Installed the TRD springs yesterday and put on the new wheels. So far I'm loving them. Body roll is minimal compared to stock and ride comfort is almost the exact same, haven't noticed any difference there, so definitely not uncomfortable. If you can live with stock, then you can live with this. Went from a 4 finger gap to a 2 finger gap, which is close to an inch drop (sooo scientific lol). Highly recommend these springs.
Also, if you are considering these or the Eibach Prokit, pick whichever one is the cheapest for you. For me, TRD was cheaper, even after import fees into Canada. About $50-$60 cheaper than the Prokit even if I got the Prokit locally. The reason I say pick the cheaper one is because they are the same kit. The TRD springs are just powdercoated (or painted?) and rebranded Prokits. The new bumpstops even have Eibach branding one them.
