+2 on Eibach, if you want a compliant ride.

Cut springs are no friend to your kidneys. Cornering is second to none for the price.

Vogtland springs are a good drop, and reports suggest they're marginally firmer than the Eibach springs. They're also a bit cheaper. Check ebay.

One final thing: did you trim your bumpstops? If you didn't... ding ding ding ding!!!!
