I'm sorry. I'm certain you're making some kind of joke, but it went right over my head. At my age, that happens a lot. For the spectator, expecting a good show, a wheelstand adds to the excitement. For the dragracer, it's an embarassment comparable to missing a shift or running out of fuel halfway d...

Wheelstands=Loss of Motion forward. You don't want to go up, you want to go forward. Watch a Pro Stock Car.
Absolutely! Any force on the wheelie bars means that much less force where it's needed. The fans might like to see both fronts in the air, but that doesn't win dragraces.

Weight transfer is a function of car weight, CG height, wheelbase, and acceleration. The only way a suspension adjustment can affect weight transfer is to change the acceleration. Naturally, you're more inclined to wheelstand with an increase in acceleration. To "fix" this with a suspensio...

Best location for ballast

In another forum, a poster wanted to know whether some ballast weight would do more good (dragracing application) in the rear bumper or above the axle. I thought this was a good question and worked out a graphical solution for him. I figure this question either has been...or will be...brought up in ...

The answer to your question is: Zero seconds. The "still" position of the piston is no different from its position at any other rotation angle. The connecting rod is merely an extension of the crankshaft throw.

I can appreciate and understand your concern over your son's safety. The low torsional rigidity is necessary to promote equal rear tire loading. The front end is, in effect, decoupled from the rest of the car, allowing a large part of the reaction torque from the engine/trans mounts to feed back to ...

So long as your CG height hasn't changed, the no squat/no rise (100% anti-squat) line is still in the same place. So, link settings aren't so much a concern as excessive wheelstands might be.

You might want to take a look at the page in my blog on weight transfer:
