rc8t rc monster chassis

so i bent the crap out of the first chassis i purchased here, my fault 5s 2200mmm combo drunk as hell with a 4ft high jump... good times.

bought a second and upgraded to the thicker front and rear chassis brace the blue pure alum ones http://cgi.ebay.com/Associated-Rear-...item255d76ce12 this is just the rear got the front as well.

not sure that important, but can someone tell me if there is any angle on the rear chassis where it gets thinner from main body of the chassis. if i hold a straight edge up to the bottom of it i can see a sliver of light near the rear of the chassis, am i doomed again?
thanks all
