Edit: crap, you're right. I'll fix it shortly.
Edit #2: I just moved my site to a new server; it might take a few more hours for your machine to see the new location, but it'll work soon.

Thanks!

Thanks,

I'd be curious to know what you come up with for the STi and the RX-7. I was pretty suprised by my initial analysis of the RX-7. Stock, it looks to have a strange set of natural frequencies and a crazy amount of rebound. I wonder if all the extra rear rebound is to keep the lower rear frequency in check.

When you have something, let us know!

Any chance of getting the pics updated? I see red-X's...

I'm not sure where they went. They are stored in my basically unused iwsti blog. I don't even see the link to get to the blogs anymore

. Any chance you came here after visiting Dennis Grant's site?

I've read DG's site, but I was linked from TiC's site in their TiC SST Coilover product description... very curious to see the data...

Alright, I've tried following this thread for a while now. I get the Jist of it, but not all of the details.

I began reading with 1 simple thought in mind. "For stock springs, and a SCCA Stock class legal strut, are Fixed perch Ohlins my best choice?" (are they my only chioce still?) I only know the stock struts, but they are noisy as hell now (on my replacement rear pair from subaru)
Also is there any way these struts are working properly while clunking like that? ??
In this thread its written they Stick , that seems like both that they do, and like it would be Bad for performance if that initial body roll sticks , when it unsticks does the chasisss roll faster then it would have with out sticking?

*confused in Stock class* :P help!

Since this thread is all about numerical analysis of different setups, there is not much to say about the Ohlins FPS since no one has a damper plot of them. Many of the gurus around here like them and I'm sure they would be a great choice. Other choices would be Prodrive (if you can find them). With some work you can also make Konis work.

Assuming i buy those i could let them be shock dynoed if who ever is doing that lives around Nor Cal ? hmmmm

Yes, you could do that. If you do, please share the results with us!
