I bribed Santa $700 and he delivered early.

I'm a guy who learned to race on a tight budget and learned to fabricate most of my own stuff.

But, sometimes you have to yell "Santa"...err I mean "uncle"!!!!

So I pulled another trigger and got my original chassis builder to send out his latest, updated front crossmember and four bar brackets.

This, and another $20K, will make car competitive.

Making the driver competitive is another thing altogether.

Got a installed picture?

Send me your magic wand!

Next up find some directions.... Likely have to make them up as I go...

looks nice. what did he send with it, a post-it that says "weld here-->"

Said ”good luck" on the invoice!

Actually the install is pretty ez. You just need a plumb bob, a square, some dyekem, a good tape measure...stuff like that.

I'm replacing the existing two front crossmembers. One goes in the same spot...one is moved back two inches from the existing one.

That's all done to raise the x-members to keep the front end from bottoming out with these newer front end setups that are used to help the race car turn.

The rear brackets give a much closer set of holes for adjusting the bar angles. Those adjustments adjust the traction available on each rear tire.

Together the front and rear ends of these dirt cars are setup completely foreign to what I'm used to. But the old setups won't let you keep up with the newer cars. At best this is a bandaid to make an old car a bit more competitive.

I was going to stand my ground and prove these other guys wrong. But, after hanging around the pits the past four years, and crewing on my buddies car for two seasons, even an old hard headed bastard like me can see the writing on the wall.

Think about this...
You set the car up to let the LR raise up on acceleration (maybe 8")....and run a soft 225# RF spring that shoves the RF tire into the dirt (we used to run a 600-900 in the RF). That deal allows the car to steer on the RF while the four bars jam the LR into the track.

Hardly makes sense but it works.

i'm always amazed to see so much non-electronics evolution going on in race cars. you'd think by now it would all be down to tires and driving

The fast guys are using data loggers to get chassis info during test sessions (not legal while racing btw) and now the latest tech uses pull-down rigs to simulate the car in racing form so changes can be made and you'll get instant feedback. Not cheap. I've heard renting a pull-down rig is about $400/hour. Way outta my league.

Here's a some what older video of a dirt late model with a fourbar/z-link hybrid suspension. If you look at a modern car like this the top left bar would be almost vertical driving the rubber into the track surface.

Were you asking about the chassis mfg. (Dillon)?

Dillon is no longer in business although Ray Dillon built a heck of a lot of cars... mostly pavement but some for dirt.

This is a Mastersbilt. They are built in Coruthersville, IN. It's an '03 which is ancient by most standards but there are still a fair amount of older cars running weekly shows. Today a lot of guys don't run anything more than a few years old. Some just buy a complete new roller or turn key car. Some just get a newer chassis and reuse most of the old bolt ons. I have been buying 90% used parts as I don't have any other choice.
