how much flex is to much?, hack n wack it Options

[the4u2]

How much flex is to much? I have one that flex 8mm ,I cut up any tub that flex over 14mm (IMG:style_emoticons/default/sawzall-smiley.gif)
Will a chassis stiffening kit fix that much flex (14mm)

Thank you for any info

covering up the hell hole is not a FIX!! And dose not stop flexing at ALL!

Where are you measuring this flex?

Corner to Corner?
Suspension points?
Doors?

The three places I mentioned have a variation of up to three feet in dimension so it really would make a difference where you are measuing the flex.

Given that, all cars flex, even new ones.

the chassis Stiffening kits was designed for race cars with really stiff springs that were cracking the outer longitudinal right at the rear shock tower. This is because the shock tower was not welded to well in that area and all the vertical load ends up on the outer long....mainly in one place. If its cracked there or flexing there, then yes it will help.

The longs also crack directly under the windshield (drop a plumb bob from the top edge of the windshield) and that area also cracks.
The Engman inner longitudinal kit will help fix that flex and will stiffen up the car quite a bit.

For the standard hell hole issue there is no way to do it half ass and have it last. You need to remove the outer long and inner rear fender and replace them with new metal. If what you have is no rusted to bad, you can buy an outer longitidinal overlay (not stock) that fits over the whole long, from the front inner fender to the rear suspension mount...
That is the best cure for the flex...adding extra metal.
