Digi Sports in Grantville has run a combined San Diego automotive-electronics and racquet-sports operation from 5805 Mission Gorge Road since 2004, making the 92120 shop one of the longest-tenured window-tinting and car-audio installers on the Mission Gorge corridor. Window tinting — the primary service line — covers automotive, residential, and commercial glass using Johnson Window Films and Solar Gard product lines, with ceramic and smoked film options that block up to 99 percent of UV radiation while meeting California's 70-percent VLT front-door requirement. The shop uses a ComputerCut® plotter system that pulls vehicle-specific templates from a digital database, pre-cutting film to the exact curvature of each window before the installer applies it — eliminating freehand blade work on the glass surface and reducing the risk of scratches on factory tint and defroster lines. Auto-electronics installation spans alarm and security systems, backup cameras, parking sensors, LED lighting, navigation units, and full audio-video upgrades — a scope that complements the auto-glass and detailing work at AMB Auto Glass and Window Tint a few blocks south on the same Mission Gorge Road corridor. Paint protection film installation covers hood, fender, bumper, headlight, and mirror surfaces, with full-front PPF packages priced as bundled kits that reduce per-panel cost compared to individual-piece orders. The badminton and tennis retail counter is the second half of the business: racquets, shoes, shuttlecocks, grip tape, and on-site stringing at $25 for badminton and $32 for tennis, with one-hour turnaround for walk-in restrings during business hours. Vinyl vehicle wraps and graphic installations round out the automotive side, from full-color commercial fleet branding to matte and satin color-change wraps on personal vehicles. Mission Gorge Road between Friars Road and the Santee border concentrates the highest density of auto-service businesses in the area, and drivers heading to 3B Smog Check Station for biennial emissions testing often combine the trip with a tint appointment at Digi Sports on the same stretch of road. Residential and commercial window tinting extends the company's scope beyond vehicles, with solar-control and privacy films available for office buildings, storefronts, and homes throughout San Diego.
