dON'T BE TOO SCARED TO RUN YOUR REAR PERCENTAGE TO 60% WITH THE IMCA TIRES. FURTHERMORE, THE LEFT REAR BITE SEAMS OK BUT I HAVE FOUND THAT THE IMCA TIRES LIKE ALOT OF LEFT REAR TO HOOK UP. YOU ALSO MIGHT WANT TO LOOK AT YOUR PULL ROD TRAVEL. CHANGING THE ANTISQUAT % WILL MAKE A DIFFERENCE.

The 400/1000 pullbar spring is more for a 2 link set-up its made to coilbind the 400lb. part then gets into the 1000 lb. part.Go to a 900/1300 or a 1200lb. pullbar spring for the swing arm you'll have a lot more bite.the 400/1000 takes to long to compress to do you any good.

I am running a 900 afco torque link and i get 2 1/4 movement with a 406 and i have thought about stiffening mine to see if there was any differce but i am going to a smaller motor what do you guys think i could use a little bit more bite ,

Usually,more pullbar spring will transfer more weight to the rear tires from the front end.I've seen swing-arm cars use a solid bar on tacky tracks and big 1/2 miles with great success.Also more crosswight is also a good way to go.

where are your springs mounted at are they on clamp brackets or on the birdcage?If there on the birdcage I'd still go with a stiffer pullbar like a 900/1300 or a straight rate 1200.If you have them on clamp brackets,a 600/1200 will work also I have seen a 600/1200 go good if your springs are on the birdcages if you preload it about an inch.
