I have a `90 2wd sapphire cosworth in need of handling mods. I have AVO coilovers, ESCORT COS 26mm Rear ARB on the way and adjustable bottom arms for the front. What else can I do to help the front end turn in and grip and get the whole car to handle better, more predictably etc? Solid top mounts, front and rear strut braces, roll cage, seam welding? what will make the most difference for the money
