Well, you have a 3" BL and you can either get the Camburg 6.0 that starts at $1950 which is a 3.5" spindle lift (Crank the torsion bars for the extra 2.5" for 6" total) with a new upper control arm and you can also get it with dual Bilstein shocks. www.camburg.com
You can also get the RCD lift kit that replaces the Torsion bars with a coilover and runs about $2400. www.racecardynamics.com
Then you can get a spindle (4-5 different brands) which will run you about $350-$400 and then you'll have to do something for the rear.
When/if I do a spindle lift, I'd be replacing the T-bars for "F" bars from a FX4 Level2 and some Bilstien HD shocks and 4" lift shocks in the rear with some Skyjacker 6" leaf springs and removing the stock rear block (equals 4" of lift).
