Question Correcting the negative effects of lowering

I've been gone for over a month and have nothing better to do then read information on cars and such. I came across this a few days ago and haven't been able to find any good information on it. But here it is:

On most Subaru cars when they are lowered more then 1" they lose alot of there contact patch during cornering due to body roll. This wouldn't usually happen if the car was at it's stock hight. My question is how do you correct this problem? Would you get a stiffer suspension to reduce body roll, ajust the camber, shorten the control arms. I've looked everywhere and haven't found a solid answer. If anyone know could you share the info.

I appreciate it. I would have been good to have something like that before I came out here. I read an entire CCNA book. It's like 750 pages of stereo instructions.

That is only the fact if you buy something like s.tech's that have a softer than stock spring rate. Stiffer springs shouldn't reduce your contact patch. If the drop reduces your contact patch then a simple and cheaper way to increase the contact patch is by running wider wheels with wider tires. If the contact patch is only less in corners then kick your camber out so that in coners more of your tire is lying down to the ground.
