A buddy of mine is a mechanic at a performance BMW shop and has his own
I was a little worried about the springs making the ride too stiff and bumpy but was pleasantly surprised when I got the car back and it rode almost identical to stock. The lowered height is just about perfect as it cinches the tires up into the previous gap of the wheel wells and doesn’t sit too low to make it annoying when pulling into driveways, bumps, etc. The few places that you will notice the springs is when you go over those Mountainous speed bumps that some parking lots have. If you do anything but a half mile per hour crawl, you will feel the springs bottom out. The other place that you will notice a difference from stock is when parking the car in a parking lot and pulling up to the curb. You need to be careful not to pull up over the curb as most will scrape your front splitter. As for the handles, you can definitely tell the difference in the high speed turns.
This is one of those mods that please both aesthetically and performance wise and for the low cost, it is hard to beat the huge improvements it makes to the car
