If you want to go really really low, you need coilovers.

You can get Kings Ultra low springs...same part numbers, but SSL instead of SL. BUT, dont expect your shocks to last very long. If you wanna do this, you'll need a set of quality shocks i.e. Koni, but by the time you spend that money, you might as well buy a set of coilovers.

The ride might be good with SLs, but it deteriorates dramatically if you go too much lower than that. Adz had Kings Ultra Lows and Koni's in his MY01, and it handled and rode very very nicely...but as I said, it has Koni's, and this helped a lot.

Coilovers will be very uncomfortable also, unless you spend the dollars and get quality items.
