Wrenchmasters in Santee specializes in classic car and motorcycle restoration from its Argent Street shop, with particular focus on GM Oldsmobile platforms and Ducati motorcycles alongside all domestic and import makes. The shop handles Ducati desmodromic valve adjustments, timing belt replacements, and clutch service — Italian-specific maintenance intervals that overlap with the powersport parts pipeline at Darkside Customs on Prospect Avenue. Classic car services span carburetor rebuilds and synchronization, points-to-electronic ignition conversions, and fuel injection retrofits that modernize driveability without altering period-correct exterior appearance. Post-restoration paint correction and ceramic coating prep coordinates with Dali Detailing on Woodside Avenue for single-stage and two-stage finish polishing before protective sealant application. Engine swap and performance upgrade packages include small-block and LS-series crate motor installations with ECU wiring harness integration, exhaust header fitment, and dynamometer-verified tuning.
