BMW M4 Build Part 1

October 31st, 2026

So having a plan of doing as many road trips as possible lead to the decision of choosing a car that can do it all without being too expensive to throw on a track. We have a 2024 Defender 90 that does the winter adventures and sticking a roof tent on, so what do we use for summer and track work?

After viewing and driving various cars ranging from a Porsche 911 to Nissan GTR, we settled on an F82 BMW M4. Everything else was too focused and good in their respective category whereas the M4 seemed like a good platform to build on.

We were able to find a completely stock Ultimate Package M4 Competition in, what we think is the best colour, San Mario Blue. The ultimate package basically came with all of the best options minus the carbon ceramic brakes.

The plan with the car is to make it the best hybrid between a fast road car and a capable track car. If you know anything about cars, you know that BMW have one of the best names on the road and track!

Although most of the work will be under the skin, on day one, we ended up putting a Carbon CS styling kit on it to give it a little more road presence and aggression courtesy of out friends at Carbon Factory. We also fitted it with a CS Style bonnet from Audi ID!

BMW M4 Build Part 2

February 7th, 2026

After the initial styling enhancements, we needed to address the handling, braking and grip. Unfortunately our bank accounts are not bottomless meaning that we resorted to forums and Facebook groups to find out which parts are crucial and most effective for a fast road/track capable set up.

For handling, we went for a lovely set of adjustable MMX springs to get the perfect ride hight, a little more cornering support and adjustability. We also added Millway Street Adjustable camber top mounts to allow a much more aggressive camber angle at the front. Both of these upgrades along with a full geometry set up from The MotorWorks has given us a very well balanced but aggressive road car which is more than capable to be thrown around the Nurburgring!

Further to the handling, we addressed the braking performance but upgrading to some HEL braided brake lines and some Ferodo pads. While these parts were being fitted, our friends over at RD Motorworks flushed the brakes through with some Motul RBF660 brake fluid. After a few long days or road and track, we can confirm that these small upgrades have transformed the brakes. The next hurdle to over come will be brake cooling.

Saving the best for last! To make sure that all of out handling and brake upgrades are effective, we decided to go a little bit crazy with the whees and tyres. 19 inch Apex VS5RS wheels in Motorsport Gold, shod in either Michelin pilot sport cup 2 tyres (dry weather) or Continental Sport Contact 7 tyres (wet weather) was the choice!! No only do they look amazing, they have transformed the car. Both front and rear wheels are winder giving us a massive amount of mechanical grip and also keeping the weight similar to what the stock wheels are tyres were. The apex wheels are fully forged and SO MUCH stronger than the stock option.

BMW M4 Build Part 3

February 12th, 2026

Having now been able to experience the car on both some amazing driving roads, British tracks and the Nurburgring, the general consensus is that the car is EPIC! However, there are few gremlins that we identified in different scenarios.

The first gremlin was the gearbox. In stock form it seemed fairly unsure, clunky and made the throttle response really sensitive. After some quick googling and some input from the Facebook M4 Owner group, we were told about the GTS Gear Box, Traction control and ABS tune. The M4 went back to RD Motorworks to be tuned and what a difference it makes!!! Its feels like a new bloody car. So much more responsive in gear changes but so much smoother around town!

Next was a little bit of aerodynamic help. We noticed that we were fairly unstable into fast speed braking zones (mainly on track). Also, everyone at the Nurburgring seems to have very fun rear spoilers.

At the back of the car we opted for the Ridgeline Ring Spec wing with the GT4 Risers courtesy of our prints over at Clubsport Garage. Not only does it look cool but we have noticed a huge difference in high speed stability. We’ve paired the spoiler up with a custom built chassis mount two piece front splitter. The top part if the splitter consists of a cut in half carbon air dam with the lower chassis mount element sandwiching it all together. We did this for performance but also for the cost effectiveness.
