The S55 Crank Hub: What Tuned BMW M3 and M4 Owners Should Know Before Adding Power
The S55 in the F80 M3 and F82 M4 holds its crank hub in place with clamping force, not a key. Stock, that's fine. Add a tune, bigger turbos or an E85 map, though, and the S55 crank hub becomes the part that decides whether the engine keeps its valve timing. Atlanta's cool fall air is a popular...

Between them, Volkswagen's 2020 coolant bulletin and Audi's 2022 update name six factory coolants: G11, G12, G12+, G12++, G13 and G12evo. That's why VW coolant trips up so many owners.

Blue Smoke Behind Your Porsche at a Norcross Stoplight? The AOS Is the Usual Suspect
You idle at a light on Jimmy Carter Boulevard, pull away, and the guy behind you disappears into a cloud. By the time you find somewhere to look, it has cleared. Then it happens again a week later, and the dipstick is a quarter low even though you topped it up last month. On a flat-six Porsche...
Your Audi Feels Flat Merging Onto GA-400 — Start With a Boost Leak
The car still drives. That is what makes this one easy to live with for months. You put your foot down at the on-ramp, wait for the shove that used to arrive at 2,200 rpm, and get a soft, breathy pull instead — maybe with a faint hiss you can only hear with the window down. Nine times out of ten...

Performance Suspension & Handling Upgrades for European Cars (Johns Creek, Norcross & Atlanta, GA)

Prepping Your BMW for a Summer Track Day at Road Atlanta

Your Mercedes Is Dropping Coolant in the Atlanta Heat — Start With the Radiator
