Hey Gang,

After reading C.Ludwig's comments on shocks int he hybrid thread I figured I would take a poll of sorts. I am currently running KYB/AGX shocks in my `91. I had planned on upgrading them befroe the start of the 2004 season.

What is the general consensus about shocks applications? I don't plan on spending over a grnad per corner so the Dynamic Suspension type of setup is out of the question. I was thinking of the Koni's, but Chris mentioned the Bilstiens. What are the advantages/disadvantages of one vs. the other?

We run the Koni's. Grab them from Ground Control and have them valved for your spring rates. Mastguys run 500lb springs and under (front) so a revalve isn't neccessary. Leverone (fastest RX-7 at the ARRC) runs higher and gets valving specific to his spring rate range.

I'm new at this, so I don't have advice, only some limited personal experience. My car was built 5 years ago - I bought it last fall. It came to me with Koni Sports (8641-1200 front and 8041-1111 rear). They are continuously adjustable (no clicks) rebound only. One problem I've had is the adjustment changing during a session - don't know why yet. I have the stock front sway bar, and was trying to get the car less tail-happy by adjusting the front to near full firm and the rear to near full soft. I found after my last track event that one of the front shocks is totally shot - no damping at all. I have no idea if it's worn out or is defective or damaged. The rebuild cost is nearly as much as a new shock, so I plan to buy new replacements for both fronts this winter. Unless somebody changes my mind it'll be Koni Sport's again.

I understand that you need to be careful that your shocks can handle your spring rate. I run 400# front springs, and Koni said I am "about" at the limit.

Has anyone seen the new bilstein P30s offered through mazdaspeedmotorsports.com and their coilover sleeve for it?
 
Saw the new Bilstein set up earlier this morning. The struts appear to be the same Mazdaspeed units as the ones they market for the Koni Sports. The quality of those housings is very good, and they go together quite nicely.

Dave,

I can't seem to find the sleeves and shocks for the rear, there is little detail on these things. I called Mazdaspeed, i got was please hold, and held for several mins burning up long distance so i hung up.

It does not mention what types of springs it uses nor does it mention if there is a kit for the rear.
 
The rears don't take a sleeve. They are a shock alone. The rear Koni that is generelly used it the one spec'd for the Porsche 916. They come with the spring perch already attached.

Hope this helps.

Ok so now the question becomes, why is this setup so much better then the traditional ground control with konis or tokkico or KYB AGXs?

sorry for all the questions
 
I think it all boils down to personal preference and what is easiest for you. Some of us have the luxury to walk in to the Koni NA facility and get what we want. Others have similar situations with other manufacturers. Whatever fits the individual budget and is fastest.......
 
If you will allow a shameless advertisement/plug here I'd like to offer that I have a set of JRZ Shocks set-up for a Gen 2 ITS Mazda if anyone is interested. These are proven re-valved shocks that work exceptionally well.

Will be putting them on the Classifieds site in the next few days - NEWLY Rebuilt in 2003 to the new IT Shock specs less remote reservoirs (but let's not start another thread on that again)- 6 races in 2003 -

New with reservoirs they were $4500 - Spent $2000 in early 2003 on the retrofitting - Now will sell for $2000 with perches (no springs) and will share any set-up info as necessary. Will send direct contact info to anyone interested.

End advertisement . . .

Pauly,

I went to the Bilstein booth at PRI today, and asked about the set-up for our cars. Everyone there looked at me like I was from another planet, opened the book and showed me the catalogue with the non-adjustable street performance shocks, and said that was all they had.

I thought that was very interesting. I didn't press the issue.

I wish I would of know you were going. I had a ticket but stayed home to work on Project Street Miata mainly because I didn't want to go by myself again. The guy that gave us the hookup with Bilstein was supposed to be there. If you want Bilsteins Mazdaspeed or ISC can do the job for ya.

the company that makes the mazdaspeed bilstein coilover sleeves are http://www.awrracing.com

i called mazdaspeed and the tech people weren't there so i got refered to http://www.awrracing.com who makes the stuff for mazdaspeed. I didn't call awrracing.com yet to ask for specifics. I think i may just go with k2rd coilover sleeves with KYB AGX with their pillow ball mounts, then with Mazdatrix Caster Camber plates, Mazdatrix independant camber adjustment for the back.
