Is the BMW M2 the most important M car of the modern era?

Not because it’s the fastest. Not because it’s the most powerful. But because it might be the purest.

The G87 M2 is the right size. 4,580mm long. Compact by modern standards. It doesn’t feel bloated like the M3 or M4. It’s a proper driver’s coupe with pumped arches, muscular proportions, and a front end that’s aggressive without being a caricature.

It’s rear-wheel drive. No xDrive from the factory. That’s becoming a rarity in the M lineup.

And the tuning potential? It’s absurd. The S58 engine responds to tuning like few others, and the tuning scene has taken full advantage. Tom Wrigley Performance has even built a 1,500hp, xDrive-converted M2 using OEM M3 and M4 parts. The fact that this car can be transformed into a four-wheel-drive monster is a testament to its engineering.

BMW M is going electric from 2027. The M2 will remain in production until 2029. It’s not the last petrol M car, but it might be the most authentic one left.

This particular example, spotted at a recent MSV track day, wears Tornado Red paint over silver and polished BBS E88 splits wrapped in Nankang CR-S tyres. Subtle at first glance. Then the stance hits you. Properly sorted.

If you’re preparing your own M2 for track work, we’ve got you covered. From tyres and suspension to brake upgrades and alignment, we know these cars inside out.

Is this the M car that defines the era? We’d argue yes.

Helix have been making clutches for cars going right back to the 1970s. And if they don't have it, they'll make it.

That's the thing about Helix. They're not just a catalogue. They're a solution. Whether you're refreshing a classic or building something that shouldn't exist, they have the knowledge and the manufacturing capability to sort it.

Everything is made in-house, in the UK. The quality is second to none, the service is personal, and the answer to "can you make this work?" is usually yes.

So if you're working on a retro build with an engine and gearbox that were never supposed to meet, or you just need a clutch that actually fits your vision, get in touch. We can help you achieve the solution you need.

Your brake lines are old. Probably rubber. And probably expanding when you need them most.

OEM brake lines do a job. But they're a wear item, and rubber perishes over time. More importantly, when you're really leaning on the brakes - track day, spirited drive, or an emergency stop - that rubber line expands under pressure. Some of the force you're generating at the pedal is going into ballooning the line instead of stopping the car.

Goodridge braided brake lines solve that. The stainless braid resists expansion, so more of your pedal input reaches the calipers. Sharper pedal. More consistent feel. Better braking control.

It's not about shorter stopping distances on paper. It's about the connection between your foot and the caliper. That's what transforms your confidence in the braking zone.

They're corrosion resistant too, and they come with an outer sleeve in various colours - clear, black, whatever suits your build. So they're a visual upgrade as much as a performance one.

If you're refreshing your braking system or upgrading pads and fluid, do the lines at the same time. It's a small cost for a noticeable difference.

Can you save money on track day kit by using karting racewear instead of motorsport racewear?

Short answer: yes.

Here's how it works. Low-end racewear and high-end kartwear sit at similar price points. The main difference? Fireproofing and homologation. Kart gear doesn't carry the FIA flame-retardant certification because karters don't need it. They need abrasion resistance, grip, and feel.

For a track day, you probably don't need fireproofing either. That means your money goes further. Instead of paying for a certification you won't use, you're getting higher-tech materials, better features, and more comfort for the same spend.

Of course, it's your call. If your car is approaching race car spec, or you're thinking about going racing in the future, homologated racewear makes total sense. It's built for that environment.

But if you're doing track days in a fast road car, kartwear is a smart way to get proper kit without the premium. The choice is yours. We've got both.

The easiest way to give your car more power is to install a drop-in panel filter.

Pop the lid off your airbox, bin the stock paper filter, drop in the Ramair panel. Job done.

You get better airflow, which means more air into the engine, which means more power. And before you ask, no, you're not sacrificing filtration either. Ramair panels feature the same filtration properties as OEM equipment thanks to the proper research and development that goes into every product.

Most drift cars are built to be abused. This one was built to be admired. Then abused anyway.

There's a moment in drift culture where function meets finish. Where a competition missile gets elevated to something you'd put on a show stand. That's this Zenki S14.

The bones are pure race car. Fully multipoint cage tied into the chassis. Lexan windows. Adjustable suspension. A 1JZ under the bonnet that's been detailed like a show piece. R8 coils. V-bands. Tomei clear cam cover. Black and gold lace-painted rocker cover and turbo. Billet inlet and throttle body. The full Chase Bays catalogue, everything colour-coded and immaculate.

Then there's the interior. Option buckets with sprinkle inserts and gold glitter backs. Yellow TRS harnesses. A gold cage that matches the theme. This isn't standard drift spec. This is someone saying "I want to compete, but I want it to look incredible too."

Outside, it's aggressive but restrained. Plain black bodywork tames the kit. Gold-centred BBS with massively deep, stepped polished lips and spiky wheel bolts. Stickers confined to the windows. And then the scars. The front bumper held together with cable ties. The leading edge bearing the marks of a good time.

It's a Zenki, not a Kouki. The original S14 shape, before Nissan sharpened it up. Most people chase the later front end. This one didn't. That's a deliberate choice, and we respect it.

The black and gold JPS-inspired look is classy. But this 200SX is all attitude.

Something to make your first track day a lot easier... a friend.

Someone to share the nerves, the laughs, and the inevitable moment you end up in the gravel. Someone who'll remind you about it forever.

Two heads are better than one, especially when it comes to remembering the essentials. If you need a hand sorting helmets, tyres, or anything else before you go, you know where we are.

Road tyres. Track tyres. And then there's the RainSport 5. The tyre that blurs the line when the weather turns.

We see these on everything from daily drivers to dedicated track cars. The reason is simple. When the heavens open, the RainSport 5 delivers grip that feels almost unreasonable for a road tyre . Shark Skin Technology channels water away with minimal turbulence, and the Aqua-Twist sipes clear the contact patch fast .

For track day drivers, that means confidence in conditions that would normally end the session. For everyone else, it means a tyre that makes British weather feel like less of a gamble.

With autumn setting in, now's the time to think about your wet weather setup.

Up to 50% off Vogtland lowering springs. If you've been thinking about lowering your car but don't want to break the bank, this is your moment.

Vogtland Sport Springs lower your centre of gravity, sharpen up the handling, and give your car that aggressive stance without turning it into a bone-shaker. They drop the ride height while maintaining a surprisingly comfortable ride for daily driving. The compound spring rates keep things civilised on the motorway but firm up when you push it through the bends.

All Vogtland springs are developed, tested, and cold-coiled in Germany from high-tensile chrome-silicon steel. Each set is vehicle-specific, with TÜV certification for road safety. It's the sort of quality you'd expect from a brand that's been making springs since 1908.

A more planted stance, a sportier feel, and up to 50% off. Head to the website to check fitment for your car.

Your brake fluid is the most overlooked component on your car. Until you're halfway through a session and the pedal goes soft.

If you're running a modern performance car on track, you're putting serious heat into your brakes. Standard road fluid doesn't stand a chance. That's where Orthene Halo GT comes in.

It's a DOT 4 racing fluid built for abuse. A 336°C dry boiling point. Methyl borate ester formula for low compressibility and high thermal stability. Ultra-low viscosity for faster piston release and quicker ABS response.

And the bit that matters for modern cars: full Bosch M5 ABS compatibility. If you're running a complex ABS system, you need a fluid that keeps up. The Halo GT does.

Consistent pedal feel from the first braking zone to the last. No long pedal. No fade. Just repeatable performance lap after lap. Even a drift car with its factory ABS intact can benefit from that kind of consistency.

We see a lot of dedicated track and performance builds through our doors. If you're serious about your time on track, your fluid needs to be part of the conversation.
