I have a 98 Harris/3 link. I am looking for suggestions for dry slick. I have tried about everything and still can't get off the corners with the 4-bar cars. Right now I have 650 lf, 750 rf, 175 lr, 125 rr. both rear springs are on top of rearend housing. Short panhard bar mounted from left of pinion to mount on left of frame, 11" long from center to center. lr lower arm in 20 1/2" and right side is 20". The pull bar is a long one which is at about 18* with a progressive spring with a 1/8" of preload. The left side has a brake floater and the right side is clamped down. I am pretty good getting in to corners but struggle getting on the gas thru the middle and coming out. I had another driving tell me to shorten the left side lower bar. Can anybody help me that has experienced this and fixed the problem?

shorten the lr lower link with a plug till it is like 12 inches, then put the lr spring clamped up in front, and like 225 spring rate, step up the rr to 175
put on a short panhard bar, about 2nd hole up on pinon and 3.5 inches of rake upward to frame(frame point is higher than pinon).
this should help you to get on the bars faster and get the car bitting more on dryslick.
goodluck

Take the other drivers advice and put in a shorter left link !.....to do this you will have to fabricate a plug that extends the left mounting point ,make the plug so you can get from 5 to 20 degrees ....with a 20 inch right side you want about 14 to 16 left side link ( the shorter the quiker it will get up on the bars)......this set up has worked well for me ,but it took some getting used to .....you can get lots of roll steer and pull the left front way off the ground .....I run my left link at 16 * and my right at 12* my short pan bar is 14" longt and I have it even with the pinion and at about 15 degree angle......with it like this it is three wheeling pretty good on tacky heat race track and settles down and driving hard and fast on slick track ....dont change much between heat and feature ,I just let the track come to my set up....good luck .

Ok, thanks for the help. I have other questions. If I do shorten the LR arm is 12" or 16", which length should I do? Will my front springs be ok 650LF 750RF? My pull bar has a progressive spring, will it be ok? And my biggest question is the plug to shorten my LR. What is a plug? Can I buy one or do I have to fabricate one and if so how do I do it????????? If I have to fabricate it I need to be walked thru it. Any Help!!!!!!!!!!! Thanks

I cant answer about 12" mine is about 16 1/2 "and works well.....the shorter you go the faster it will react......a plug is nothing more than a bracket that bolts to your existing mount to move the bracket closer to the rear end......build the bracket and choose the appropriate length linc ....square your rear end and go get em.....I run a progressive pull bar with lots of pree load ......do a search in the archives on plugs ,or chassis plugs there has been lots of discussion on how to build them....or start a new thread on how to build them.....good luck.
