Default Ground Control...... ?

so I installed my kit went and drove it around and there is still a little thump in the passenger rear, even after I added a washer. The Drivers left, no matter how big the hole I hit is, doesnt even make a sound.

Any Ideas?

I would just add more washers (as many as you can and still be able to tighten the top shock nut properly).

Yes, I think that is where you are supposed to add them. Last time I had some suspension work done I had my local shop add the washers for me. I'm almost sure they just added them to the top, but they didn't add enough because the clunk went down some, but not completely.

just grease the top and bottom of the shock a little.... then you should be fine. Overall it's a pretty good kit for the price. Oh and dont forget to put washers in too

No, not yet. That was only a couple of weeks ago. Next time I happen to have my rear seat out (which probably won't be for a long time) I'll just add more of the washers myself.

It's metal on metal, it's gonna clunk. I found that a thin neoprene washer between the other washers on the back, especially on the top, helped quiet it down.

The fronts on mine don't clunk but when there is extreme angles such as pulling into a steep driveway there's a nasty metal rub click thunk type noise

The bottom line is this: if you're buying a gc kit hoping that it will be quiet as stock, you are going to be disappointed. It won't be, period. There's thick rubber at the top and bottom of the stock springs for a reason.

The kit is a clunky but it makes the car look great.

I'm hoping that when I put on my qa1s that the rear clunk subsides. I may get some helper springs for the front to minimize the unload on driveways etc..
