OVERVIEW

Custom Modifications. Body kit installation, one-off carbon fabrication.

A bolt-on kit is only as good as the bay it lands in. PACMods has installed and fabricated body work across Porsche, BMW M, Mazda, Aston Martin, McLaren, and the Honda chassis Dusty has been turning into Porsche engine bays on @dusty.build. We dry-fit every panel against factory tolerance before paint, and we say no to kits that can’t be made to clear concours scrutiny.

StartingQuoted per vehicle
THE PROGRAM
01

Body kit installation — fitment is the work.

A Rocket Bunny over-fender or a Garage Vary front lip will only set as well as the installer is willing to dry-fit, modify, and reset. We check every panel against the factory body line before a drop of primer goes on, modify mounting points where the kit and the chassis disagree, and only paint after the fit is signed off. The result is a kit that reads OEM+, not aftermarket.

02

One-off carbon fabrication — when the catalog runs out.

BMW M4 Adro front lip extension, Lotus Evora prototype bumper, Porsche 911 GT3-spec splitter — we cut, lay, and bake carbon in-house for the cars whose catalog parts don’t exist or don’t fit. Patterning is done in CAD against a factory scan or hand-laid molds, with weave orientation matched to the surrounding factory carbon where the panel meets visible structure.

03

BMW, Porsche, Miata, M4 — the platforms we build on.

Most of the kit work landing at PACMods today is on Porsche 911 chassis (991 / 992), Mazda Miata ND, BMW M3/M4, and the occasional G-Wagon W463A. Dusty’s @dusty.build feed documents the build process publicly — what hits Instagram is what comes out of the bay.

04

Lead time — what 6–14 weeks actually means.

Standard body-kit installation runs 6–8 weeks from car-in to delivery. Custom carbon fabrication runs 10–14 weeks because pattern, layup, and cure cycles can’t be compressed without compromising the panel. We give a written timeline at quote and update weekly.

FAQ

Common questions. Custom Modifications.

Q/01How much does a custom body kit installation cost?
A full Garage Vary or Rocket Bunny installation typically runs in the high four to low five figures depending on paint scope, fender modification, and whether one-off carbon panels are included. Quoted per car after a scoping consult — we never give a number sight-unseen.
Q/02Can you do one-off carbon work that isn’t in any catalog?
Yes. We pattern, lay, and bake carbon panels in-house for cars where the off-the-shelf option doesn’t exist. Recent work includes the BMW M4 Adro front lip extension and the Lotus Evora prototype bumper. Lead time runs 10–14 weeks.
Q/03Do you paint and refinish the kit, or just install it?
We do both. Body kit installation at PACMods includes prep, modification where the kit and chassis disagree, paint match via spectrophotometer, spray-and-bake in our booth, and final integration. The kit leaves looking like it left the factory.
Q/04How long does paint protection film last?
Professionally installed Ultrafit paint protection film carries a 10-year manufacturer warranty against yellowing, cracking, and delamination. In Pacific Northwest conditions, the film typically performs well past the warranty window if washed correctly and not exposed to chemical contamination.
Q/05How much does PPF cost in Seattle?
Full-body PPF on a luxury or exotic vehicle at PACMods starts at the upper end of the Seattle market because we work exclusively with concours-grade Ultrafit film and back every install with a 10-year warranty. Partial coverage (front-end, track package, or high-impact areas) starts lower. Request a private estimate for a vehicle-specific quote.
Q/06What paint protection film do you install?
PACMods installs Ultrafit — a top-tier self-healing paint protection film with a 10-year warranty. It is optically clear, hydrophobic, and swirl-resistant; we select the coverage tier and finish (gloss or matte) per vehicle and intended use, from daily-driven streets to dedicated track time.
Q/07How do I pay, and do you take a deposit?
We accept credit cards, debit cards, and NFC mobile payments. Payment is due on completion, before the vehicle leaves, unless the written quote says otherwise. A deposit may be required where the build needs parts we order in and those parts come to more than $500 — it covers the order, and it is set out on the written quote before any work starts. We do not bill insurance carriers, so the number on your written quote is the number you pay.
Q/08Do you work with insurance companies?
PACMods is an independent shop by intention and does not work with insurance carriers. We perform cosmetic and collision repair on a direct-pay basis for owners who want concours-quality work without the carrier-driven shortcuts that compromise luxury vehicles. We can help you understand what an insurance reimbursement might cover, but the work itself is between you and us.

Team is very professional, friendly, and most importantly fast. Before work they made sure to confirm every miniscule detail of the project with me, and after I had left my car at the shop the team made sure that they return the car as soon as they can. After I have collected the car the team made sure that everything was up to my liking, and even checked in with me a couple months after.

Prestige Automotive Customs lives by the principle, “Do it once, do it right.” They have the skills and attention to detail needed for custom automotive work. I needed a dash-cam/rearview mirror installed, something beyond a typical maintenance repair. Prestige had the knowledge and expertise to do it properly. As a family-owned business, Prestige Automotive Customs takes great pride in their work, and their exceptional workmanship shows. I highly recommend Prestige Automotive Customs for your custom automotive projects.
