Got my whiteline control springs installed today and I'm extremely happy with it. First impressions were that I thought that it was only going to lower the car by 30mm, but it looks like it's lowered it even further. The fronts are lower than the rears. Handling has improved so much and has significantly minimised that irritating body roll when turning. Also when changing lanes, I get more responsive steering rather than that floating feeling.
At long last, I'm going to start enjoy driving this car around the bends.
