Bumpstops

[erwinlg]

I need some help and education on bumpstops. Basically, what is the purpose of them. I had always thought they were to stop your axle or tires from hitting the bottom-side of your car when you drive over a major bump or pothole. But then someone else told me they are there to prevent your shocks or struts from compressing all the way which could damage them. The reason I'm asking is I just recently installed an Eibach Pro-kit on my PT (02LE) but I didn't trim the bumpstops on the front or rear suspension.....Thanks, Erwin.

i trimmed my bumpstops on the rear when my brother installed eibach springs.

They are to prevent your shocks/struts from compressing all the way. I trimed my front and rear bumpstops 2" when I lowered my PT 2".

Thanks for the info everyone. But now I have another (stupid) question. The bumpstops for the front, are those the ones on the strut shaft that the Chilton manual refers to or are they located somewhere on the front frame???.....Oops, here's another stupid question, when trimming the rear bumpstop (which are shaped like the michelin man, right???) do you trim off the bottom or try removing them off the frame and trimming the top???.....Thanks again for the help, Erwin.

Erwin, yes they are on the strut shaft, they are easy to cut with a razor knife of something similar. For the rear I left my bumpstops on the vehicle and just cut 2" off the bottom, like I said, they are easy to cut.

Thanks Again.....It looks like it's back to the tire shop for me, so they can take the strut/springs off again and cut the bumpstop for me (I'll do the rear myself). Unless someone out there can convince me that Eibachs don't need the bumpstops trimmed.....Erwin

you have to trim the bumpstops with the eibachs, it makes the car ride better. thats just from personal experience

Well, I lowered rear only about 1.5 - 2" (I forget which) and didn't trim the bumstops - I figured I could always do it later, haven't found a need to.[:I]

Ive bottomed out ONCE and I never trimmed mine...and sometimes I drive like a fool (I should really be driving a rally car ).

I also have Eibach springs installed and when I hit a small pot hole it like something is coming into the car. I will check the bump stops.
