PRO3 Racing: Inside the Northwest’s Premier E30 Spec Series

🏁 What is PRO3 Racing?

PRO3 is the Pacific Northwest’s premier spec racing series for BMW E30s—the beloved 1984–1991 3-Series chassis. Sanctioned by ICSCC (International Conference of Sports Car Clubs) and SCCA, PRO3 offers a level playing field, low operating costs, and incredible door-to-door racing.

Drivers run similar builds with strict spec rules to focus the competition on driver skill, racecraft, and consistency.

🎯 “Momentum racing at its finest”—that’s PRO3 in a nutshell.

Whether you’re a novice stepping up from HPDE or a seasoned driver wanting budget-friendly competition, PRO3 delivers.

🛠️ Key Build Requirements for PRO3

While builds must meet strict guidelines, smart choices in quality parts can still give you an edge in reliability, precision, and drivability.

🔹 Suspension & Handling

Control arms and bushings must meet spec, but quality installs and alignments are critical.
Ride height, camber, and damping adjustments within allowed tolerances can make a huge difference.

🔹 Cooling & Engine Protection

The E30’s M20 motor is bulletproof—but it needs protection under race heat.

🚗 AAF Performance Parts That Shine in PRO3

✅ AAF Oil Pan Baffle for BMW M20 Engines

In PRO3, high-G corners can lead to oil starvation—a death sentence for your motor. The AAF oil pan baffle is race-tested to reduce oil slosh and preserve oil pressure under sustained load.

🧰 “Set it and forget it” insurance for your bottom end.

✅ AAF Adjustable BMW Shifter

Tired of vague shifts or missed 3rd under pressure? The AAF adjustable shifter offers:

Short, tight throws
Fully customizable height and throw ratio
Bolt-in design tailored for E30 race builds

🔄 Shift with confidence every time you dive into the braking zone.

✅ AAF Brake Cooling Kit

PRO3 rules demand stock calipers and rotors—but that doesn’t mean you have to suffer from brake fade.

AAF’s brake ducting solutions funnel air straight to your rotors, helping you:

Reduce fade in long races
Extend pad and rotor life
Stay consistent deep into the session

✅ AAF AiM Solo Mounts for Roll Bars

Data is crucial in any spec series. Use an AiM Solo 2 DL to track lap times, throttle input, and braking zones—mounted securely with AAF’s custom roll bar bracket.
