That's pretty similar to my setup. I used to have 450/325 on Bilsteins that were great if not a bit soft on the track and a bit harsh on the street. Now have 375/250 on Koni Sport. On the street - Koni's on softer springs ride better. There is significantly less NVH over surface with many small imperfections. I haven't taken this setup to the track yet, so no feedback on that.

 

 

Finally got these and they are all kinds of wrong, bolt hole is too small and needs enlarged. Sleeve width is way shorter so washers would be needed. Quick check of the OD shows .020" worth of press fit which is a lot. Might have been worse because of the paint I put on the shocks.

I'd pass on these.....

 

Damn, sorry to hear that.
Chalk it up to random Chinese parts made 5 years apart I guess?
They worked fine for me other than needing to enlarge the bolt holes as I mentioned earlier.
Again, sorry to lead you astray

 

 

Yes, they must be shorter.

 

 

did you see if sleeves have different depth inside perch? I've seen sleeves that when installed one way - sit high and when flipped over - sit lower because of where inside lip is located.

 

 

I have some bits from my MSM billy project posted in the classifeds:
https://www.miataturbo.net/miata-par...oarding-97036/

Eibach 2.5"x6" 700lb. 1 pair.
FK (german) helpers. unknown rate, unknown block height. 60mm ID, 82mm free length.

 

 

TLDR;
built a set of nb sport bilsteins, why does it bottom out or rub so hard? should I raise it more
QA 550 7" up front
Eibach 6" 375 in the rear
FCM bumpstops
NB top hats

94 M chassis

Driver side rides fine when on the street, hooning.
Went to school in the city, twice in one day my shock bottoms out or something,
i've raised the rear from ignorant to two finger spacing between tire and fender,

Don't understand why it bottoms out, and stays rubbing the tire like crazy, until I stop on the side of the road, lift up the corner, and shake and see maybe I was an idiot and didn't put the spring isolater on that corner or something, I was supposed to get an alignment tomorrow,

Seems like an asshat move to get an alignment and then have to take it apart for some reason

Waiting for it to dry to see if I do infact have the spring isolater installed, my only theory that under a huge dip the spring wont set right?
or my 'tested perfecetly 30k bilstein' is actually shot

 

What is your ride height? Sounds like multiple things at play here. I don't know how large the FCM bumpstops are but you could very well be bottoming out your bumpstop especially with stop top hats. Tell us your ride height first and we can go from there.

 

If it starts rubbing and keeps rubbing till you lift the corner you have something broke, dislodged c clip most likely.

Did you have the tire up without a spring to verify you bump stops are trimmed correctly? Doesn't sound like it.

 

C clip looks mighty fine, i am runing the roto sh-196 c clips on the ground control / eibach sleeves

I recently disconected the rear sway bar/end links, but that doesn't seems to affect the ride height??

46mm FCM bumpstops

12.75-13" passenger rear
12.5" driver rear sitting in the lot

I got a photo from the rear bottom, i'll take the wheel off in the AM, but it looks like it went through the spring isolator? or compressed the **** out of it

 

Spring isolators just keep the springs from creaking, won't affect ride height or cause the suspension to stick I'm a lower position.


​​​​​​You got issues, tear it apart.

 

tore it apart, everything was fine, double checked triple checked
checked the arms, everything.

only thing left is the shock
procceded to put all my weight on it,
compressed the shock
stayed compressed,
had to pull it up by hand but slowly went up on its own
pretty sure that's blown no?
no oil anywhere though, the seal is fine also

tldr: it's cheaper to buy new bilsteins than revalve

 

If there's no oil, betcha bent the shock shaft. Check it with a strait edge.

New is always cheaper than a rebuild with these shocks.

 

going to tear the rear apart after my physics exams on wednesday
Re torque all of the control arm bolts
After reading through pages of the bilstein threads
I read that even after revalves the "gas-less" wont come back up on its own, dwant to buy new OTS bilsteins just to keep having the same issue potentially
So i'm thinking I am having this as a result from my 375' 6" eibach rear springs
Coil bind?
assuming this is fixed when i order 7' 325 rear springs
I am considering 1" extended top hats in the rear, but also read that the coil bind is real unless hellalow
progress? im not sure<
