I'm on a 2.5" Dobinsons lift, SSO/Moog rear conversion with no spacers, and SPC UCA.
My rears are the same as yours:
GS59-705B + C59-505

Wheels: SCS Ray 10's 17x8.5 -10mm Matte Gunmetal
Tires: LT285-70-17 C load
Lift: Dobinson's 2.5" medium springs with comfort valved rear shocks.
Other Mods: SPC UCA's set to position B.

That's really good. I had a heavy foot this past weekend so patience wasn't my thing. I averaged about 17-17.5 all stock, loaded with wife + 2 kids, luggages and all. I could've got another 1-2 if I wasn't going so fast, passing everyone up.
I drove my 05 from Sac to LA on Sunday morning. No problems over the grapevine. I was cruising 70-75 MPH for most of the trip.
Monday afternoon drove from LA back to Sac going roughly 80 MPH on I5. No issues.
Speed and power is subjective. Everyone has a different opinion.
