3) on a big max chassis the upper frame tubes extend further behind the cockpit before bending down to meet the rear torsion tubes.
4) those are chassis measurements, the first number 86,87,88 are wheel base length. The second number is drive line length 39,40,41 the distance from motor plate to rear axle.
5) wing cars generally use a 50" axle, nonwing uses a wider front axle and run the right rear further out to create more offset to the left and create a wider wheelbase.
1d) right rears breaking off is caused by axle/wheel center fatigue from running a light weight axle to many nights or from contact with walls/cars/big gnarly cushion that feel like walls.
2b) cars bicycle because they are setup to tight, catch a rut, driver hits the cushion to hard, it is how things are. Not much weight, wheel base width, or down force to hold them down.
Thank you, Whit11B
That explains a ton. Personally, for me I'd rather give up a little weight and know my RR wasn't leave at a bad time, those wrecks look the worst from what I've seen so far.
Who are the best Non-Wing builders?
Does 5 bar make a difference in stability?
