Well, for the month of may, I'd say there were some pretty good upgrades released. Upper and Lower Intercooler pipes for $300, some ecu stuff, several exhausts, Eibach springs, etc. I'd say that the best upgrade for the month, IMO were the Eibach springs. Despite the availibility of some $2000+ coilovers, the springs are still a great upgrade. Eventually, the dampers will be out and there is already the anti-roll-kit. I'm still undecided about which way I'm gonna go w/ the suspension, but thats the great thing about the Eibachs, they're inexpensive, easy to get, are aesthetically pleasing, and improve the handling greatly. If I decide to go a different route later, I'm not out much, but meanwhile I will really enjoy the change.
Eibach gets my vote.
