Do SLP bolt in subframes dent the floor boards? I've noticed a lump on my drivers side floor board a little infront of the seat. Pretty sure it wasnt there before and I dont think I've hit anything against my subframes?
Thoughts? Oh and I havent had a chance to look under yet.

My '99 hasn't had subframe connectors installed in it yet, and I have a similar lump in the floor. Not sure if it is a seam or what it is, the underside of the car appears okay (no unusual curvature of the floorpan or frame rails).
Your car hasn't been wrecked or anything has it?

That "hump" was there since the '93 LT1 cars to fit the single cat that used to be in that spot.
Even when the dual cat LT1, then LS1 cars didn't need that space, the factory still had the hump there, it has nothing to do with your subframes, SLP, or any other.

I have SLP bolt ins which were also seam welded. I have not noticed anything like what you're mentioning, even with hitting the subframes a few times (they actually saved my rockers/sills a few times [lowered car]).
