I ran as high as 450/500 on the mod and am have run 600/650 on the l/m. Not the best on stop and go tracks, but on high bank or fast tracks its good. Makes the car real drivable.

I use a 275 on my left rear swingarm but alot will depend on the length of your swingarm as well. I run a 14 inch swingarm and the left rear is extremely soft. With the short swing arm I would try at least a 300.

we have had 400's across the rear at places like Eldora,Bulls Gap and etc like stated on an earlier post,high speed tracks,but for an average banked track,we liked a 350LR 300RR to start.

i've been trying the "high bite" setup and been changing the car a lot. i've run both j-bar and shorty bar and have both up around center of the axle with 2" rake and was still rolling over so hard it bottomed out the rr. i'm up to a 400# rr and 375# lr and had a tight car. we moved the front r/c to 2.75" up and 6" left and stiffened the rf to 1050# and the car really got fast.(too bad our seasons over). i would have liked to have tried dropping the bar 1 hole for the dryslick to see if it would bottom out the rr again. even setup this stiff the lf will come up about 2 to 4 inches, 4 to 6 if there is any hint of moisture. i run a fast 1/2 mile track that always goes dry.
