It would drive OK at lower speeds, but when driven fast, all four tires would break away & drift. When he explained this, Ron told him the suspension is bound up. No way. They were a Professional Shop and other reasons were suggested. When he inspected it himself, all the suspension was bolted (impacted) into WAY too tight & bound up.When he removed the coil-overs, the front control arm assemblies and the rear suspension would not move freely. This KILLS grip. Before your car leaves the shop, remove the wheels, coil-overs & one link on each sway bar. Each control arm assembly needs to freely move up & down throughout the useful travel range. The rear axle needs to go up & down, plus articulate freely. Then, with a helper, check it all with the sway bars attached.Sway bars binding up is super common. We had a Racer run zero gap on each side of his splined sway bars front & rear. The car handled OK at lower speeds. But, at higher speeds & roll angle, the car lost total grip. News Flash:Sway bars (and torsion bars) get shorter as they twist. His sway bars were binding & shooting the rates to infinity. He added gap on each side & the car handled great.Another client built his tube chassis car from scratch, but didnt check for suspension bind. He had sway bar linkage binding against the lower control arms. With a Monster 1-3/4 GT/NASCAR sway barit literally broke the lower control armsunder hard braking. 530'
