Default Removal of diagonal crossbar that connects to rear bulkhead.

I have a hobao hyper8 and I want induce more flex in my car. ( I want more grip at rear ).

Is it safe to remove the diagonal crossbar that connects to rear bulkhead ??

( For non hyper8 owners : I would like to tell you that hyper8's radio box is already bolt on flat to chassis with four screws. So, I think the radio box could help stiffen the rear section of the chassis where diagonal crossbar is absent ).

Thank you for giving me inputs.

you wil experience some radical movement when you take that bar off.. that is what supports the rear of the car and chassis. be prepared to change cb bearings more often also from all of the flexing of the chassis. i would try to find a plastic one to put on there and that will help some with more rear traction..

you could stall the engine when chassis flexes that much with no brace at all that the flywheel touches the brake pad screw and stops it rotating, and maybe break screws out of bottom of radio box, both of these things happened to me lots of times with an old thunder tiger mirage buggy that had no brace

It would be best to leave the brace on or get a plastic one but not sure if they make a plasic one for the hyper 8.

If you are having that much rear traction problems, its not your brace!

Check your tires, your toe, camber, castor, shock set-up, and rear ride height and droop. Play around with some different set-ups to get more rear traction. You may also need to go up or down in the rear diff oil, depending on your engine and gearing.

I would think something is either broken, or not set up correctly. You are the only person I've heard of that is having rear traction issues. Your rear diff may be stripped, or blown, or the bearings are shot.

It's not a good idea. Chassis braces serve a huge purpose, and like I stated above, if you are not getting enough rear traction, its not your brace

As everyone mentioned above it will greatly increase the chassis flex. This will affect gear mesh and could all bend your rear drive shaft if it is jammed into the center diff.
