Need best springs to drop the rear 2"!!

[RUQWKNF27]

I have finally got tired of the gap on the rear of the car an since I am moving to 20" wheels I need to close this gap anyway. So what have you guys seen that works good? I have seen spring sets "Eibach Pro Kit" an such but I just need 2) for the rear.

Suspension Techniques also makes a drop spring kit (all 4) Summit ad here,
REGAL, 1987, 3.8L/231, BUICK, Chassis & Suspension - summitracing.com
And a few extras to look at.
I have STs, and 2" spindles...still not on the car though.

Are you going to put 20" wheels on this car? I like the way they say 1-2". I know they cannot know for sure but guess best to hope for would be 1.5"!!!
