Couple questions before i install my sportlines saturday...1st and most important...ive never installed springs on a cobalt and hear something about bump stop cutting? is this just on the back? does it have to be done? and if so, how much do i cut off? also, even if my old struts get worn, they wont ever physically break will they? and last but not least...who all commutes with these springs? i live in a different city than my family and drive about an hour to my home town and back every weekend. thanks guys.

 

bout to install these later this week, so im subscribing so i'll know when you get an answer i to am curious about the bumpstops and how much to cut off the front and the rear, the paper that came with the springs for me said 30mm front 13mm rear, but i want ot know for sure.

 

Cut the rear bumpstops in half. I didn't touch the front. I cut them where the bumpstop starts to "round over". You'll see what I mean when you pull them off. I commute with my car, and its been 9 months since I've put the springs on. I do plan on getting the Koni's in the winter though.

i looked on some other threads... they all say 30mm front 13mm rear.

 

Eibach includes a measurement for how much to cut with the instructions, its about 22mm front and 15mm rear I think, I could be wrong. Do cut them, they are a foam material, use a hack saw, or a serrated knive, razor blade, whatever works.

Struts can't "break" from springs, they will just wear out and not do anything, making the ride bouncy.

The Sportlines to me ride much like the factory springs, not harsh at all. Thats why you pay a little more for Eibachs than some of the others out there, they work well.

 

i just checked my paper 30mm front 13mm rear.

 

subscribed for when mine come in =)

 

Just follow the how-to's and you can't go wrong.

 

damn i forgot all about the how-to on this

 

thanks for all the help guys. i had every intention of just following the how-tos but there seem to be so many horror stories on here about install. maybe just rookie mistakes i guess? i hope they ride nice lol i winter drive my car and highway drive every weekend. maybe koni yellows will go in when im done school in may
