A few questions: 1) how much of a drop from stock 2015 Prius height and how’s the ride? 2) will the car be “alignable” with these springs without a need for camber plates etc.? 3) ease of installation if I’m looking to do it myself? 4) shipping price to 33414? Thanks!
About 1.3"/1.4" front/rear. Here's some photos of the springs installed on my car, Right, no camber plates required. Straight swap. Link to manual here, https://www.toyotapartsdeal.com/resources/installation/tpd/my10%20prius%20lowering%20springs%20issd.pdf I had a shop install and remove. According to my friend at the shop, he recommends setting aside a couple days to do the job if it's your first time (check manual above). You'll need to borrow/buy a spring compressor etc. Ask $200. I'd split the cost ($50 to FL) of shipping to you.
After back-to-back days driving my Prius on TRD versus stock springs yesterday, I'd say the ride is a nice balance between daily driving and handling. Road noise and transfer of bumps didn't change much at all (if any) with the TRD springs. The stock springs feel sort of pillowy and not as responsive on turns. On-ramps and off-ramps became fun with the TRDs. You do need to be a bit more careful pulling into driveways and speed bumps.
