Springs!
You will spend equal too if not more on OEM when for less or equal you can have H&R springs. They might bring the car 1/4 inch down if that, but nothing noticeable. They also are progressive so ride like stock but improve handling 1000000%. Mercedes uses H&R for all their race cars and H&R are provided for most Ford vehicles. Thank me later. I put them on my 93 Cobra and my ride height had no change, just any corner, any speed. You can expect between 220-250 for the set. Do it yourself or ask about people on here who know SC's. Mechanics know nothing about these cars. Your love and a Haynes will take you further than most shops.
