You can Over-Strengthen a frame.If its' too rigid and doesn't flex,cracking will start where it wants to flex.Trust me on this,I've been around racing my whole life,and I build trucks for a living(stretch and shorten Heavy-Truck frames,install bodies).I've seen what happens when they are "Beefed" incorrectly.Keep an eye on it,and see how it holds up is all I can recommend.Hopefully all goes well,and you don't have any problems.
