A Real Home on the Internet

It's official — Wisco Speed & Performance finally has a real home on the internet, and you're standing in it. For years, the best way to see what we were up to was to swing by the shop in Rosendale or scroll our Facebook and Instagram feeds. Those aren't going anywhere. But now there's one place where everything we do lives together, and we couldn't be more fired up to show it to you.

Everything We Do, In One Place

If you know us, you know GM performance is our bread and butter — but the new site lays out the whole picture, from the daily-driver work that keeps you on the road to the builds that keep us up at night:

  • Engine builds — from healthy refreshes to full custom builds, assembled here and proven here.
  • Dyno tuning — real numbers on our dyno, not guesses.
  • EFI conversions — bringing carbureted classics into the modern era with drivability to match.
  • Wheel, tire, brake & suspension packages — the right setup for how you actually drive.
  • And the honest maintenance and repair work — tires, alignments, brakes, fluids and more — for the vehicles that get you to work on Monday.

Our favorite part of the new site is the Builds & Projects gallery. It's a running record of the cars and trucks that have rolled through our doors — the customer builds, the project vehicles, the before-and-afters. If you've ever wondered whether we'd respect your car, this is where you find out how we treat everyone's. Take a look, and if you spot your own ride in there, you already know.

Getting Ahold of Us Just Got Easier

The whole point of the site is simple: when you're ready to talk about your car, we want that conversation to be one tap away. Call us directly at (920) 579-0605, or fill out the quote request form — tell us what you're driving and what you're after, and we'll get back to you with a straight answer and a real quote. No runaround.

Thanks for Riding With Us

This shop runs on the people who trust us with their vehicles — the neighbors who bring in the family hauler, and the gearheads who trailer in their pride and joy. This site is for all of you. Poke around, check out the gallery, and keep following the daily builds on Facebook and Instagram. More posts are coming right here on the blog — build features, shop news, and the occasional dyno-day story worth telling.

See you at the shop.
