I'm pretty clear on the notion of building a sturdy frame for the skidplate.
What I've never quite gotten - what's the preferred way to attach the skidplate to a frame? The obvious is bolt heads sticking out, like so: But that seems like you're just asking to have the bolt heads beat to smithereens. I've seen some "clever" approaches using stuff welded to the top of the plate, but those seem like they'd be a real PITA to remove. Seeing the latest Ken Block video this morning (seriously!) prompted me to do a little more searching. Looks like lots of folks are basically just counter-sinking them? <<Seriously, video grab from Ken Block Seems like it would be simple enough to weld a second piece of aluminum on the back of the plate, drill the oversize hole through the first piece and the bolt-size hole in the second? Maybe not as fancy looking as the video capture, but the same functionality, no? KF7RWG http://www.utahrallygroup.com |

My favorite setup so far:
two bolts on and off. -Tom DemonRallyTeam | Fine Tuning | CTS Turbo & RP Turbos | RalleyTuned | JRM | Meister Autowerks Spitfire EFI | Product Apparel | JVAB Imports | NLS | AP Tuning | USRT Add us on Facebook | Next Event: 2013 Olympus Rally June 22-23 Olympia, WA |

Find a piccie how Sean M used the Soooper bitchin "606" method.
I don't like this fad of having the leading edge of the sump guard exposed. I like to lay it in the inside of a L angle running across the front secured to sturdy side mounted plates to dissipate loads out into something strong, like the chassi rails But what the fawk do i know anything. Those eople who caught to forward edge and peeled back their plate and ran over it and high centered and DNF, that was a freak accident, and act of Gawd.. Don't worry, live on the Wild Side.

So you've got the alloy supports bolted to the chassis rails. The square tube crossmember bolted to the alloy supports. Pretty sure I'm clear on the support for the sumpguard. Looks like with that kevlar setup, it just bolts straight in to the crossmember, bolt heads just hangin' out? That's what I'm trying to understand.
something other than the long upward-sloped piece like the BMW in the first post? KF7RWG http://www.utahrallygroup.com |

OK Sean used square section and it was also a bumper mount thrown in, I'm say take a L angle and lay the leading edge on top of the horisontal part of the L, and bolt thru...pretty hard to catch that leading edge when theres a steel L piece protecting it..
And of course if you can counter-bore mounting bolts so the heads are below the surface... John Vanlandingham Sleezattle, WA, USA Vive le Prole-le-ralliat www.rallyrace.net/jvab CALL +1 206 431-9696 Remember! Pacific Standard Time is 3 hours behind Eastern Standard Time. |

And no fucking around playing "throw the pizza dough" while trying to line everything back up while putting it on, either. That picture up at top with the angle grinder - SPARKS? Meaning that sucker is STEEL? I thought I was the only person dumb enough for that. Pete Remner Cleveland, Ohio 1984 RX-7 (rallycross thing) 1978 Silence is golden, but duct tape is silver. |

ALL steel and iron is approx 7.9 to 8.1 g/cm3 aluminum is approx 2.7g/cm3 And just for fun, magnesium is about 1.7g/cm3 Bear in mind you never use 100% pure aluminum or magnesium, both are slightly stiffer than old used taffy, most aluminum is 6-105 other stuff and most magnesium is 20-25% aluminum---both alloy with copper and somehow some of the softest metal around becomes stronger than shittier grade of steel (like the steel wheels are stamped from). Material thickness becomes a significant factor...3 times thick sound horrible but the right aluminum 3 times thicker is stronger than the wrong steel at 1/3 the thickness.

It can be. Talking with the Msport guys working on the v1.0 HFHV when I was in the octane academy, they said the front and rear skid plates are steel for ballast reasons. They even have mounting provisions to put more ballast weight on them if needed. They basically design the cars to be underweight and then add ballast for balance. I think that Antony worm guy mentioned it as well and was a sign how screwed he got as a customer car. Where his car had AL skid plates and was still over weight while the factory drivers had steel skid plates with ballast. |

Saw this today, pretty cool info, and a crush zone idea that I thought was really neat!...but most of you probably know all this stuff already
