Nerd Rods frame are ONLY sold with the double adjustable coil over shocks and this is why.
Without proper control over both of these factors the car WILL NOT drive, ride or handle like you want making the entire chassis swap ultimately pointless
The coil over shocks allow us to select the proper spring for your car. Then the double adjustable shock allows us to control the precise compression and rebound resistance that your specific spring will need to operate on your car the way you want. By simply adjusting the springs and shocks we can take your car from super cornering G machine to a superior comfort touring car to a cloud. You won’t know exactly what your car will weight when it’s finished and you can’t make the proper adjustments to the stock corvette springs and so we force everyone to purchase these coil overs.
This is the TriFive QA1 Double Adjustable Coil over shock kit. This kit if for a Stage 1 or 2 frames. Stage 3 and 4 frame come with these included.
