Bump Stop Question
Friday, May 11, 2007 6:44 PM
It might be a stupid question, but will driving with no bump stops hurt my car? Im riding B&G springs on dspecs, the rear rides a little rough , could the bump stops be the reason?

the bumpstops having nothing to do with it riding rough, they just keep the car from bottoming out too far, did you cut them on the install? not sure with those springs if you have to or not, instructions would have said

Exactly as their name implies, they are the last resort for stopping suspension travel before the strut reaches it's mechanical limit and clashes metal-on-metal. You would surely have noticed already if this was happening -- but just because it hasn't yet doesn't mean the next speedbump won't make it happen.

My recommendation is to stick with trimming the bumpstops rather than doing away with them. Tokico recommended I trim my fronts by 0.5" and rears by 1" for Sportlines, and the results seem good.

ive been wondering this myself as i seriously dont get how the car could bottom out THAT far... i mean the spring would have to be SEVERLY crushed to reach the bump stop... but i did as recommended and chopped them down and re-installed.

meh, screw all these frickn suspension components, if i could do it all over again i would buy the tein FULL assembled and ready to bolt on the car setup. its been a nightmare and a half trying to get things right. nobody on here is willing to share pictures of how all the shiit goes together in the front's nor explain how they go together (the rubber crushy deals and the rings and all that BS), so its been rough. lol, oh well...

(i had crap coilovers installed last year and all that stuff was removed so i had no idea of how and where it went)

if you dont know how to do suspension mods why are you doing them then? its your own fault. the spring can reach the bump stop if you hit a pot hole, it has alot to do with your speed, momentum, and your ride height. it goes together the exact way you took it apart, these are replacements for factory parts.....it doesnt take a brain surgeon to see how something goes together when you take it apart.

and Jay Blake, if your suspension if hard in the back, adjust it, you do know dspecs are adjustable right? try 6 turns from full hard in the rear. mine rides great.

oh god i wish i would had the option OF being able to have taken them apart, but unfortunaly... i didnt. tuffy installed my coilovers and threw and the unused shiit in a box (which was basically everything)

ohhh and koni yellows arent even close to "replacement factory parts" its a TAD more complicated than that and me being with pretty much zero suspension (on a j-body) experience, its been a lil hard to figure stuff out, koni's instructions are pretty much worthless and eibach's is pretty much the same way-but a little better.

as he said, if you don't know how to do it, why are you doing it then? Either pay someone to do it, get a friend who knows how to do it or get a haynes manual, suspension really isn't something you want to guess at, it isn't like most components, if they break you just roll to a stop on the side of the road, if you @!#$ up something and it goes on the suspension usually it isn't that graceful of a stop

1.) Doing it for the experience and knowledge, as I already had a shop do the previous suspension and they did a crap job. I want it done right. Hence why I spent the $800 for Yellows and Sportlines, bought brand new mounts all the way around.

2.) It's taken me a little over a month to get it mostly figured out, I'm not guessing.

3.) My dad has been a mechanic for 30+ years and has done tons of suspensions, just my cars for FWD experience though.

4.) I have a Haynes manual, it shows 00+ mounts, the pics arent even that clear.

Just because you havn't done something before doesn't mean you shouldn't. I think thats the worst advise you could give somebody. I wanna know about my car works and how it goes together. I would never guess on something as important as suspension, Idk why you even thought I was guessing. At no point did I mention I was guessing.

theres alot of parts that go together for the suspension setup. best bet is to pm cts and ask him. he helped me out alot when i was converting my car back to stock.
