Just got my 08 lancer last week, came with some rrm parts. They are the rrm intake, axle back exhaust with the upper and rear upper strut bar. Now I am planning to get the header, pulley and lowering spring. My question is will the spring and pulley be too hard on a daily driver? This is my only car for now and I traded in my old car for this one. I asked this because, my old car have lower spring too, but in the end I have to replace due to a blown shcok, the strut is even a made by kyb, installed together with the spring. Will the spring be too hard with our stock shock. How about the pulley? I know header will def not cause a problem

 

Pulley will be fine. Chances are you won't even feel it.

Springs should be OK. Most of the folks that have them say it's a gentle spring, close to the stock rates.
