Hey guys,
Finnally got a home, where tech is the only thing that goes here, non of that syracuse clown board **** here. Jammin runs a class act here.
INTRO:
Im a Pro-Stocker, run Fonda limited schedule, looing into a sportsman for 2005. I have had this itch mainly to cover myslef when the Pro-Stocks go extinct.. Im green in the N/E-Mod area, but not to racing, working on IMCAs and 3link pro-stocks, the potential for coil cars, link cars is there.
Wilson your about a season ahead of the ideas Ive had for a while on using a 5th coil, up front. I wanted to know if your still using the paired torque arms or a hiem mounted single arm LM style.

I'm currious how far off my thining and your actual doing this season is.
My concept car has:
RR floated Z-link or long clamped 2 link mounted parallel to frame.
LR short 2 link spring clamped ahead, or on a swing arm. torque arm LM style heim mounts on rear, right side of tranny, 5th coil, progressive spring, or stacked coils. damping springrate as determined.
LF side mounted J-bar, to get the effective roll center back to the left from the R-side due to the torqu-arm mounting.

Question 1: Do you really need the 6th spring for the braking forces, could this be mounted in a mannor to use a rubber mount in conjunction with the 5th coil. or even use a small cable on a chain. OR floated the brakes and put the force in to the chassis instead of the torqu arm..

2nd question: as long as ive been around mods, i can not under stand why the heck they make the chassis so tight that it takes 3-6" of stagger to turn the car. It makes sense to free the chassis up and tighten the setup back up by taking the stagger away, or better yet run the chassis tight and add the magical rear steer back into the car, an the driver can set the car for the ammounts of steer he needs, and better keep up with the track.....

Picture of torque arm idea. ignor the pul-bar also used in this photo. http://www.yager.net/hi-lineperformance/r-d/mod4.jpg

The picture of the cable mounted biscuit is another idea, found the picture on the web somewhere..

ok where to start. These cars are dewedged meaning only 45%-49% cross from rf to lr. The j-bar on left side is not needed. Dirt modifieds are tall and have alot of natual roll compared to the late model is very low so you need to vault chassis over rear. The torque arm with 5th coil is very hard to mount in a DIRT mod cockpit is very tight. The late models have alot of room for torque arms,shocks and coils, DIRT mods don't.
Hope this gives you some insight. Sorry to jump around abit.

Troyer has played with a lot of your ideas one form or another over the last few years and PMC has also tried the z-link style. Even a few have tried the 5 coil set up. But in all cases they have all went back to the TEO style due partly because no one wanted to work with it and make it better and itís a proven combo. Now I am not saying they will not work. To really get a new setup to work good you need a better part of a season to get it right most teams will not sacrifice that kind of time.

Q1) if you donít use a 6th coil and use a rubber stop it will shock the tires under braking

Q2) See Racerwilsons post

I believe in trying different things and get away of the follow the leader syndrome. There are still a lot to room for different set ups on these cars yet to be tapped. These are just my opinions.

Hey Cozmo,
I haven't been under a TEO, what type of "style" is under there...

A Teo uses a three link with low radius rods and a tork arm connected to a floor slider with an angled torsion rack. The Bicknell you are looking at has the same lay out as a Teo, the big difference is the way the cage is put together, it changes the way the chassis flexes.
