So i am about to install the eibach pro-kit spring on my 06 coupe and I remember alot of aftermarket springs I've installed in the past suggested you cut the factory bump stop in half due to a shorter spring. The eibach pro-kit the instructions don't mention anything about cutting these. Can anyone that have these installed let me know if cutting these are needed. Thanks

 

Thats a valid question, No because these (Pro Kit) springs are progressive, there shouldn't be any need to cut the bump stops.

 

Awsome, thanks for the info

 

i cut the front bump stop by 1" .

you can leave the rear alone.

The front bumpstop is inside the boot. you have to pry it out first.
