i have a 91 corolla that i am goin to upgrade the suspension on. it is the seemly unpopular sedan though.

i plan to see some track action in it and part time drivin as well, so i have some questions
first: i found some coilovers by jic magic (good brand?) that say will fit for $1,805 at best. or should i upgrade to AM shocks and lowering springs? if i do that will i have to worry about improper camber angle and need to get a camber plate or adjustment bolts to set to proper camber?
second: what are available as far as chassi support? i have found strut bars easly of coarse but i dont know what size i need for my car. do i need the 35mm or 40mm? also are there any sway bars that will fit in the front and rear?
third: i was wondering if there are any bushing kits that i can get to stiffin things up a bit. i have found kits for the gts but i dont know if suspension stuff crosses over between the two cars.
sorry for so many questions i just want to get some things straightened out before i start spendin. thanks
