Real-world performance is what matters when tuning a vehicle, but let’s not pretend the numbers on a dyno sheet mean nothing. The thing is… How can we trust one result from another? How are different dynos arriving at their calculated power and torque figures? And what’s the deal with drivetrain losses?

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 bearings, ACL Race Series bearings, and coated bearings like those treated by Calico.

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 steering wheel PCB solution (CAN hub) that simplifies installation, reduces wir...

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.
