Skid plates anyone?

Postby marti » Mon Jan 19, 2009 6:04 pm

Just wondering if anyone out there is using any kind skid plate for rallycross. I've been looking around and can find some pre-fabs for imprezas, but not much along the lines of e30s. Looks like most of them are made of 3/16" or 1/8" aluminum and then talk about custom ones for stage rally. Anyone know a place in Lincoln to get cheap sheets of aluminum this size or what kind of material is used under stage rally cars?

There are some on R3V

Not sure I'm a fan of the design, but should be rather easy to pull off.

Something along this design would be better for rally in an E30 than the one I previously posted.

Old thread, but didn't see you post any resolution.

Here is what I did, just 1/8" steel bolted to the front subframe/core support. 3/4" square tubing to space it down a bit in the rear to clear the pan. It is really only suitable for light impacts, you could jack the car up with it, but the core support would deform on a really big hit.

I have a lot more of that material laying around if you want some, will also rent out my truck, 2x4 and crowbar to bend it. :D

looks good, hopefully i can avoid boulders enough not to worry about bending it :lol: how long would you say it took you to prep it and install? i'll be passing through omaha saturday to set up the course and can check it out if you got time.

It took a few hours, mostly because I don't have very good tools to cut and bend plates like that, it took some 'fine tuning' with the truck bending method to get it right, that was the most time consuming part.

I will be out at MAM saturday afternoon when I get off work (bmw DE weekend/ bbq), also sunday for the rallyx. It is really nothing fancy, but it works and has saved my oil pan on several occasions.

Thanks James!

The bmw thing is your typical HPDE lapping day, good fun. If you want to stick around for the bbq sat evening you're more than welcome, just rsvp to dana@equineforce.com . I think they charge a few bucks for a plate, but it's included in your DE package when you do em. Make sure to bring your helmet, can probably bum a ride with an instructor around the track if you're interested. :)

Be sure to wear your thick skin, some of those guys are very critical of 'destroying' bmw's by rallying them. :stop:

Skidplates are a bit overkill for soft dirt of rallyX.

That said, street signs make great skidplate material....

Image

I obviously don't condone stealing them off the street, the sign above was bought at a flea market for ~$5, seemed a little thicker than 1/4" thick, and is perfectly sized for most cars.

I made a quick cardboard template:
Image

cut the angles with a cutoff wheel, and bent the front lip up by whacking it with bodywork hammer and a piece of angle iron.

Image


I had one of similar manufacture on my lowered 240SX. While marshalling at 100AW rally, I came hauling down the road after the stage had closed, and one of the rally cars had swept a small boulder onto the road. The car in front of me hit it, and it came rolling under my car, punched a 3" hole about 1" in front of my oil pan. If I didn't have the skidplate, my car would have bled out on some rural road in the middle of the Ozarks. $5 is cheap insurance!

NO SANDWICHES! We have a six foot wide, two foot deep MONSTER grill with TWO tanks to initiate!

Call me, we'll work it out.
