First things first, your car is now 17 years old. Everything is old and worn most likely. If it was me i'd renew some parts On the front Ball joints Shocks and/or Top mounts Track rods Droplinks Anti roll bar bushes Wishbone bushes (can get an anti lift kit for the rears, well worth thr money) Whats the steering rack feel like, non PAS is quite direct so should feel fairly good One the fronts sorted get your tracking or alignment checked, in fact it might be worth having it done first. If you do get somewhere good to do it, local tyre places tend to botch them thru and dont seem to do a good job. The rear theres not that much Panard rod bushes Topmounts Axle mounting bushes (not usually a problem) If these parts are ok the first 3 things i would say feel for money would be. Set of springs, 30-40mm dont worry about looks stock shocks wont like mad low. Anti lift castor kit (front wishbone rear bush) more positive direct steering. Poly bushes for standard front Anti roll bar and drop links. These are the main things that i noticed gave me a better more predictable front end. Coilovers are too much for bumpy roads but my stock SR shock springs were lovely. Then if you haven't already some alloys with 195/50/15's and a good brand on tyre. Toyo tr1's uniroyal rainsport 2's or others depending on budget. After that a rear adjustable panard rod and rear anti roll bar. Panard stops the rear beam side to side movement and they are poly bushed which helps and ARB helps keep the rear flat and reduces roll. And mostly get your tracking done if you fiddle with shocks or steering items. Woo morning essay, hope that helps haha
