Subframe connectors question?

I posted this question in another thread but I don't want to hijack so I'll start this one.

Are there any drawbacks to heating up the subs to mold them with the contour of the under body? I mean, cause I have clearance issues and I can't give up any room down there. Check out this pic from BensCobra:

this is why i still have stock springs

I did too. Roads here suck. I finally got tired of EVERYONE telling me to lower the car. Put uncut drag launch springs on the car. Now when a punk makes a comment about lowering the car. I reply "it has drag springs on it."

They usually reply.... oh, then that's okay. :rolleyes:
