Most people won't expect this crossover.

Tuning cars is very similar to tuning trail bikes.

Cyclists speak a different language from car enthusiasts, but they're chasing the same passion in a different form. Cars have corner-balanced suspension, mountain bikes have finely tuned shock settings.

Cyclists are shaving grams off their rigs, car enthusiasts are leaving their back seats at home.

Cyclists and car enthusiasts both look for the fastest way around each corner, and personal best times are posted on their IG stories at the end of every weekend.

Just so when you think that trail bikes and modified cars don't have anything alike, just take a moment and look at this photo.

Track Day Essentials: Functional Aero Vents

Car enthusiasts who do track time know that it also takes exterior modifications to prep a car for the racetrack. One of these is adding aerodynamic vents. Real and functional vents.

Adding vents to your car gives you the ability to manage the airflow, reduce lift, and enhance cooling.

R Theory has both Hood (Bonnet) and Fender (Wing) vents. We have aero vents for:
Mazda Miata MX-5 (NA, NB, NC)
Honda S2000 (AP1, AP2)
Toyota GR86, Subaru BRZ, Scion FR-S
Volkswagen Golf MK7 (GTI, R, TSI)

Visit the R Theory Motorsports website to get functional aero vents for your car. If there is a car that isn't listed, you may check out our Universal Hood (Bonnet) vents for wide or long types.

What do you think of a daily looking like a racecar? For us, it's always a sight to see.
