/// About Corner3
Daily drivers. Track cars. Everything between.
Corner3 is a five-bay independent garage in Laguna Hills. We work on daily drivers, family SUVs, and project cars — and the same hands touch all of them. No service writer between you and the tech who diagnosed your car.
Every job starts with a written estimate. Itemized labor, itemized parts, itemized fluids. You see the breakdown before we touch a bolt — and you get to choose OEM, OE-equivalent, or aftermarket per line item.
If we miss a quoted time, that's on us. If we miss a quoted price, that's on us too. The point of being independent is being accountable.
/// Capabilities · 006 services
What we work on.
001 /
Diagnostics & Tune
Check-engine lights, drivability issues, intermittent faults. We pull live data, scope the signals, and tell you the root cause before any work starts.
002 /
Brake Service
Pads, rotors, calipers, lines, fluid. Spec-matched friction for street, sport, or track. Road-tested before delivery.
003 /
Suspension & Alignment
Struts, shocks, coilovers, control arms, bushings. 4-wheel alignment after every install — we don't hand back a misaligned car.
004 /
Engine & Drivetrain
Timing service, clutches, transmissions, mounts, gaskets. We do the work most independents send out.
005 /
Performance Builds
Intake, exhaust, tuning, coilovers, brakes. Bolt-on packages installed correctly the first time — no rattles, no leaks.
006 /
Pre-Purchase Inspection
Buying used or sourcing a project car? We'll inspect the whole car and send you a written report with photos before you hand over a check.

From the lot.
“Took my M3 here for a full brake refresh after the dealer quoted me almost double. Better parts, faster turnaround, and zero squeak after install. They earned a customer for life.”
“I've been bringing both family cars here for five years. They've never recommended a service I didn't need and they explain everything in plain English.”
“Built my WRX up with them — intake, downpipe, coilovers, full alignment. The work is clean and the tune feels stock-smooth. Best independent in south OC.”
