Hey everyone !! I whant to know if others ever had this issue with there lowered tsx .. I have a 2010 tsx v6 68000 km still have Acura plus warranty until 2017 I just installed a set of Tein street advance coilovers last week with 2008-2011 accord 19 inch hfp wheels 245/40/19 I'm lowered between 1.5 to 1.8 inches flush to the wheel wells I gotta say the teins ride really smooth couldn't be happier ... I just recently started to notice this very slight vibration when accelerating lightly between 40 and 60 kph I think it's coming from the passenger side I'm not 100% sure .. I just got the car aligned and all 4 wheels balanced and the vibration is still there but wasn't before the install when everything was stock .. I just hope I'm not messing up the car .. Let me know what you guys think !!! Thanks

 

That usually points to an axle issue. If that is the issue...Acura won't warranty a worn or vibrating axle on a lowered car.

Could also be worn engine/trans mounts/subframe mounts. Which...again...probably won't be warrantied due to the suspension.

If you do take it in, I would first return the car to stock.
