You absolutely and positively *DO NOT* want to run H&R Race Springs (or any Race Springs for that matter) with KONI FSD Shocks. The FSDs are not valved for an aggressively rated spring and have only been approved for use by KONI to run with mildly rated springs like the Pro-Kit Springs from Eibach. You can probably get away with using something like an H&R OE Sport (and *maybe* H&R Sport) with the FSDs, but you definitely do not want to do it with Race Springs. If you decide to, not only is it not going to ride as good, but if you do run them with H&R Race Springs and decide to warranty them should you have to (with is probably inevitable with that combo - especially with aggressive driving), KONI is not going to honor the warranty (if indeed you tell them what springs you're using with them). If you're dead set on running FSDs - then use Eibach Pro-Kit Springs. If you're dead set on running H&R Race Springs, then run them with KONI or Bilstein Sport Shocks. We're a direct Warehouse Distributor for KONI, Eibach, and H&R, and can give you some one-one-one consultation on your suspension and what might work best for you based on your driving, if you need it some help. Feel free to PM us with any questions.
