My thoughts exactly. For that price you can get something that rides well and has adjustability.

show me one set of coilovers for 1200 that will have the ride quality and last as long as the bilstein/spring setup and I will be all over it... any of the sub 2000 coilover systems are just brutal unless used only for track or hardparking

True, if you want some questionably made and harsh riding coilovers. Any coilover with a smidgen of ride comfort will set you back atleast 2k+. This is for entry kw's, hr coilovers, bilstein pss9. Or you can buy my used kw's for 1700 with springs rates that actually work!

I want to upgrade my GSR to Bilsteins. My plan is to use them in conjunction with a slight drop that something like the Swifts would give me. However, now there is a bit of confusion because apparently some 2005+ GSR received Bilsteins as OEM equipment as opposed to KYB's? Lancershop shows two types of Bilsteins.

I'm guessing I want the yellow "HD" models and I would then have to buy MR type lowering springs, but I was just wondering if someone could offer a bit of clarification - as I am guessing the more expensive (on their site) but non-HD "silver" Bilsteins are comparable to the standard KYBs and don't offer a performance upgrade - even though they say some MRs got them:

Only Evo that came stock with Bilsteins was the MR version, GSR had KYBs.

HDs are the replacement struts from Bilstein. Their valving is slightly firmer than the OEM MRs.

Thats just a stock file from Lancershop. Bilsteins are yellow.

I ran Bilstein HD (all four) with GSR Swift Sports and SpecRs.

Yeah, that's the way I understood it, until I saw that second link for the first time.
I am hoping they still offer a smoother ride then my stock GSR KYB's as that is my number one concern. I had been under the impression that you HAD to have MR style springs once you change, but I think now I see that it doesn't matter and that they are interchangeable. I would rather have the GSR version of a lowering spring that doesn't drop the back as much as I have a sound system. I will most likely go with the standard Swifts. Thanks for your help.

Yes. The HDs are softer than the KYBs. Just a little bit firmer than the MRs.

For Swifts, the MR drop the rear less by .14in.

Swift Spec Rs: F: 157 (helper section) 358 (main rate), R: 196 (helper section) 380 (main rate). -1.4, -0.8 drop.

Swift Spec Rs MR: F: 157 (helper section) 358 (main rate), R: 153 (helper section) 380 (main rate). -1.4, -0.66 drop.

Not true. I have bilstein's PSS9, sub 2000, and the best dd coilover system you can get. Of course, they aren't $1200 (unless used) but if you have 2000 as a budget, get them, without even thinking.
On the other hand, if I had to choose fixed struts I would go with the HD's and springs.
FWIW I got stock KYB (blew one) then got MR bilsteins ( did not like them AT ALL, way too soft) and finally went for the PSS9 ( only because I got tired of waiting for the HD's to become available).

GPTourer

Uh, oh - is that not backwards from what I read here?:

Gas pressures are different in the MR Bilsteins. Rear MR springs are 3-4mm higher than the GSR versions. Reason is for the increase pressure the Bilsteins have - as tested by Swift.

I hope it's okay to bump this useful thread. I just got my IX RS and I've found the ride to be remarkably rigid for a production car. It reminds me of my old Neon ACR with the struts set at full stiff. This makes for a crisp ride on the street which I certainly don't mind but might not prove the best in the dirt. From what I gather here as well as some other threads, the MR Bilstein setup is slightly more compliant.

If you are on the OEM KYB's, they pretty much suck. Bilstiens + good springs, not only handles better, it rides a lot better. First hand experience in my case.

My particular setup was HD Bilstiens and Swift SpecR's. IF I hadn't conveted my car into a dedicated track machine, I would still have that setup on it for DD.

Is lancershop.com the only place to order the bilstien HD`s? I saw them at tirerack.com, but it looked like the fronts were HD and the rears were not... anyone got any clarification on this as I am planning on doing this set up very soon and last time I was on lancershop.com I could not find them on there.

I wondered about this too and even argued with friends about it and why Tirerack listed the rear "HD" and the fronts "Sport".

If you look up the part number for the "Sport", which are the fronts, it will come up as "Bilstein B6 Heavy Duty".
This website has both with the part numbers.
http://www.eshocks.com/bil_Ind.asp?VC=92Q24&SubChar=Q

This website also has both front and rear listed as "HD" with matching part number from the link above.

And lastly, I managed to find a thread about this.

Asking the same question on HD and Sport.
Neal@tirerack's response:
And there you have it. What's listed as "Sport" is actually "HD". There is no "Sport" for the Evo.
