Sprint car build thread.

Next for the middle of the car.

The first thing you want to do is set your floorpan in place. There's nothing worse than getting the car on the ground and then realizing you forgot to put the floorpan in, which is pretty much impossible with the gear and driveline in.



Here's our favorite cheese man bolting in the rear motor plate.

rubber mallet and cussing!

Dude, that shit should just slide together. Check to make sure your splines aren't twisted or full of junk.

You're making this look easier than it really is. I know those torsion bars are bitches!

It really is as simple as it seems. Now, getting everything squared up and set right is a motherfucker, but putting in the bars is simple. How do you guys do them?

First, we'll start with the front end

In this picture I've got the pahard rod installed just to hold the front end centered in the chassis. Now, these axles aren't exactly centered up, they're offset 1" to the left side for the combination steering arm to clear the torsion arm.


Here you have the left side radius rod connected, its sole purpose is to hold the axle's fore and aft position.



Here on the right side there are two, which locate the axle fore and aft and set the caster angle. Depending on driver preference, caster will be set between 7 and 18 degrees, I like 12 myself.



Now it's time to put the torsion bars into place and set the ride height. When you square the front end, you'd use a 5" tall block, since that's done and we're setting up the race ride height, you use a 3" block underneath both sides of the axle.



And guys, don't forget to lube your bars before you put them in the tubes.



When you slide your arm on, you want the stop bolt (shown later) to be up against the pad, and the arm resting on the axle. Before you tighten the arm on the bar, you want to make sure you've got about a dime or nickle's width gap to allow the bar to move freely as the suspension works up and down.



This is a stop and stop bolt that I mentioned earlier, these bolts are what adjust the preload on the torsion bars, which act as the springs for the suspension. For those of you that are familiar with racing news this is the stop that came off and caused the wreck that took Jason Leffler's life. To say that these parts are extremely important would be an understatement.



And here you have the front suspension all together, save shocks.

Looks slow

[BMCSean]

Is there a way to make it "stanced"?

[slow06]

Awesome, this will be cool to watch go together. I go to the dirt track races in Kennedale every once in a while with my wife's family, the sprint cars are always one of my favorite parts.

[YALE]

Ok.

epic fail

God dammit! I moved the pictures to different folders and figured the links would stay the same. Calmate su chichis jotos!

[WesB]

Um, been there done that, but glad to see you're finally getting a car back together. Looks like if I want to work on a sprinter I'll be going to Indiana.

[idrivea4banger]

I'm not sponsoring this shit with my tacos.
