Bilstein Shock
Is this a good price for these?

How much better are they than the Stock shocks on a GT? Will the pair well with a set of Mazdaspeed springs?

it would be like $400 for a set. They seem to about $20 dollars cheaper per shock than most other vendors I see.
Here is another with similar prices

Power!!
The Konis are adjustable. The Bilsteins are not. The Konis have a pretty stiff jounce and adjustable rebound but the rears have to be taken off the car to adjust. I hear the Bilsteins are more comfy on the jounce.
Most of the Bstock Autox guys run the Konis. But the bilstein's are pretty new to the market. If I had to guess I'd say the Konis are probably better on track than the Bilsteins but the B's are more comfy around town and on the street. Either one will be a good upgrade you won't be dissappointed with though. So unless you are primarly in to tracking the car I would go with the Bilsteins...IMHO.

Think I'll see about picking them up then. I certainly don't think I need the adjustability and I keep reading the MS springs are no good to pair with the OEM shocks as they won't last long. $400 dollar + 7 dollar shipping seems like a steal.

You may just want to look up the part number here and match it with what's on that site

If you are thinking about autox, these are not legal for B Stock. They are a drop in shock but all dimensions have to be identical to be legal for stock and I think that the lower spring perch is a little bit lower than the OE shocks, thus not legal. For stock class autox the Konis are the tried and true winner. Myself, I am looking to sell my Konis to get the Bilsteins and have them revalved for STX class.
Also, the website is listing the Normal and Sport suspension variants of the RX8, all manual trans model RX8's have the Sport suspension, the auto trans models have the normal suspension.

the group I am going to autoX with doesn't have classes so I am ok there.
I just want something thats better than what I have just not super stiff and will work well with the MS springs.
I didn't know about the difference between the MTs and ATs in terms of the shocks, does the trim matter there?

*edit* To quote another thread:
https://www.rx8club.com/series-i-wheels-tires-brakes-suspension-55/brake-faq-167264/
Beyond that, I don't imagine there's another suspension difference between any models.
Brakes general description
The RX8 comes with either of 2 OEM brake systems. All models have ventilated front and rear disc brakes with ABS. The base AT model has 11.9 in. (303 mm) diameter front discs while the AT with sport suspension and all MT have larger 12.7 in. (323 mm) diameter front discs. Both models have the same 11.9 in. (302 mm) diameter ventilated rear discs and floating calipers. The larger front brakes have a different front caliper, master cylinder, and rear proportioning valve than the base AT model. Both models use single piston, cast iron, floating calipers front and rear.

I wasn't aware of the difference in perch height on the standard OE replacement Bilstein HD shocks, but if this is truly the case, then it's definitely a good word of caution to anyone considering this upgrade for stock class.

I think the trim may matter, further down in that brake thread, someone corrects the op about ATs with GT trims having the same larger calipers.
again, I'm running autoX with a group that has no classes so I am not worried about the SCCA (correct?) class requirements.

Or are you referring to another one?
The one I linked most likely refers to how the base AT trim has the 11" rotors in front. Any AT with the sport or higher trim (GT has the sport trim at least, I believe) will have the 12.7" rotor in front.
I believe the difference that could occur is that the base AT model with the 11" rotors was able to fit the 16" rims, while the higher trim AT and all MT models with the 12.7" rotor can only fit the 18". This may have a difference in suspension heights.

Either way, from what I undertsood, the standard Bilstein HD's were a direct replacement for the stock shocks on the '04-'08 RX-8's, and the OE Mazda Bilsteins found on the 40th Anniversary and R3 models were not the same (used a different perch height and were not rebuildable).

I think the term "direct replacement" means that it fits exactly the same as the OE shocks. It does not refer to the shock absorption and other attributes of the shocks.

i believe Shinka shocks are a slightly crappier version, as they would be a bitch to rebuild. The bilsteins are probably hands down the easiest customizable shocks on the market.
