I have been impressed with the Sport springs. I had not intended to lower as much as these spring did but have seen no lessening in performance. I'm sure that on a race set up the geometry difference could be noticed but I've not seen an issue. The slight progression in the spring absorbs smaller bumps while not being soft. The spring gave a nice look with reduced roll and dive under sporty driving (or any situation in actuality due to how soft the factory set up is.) The lowering does not scrape from my experience, which includes some steep driveways, except for my mud flaps on tall and narrow speed bumps (which are hard plastic factory additions.)
They give sport look and feel without the fear of scraping on driveway exits or speed bumps. Compared to the factory springs the difference is night and day. Do note that I have Koni Sport Yellow shocks with pair with these to control them well and give an overall great OEM+ setup.
