I mistakenly ordered 2x front 5100 sets and he's got my spare set there in teh shop, might make you a deal on them if you ask specifically. What I will say if that you should def go with the ToyTec springs. I reused the stock springs on the front on my 3rd gen first and they sagged within a few months. The rear OME mid rates and 5100's rode great with stock weight.
Glad you touched base with Pete. I seriously cant say enough good things about his work ethic and his commitment to making this hobby/pass-time/whatever great from not only a business point of view but also from a interpersonal point of view. I've seen him do a good once over (free of charge) on new vehicle purchases for customers vehicles several times, heard him make appts for guys to bring used trucks they might buy to the shop for a quick "second set of eyes" check, etc, etc. For a guy as busy as he is (VERY!!!), him taking time make sure his customers are happy no matter what says a lot and because of that he has earned my business for a long, long time.
