Weight transfer and reality Think 4D ! Here is where everyone gets wrapped around the axel. In a turn you have weight transfer to the right side. In drag racing when you accelerate your transfer weight to the rear. Absolutely NOT! The only way you can transfer weight is to unbolt it from one...- Ranger Mike

More panhard bar angle down hill will mean more right rear tire load. The intent is to gain maximum tire traction on all 4 tires. Not the SAME load but best attainable load. The left rear will be the least loaded and rt ft max loaded.- Ranger Mike

Read Post 562 on page 19 first – Polar Moment explained. In Physics Moment is the turning effect or rotational tendency produced by a force acting on an object around a pivot point or axis. Pitch Roll and Yaw Every race car driver knows about Roll. It is the left to right turning motion the...- Ranger Mike

Panhard bar mounting location A quick review about the panhard bar. It locates and limits the rear end of the race car form moving sideways in a turn. On paved tracks the panhard bar is anchored to the axel on left side and mounted to the body on the right side. Dirt track cars are the opposite...- Ranger Mike

you said - The sway we did unhook one weekend so it was just along for the ride, that's when we realized we needed lighter springs in it as we were still pushing on exit without the bar. When your race car spins the tires power-on out of a turn but pushes (understeers) when the sway bar is...- Ranger Mike

The 3rd link should be mounted at percent weight position on rea rend and chassis so the bar is not canted or angled so you have most direct action. You loose force when applied at an angle. Panhard bar angle if level does nothing for rear traction. When you angle the bar down hill toward rt...- Ranger Mike

Change panhard bar angle today! If you must run #500 sway abr soften it or disconnect it! See photo below. You are running hollow sway bar I assume. A 1.125" OD 0.125 thick wall tubular bar with 13" long arms( A on pic) = 187 lbs. rating. Same tube arm with 8.75" arm is 415" rating. Maybe...- Ranger Mike

It is always good to check for impact damage. But until you get rid of that massive front sway bar , you will not change the fact that tire spin is due to lack of down force to add traction.- Ranger Mike

With that 500 #arb you turned the race car into a 3000 lbs. go kart very little body roll, very low suspension travel. The ARB or sway bar is way too big at 500# Roll center location has to be changed so you get down force on right front tire. AND Too stiff ARB (sway bar) is holding body roll...- Ranger Mike

Welcome and thank you for the kind words. From what little info you provided, I say you are close to ideal from the book learning point of view. Book says springs are lf 350, rt ft 400, lft rear 225, rt rear 250 to 300 ideal weight is 58% left side. 51% rear, 57% cross weight toe out on 1/4...- Ranger Mike
