I'm getting new shocks and at the same time want to replace all related bushings with Poly ones. My questions: every bushing I see says exc- Type-R. So which ones do I get that will fit(I know the rear shocks are different)... Thanks for the help, and if you have part numbers that would be great. Ryan

 

Why are you replacing them?

 

I was wanting to replace them because I want a tighter feel, not the spongyness of the stock rubber. I auto-x the car regularly and would like the tightness... Anyone know?

I honestly have no idea what you're talking about.

The stock rubber bushings are fine, work on your shocks and springs.

 

Hmmm, I thought I've been pretty clear. I'm getting Konis to go with my stock springs(run D-Stock in auto-x). I want to change out bushings because Poly is harder than rubber, which is what I'm looking for. I keep looking but dont know which part number is for the rear Type-r control arms... Now how is this not making sense?

 

Well to start with Poly bushings are not legal in D-Stock.

Whats not making sense is your desire to get rid of the "spongyness" and "like the tightness".

You're dealing with a production tub that has nearly 350 lbs of unsprung weight and probably bushings with quite a bit of miles on them - replacing them with new, OEM rubber will be an improvement as well - they do not last forever.

And to open up a can of worms, the suspension components do not move only in one axis - and poly does not allow for this.

 

The mounting hardware shall be of the original type. The use of any shock absorber bushing material, including metal, is permitted. This does not permit the use of an offset shock absorber bushing. The bushing attaching the end of the strut to the body or frame on a strut type suspension is a suspension bushing, not a shock absorber bushing. Suspension bushings, including but not limited to those which carry the weight of the car and determine ride height, may not be replaced with bushings of a different material or dimension.

You may be right about my bushings being worn out, but if I can why wouldnt I just replace with poly ones. Probably same price or less...

For the lower shock mount bushings, there's probably no harm in using poly - but thats the only bushing I can think of that it would be ok.

There's no bushing in the rear LCA for the lower shock mount, only the front 2.

 

Mugen makes bushings for the ITR's
Also, the stock ITR bushing are hard rubber. They are stiffer than stock integra bushings, and are more appropriate than poly bushings. I've read in the ITR specs that the OEM hard rubber bushings were specially designed just for the R which makes them ideal for street/strip R's.

 

before you think poly bushings will help, why don't you just check and see how stiff those ITR strut bushings, etc really are. you can put an ITR strut bushing in a sock, and easily knock someone out with it. it's WAY harder than ES or Prothane.

 

I didnt know he was talking about the upper bushings, but yes dont use anything else.

The reason all the part descrips say "except type-r" is that the type-r shock shaft is smaller than other integras.

 

so if the shaft is smaller, why do OEM ITR bushings slide onto gsr shocks just fine?

They shouldnt - I had to have mine machined for the 12mm koni shock shaft, which is supposed to be the same as LS/GSR.

 

I got the whole ES on my car....then again its a GSR not an arrrgh. lol. Yes I felt a difference, was this because my bushings were 5 years old already? I dont know. As for the suspension moving in lots of directions. Well, I know that is true with the trailing arms. I dont know about anything else. Had my full ES kit on for over a year now, I have no complaints about it. Nothing broke either. Take it how it comes.
