Default 1G skidplate?

Has anybody ever built there own rallyX capable skidplate? I'm a CNC programmer by trade and not a stranger to fabrication and metal work. I'm thinking about buying a 1/4 inch sheet aluminum and having it water jet cut out and making brackets to mount it. I'm already working on a tubular front bumper to support the IC and mount fog lights too and I may use the bumper as a mounting point as well. What say you? Unnecessary or will it keep the bay a bit cleaner and protect the oil pan?

I made my own a couple of years ago. 3/16" is plenty for rallyx, and I've found that the rad support is sturdy enough to mount to as well. I'm FWD so my crossmember setup is different than yours, but I've got a couple 9/16" grade 8 bolts with some thickwall spacers straight up through the rad support and then a single square u-bolt slung over the center crossmember to hold the rear up. Also recently added some offroad bolthead protectors just to be on the safe side. The two biggest things to think about are keeping the front edge from catching on anything, and to make sure there isn't enough flexing room for the plate to be pushed into the pan. I have mine mounted far enough back that the rear corners bump into the subframe around the front LCA mount, but the crossmembers on then AWD car are positioned in such a way that they'd do this themselves. I also picked up a tip from Team O'Neils to put a block of thick foam under the oil pan so that rocks can't get trapped under it and punched through the pan if you were to hit something right underneath.

When you're designing your mounting setup, try to use as many through-bolts as possible (you don't want bolts snapped off in inaccessible threaded holes) and to oversize all of the mounting holes in the plate itself.

I think it's definitely a worthwhile modification. Put a skid plate on and then you can worry about the course in front of you instead of worrying about puncturing your pan.

Awesome looking skid plate and I love the decal Sam!

Thanks Sam those are all awesome pointers especially the foam thing! I'm remounting my turbo tonight and then comes the skidplates and tucking the exhaust a little tighter.

No problem! Just a note for you about the foam under the pan--I'm N/A so my exhaust temps don't worry me at all, but you may want to consider some sort of heat shielding or wrap if you go that route. The type of foam I used was the charcoal colored packaging foam which has a flash point around 5-600 degrees IIRC, but a turbo downpipe that's enclosed by a skidplate might start to worry me. Most of the AWD plates I've seen on peoples cars sit much lower than mine does, so you'll probably have plenty of clearance anyway and not even need to consider it.
