We have a 02 Harris running a 4bar/swingarm Zlink and just switch from a long panhard bar to a j-bar. The car seems very loose in the middle to off portion of the corner. I think that we need more rear % (58% now) but I don't know of any way to get it without adding lead, and the car is already to **** heavy. Anyone have good ideas??

rear springs lr 250 rr 275
left side 52%
rear 58%
30 pound lf heavy
60 of left rear bite

13, Your rear % it's good. I have found that more than 59 makes the car loose in the center. Your rear springs seem very heavy. I'm at 225 Lr, 200Rr. Where are your rear springs located? Are they clamped on a birdcage or free moving? We can get you going give me some info. E-mail me at tomeiklor@htva.net. Idealt with simular problems now I've got mine going.

RR spring sounds to heavy, try 225 if not 200. The stiffer RR will de-wedge the car mid & off. Rear % is OK.

You definitely need to swap your rear springs around. You might even drop them by 25lbs, not sure, depends on track dimensions.

If you'll take some angle out of your swingarms and get rid of some dynamic rollsteer you'll tighten your car up but the trade off is loss of forward bite.
