Default Mtx 3 bumper warping,limiting suspension,any fixes?

I have the long bumper and after a while it starts to dip at the ends limiting suspension travel.I installed a graphite brace along the top but it still bows a little bit.Should I just cut it shorter or any other ideas?

Everynow and then, before every race, i would just bend the warping side upward with my hand, to avoid getting close to the ground. The plastic upfront is soft, i guess the idea is to absorb as much impact as possible, and end up warping the bumper.

hmm...Maybe i should try the smaller one.

My fix might not be pretty but it works for me. I drilled a small hole at each end and tied it to the body posts using fishing line. It maintains it with a small curvature upwards.

just use the smaller bumper since the foam bumper should
absorb most of the impact. and will not affect ground clearance
as related to the chasis clearance.

I took mine off a couple of weeks ago while I worked on the car. I took the bumper and bent it so that it would fit in the drawers of my (tackle) toolbox, after a half hour it was re-shaped so that it no longer dragged the ground.

Default WOW Sounds like the MRX issue

What I do, is heat it in hot water(boil it). Take it out, stick it in a vice and flex the wings up while it is still hot. ALSO, if you stick a couple washers between the top if the chasis plate and the bottom of the bumper it'll buy you a few mm's as well. Never had the prob with the MTX but man did I have it with the MRX.

Yeah boiling the top and bottom plate works, just straightened out my whole front end. I wouldn't say it's an "issue". Hit the wall, something's going to give. Thankfully this technique will get more useable life out of these pieces.
