I bought these sport springs along with Bilstein sport dampers for my Mazda MX-5. The old dampers were worn out which gave me an excuse for the upgrade. After changing out the springs / dampers I can really tell a difference. Right height lowered ~1" giving a little sportier look without being too low. Handling is also GREAT; the car stays totally planted in tight turns. Definitely one of the best upgrades I've done to date.
Best springs on the market
ive had Eibachs before, and I was never disappointed with them. so I went with them again, and once again, they have come out as a great investment. handling on the car improved, along with the feel of the car. the springs make the car slightly tighter on bumps but still a very comfortable ride.
