If you are not concerned with the ride, I would suggest BC or ISC coilovers. I use spring rates of 8k front, 6k rear with good success. A lot of people will suggest Speedtech coils but I wouldn't buy a set that had no adjustability since I use them to dial in a lot of oversteer during events versus my street settings.
If you go with springs/struts, I'd suggest RCE springs, Tokico D-spec sruts, and PDE or Com C camber plates.
With all that said, what tires are you running? That will make just as much or more difference as new struts.
