Strengthened Engine subframes

[Gmtech1005]

I am considering taking firebird subframes and reinforcing them to help stiffen up the front end a little bit, kinda like a strut tower brace, but for the lower section.

Wouldn't make sense for the front end...you have the engine crossmember there that connects the frame rails so what would be the purpose?

not only that the after market k members

the convertables do something similar on their crossmembers, I don't fully know whether it is to stiffen it to make up for lack of top, or what. Idunno really, I am putting a v8 into my v6 and the only k-member I could get my hands on was a v8 conv. I compaired it to a v6 coupe k-member, and there are 4 bolted on bars. I am gonna chat with the Ford SVT engineers on monday and see what the deal is with them. I know they aren't gm, but I work with them so hey, why not. I'll post what they say

plus, how am i supposed to see the results without voting...It doesn't make sense for me to vote...I asked the question

[Gmtech1005]

The 2004 cobras use a similar set up, but theirs is a subframe attachment piece. They said it is a frame tie, and basically helps stiffen the frame to avoid unwanted body flex.

Now that i have voted here are my comments. I think that anyplace you can find to stiffen the structure of the car is going to show a all around benefit.

However, you have to be carefull with bracing/strenghening. Stiff and light = good. Stiff and heavy as a truck = bad. This is even more important with unsprung weight.

I agree...it is 4 simple bars welded into place, maybe add 1/4 lb at max, so weight souldn't be bad.
