If your autotesting youll want the coilovers. I always push the rear arb first but in your case youll want coilovers and you wont need damn all else. Ive just noticed youe in a ep80. You dont have a front arb so get that from a gt glanza or ep91 na. The na would be better because there droplinks are adjustable and much much much cheaper than the turbo types Your panhard rod should be the early round type, so you can cut it, pack it with a stiff round bar and reweld it along its full length.
