R&L Performance in Chula Vista delivers general mechanical repair and performance work from 887 Palomar Street, near the Interstate 5 and Palomar Street interchange that anchors the city's southern industrial corridor. The shop handles engine overhauls, transmission service, AC repair, and full brake jobs across Japanese and domestic platforms — a broad import-and-domestic scope that often runs parallel tire-and-alignment jobs through Big Brand Tire & Service when worn suspension components demand fresh rubber. Cooling-system work covers radiator replacement, thermostat swaps, water-pump service, and heater-core flushes on high-mileage Toyota Camry, Honda Civic, and Chevrolet Silverado platforms common in the 91911 commuter fleet. Suspension diagnostics address strut assemblies, control-arm bushings, sway-bar end links, and CV-axle boot tears, with test drives on Palomar Street verifying elimination of clunks and vibrations before release. Post-service exterior reconditioning for vehicles that sat in the shop during multi-day engine or transmission builds can be scheduled through mobile providers such as Magic Mike Mobile Detailing for on-site paint correction and interior cleaning. Technicians perform fuel-injector flow testing at rated pressure using an ultrasonic cleaning bath and graduated cylinders to measure spray-pattern uniformity across four- and six-cylinder banks.
