When I was installing my Tein S-Techs a few years ago, the bumps had to be cut in half on either the front or the rear...can't remember, maybe both. I'm putting all my stock parts back on so I can trade in my car. Do I need to get new bumpers or can I use the cut ones just fine?

 

You'll be fine the cut bump stops just increase the amount of travel the shock gets while their paired with lowering springs.

 

you should be ok, the bump stops help your suspension components from bottoming out.

 

I doubt they'll actually check that
