    I have ran 15-20 of them and won trophies in most of them. I only ran compact cars ( amc pacers, pinto's, spirits, mavericks, ect ). I ran a almost spotless amc pacer 8-9 times ( 4 1st places, 7 total trophies ) before it was too far gone ( I actually made money derbying it ). The wheelbase was 100" when I started derbying it and the last derby it was beat so bad it only measured 95". I took 2nd place in the last derby, my best friend beat the living crap out of my car ( he got first ). I never sandbagged, when the flag dropped my gas peddle was on the floor. WFO all the way!!! Had a special shifter I made that if I hit something with my front it slammed into reverse, then when i hit going in reverse it slammed into 1st. 80% of the time both my hands where on the steering wheel trying to control the car. I probably have 10-15 trophies.
    As far as welding goes, We only welded the differentials ( we weren't allowed to weld anything else ). It was great back then ( 15 years ago ). I'm not sure my body could handle the beating now, but if I get the chance I might give it another whirl. Got rid of all most my derby goodies. The only thing I still have access to is my special battery box. It was made out of heavy plate steel and took many direct hits and I never lost a battery. Other drivers wanted to know how I made it and what it was made out of. Some things you just got to keep secret. lol I was working on a Gas tank guard when I quit. It got used for something else. lol

    Here are a few me and some buddies did this year. I wish I had more of the previous ones but I'll post what I have.

    One me and a buddy did up, he took 3rd.

    Before:





    After:







    And one my other friend did that I rode in, he took 1st! Couldn't see out the back, it was pretty much a guessing game where the other car was. Put it in reverse and floor it. The only thing to hold onto was the seat, and we ended up bending the seat frame where we were holding on to the hard hits! The dent in the passenger door was where the other guy's bumper hit us once, his rear end was bent upwards worse then ours. That was quite a view!

    Nick, didn't you put a wire from the seat to passanger side front fire wall to support the seat? I normally put 6 strands of #9 wire ( 3 loops ) and then twisted them and wrapped them with foam and duct tape. I had 1 derby where we hit so hard we broke the wire ( 4 strands at that time ) and then the back of the seat. It's hard to sit up and hit with your backend when the seat is laying down. Front shots were the main hits the rest of the derby. lol After that we started wiring the seat from drivers door jam to the seat, and then the other side to the firewall. still broke a few seat backs, but at least they stayed up so we didn't laydown during the derby. lol

    200x, One guy that had seen the one pacer I had ( before derbying ) called me a couple years later wanting to buy it ( he lives 8 hrs away ). he said they are becoming collectors cars now. He wanted to buy it. I told him I had derbied it, but I did have a lot of parts I had removed.
    I went to a derby last year and the Mustangs seemed to be cleaning house. And yes they are highly welded now a days.

    No, we usually run 2" steel pipes from the floor to the roof directly behind each seat. Wire seems like it would be a serious safety hazard. These cars were literally 'day befores' (we didn't expect to run this time, too busy with B stock class) so almost no prep went into them. We have bent cars in half before too, in fact, we had a Subaru wagon that got T-boned from halfway across the field by a '69 Cadillac, car looked like it got wrapped around a pole! We straightened it out and ran it in another demo, it took first place over a 4 door Oldsmobile that time! It got bent so bad the middle of the car was sagging on the ground. Drove it off the track too!

    It's hard to tell in the pic, but the pinion on the rear axle is pointing nearly straight down, with the driveshaft still attached. You can tell by the way the 2 side doors fit, that's where it was hit by the Cadillac the first time and then straightened out. The drivers door still opened and shut too! The spare tire is also wedged behind the drivers seat holding it up. The seat broke in half after the first demo.

    Properly strung wire was actually safer than putting a pole behind the seat. i seen a pole welded behind the seat from the passanger door jam to the drivers door jam bend and push the seat into the steering wheel. The guy only got minor injuries ( bruised ribs ) but could have been a lot worse. We wrapped the wire with foam from the back seat 2" thick. You could hold onto it while driving backwards. Might not sound safe, but we never got hurt using it.
