What happens here

To convert an oval-track chassis for road racing, specific geometry adjustments are crucial. Traditional oval cars often have a raised right-side rail (staggered setup), unlike road race chassis which are symmetrical. This process involves adjusting the lower control arm lengths to achieve equal length on both sides and using wheel spacers to balance the track width. Additionally, the upper and lower control arm slugs can be changed to fine-tune camber gains and other symmetrical aspects of the suspension geometry. The goal is to make these adjustments within the existing chassis structure without requiring extensive cutting and re-welding, which was feasible with the featured 2006 Dodge Charger chassis.

Goal: Modify chassis geometry for symmetrical handling on road courses.

Tools and materials

  • Lower Control Arms — Suspension components requiring length adjustment for symmetry
  • Race Car Chassis Hendrick — The structural frame of the car requiring geometry modification
  • Upper Control Arm Slugs — Fine-tuning camber and suspension geometry
  • Wheel Spacers — Adjusting track width for balanced handling

Charger so does this chassis have asymmetrical frame rail Heights uh no it's actually got a uh raised right side rail um or it it's a little bit staggered it was a leftand turn car but that's what I that's what I was wondering if it's got the you know if it if it's not Square I guess yeah it's Square we moved the rails around left and right up and down you know just from some weight distribution uh you know from Heights but um but other than that the pickup points you can make the geometry work however you want it how how exactly do you do that well really it's basically your you're lower control arm links so you change your lower control arm links so that they're equal length and and the wheel and the tread widths and all that so it's wheel spacer control arm links you can change the upper control arm slugs and the lowers and get your camber gains and all that symmetrical you know both sides and a lot of times you'll see depending on what a car was built for this plate might be over here it might be over here so really it's just a function of the where the arms mounted or how sh you got to run in it or not you know so it's not a problem that way so so you can make it work for these
