Look to see what the recommended factory spec settings and hight are. Go drive on roads you like to spend time on.
Set the settings as soft as they can go. Drive the same roads. From there start to adjust the stiffness till the car is acting as you prefer. They are single adjustable so you don't...
Yes that's seems accurate as far as pricing goes.
Don't go for the cheapest price go for the best quality. Especially if you're going through insurance.
I've had mine on for 9 months and no issues whatsoever. -4 is my sweet spot. Only downside is that the car tracks the crown of the road and it's a bit unnerving at speed over 65mph.
Don't worry if you get CEL just hit up Jester04. He will get you a tune and in the process you will end up with a new turbo, fuel system and a bunch of other expensive parts lmfao ?

Pretty much all companies who make safety equipment for motorsports have tow straps. As to how to mount them is almost the same as tow hooks. Might need a bit of diy engineering though.
Few hundred for springs and call it a day. You can get them from here no need to get from Japan. Why spend thousands on parts that you don't really understand.
