Tuned In

We often chase engine and tuning upgrades first, but could a front splitter and rear wing be a smarter starting point for our race cars?

We caught up with Kyle Forster from JKF Aero to break down how aerodynamics work in practice and how to make effective improvements at every level of motorsport. From the priorities of downforce vs drag, to choosing the right aero balance for your car's drivetrain layout, this conver...

Some bearings are tough enough to survive 3000 horsepower, but that doesn’t mean you should use them in your street build.

Choosing the right bearing isn’t as simple as just picking the toughest option and sometimes what seems like a part from 'the top shelf' can do more harm than good. In this interview, Christian from Nitto Performance Engineering breaks down some small but key differences between OEM-style bea...

Think getting extra speed out of an aero package is just for the pros with all the money? It’s not... But you DO need to know what you’re doing. 

This week, we’re sitting down with aero specialist Amir Bentatou from RS Future to discuss creating an effective aero package for your vehicle, how to actually test it, and much more.

3D scanners are not always cheap, but here's why they might still be worth your money.

3D scanning is changing the game for motorsport and custom fabrication, and tools like the Peel 3 scanner are bringing that capability to a more affordable level. In this interview from SEMA, we speak with Gabrielle Williams from Peel 3D/Creaform about how this tech works, where it's most useful, and what enthusiasts need to kn...

Anyone who knows modified cars will have heard of the Ring Brothers, builders of some of the greatest custom machines ever conceived. With huge scope and an equally impressive price tag, these incredible vehicles take every single piece of a build to the next level. This week, we’re sitting down with the fabricator responsible for bringing these works of art to life.

Say goodbye to messy curly cords and more potential failure points.

Steering wheel-mounted controls make it easier to adjust key functions on the fly, but getting those signals from the wheel to the car is not as simple as it sounds. Running multiple wires through a rotating steering column is unreliable, time-consuming, and they can be prone to failure due to the nature of their use. Zestek has developed a CAN-based steer...

Car brands are secretly limiting your car’s potential, and it has NOTHING to do with reliability.

Getting more power out of a factory car can be surprisingly straightforward with the right software (and sometimes hardware modifications), but what goes into developing a proper tune that exploits more potential without pushing the OEM compo...

When Joel Vermiglio isn’t working his day job at McLaren Formula 1, he’s in his Garage 68 Motorsport workshop building an old VW Caddy… with a McLaren twin-turbo V8 in the rear tray, a Lamborghini gearbox, and Porsche 911 suspension.

S15 suspension in a 240Z—good idea or nightmare?

Joel Dimmack’s 1971 Datsun 240Z is no ordinary drift car. Running a VR38DETT swap with Garrett GTX3071R mirrored turbos and making 600-700hp, this 1100kg wet monster blends old-school styling with modern competition-ready tech. But is an S15 suspension transplant really the best setup for drifting?

The performance EV landscape is changing rapidly, and public opinion on electric vehicles also seems to be on the move. How much faster can they go? What are their limitations? Are they even still relevant?

A lot has changed since we first had this week’s guest, Sasha Anis of Mountain Pass Performance, on the podcast back in 2022. This conversation gets us right up to date on where the industry sits now and what it’s goin...

When it comes to performance parts and tools we all want to reach 'straight for the top shelf' and get the best we can. While that isn't always possible for some high price components, when choosing between purple, blue or red Loctite at the same price point, many assume that red must be the strongest and therefore 'best' option.

These people are wrong, and they're possibly also applying the c...
