Eibach installation instructions for my springs say to cut the bumpstops 30mm in the front and 26 mm in the back. That seems like an awful lot. I dont know how thick the bumpstops are but 30mm is like an inch and a quarter.

 

The bumpstops are pretty thick. Once you take the suspension apart you'll see.

 

that's pretty normal. i cut about the same with h&rs, and einbach sit even lower. you will need that extra inch of travel with the drop.

 

you'll have to cut the bump stops or the struts/shocks will bottom out and not get the full suspension travel they need. plus it'll ride like crap if you dont and you hit them. you'll know when you do. i think just about every manufacturer instructs you to do so. i've done TEIN, Eibach, and a couple other brands i cant think of and all suggested this. no fear. you'll see that the stock bump stop is usually 3"+ so there will be plenty left over.

 

Does anyone know how much one would have to cut of the bumpstops with Maxspeed springs installed?
