Chassis & brakes · Film & wrap

School run on Monday, track day on Saturday. Sharper turn-in without wrecking the ride on Michigan concrete.

Chassis

  • Two-way adjustable coilovers, set street-firm
  • Front camber plates
  • Four-wheel alignment to a track-day sheet
  • Corner-weighted with driver ballast in the seat

Brakes

  • Street-track pad compound, front and rear
  • High-boiling-point fluid, full flush
  • Pads bedded on a closed road

Film

  • Full-front PPF, gloss, edges wrapped
  • Ceramic tint on the rear doors and tailgate

Sign-off

  • Every suspension fastener torqued and marked
  • Road test, then alignment re-checked

Starlight headliners

Lights out.
Stars on.

Fiber-optic stars pulled through the headliner one at a time. You pick the density, the pattern and the color; the headliner goes back in on its own clips.

  • Your density and pattern
  • Single color or RGB
  • Twinkle or static
  • Dimmable, with a clean off

Services

One car, every finish

Cast vinyl, laid indoors at panel temperature. Trim and handles come off where they need to, so edges tuck behind seals instead of stopping at a gap.

Full color change · Satin, gloss or matte · Chrome delete · Door jambs on request

Also in the workshop: tuning, exhaust, mechanical, tires & wheels.

Q.01Tuning

Will a flash void my warranty?

Not the whole warranty. It can cost you a claim.A tune doesn't cancel the warranty outright, but a dealer can refuse a claim on anything the tune could have affected: engine, turbos, gearbox. Most ECUs record that they were flashed, even after a return to stock. We go through what's at stake on your car before we touch it.

Question 1 of 8: Will a flash void my warranty?

General answers. Your car, your warranty and your state's rules decide the specifics.

  • Photographed as it came in
  • Leaks, bushings and fluids checked first
  • Findings go on the ticket before any work

The hours nobody posts: metal cut back, wheels off, fluids in. Every car gets them before it gets a road test, and the road test comes before the keys go back.
