what are the differences between the two? what kind of drop, if any, will there be?

 

itr is slightly lower then stock, and the struts and springs are a little stiffer.

 

And you'll need ITR rear LCAs if you plan on getting them.

 

You would probably be better off just going aftermarket. Like Koni.

 

I did it a while back. Neutral observations:
-Slightly lower but not a noticeable height change considering that I've seen a lot of stock Honda's with suspensions sagging to this level from age anyway.
-It rides fine, same as stock, if not slightly worse over bumps.

Positive observations:
-Seems to handle crisper to me, but this may be subjective.
-It was cheap even considering that you have to get the ITR LCA's too.

Negative observations:
-No choice but to get used (dealer still sells?) so condition unknown other than what seller says.

If I went back in time I would have just gotten new aftermarket, especially for you since it seems like you are interested in lowering. Looking back, the unadjustable KYBs or Koni's paired with stock or Tein springs really aren't that expensive.

 

Well, reason I asked this was because I have two different people wanting to sell suspension to me and I have to make a choice. Tokico Illuminas w/ neuspeed springs 1.75/1.5 drop, or full ITR suspension including LCA's. I'm definitely leaning toward the Tokico/neuspeeds though. seems like a much better choice to me.
