DSE T56 Crossmember

[mazspeed]

I have a silly question to ask. I have my TKO-600 but I want to use DSE's T56 Crossmember to add strength to the car. Crossmember
What do you guys think? I was debating a cage but the guys at CARR think that I should go without one and use this to help beef up the chassis a bit. I agree that I don't really want a cage as the interior is really first rate and I don't want to disturb that, but Ill be running over 600hp and want to stiffen things up as I will be running the car hard at times. What do you guys think?
I'm going to ask this in the camaro forum as well as it's pretty camaro specific.
