Icon2 racing shock adapters?

i was at work today bored and started drawing and thinking of ways to make it possible to run bilstiene or penske or koni racing shocks on our honda cars with an original clamp style shock on the front.

I have searched and really just found threads about coil overs such as the ground control brand that is ever popular with the road race and autoX crowd when combined with koni shocks.

the design is pretty simple and nothing that crazy but i would have to have some type of CAD or something similar to show you what i was thinking. the top hats have been made for other applications and i believe i have seen the tops for a BTCC Accord not too long ago but have not been able to find it again. However i have not seen the bottoms or shock forks.

Also is that i wonder if there isn't any BTCC race teams or serious honda racers with some financial backing that have fabricated something of the same design or similar.

I can post up pics of the shocks i am talking about or whatever else if some one has questions.

I use eyelet upper mounts on my Prelude with standard Honda lower mounts. Nothing special. I think it's more challenging on the Civic and Integras due to the short length of the front shock. The Prelude has more room.

I wanted to machine something out of aluminum, but the cost was too high, so I welded the mounts using mild steel flat bar and tubing.

I still use the Male/Female sleeve lower attachment point. Are you talking about fabricating an fork insert that incorporates an eyelet?

Where did you find that picture? It's of my old 3011s and new 2812s. Note the rears were way too short and had to be rebuilt.

You cannot use an eyelet on the front lower mount because it is not supposed to bend there. The eyelet will typically not fit inside the clamping area of the fork, so any adapter would waste about 1.5" of room. Best to chop the eyelet off.

Motons, they run about 3500 an axle I thing but they are race shocks, I currently use a set of custom valved FOX full body threaded shocks with Skunk2 upper and lower mounts. They have remote resivours, And adjustable rebound and comp. On a shock dyno I am a little behind them but hella cheaper. Call fox they will set you up.

You could probably make a sleeve that the eye-style lower racing sockets would slide into. Sleeve would keep it from bending/rotating, bolt through the sleeve and eye on the shock to locate up and down.

Basically you'd be building your own shock body (in a roundabout kind of way), which isn't too hard to do.

i understand that it is not supposed to bend or flex here. that is why you would have to turn the eyelet to be perpendicular to the axis of rotation ( axis of rotation being where the axis on which the LCA rotates.) an eyelet on a fabricated / machined shock fork would allow the shock to be able to bolt up.

MOTON is a very reputable company with shocks that are on a racing level yes, that is true. But i know that there are some people that would like to run the bilstiene or penske shocks.

HEY 117 think you got any pics of the flat stock eyelet piece you fabed so we can see what you mean?

I am more looking at the shock fork, because that is what i have not seen for hondas. the tops have been done i believe

This is a pic of the drawing i made at work. don't be critical with teh drawing as i can not do a 100% correct drafting style drawing of it right now. i was using a edge of a DVD case and a rite in the rain pen. but you should be able to see what i was thinking.

This idea won't work because the lower eyelet houses a spherical bearing, which can bend in all directions. So turning the shock sideways won't help. Also, you should not grab the lower eyelet because they typically are not designed for bending, only pushing and pulling.

You can look here for some other suggestions:

One idea that was mentioned was to run the front shocks inverted, and lathe up a cylinder that threads onto the shock shaft and clamps into the front fork.

If you want to run bilsteins, you can just use their regular sport shocks + a revalve.

You sent that to me a year ago... you don't remember? You use a locking collar versus the set screw for the spring seat?

I believe that one of the biggest advantages to running the double eyelet shocks is the ease of rebuilding, and being able to revalve yourself if you have the right tools and some knowledge of the shocks.

You are correct though turning the shock eyelet sideways with a spherical bearing would still allow it to flex and act like an elbow with the shock fork. Like i said this was jsut an idea i had bored at work with nothing else to do.

has anyone made or seen the double eyelet shocks inverted or the piece to invert the shock that would fit either in or on an original shock fork?

thanks for the replies and informative posts

I don't understand your fixation with the eyelet shocks. Any race shocks can be made with eyelet or not. If you order a race shocks they will ask you what kind of mounting do you want. The only reason why there are lots of eyelet shocks is because they are mostly made for tube chassis race car.

OEM Bilsteins are just as easy to rebuild as the double eyelet versions.

As 117 mentioned, Civics and Integras don't have a lot of room for the shock absorber in the front, so you don't want to waste space by having unnecessary eyelets, even for the top mount.

You can get pretty much any flavor Koni with mounts for any common Honda product... ie 8041/8041 Race valve/3011/2812. I'm not sure why you're going after the eyelet shocks. Eyelets may potentially eat up shock travel which is in somewhat short supply to begin with on these cars.

Re: inverted shocks
I believe Koni had an inverted-mounting option for the 3011s available for Honda application, but isn't recommending that option due to shaft side-loading issues. At least, I think that is what Koni Lee mentioned. Remember most of the Honda suspension bits move in multiple planes.

Unless you have a shock dyno at home, I doubt the average end user intends to rebuild their own shocks. I don't see how the mounting system would make them easier or harder to rebuild.
