Basically that just makes for rear steer "gain". Because the shorter arm will have a tighter radiused arc than the long arm it will translate the axle fore/aft more and quicker than will the longer one.

hope that helps, and isn't too confusing. I'm good at confusing people.

I've been through this before.

We ran 21" swingarms for a while then we put the a 12" swingarm on the LR and it helped, but was a little hard to drive in traffic, because the car was hooked so tight. LF was a foot in the air.
Then we went to running the RR only 1/2 inch or so longer. Car went forward, also kept the LF on the ground a little more. As far as dry slick tracks???? It went alright until I got aquainted with the 1st turn wall at lakeside. The Jet car we have now had a z-link on both sides, now we have the 12" swingarm on a soild clamp on the LR, car gained a ton of forward bite. Anyway....what we found was that the shorter lower links work well to a certain point, i would say anything much shorter than 14 to 15 inches would be nuts to drive. Afco is where we came up with the short swingarm. And it sounds like you are from mid missouri, so i would call John at Dyer's performane specialists in Oak Grove, he's who answered my questions when we were doign this same thing. (Him and Chad Lyle are pretty good buddies) They also carry Afco products.

we ran at the burg and winston this year, but not on any regularity. Money was tight this year, so when we wrecked the car it took a month to get the Jet mod together. Warrensburg would have to be my favorite track by far. Winstons alright, but way too many classes.

I changed the lengths of my 2 link(made them longer) and the pickup points(changed the radius the holes were on)and it has made such a dramatic improvement in the forward bite on heavy tracks that i was taking bite out of the car and it was working very good on dry slick tracks that i never added any lead on the car at all. I ran 51.5% ls, 51% cross, 57% tail and 100lbs of lr bite, i varied these % numbers to loosen it up but i never went far enough to make it as loose as i wanted it to be then the season was over. One more thing i changed the wheelbase(made it longer also).

i measured my links and my lower links are 22" long. i am going to chang the brackets so i can ru the 22" and a shorter one also. i am thinking of shorting the lr to about 16" think that will make a big difference in handling. it is really loose now off the corner and i want it very tight.
