1000 LF 1100 RF
225 LR 200 RR
stock 1" front bar and stock 3/4" (or 7/8"?) rear bar.
RF shock is split valve, RR shock is light (really helped in weight transfer). Left shocks are 'standard' Afco's.

The car runs on a .588 mile track with decent banking and hard slick almost all the time. The first time I meet someone at the track they always say to ditch the bars. Then they watch it run and tell me to not change a thing. I'm a rookie in the car and have won 2 heat races and finsihed in the top 10 12 of 15 times with a best of 4th. So it must work ok.

Looks like their is still room for improvement Raz.Have you every tried ditching the bars both front and rear with the same spring combo?

Heard that one before.

A friend that pits next to me runs an almost identical car. He's trying this year with no bars at all. He's bought every spring between 900 and 1400 for the front and 150 and 300 for the rear. The last 3 weeks I think he's finally settled down and runs ok. But, he doesn't quite have the motor I do and I still can pass him on a good day... shadow him on any other. Basically, I have the car working pretty **** good for being a rookie and only like 15 races under my belt. I was in front of the track champ and current points leader for 9 laps in the feature last week until I f'd up and he got by me for 3rd. He was impressed enough that he sent one of his crew down to see who was driving the car.

Can't explain why exactly, but it just works. Not willing to spend all the $$$ on a stack of springs to try it without the bars.

Try ditching the rear bar and cutting loose the lf bar. Put a 1/2 inch bolt threw the stock opening witha large washer on top of the top bar and another on the bottom of the a arm. Double nut the bottom. Start with about 1/8 play when the car is sitting level. You can increase spring weight on the right side buy preloading the bolt on the left side sway bar. If the you put a reasonable preload on the bar and are still loose you can increase the sway bar diameter. The meteric cars have a few different diameter bars available. I was tould tha increasing the bar size buy just 1/8 inch is like changing the rf spring buy 200 lbs more. Try it its easy and you can fine tune with it. works for me.

ya... 1/8" makes a HUGE difference. I have a 1 1/8" bar until about 6 weeks ago. In a nasty wreck it got all mangled up and I only had a 1" bar to replace it. Actually, it's working even better now with the 1" bar and about 1"-1.5" more preload on the left side than it ever did with the 1 1/8" bar. We have had to play with camber and tire pressure on the right front, but some of that could just be from have to cut the front horns off the frame and everything 'springing' back after the wreck.

I've tried running with it a little loose and don't care for the way it handles. We top out at about 90-100mph on our track and it makes me feel uncomfortable going into the turns. Just too much chassis movement with the bars loose. I added the rear bar after 5 or 6 weeks of fighting bad handling. The car just rolled TOO d@mn much for my liking.

Maybe next year when I have more motor and need more traction I'll play with it. For now, I'm at least 3-5 mph faster in 1 & 3 than any other car on the track. They just pull me on the straights 'cause I built a 'beginner' motor for myself this year.

Ya Bob.. I heard about that one.... Although... wasn't it a 383 or a 406? Runnin' that against a 355 isn't quite fair. Just bustin' yer chops. I think it's mostly a driver preference thing. I wish I had the money to finish the 406 this year. I would have really liked to have had it for Raceway7, Challenger, Tri-City, PPMS and L'ville's end of year races. Instead I have my 'rookie' motor that's seriously outgunned. We'll just haveta see. Good luck and see ya next weekend.

Haven't been to Challenger yet. This is my rookie year in the car.. I'd been the part owner/engine builder/sucker with money for the last 2 years. We built a new car for my partner (that's been pretty much destroyed and is in process of having half the frame replaced) and I've been driving the now 3 year old car with quite a few used/spare/leftover parts. I'm accumulating parts for a better motor and wheels to run at tracks other than PPMS and Tri-City. Next year I might travel around a bit more...only time will tell. One of my friends that will hopefully be helping me more next year (both time and money) loves Challenger. He used to go there with Fred Bratchie, so he'll probably make me go there at least a few times if they start running every week again.

Challenger was great for Summerfest. They made run off areas that stretch from turn one all the way around to turn three. makes the track seem bigger. its not any different but there seemed to be more guys willing to try the topside of the track. i had some bad luck but we still came out of there happy with the improvements. we've also been to hummingbird, i really like that place. tough little track, great competition. challenger was my home now we run at lernerville, been to gamblers a couple times, marion center, planning on running mercer this week possibly latrobe (i really dont like that place) pittsburgh is going to get rained out, thats where we were headed.

Yeah they really needed to do somthing with that drop-off. We had to miss the SummerFest but plan on being at FallFest.
Hopefully a little better weather than last year.
