Hey guys, I'm a rookie in sprints too. Lookin for a little help. Anybody know anything about coil cars???? Im running a coil/swaybar front and a bar rear. We usually run 12-14" of stagger in the heats and qualifying and around 10" for the feature. We had some awesome setup help from a pretty good USAC/CRA driver the first night out and made the show. his old car so he was helping us out basically set the car up for us told us everything we should do. we keep making the car better but it seems like we aren't there yet. 12th in semi second week. 10th in semi third race. 7th in semi last weekend. the problem i am having is changing the car to the track. In the heat race the car is constantly too tight and stays wheelied up we have changed rear bars, moved the right rear out as far as possible ran as much as 17" of stagger and it felt like a band aid it actually wanted to spin out with that much stagger on a heavy racetrack. then we go to the feature and we move the right rear back in add fuel take stagger out and the car is WAY too loose. with this coil car do i need to be making extreme changes between the heats and mains? I was lifting both front wheels in the heat last week so we moved the right rear in 1" and left the rest alone the car was decent but too loose. It's tough to come in after looking up at the sky for 8 laps and go "ok lets tighten this baby up." anybody got any ideas? I'm thinking stagger. last week i looked at a lot of the cars in the main and the most stagger they had was 8" the only other coil car there had 3" Most were running 4-6 though. sound like the right place to look? by the way 44H i still say you stole my name.

by the way its non-wing and the track usually dries out between our heat races and the main.

what spring rates do you have on the front? I'm thinking of converting my car to coils on the front this winter and trying it. As far as setup help, with the little knowledge I've got, are you putting any turns in anywhere? My winged car I'll crank LR weight into the car as the night goes on along with adjusting wheel spacing. I dont know if this is correct but it has been working for me....brought home a 3rd place finish in the A last time out!

we run 225-lf 275-rf. I think the combo cars are the way to go. But thats just cause i grew up watching JJ Yeley spank everybody and there mom in em. All I am hearing right now is about why i shouldn't be running one. The only other coil car here is 2nd in points and isn't really interested in giving setup tips to rookies. I don't blame him, he had to learn by trial and error. We ran last night and the car was WAY better, ran a whole lot of stagger (13") with the right rear sucked in. started last in feature got into a little incident passing for 13th the 12th place car spun in front of me and i clipped him with the right rear, 6 laps later the tire went flat while i was running 11th broke the jacobs ladder too. Still most fun i have had in a sprint car, it was hooked first time the car would actually rotate in the center and still lift the left front coming off. congrats on the 3rd place Where do you run, what sanctioning body/association is it?

not jacking weight around at the track. gonna try though this weekend.

i just run at our local track. We use NCRA rules which is the same as ASCS except we are only allowed to run a hard RR and medium LR.

I had my hands full this weekend. I missed the setup bad for the A. Started 3rd row inside and fell back to 11th. Car would not rotate in the center. Between that and the motor getting up to 250* I was concentrating more on the motor temp than driving. Oh well, it's still in one piece and there's always next week.

if its way tight early , way loose late , with out ever having it seem good I would suggest either one or more of the following things are bad/ bound up/ cracked/ etc...
bars in rear...any shock but rears mainly...chassis cracked or broken in one or more spots... torque tube and ball in serious bind ... bent t tube ... snout on rear bent.... torsion tube bent and binding on bar..... and any number of potential things... but if it were me, i'd get my baseline set in stone for that track, then do what you know... dont go drastic, after you verify all things are 100% on the car. and if ya don't have it, get it, the steve smith book. and make all numbers like he says to make them on squaring, etc..

No the car is awesome at times. Most of the time for about the first 5-6 laps of the main, when the track is still good the car can be VERY good but the slightest change in the track surface seems huge.

well, and it may seem harsh , but ya gotta just basically learn to drive the car over a wider margin of error so you are better longer than 5 or 6 laps... I suppose if it was the last 5 it would help, but by then it wouda been way too late. also, don't try to nail the setup so spot on.. you need to find a setup that is maybe a bit more forgiving and a bit more consistant over a wider variation. thats all I can suggest if all else is good and square and free in the car itself.
Do they allow adjustable shocks from inside? if so, i'd invest in at minimum one, maybe 2. rf for sure, and maybe a lft front. leave the left rear tied as tight as you can in my opinion on wingless for sure. like a 3/9 or 4/9 or even more rebound than that in certain situations ...
5 compressions w/ rebound adjusts up front would be ideal.....
but ya know...

Thats not too harsh, thats what I am trying to do. The first time in the car we made the show and got to run 40 laps on a track that was SUPER dry slick to start but started to take rubber about the last 3rd of the race it was definetly a good experience. I hear ya though, we have tried the 3/11 on the left rear when dry, makes a huge difference!... put it on the right rear when it was tacky and the car seemed to rotate WAY better but... after about 10 laps the track wasn't tacky and we were spinning tires. cockpit adjustables are not allowed but you can have adjustable shocks (you can adjust them under red but they can not be reachable from the cockpit). thanks for the tips.

the heavier the track is, thats when you use the stout tie down on the left rear. as it slicks off let it lift slightly, but wingless I wouldn't go lighter than a 3/8 ever. as for tie downs on the right rear, I pretty much use a 6/5 at all times and just kinda forget about it. if ya had a 6/4 you could use that when it slicked off, but i'd never run more split than that in the right rear, will hit a bump and pack up, thus causing the wheel to leave the ground, after that it just gets progressively uglier. basically keep the front and left as stable as possible early, then as it slicks off start freeing them up with the track is about the easiest way to explain it in my opinion. it still is all preference and style and what YOU can make work for YOU...
grin and pin it....
