where can i buy new bump stops? i got some koni's they didnt come with any. my old ones are garbage.

 

From GC (same as used in their extended upper mounts)

If you want to tune your bumpstop behavior:

wow i thought they were like 5 bucks ill wait to get good ones when i get my GC and a can do a little research on what i need and all. thanks

 

There is always junkyard pulls, if you just want stock. Should save quite a bit that way.

You might also consider posting in the classified section, as many people (myself included) are using GC extended upper mounts, and have stock bumpstops just sitting on a shelf somewhere. Mine are only kept in case I decide to put the stock suspension back on, but many won't need to keep them and would probably be willing to part with them for a little over the cost of shipping.

 

thanks! hey another question..say i go with the ones on GC site... whats the difference between stiff liner and soft progressive?

 

I received the "soft progressive" stops with my GC upper mounts. They are much softer than stock, but even compressing by hand you can feel the progressive nature of them.

I imagine that the "stiff linear" have more of a linear curve to the compression resistance (spring rate),and start out stiffer. How stiff? Without a nice graph, it would be a wild guess.

Notice how the other link I posted (with tons of different bumpstops) has graphs showing the rate change under compression.

Progressive (and they look like the GC "soft progressive" visually):


Linear (or more so at least):


Of course, at this point, we're stepping right outside of my knowledge realm.

If you don't know how to tune with the bumpstops, then you can take the approach I do. Consider the bumpstop to be nothing more than a "last ditch safety for the shock", try to avoid much contact with it, and use a progressive stop to minimize the change in car behavior when contact does happen.

 

ok sweet thanks alot..yeah i can see how this gets confusing. i think i will go with the soft progressive ones as well. thanks!
