What good is all of this power if you can not control it? The suspension is equally as important as the motor, and deserves a healthy injection of modernarity.

For starters, I chose to go with these HyperCo springs. They will lower my car no more than 2 inches, giving me an agressive stance without worry of bottoming out. These are reknowned to be the best springs for the B13 sentra. Buy them if you can find them.
I will be pairing these springs to a fellow forum member's custom made shocks using shortened Konis. Expensive, but from what I gather, well worth it!
I plan to upgrade to NX2000 brakes with stainless steel lines and to add a Active Tuning Rear Strut Tower Brace in the near future. After winter passes, I will be rolling on 15'' lightweight kosei k1 wheels with Fuzion ZRi tires.
