bump stops - Honda Prelude Forum

So I put my order in with Lee, to have my Koni's shortened/revalved and the topic of bump stops came up. I'm just wondering what you guys are using for bump stops. Koni and GroundControl both sell foam bump stops. GC has the two different stiffnesses, stiff and soft. The koni ones, from what Lee said, are some generic racing ones that you cut to length. Oh, and these are going to be matted to a 500/550 GC setup, once the shocks get back home.

I'm using the 2nd from the left. Stiff Shock, they call it, from ground control. They're actually orange-yellowish, not white.

On a side note, what spring rate do you not have to run bump stops? And.. what if it were still daily driven?

I'm using the left 2 bump stops from Ground Control. The softer ones are in the front, and the stiffer ones are in the rear. Reason for that is because I daily drive the car, and when I spoke with GC they said that the hard ones are REALLY hard to the point where it gives an unforgiving jolt everytime you hit it.

I use soft Koni linear bump stops on my 3011s.

So this is what I just got back from Lee...

Quote:

Most of our bump rubbers are soft and progressive, only when the dampers begin to get challenged on stroke and available room do they tend to get a bit firmer and more linear. If you have the room to leave a proper length bump rubber, soft and progressive is definitely the way to so to keep the chassis from getting upset and limiting grip potential. Stiff or hard bump rubbers are very bad new and will most of the time upset the chassis and reduce grip if you hit them. With your Prelude on shortened front shocks, I would think the longest 12mm ID progressive bump rubber 15.34.20.000.0 at 55mm is going to be the one to use and the most common loose bump rubber we well. You can also trim it from the bunt end if you need to shorten it later.

So that advice makes sense to me, soft > hard. The front shocks are shortened, the rears are not. Would I be able to use the same length bump stops in the rear as up front?

Yea the rears would be the same as well. I'd say it's more important for the front since fully compressing the rears are rare.

Nice, thanks guys. I went ahead and ordered some Koni soft progressives. Now I just have to deal with the 6 week wait. *sigh*
