I have a '10 and the person I purchased the car from installed Eibach Sportline springs on stock dampeners and I believe that the passenger side dampener is blown out cause when going over some bumps it sounds pretty bad, It makes a loud thump. Well I've been looking and rather than getting some performance dampeners or going with the Omni Kit and older style dampeners I have been looking at some coilovers since some performance dampeners can be expensive, I have narrowed it down to 3 choices: DGR, KSport, or H&R. I know alot of people are using the H&R's and Ive seen at least one person on here with the DGR's but the KSport's say 06-07 and Im wondering if they are still good to use on the 08+ cars? Im kinda leaning towards the KSports since im mainly just going to be doing street driving and they are alittle bit cheaper. Anyway which ones would most of you choose? And what are some pros and cons of the different brands?

H&R. pass on the other two

Yup

Otherwise you MIGHT just buy 'em later, when you aren't happy with the "cheap" ones....

It's the pricier way to learn....

While the struts could be damaged check the front sway bar endlink as well. They can make similar noises when they get loose as well.

and dont forget to check the strut baring on top of the spring.
