Inside the Hottest Booths at SEMA 2025
The SEMA Show stands alone as the ultimate proving ground for the automotive aftermarket world. No other event brings this level of innovation, craftsmanship, and straight-up creativity together in one place. Everywhere you turn, there’s something new—fresh tech, wild ideas, and custom builds that push boundaries in ways only SEMA can inspire.
GOLDEN ARCHES
As enthusiasts, when we build our cars, we tend to stuff as much tire under those cars as possible. This is especially important for rear tires that hook the car to the ground while improving its stance. For those interested in drag-racing their cars, you will need to accommodate larger rear tires or slicks. The current hot trend is the 10.5-inch slick, which seems to work well on many applications, but depending on the make and model of your car, it may require modifications to enlarge the rear wheel openings to accommodate the larger rubber.
GETTING THE SPINS
While it is true that a turbo system does not have the instant response of a supercharger, the new Turbonetics T3/T4 Hybrid turbochargers are closing that time gap. Turbonetics has formed a complete lineup of products that take a T3 turbine section (in standard, Stage 2 or Stage 3 trim), that is then coupled with a T4 compressor section (T04B trim or T04E trim). The result is the T3/T4 Hybrid, which combines the low inertia and fast boost response of the lightweight T3 turbine wheel with the high airflow characteristics of the T4 compressor. These characteristics combine to make the T3/T4 Hybrid the turbo of choice for high-performance import applications.
