Bump Stop [Merged 7-7] stops

91_talon_at · 03-28-2003, 04:18 PM

i'm goin to install my springs n shocks soon...and i was wonderin why or if you even have to cut the bump stop. any info is apprecitated.

b/c your losing an inch or 2 of shock travel by lowering it (depending on the springs you get) they recommend cutting 1/2 to 3/4 inch to get some of the lost shock travel back.

This is very true, NOT all springs require you to cut the bump stops. For example my neuspeed sport spring, I had to re-install a new bump stop in there because i cut off too much and the car would kiss the tire sometimes. I then found out that neuspeed says not to trim the back bumpstop when using their product.

i have eibach sportlines 1.75 or 1.8 drop on these. and i'll be runnin on some AGX's. You guys think i'd have to cut the bump stop?

ECLIPSE4x4 · 03-29-2003, 03:39 PM

Like was said above... it depends on what the manufacturer states....

If you don't trim the bumpstop, you will end upo banging your upper perch onto your shock body, destroying the shock.

You only need to trim the bumpstop if your car is constantly sitting on them. Sitting on the bumpstop only hurts suspension performance, increases cabin noise, and makes the car unsafe.

With sportlines i think you are supposed to cut the bump stop 1/2 way. I had to cut mine 1/3 or so with the pro-kit. My springs came with a sheet that shows how much to cut it.

Blk95gs · 04-07-2003, 10:55 AM

you mind sharing that sheet with me? my car is in the process of having tokico blues and eibach pro kits installed on it.

daltah · 04-07-2003, 11:07 AM

Should you cut the fat end or the thin end?Also i have coilovers on my car and have them all the way up but it still sits between 1-1 1/2 inches lower than stock so how much should i cut off?

Hi, my front supension bump stops are all teared up and less than quarter inch is left on the shocks(my car is lowered), i called satan and they have to order them i dont have time to wait. I also checked scrapyard and the bump stops there are all the same condition as mine

.No auto parts cary them to,My question is can i make them, im thinking of buying maybe some rubber or prothane bushing drilling the middle hole bigger and using them as bumps stops. Is this a good idea or this will mess up my suspension because they are harder (rubber/prothane)than foam stock bump stops. what do u guy's think or u have better i deas of making the bump stops. Im open to any suggestions.thank you.

I would say just get OEM..You can TRY your way BUT it may be harsh if you bottom out since OEM ones are more "mushier".

Does anyone have a picture or know where I can get a picture that will show me where to cut the bump stop? I just got the Tokico Illumina shocks and spings 1.75 drop. Thanks.

Module Unknown · 06-10-2003, 09:59 PM

Here are some pics. This is what I went by.

You'll find some pics of cut bumpstops in there.

It all depends on what the manufacturer of the SPRINGS tells you. I made the mistake of cutting mine and come to find out with my springs there is no need, or rather the manufacturer suggests not to trim them.

All I am saying is make sure you need to cut them before you do.

snipe99999 · 06-11-2003, 07:05 AM

Thanks for the help. I got the Illumina shocks and springs yesterday. I did not think that there would be any instructions but there were. They recommend cutting them in half. They even included a diagram. I just wanted to be sure before I installed them. Thanks again.

91silvergsx · 06-30-2003, 07:48 PM

okay i have a 91 gsx i have rage 5.0 wheels and nitto tires. i just put aem brake converstion and a rnr 2.5 turbo back exhaust. i am putting the suspension together. i think i am getting 4 gr2 shocks and ebiach springs. this will lower my car about a inch all around. do i need to cut the bump stops to compensate. please guys tell what you think. i am not building a race care just something that is really fun to drive.

ECLIPSE4x4 · 07-02-2003, 09:44 AM

When you get the springs, there will be a note from the manufacture in there telling you how much to cut if any. It all depends on the spring. No two are alike.

Wikkedson · 07-02-2003, 10:18 AM

What if you leave them out?

Then you could damage the shock if the spring compresses too much.

91silvergsx · 07-02-2003, 11:10 AM

thanks for the help when i first got my car the guy i bought it from said he just put shocks in the front and then he handed me a box of parts the bump stops were in there. i didn't put them back in and about 3 months later the shocks were history.

Velo_TalonTSI · 05-23-2004, 02:31 PM

Does anyone know how much I trim off of the front bump stops, I've lost my directions for my springs. They are for a 1991 AWD. Need help. Thanks.

HokieDSM · 05-23-2004, 11:33 PM

Not to jack the thread, but I'd also be interested in knowing this, if anyone has the info for Pro Kit springs as well, that'd be wonderful.

ohio98eclipse · 05-24-2004, 07:55 AM

I'm sure this has been asked before but my 98 gst is lowered 1.25 inches with tnaumi springs or however there spelled. I just got my kyb adjustibles today so when im installin my new shocks id figure id cut the bump stops. How much do i cut? why do i cut? do i need to cut with only a 1.25 inch drop i cant seem to find a sure fire answer on this one. Any wiseman help would be appreciated
