Good find, someone grab this!

 

These are really useless for our cars seeing as we have a beam back there. More an aesthetic mod rather than performance...just saying...

 

Thanks for the heads up. Was about to get this.

 

How does having a beam affect chassis flex?

 

Do you have one?

 

Ive had one but simply as a visual mod. Felt no difference. Got an RSB and noticed the difference right away. Have sold the RSTB to make room for a system.

 

How does this relate to a beam axle?

 

There is definitely a difference made. Not as much as a RSB but enough to justify purchasing one.

 

These are FWD cars.....so a SOLID beam axle would see very minimal chassis flex. Couple halfshafts with most of the vehicle weight VS. a beam with little weight in comparison. Which would flex more?? Think of the halfshafts as both pointer fingertips pressed against each other VS. both pointer finger's knuckles pressed together (not the best examp but you get it)

FSTB's are more useful performancewise...bear with me, point coming up. Once you lower the center of gravity of the car, you'll barely feel the difference of the FSTB. Now, if thats true, what of the rear??

The gains from an RSTB are so close to nothing that its almost a placebo effect.

And thus my conclusion of the RSTB's being more for looks.


(I have the science in my head but can put it into words. Anyone wanna help me clarify?)

 

The chassis flex is from cornering forces, not vehicle mass. Chassis flex is independant of suspension design, as the chassis is decoupled from the suspension by the springs.

Rear tires do as much corning as the front tires (well, unless you're in a spin!).

 

First sentence contradicts itself. Keywords: force and mass. Mass is a part of the formula for force.

See Newtons Second Law. F=ma

Think about it: flexing wouldnt even occur if a car was so light to the point that when taking a turn really fast, that it'd just flip over. Has to be weight holding one side down and transfer of motion to wring the chassis.

 

title of this thread is misleading.. says ftsb when its for the rear.. either way "Bidding has ended on this item. "

 

No. It is Force that bends the chassis during cornering, not weight. See Newton, as above.

You've chosen to not answer why you feel the beam suspension design nullifies rear chassis flex.

 

I have answered that. See below. Its not fully nullified by having a beam but its next to nothing.

Once again F=MA

F- Force
M- Mass
A- Acceleration

Mass being closely related to WEIGHT.

 

Weight/Mass is half the equation of force. For example, what would have more impact? Throwing a piece of balled up paper at a wall or throwing a baseball at a wall?

So saying weight/mass has nothing to do with flex but force makes no sense at all. Thats like saying 12=7+5 is false.
