rear suspension arm

[robsm]

Had my 22 rtr literally 10 seconds and the rear arm broke, cant beleive it. Very low speed knock from another car, my 22 wasnt even moving. Glued it back together but only lasted about 3mins before it snapped. Not impressed with the quality of plastie. Are there any stronger options out there? This really was a very low speed impact, and for a car with such a racing pedigree i had expected better. Any advice or should i just replace with stock parts? Cheers
