I have just been able to accomplish a dream of mine by buying a 1978 Camaro that has been run in the past in Colorado on asphalt. I'm not knowledgeable in the differences in the setup of a car for asphalt versus dirt, so I'm asking you guys. I understand that the shocks and struts need to be changed, but I wanted to know what might be some recommendations as I don't really know much about that stuff. I'm more of a Cole Trickle...I can drive, but don't ask me about fixing it. I'm trying to learn that part right now. I wish that I could just find that female cop that frisked up Tom Cruise in that movie. If anyone gets pulled over by her, let me know. I'll run through her speed trap every day. Thanks, guys.

raise the ride height, take out the windshield, put some more wedge into the chassis and let her rip. I think the struts will be fine...once you are done with that patrolcopette!

if your fuel cell is 4 inches off the ground like the cells on the pavement cars ive seen, theen move it up, we allways mount them as high as we can. what can you tell us about your springs, and what kinda track will you be running?

I'm not sure about the springs, yet...haven't had much of a chance to look at them yet (just got the car this weekend), but I'll mostly be running at I-76 speedway in Ft. Morgan, CO. It's a 1/4 mile high-bank dirt track.

A 78 Camaro shouldn't have struts. It should have conventional 5 1/2" springs in the front with conventional shocks and leafs in the back. Most of the dirt cars I've noticed do some or all of the following different from pavement:

Higher ride heights
Slightly stiffer springs - more front split
More rear weight percentage
Less left percentage (not sure why)
No sway bar - stiffer springs to compensate
Maybe nerf bars outside the doors if needed

I run a '80 Camaro on a high-banked 3/8 mile that is always tacky. Car must weigh 3,200 lbs with driver before race. Believe this or not, but I run 1,800 lb/in rf spring, a 1,600 lf, a 200 rr and 225 lr. If I go any lighter I end up bottoming out the rf.

I'd bet your springs (at least the front) are no where near this stiff. Also, be sure to check with your class rules at the track you'll be running to make sure if weight-jacks and other suspension mods that may be on the car are allowed. It would be a shame to put a bunch of work into it and not be able to run.

Jesus Dixon, why not just use wood blocks and go solid? I tried 1300 rf and 1000 lf once at a banked 3/8 mile and it about knocked my teeth out, although I did feel fast! I ended up with 1000 rf and 900 lf.
What's your front ride heights and do you use spacers?

Milot, trust me, this track is banked to the sky. It never fails that someone in the infield has to have their hauler and all pulled out by a tractor. The announcer makes a big joke out of all the folks who fall down trying to walk down to the pits (it happens quite often). The only problem is that the track is so steep, it's hard to run a grader and other equipment on it, so it ends up being real rough. You ought to come check it out--Tazewell, Tennessee--it's a blast to drive.

I started out with a 1200 rf and 1000 lf, but kept inching up, until I learned that EVERONE was running between 1600-1800 on the rf.

Been there--done that! That is the fastest (bar none) track I know of anywhere! Pure streets turn laps in the 15's and Mod streets in the 13's. 3/8 mile hole in the earth! Fun!
