SERVING

THE GRAND

STRAND

Coastline Performance LLC is a performance automotive shop based in Conway, South Carolina, serving drivers throughout Horry County and the greater Myrtle Beach area. From supercharger and turbocharger installations to custom suspension, exhaust, and drivetrain work, the shop focuses exclusively on performance builds — work that general repair shops aren't set up to handle.

As the Mainline ProHub dyno and Hunter alignment and tire equipment come online, Coastline is positioning to become the Grand Strand's go-to shop for dyno-verified tuning and precision performance work, on all makes and models.

Forced-induction systems installed and tuned to deliver real, reliable power — not just bigger numbers on paper.

From a single bolt-on to a full ground-up build, every modification is mapped out before a wrench gets picked up.

Coilovers, sway bars, and chassis components dialed in for the way you drive — street, strip, or weekend cruise.

Custom and cat-back exhaust work built for the sound and flow you're after, without sacrificing drivability.

Clutches, driveshafts, and differentials upgraded to handle the power you're adding — built to keep up, not give out.

Thorough diagnostics that find the real issue the first time, using equipment built specifically for performance vehicles.
