So I've been reading around on this forum for years now but this is my first time posting.

I lowered my 2012 Accord V6 Ex-L Coupe on Tein Street Advance coilovers about 3 weeks ago and have been experiencing some shaking between 20-30mph while on the throttle. It becomes less noticeable, the faster I go.

Everything I've read pointed towards there being an issue with the CV Axles. I had the passenger side changed, followed by the driver side and the problem is still there. (New Axles from Car Quest were used.)

I raised the car a bit to where I now have a 2 finger gap in the front. The shaking is not as bad I think, but its certainly still there.

I'm at a lost as to what the next step is now, as all the threads I've seen on this issue, have ended with no solution.

Any help at all would be greatly appreciated. I've seen many 8th gen coupes lower than I am right now, so I'm sure there's a solution out there somewhere.

Note: Stock 18" wheels and only other mod is Takeda SRI
SPC Camber Kit installed and Alignment is within Spec

Thanks!!

You bought 60 dollar axles from advanced auto is the problem. Do not EVER use aftermarket axles when lowering a car. You need OEM axles. Most parts of the car can use aftermarket stuff except axles

So true, it should be a sticky....

Axles turn at high revolutions per minute. They must be perfectly balanced or you will get vibration. These lower-quality aftermarket axles are made (really, poorly recycled) for "errand boys, sent by grocery clerks to collect a bill." That is a reference to the movie Apocalypse Now.

The cost of Honda axles is higher. Very tempting to go with an aftermarket brand. Don't! On the 7th Gen forums, about 50% of the aftermarket axles vibrate the day they are installed. Another 40% start vibrating within 6 months. About 10% get lucky.

Like drugs or buying a new Chevy- just don't do it.
