'99 coils are about 1" taller than the 96-98's while your 01-02's are about 1" shorter than the 96-98's. I would bet the 99 coils would give you closer to 2" of lift.
I just put a DayStar 2.5" suspenion lift on my '97 SR5. I love it. It is just what I was looking for. I ordered it from www.performanceproducts.com. Check it out, I think it will fit your needs.
