I was in the same situation approx 6 months ago....
To sum up i installed BC Coilovers and i have never looked backed.
I use my car as a daily drive and travel approx 100km each day round trip to work and home.
Pros:
-Exact ride height to the mm and takes approx 1h max to change your cars height depending on what equipment you have (Very helpfull if you have wide rims/tyres)
-Dampening Settings are a big + as it take 2 mins to change your car from soft to hard, and if you have your car on the softest setting, the car feels close to stock, I personally have it 3/4 hard cuz i love the harsher ride = more of a sports car & +++++ on handling
cons:
- there are some roads in sydney that you will hate but to me the pros easily outweigh the cons
I cant really say much about the springs option, however if you do install lower king springs you will get a harsher ride then stock and your limited to 2 ride heights, Low or extra low. Also from memory I was quoted about $600 to supply and install new king springs only, im not too sure about the struts…….
Hope that helps
THIS. Exactly right !
