I am currently running Neuspeed Race springs and Tokico Illumina struts. The struts are now blown and the ride is horrible. This car is my daily driver/weekend racecar so I want a smooth ride and yet good handling capabilities.

Here's what I am looking at so far:

(1) Bilstein BTS kit (4 Bilstein springs, 4 Bilstein shocks) - $630 for the set.
(2) Koni Yellows with...
> Intrax springs?
> Sprint springs?
> Ground Control C/Os?
> Skunk2 C/Os?
(3) I dont know if anyone has heard anything about them, but Arospeed (yeah I know, crap) is selling threaded shock body coilovers now. I'm sure they're made by someone else so I wonder if they're any good? If anyone has heard about them, please tell me your thoughts.

Thanks!
