In the world of classic cars, there are several major genres of builds. Some people choose to build hot rods or rat rods. Some build pro street cars with huge drag slicks. Others are into classic nut and bolt restorations. I started out liking the restomod type of builds but then I fell in love with pro touring.

Pro touring is all about improving a classic car in a way that feels and performs like or better than a modern car. In the car enthusiast universe, this is where tuner cars intersect muscle cars. I can show you better than I can tell you.

Exhibit A. This Pontiac Firebird has been modified with performance and handling in mind. Substantial changes have been made to the engine, suspension, and brake systems to the point that it will outperform most stock cars on the road today.

One of the attractions at the Good Guys events is the autocross. Builders showcase their vehicles on a closed course against their competition through timed trials. There is nothing like seeing 30 plus year old cars and trucks being driven hard.

One of the stars of the show this year is this third generation Chevrolet Camaro IROC-Z built by Detroit Speed. It features all of their performance goodies along with plenty of power and braking.

I couldn’t resist this Pro Touring 1969 Chevrolet Chevelle. Really nice performance modifications and engine swap details.

Here are some of the other cars of the autocross pit lanes.
