Pfadt Race Engineering continues developing heavy-duty suspension components for the hardcore racing enthusiasts. Their target demographic is the LS crowd, with a particular focus on the C5/C6 and 5th-Gen Camaro owners. They’ve just launched a new Johnny O’Connell Stage 2 Black Edition coil-over system just for C5 and C6 Corvettes. Read all about it below!

Official Release:

Pfadt Johnny O’Connell Stage 2 “Black Edition” Signature Suspension

Following up on the wildly successful Stage 1 package, Johnny is back and this time he has developed a specific package for Corvette owners who hit the track often!  Johnny tailored this package with unique track-based coilover valving coupled with spring rates and sway bars that you can easily drive on the street.  The Stage 2 “Johnny Black” package picks up right where the Stage 1 left off and moves to a fully adjustable coilover system and fully adjustable front and rear Light Rate race sway bar set.

This package was engineered to the specifications you have come to expect from a Johnny O’Connell Signature Suspension: reliable hi-performance operation day-in and day-out with no additional parts necessary to meet your goals.  Open the box, install the parts, get an alignment and then see the seconds come off of your laptimes!  No need to mix and match parts, this package is designed to work together so you don’t have to be a race engineer to get the car set up correctly.  

Instead, you can feel confident in knowing that your car’s suspension was tuned by legendary Corvette Racing driver Johnny O’Connell right out of the box, and no further parts are needed for the proper track set-up.  You only need to follow Johnny’s recommended starting points or adjust for your desired outcome as needed!
