h&r is a big drop, I had them on
THIS car that I sold if you want to check how it looks. They were on koni yellow's, and the ride was pretty shitty and harsh too...felt every bump being transferred from the road to the chassis, and I didn't like them at all....they came with the roller, and sold with the car!!
I would highly recommend another option, such as a moderate drop from the eibach's, which can be seen
HERE on my other car that had Koni yellow's as well. (that's a link to the FS post that I purchased the car from)
MUCH better ride quality, reasonable drop, etc.
Good luck!!
