I know CLA's are almost identical to GLA but wondering if the H&R springs I currently have on my CLA will work on the GLA once I transition over to the model in a year. I will be purchasing a GLA next year and since I will be taking off the add ons I have on CLA over to the GLA, wondering if the H&R will work on it. I may be buying the 4matic one though so wanted to make sure. My current CLA isn't 4matic though. Also, if I do decide on not getting the 4matic on the GLA, will it still fit? Any info will be greatly appreciated. Thanks!
