Lake Speed's 90's NASCAR Thunderbird Resurrection: Running 780hp Wide Open at 75 Years Old!

What happens here

The car's ride height is measured at multiple points (front, rear, left, right) using a specialized measuring tool. This process, often referred to as 'scaling' or 'setting frame heights,' is crucial for establishing the car's ground clearance and initial suspension geometry. The goal is to achieve a neutral setup, meaning the car will handle similarly when turning left or right. Adjustments are made to the suspension to fine-tune the balance, ensuring the car doesn't drag on the ground while maintaining optimal handling characteristics. This baseline setup is vital before any track testing.

Goal: Achieve a neutral chassis setup by adjusting ride height and weight distribution.

Tools and materials

  • Ride Height Measuring Tool — To precisely measure the distance from the frame to the ground
  • Wrenches/Sockets Mac Tools — To adjust suspension components (e.g., spring perches, control arms)

in and just go run it what are you trying to figure out right now you calling me fat on 1 8 over [Music] time can you explain what you were doing for somebody who doesn't know what that is for which thing the frame Heights and all that the frame Heights and everything is your ground clearance is the biggest thing you're closer to the ground you're all the better the car is going to be but you can't be dragging the ground obviously either but uh getting the getting frame Heights so that you don't drag but you're closed and then getting the uh the wedge in the car is just for balance and turn so you're just as tight turning right as you roll then you get the racetrack and you start running on the track then if there's a place that you're too loose or too tight then you adjust from there but this is just to get you a baseline And basically what we're trying to do is have the car neutral same way you know turn this have the same grip both directions when you go start out and you wanted to find the belt Heights of the chassis so you knew what Center what we were doing before but in mind I'm pretty sure you want to set it to where the car is built to run and if these frame rans are five in the front five in the back then the suspension points and everything are meant to run with that frame at that height then that's our starting point basically then all the other measurements can be done you can't just drop it as low as you want because then your camber curve and all that's going to be everything wrong is affected camber faster toe everything's affected by that it drove really good last time it was out so we want to put it back where it wants a little bit one thing you got to remember though good every time it's going to be quite a bit more throaty
