Purely for cosmetic reasons or are you planning to track that luxury liner? It looks great, but if you track infrequently our cars' brakes are sufficient as long as you upgrade the brake line, pads, and fluid. Cheaper alternative to entirely new kits. Brake fade usually happens when your stock lines expand, losing pressure. Getting reinforced lines is the most cost effective unless you track your car often.
IMO, you need new wheels to show off that badboy.
