Hey, so i've been researching about shocks and springs now for about 3 months. and i feel like instead of combining a shock with different springs i've decided to just buy a Bilstein B12 kit. but for some reason, every website i try to purchase them on, i get redirected to the bilstein B6 (HD) kit. i dont want those. i've called bilstein's main office and they said they dont make B12's for an Rx8. but i've seen people put B12's on an rx8 before and everytime i ask where them got them and if they had to modify it to make it fit, they fail to answer. so i feel like it's time to post a thread about my problem. Can you guys please send me a link or give me some info on where/how to purchase them? I'm just trying to finish up my suspension upgrade before i leave for the Air Force.

I would really appreciate any help.

 

I read somewhere that B12 were a European Bilstein variant. But I also got impression that a Euro B12 was same as a US B8. Not sure sorry.

 

I thought Google was invented ages ago.

 

i tried google. it just takes me on the same path, it starts me off looking at B12's but once i'm ready to purchase it, it just links be back to the B6.

 

theres B12 on their site but are you sure they make those for rx-8's?
only B6 and B16 fits according to Bilstein.

 

People have posted they have B12 kits on their rx8. so i'm assuming they do have them but they are just a pain to find...and the B16 doesnt interest me either. i have my mind dead set on the B12 kit. i'll get them eventually i'm not gonna give up.

 

I have 42K on my stock shocks (brand ?). I am just now feeling them loose their firmness. I put Bilsteins on my '79 RX-7 at 30K miles and put another 60K on them no problem.

 

Just get the HD's, they rock!

 

R3 has the B6 HD I think.

 

I'm wondering...... How many miles are people getting out of there stock shocks before they feel a need to replace them?

 

If I'm not wrong... the B8(s) are the ones that you're supposed to use to couple with lowered spring... B6 is for the stock springs.

 

As a generalisation, what you've stated is correct. But there are springs and then there are springs. Tein h.tech afford such a small change in drop that you can still use B6 even though technically you are lowering the car.
