicles. Specifically ones that see heavy track/competition use. Transmission oil temperatures have a major impact on the shifting performance of your automatic transmission. If the fluid passes optimal temperatures you will start to see some delays in shifting. Sluggish shifting can be quite frustrating, but the real concern is the damage that can be done to the transmission when temperatures get too high. There are often cases where drivers don’t notice the change in shifting performance due to the gradual onset, but the damage is still being done slowly on a very expensive and important component.

By changing from the OEM single core design to a dual core, CSF was able to increase the overall volume by 194%. This design offers a drastic improvement in heat dissipation and increases the fluid capacity of the coolers by ~94%. Utilizing CSF’s AC Condenser Technology, a 1-Row Super-High Pressure 16mm 9-Channel Microtube design optimizes oil flow and offers maximum surface area contact. These features combine to offer the best possible heat dissipation from the system.

Rock Guard

CSF knows the kind of punishment the front of a car can take on or off the track. The wrong bit of debris flying through the front grille can quickly punch a hole in a cooler. Because the Transmission cooler sits at the very front of the center cooling stack, it is quite vulnerable to damage. In addition, “open face” race style grilles have become quite popular on the G8X. These grilles can add to the risk of debris passing through.

CarBahn has produced the largest and most thermally efficient heat exchanger on the market. Increasing cooling capacity by 40%. This heat exchanger utilizes F1 heat exchanger technology. This heat exchanger technology is dramatically more efficient than the lower cost heat exchangers on the market. The race car heat exchanger is significantly lighter weight.

Increasing boost generates more heat. The addition of the heat exchanger allows you to run more boost safely by reducing charge air temperature. This reduction in charge air temperature also makes more power.  This is particularly noticeable in summer months when ambient temperatures are higher.

When used in conjunction with CarBahn software the addition of this heat exchanger provides enough safety that we can offer a factory matching warranty on your engine and drivetrain.

CarBahn has developed a Toe Link Kit for the F8x M2, M3 & M4 and the G8X M3 & M4 designed to add precision and predictability at the limit.

The Stock Rear Toe Link and Stock Rear Lower Trailing Arm are built with rubber bushings causing excessive deflection. During hard acceleration, these arms flex and allow the rear wheels to have excessive geometry changes. All this flex in the stock suspension links cause the car to be unstable when cornering and pushing on the limits of acceleration. CarBahn eliminates this flex by replacing the rubber bushings with Teflon coated machined steel rod ends.

Most, if not all, of our competitors’ products wrap the rod end in a loose rubber boot, which not only allows to enter but also retain the water and debris which results in excessive noise and a short service life until the rod ends have to be replaced. The CarBahn rod ends are sealed perfectly against water and environmental contamination, thus providing a long, quiet, maintenance-free service life.
