We have heard that TEO and Troyer are recommending a .925 bar on the RR but we are hearing rumors about guys going up to a .975..
I get that spring rate =traction but just going up over all???

Darin I have a torsion bar rate calculator i got it from troyer.
I am at the moment using a .875 bar on the right rear which worked out to 123lbs per inch of spring travel.
when i came to the States in 2003 the guy i crewed for was running a .900 bar in his Teo, So when iworked out what per inch of spring travel it was 90 lbs That was REALLY SOFT!!!!! rob.

Two years ago alan johnson brought his small block car to eastern stastes. I had a flashlight and went and checked out the bars. A pair of 975 in the front holes . This was his fulton car. Bicknell torsion arm length at the roller is almost 1''shorter than a teo. I know of guys with bicknells at middletown with a 925rr 975 lr both rollers back and winning. I really think you get to a point where you go softer AND LOOSE BITE. The bar has to be stiff enough to plant the tire. I also know of guys with teo's in the past winning with a pair of 900's in the front holes. Late model guys stiffen the rr when they are loose going in??????????

We are using a .950 LR and a .925 RR...on 1/4 mile pretty flat tracks and just can't get the LR heated up like it should...Not really loose off but not the grip we want...We are wondering if the .975 would be the ticket.

I would think a .900 r/rear would be better

if you can afford to loose a little side bite going in go with a .925 lr bar.. A stiffer lr makes for more side bite and less foward bite. Also if your looking for more bite from the middle out try an easy out lr shock.

Ez up LR will allow the car to turn in easyer and gain sidebite. By going to an Ez up pair of front shocks will give youthat rear % for fwd bite.

That would be cool. I've only seen some clips of your racing. Our std shock is Bilstien 162-55 for front and 208-72 for rear. An EZ-UP on front would be a 120-55 it has less rebound so it will transfer more weight to the rear with out having to add weight. On the left rear less rebound would allow weight to transfer quicker. The shocks are your chassis timing controling weight transfer. A tie down wold be a heavyer rebound holding that corner down or slowing it up.

wilson i was looking them up in the Bicknell catalog and they list the basic ones.(BILSTEIN SHOCKS)
And they are not on the shock cross reference table.
I was sort of hoping that i could get an afco/pro one that was similar to the bilstein at the moment i run QA1 shocks and pro A750 across the front r/rear 95/96 depending on track and l/rear a956 tie down
