Bump Stop Help

[MasterSbilt_Racer]

I am not disagreeing with the other posters, but if you have the rebound and aren't getting too deep into the stop on a rougher track, you can run it and have some benefits.

What i was going to try was putting (keeping) a spring rubber in the 300#, yielding an approx 330 # spring when it's not smooth and slick, and pull that out when conditions warrant. Seems like that would keep it mostly out of the bump until you wanted it.

Am I crazy ?

I haven't had anything specific like that done to the shock. I bought it (them) used as a set. What's special about the valving for a Integra IDA on a bump stop ? Again, keep in mind I'm running to "make the show" .. I'm not trying to light the world on fire yet. Will I even be able to notice any difference in a shock valved for a bump ?

Sure hope that doesn't sound contrary .. just trying to learn something

Not contrary at all...
7up hit on it. In most cases, you need the shock to have a different rebound profile than what works best for a standard spring or even for a dual-stage spring setup. I personally wouldn't waste the time with it unless your shock builder thinks you've got something that will work on the rebound side (high "zero" and usually a sharp nose).
To me, running a bump stop without making the other necessary changes (mostly shock valving) is like running E-85 without changing the carburetor. It may work if the carb wasn't right to begin with but if you don't know that, you're sort of guessing.
I've said this before and I'll say it again...building a good relationship with a good shock builder is the best time and money you will spend in late model racing. It isn't just about shocks. Most of the good ones know a great deal about vehicle dynamics and understand how to communicate with drivers.
Just my 2 cents...

Its my understanding if the shock isn't valved for "Bumps" it'll land too hard and you'll get an instant, "PUSH". Secondly if the shock isnt valved to help keep it seated on the bump it'll lift off and you'll lose your drive. The car needs to land just so on the "Bump" and stay seated there. At least that is how I understand it.

Thanks for the explanation .. that makes a lot of sense.

In everyday terms lol high zero is your bleed and sharp or big nose is heavy rebound for the shocks velocity area the control body movement aka not ruts and bumps those are in the high shaft speeds

Somebody should post a picture of a shock graph before we get this guy totally confused.

I don't confuse very easily

I looked it up .. and thanks for the heads up ! There are a ton of videos on the subject on YouTube.

These shocks have a "Integra by GW" sticker on them. Anybody know anything about "GW" ?

That's Gary Winger, he usually does track support for Integra.

Sounds like he probably knows what he's doing, and that I can't afford him

[jrkracing54]

He certainly knows what he's doing but you might be surprised how affordable it may be also. Shoot him a call and find out what he has to say. Very nice guy. I spoke with him at speedweeks and he was very helpful even though I don't run Integras. John 1*

[TALON75]

Ya, don't be afraid to call him, very cool, nice guy. But be prepared to be told that what you want to do with the shocks and what they are built to do are two different things!

P.S.- if you want a cheap shock guy good luck with that! Chinese parts/tools are cheap but... Well you know!
