What you have right now is an excellent recipe for a good-handling, stock-level car. You will probably be happy with the results, and the car will be responsive. However, this will probably lead to a desire for further upgrades and even more responsive handling. You can achieve this with the stock-style suspension, but it requires finesse and proper parts selection. You will eventually try larger torsion bars, heavier rear leaf springs, and progressively fatter anti-sway bars. Wider, stickier tires will find their way onto your car, and you will wind up reinforcing the seat mounts, and adding wider, more restrictive safety belts to hold you in. Enjoy the process; play with the car as it will be after your modifications, and decide then where you want to change things next.
