fully threaded damper for coilover

Whats up zilvians ive been out of the game for over a year as far as upgrading goes after parting out my old rb25 s13. Now for some time ive had a q45 g50 and im ready to start upgrading suspension. now this time i dont want off the shelf coilovers, i want to design mine from the ground up. hopefully someone can chime in whose been down this road before:

where can you buy the damper by itself with no mounts, that is fully threaded? ive searched every where on the net and always find ones that are partially threaded with a built in mount. im looking for bilstein or something high quality that i can run aggressive spring rates.

it seems like at this point ill have to get blown coilovers and have the damper rebuilt. btw the q45 uses basically the same size suspension as z32 and skyline.

im basically in bed for the next few days after getting surgery on a blown knee. if anyone has any advise or input i would be very happy to hear it. espcially if you have ever personally rebuilt a damper or found a new one that is threaded without mounts.

i suppose the only other thing i can think of is having a machine shop cut threads in a blank damper but that sounds shitty. thanks feel free to post here or pm me.

Cool yea i have explored the koni 8611 option. i think to make things easier im going to use s13 rears with custom valving and z32 mounts.

basically trying to figure out length difference between z32 front and s14/s13 front if anyone knows?

z32 front isn't mac strut.

S13 rear with z32 mount doesn't make any sense at all. Just throw on a z32 rear shock.


Z32 koni yellow works in back if you're trying to save money.

Many coilover companies sell just the damper 'cartridges' as replacement parts.

Megan lists the lengths and specs of all their dampers on their website, which makes for a good reference point, since other companies most likely use similar lengths for the same application.

I have a friend who supposedly was able to get bilstein units, but he cant get ahold of him. they were fairly cheap with a huge 52mm piston but ive looked all over internet with no luck. i guess i have have my heart set on bilstein dampers but are nowhere to be found, im gonna call bilstein tmrw

What you are asking us to find for you does not exist. I have never seen an individually sold threaded damper unless it was a replacement part for a coilover setup. Koni and Bilstein do not sell just the damper with a threaded body. I would use Z32 front and rear Koni yellows, maybe have them re-valved if you're going to run stiff springs, and a ground control setup. As I recall the Z shocks are just a little shorter than the Q45 shocks, but that's fine since you're lowering the car anyways.

Im at least wanting a monotube, pbm makes dampers for a 100 a piece and i could use them as a starting point. Not sure about their valving options, maybe a fixed mount coilover is all i really need.

Why do you want a monotube shock? The twin-tube Koni's are going to ride a bit smoother than a monotube Bilstein from my experience. The Koni yellow/GC setup is the closest thing to what you're looking for for a reasonable amount of effort and cost.

To have dampers that don't leave you screwed on warranty, to have dampers that are easily user rebuildable.

Ride quality is subject to valving, you already know that, not to mention the ability to run a base valve with a monotube for any minute difference in driver "feel" twintubes wont get the same sort of repeatability of a monotube, not to mention increased stiffness of an inverted monotube up front, or the possibility for reduced unsprung weight in the rear.

OK OK, you're a Koni hater. I get it...

Typically twin tube dampers have a more comfortable ride feel. That may or may not be due to the fact that monotube dampers are typically valved more aggressively. Shocks do not increase stiffness, you should know that.

As far as "user rebuildable" pretty much nobody on pretty much any forums has the equipment to properly charge the shocks or the expertise to do the labor themselves. I do not see "user rebuildable" as any sort of valid argument. Bilsteins are however cheaper to rebuild/re-valve so there is a point to the cost.

Some people are hardcore for Koni's some people are hardcore for Bilsteins. BOTH camps are firmly entrenched in their positions. Attempting to argue which one is better is purerly subjective.

In all honesty, I prefer Bilsteins from my experience. Unfortuanetly there are not really any realistic or affordable Bilstein options for the S-chasis. Anything Bilstein would either have to be imported and would cost cubic megabucks, or it would have to be fabricated and a PITA. If they made Bilstein PSS9/10's for the 240's like they do for my M3, I would be all about them.

No, that i'm not, the warranty thing is just one of the reasons some people choose to run Bilstein, or other options, honestly the Konis are good dampers, and a great choice for some people, but hey I've got more bilsteins and penskes than reasonable for one car. It cost me less to build a setup with more adjustability than konis, for some this wont happen, but either way, koni, kw, bilstein, Penske, and ohlins are all options I definetly don't hate.

Yes "typically" but as you yourself admitted its subjective to valving, so why are you mentioning it to me when I've already said that ? Also as I already mentioned Base valves are an option for monotubes to improve driver "feel"

I'm just going to say you're flat out wrong on this statement, I guess either you don't know what goes into it, or you like to make it seem harder than it really is. Yes most people around don't have a nitrogen filling station, but realistically local tire shops will fill them without issue, there really isn't a lot of "expertise" needed for a basic rebuild, yes I would say most around here don't have the expertise to revalve and make improving changes quickly and easily, but simple rebuilds don't take any voodoo magic.

No, it isn't, the fade due to heating the oil in a twintube compared to the better cooling of a monotube cannot be refuted, the "driver feel" of a typical off the shelf twintube I wont refute, but again it can be matched with a base valve, leaving the upper hand still to the monotube. Also the improved resistance to flexing of the strut in a macpherson strut car using inverted monotubes vs twintube also gives an advantage to monotube.

Mine are sorta in that fabricated PITA category, of course I've got a few extra setups i'll be selling off soon that wont be megabucks for a few people around, the pss9's aren't anything good with their adjuster, I've actually got two of them that will probably stay in the extra parts pile because putting them together in a complete setup seems to be a waste of time compared to the bilsteins I've got assembled using ohlins, and Penske rebound adjusters.

No bilsteins dont have any "huge 52mm piston" apparently you're lost, some bilsteins do indeed use a 52MM OD BODY but none use a 52mm PISTON, they use 36mm and 46mm

Apparently you haven't done much research if any at all here and are just talking based off of the little information you have.

You wont likely be using any moton pistons here, even though I haven't found a specific diameter on them, I HIGHLY doubt they're the same as the bilstein, and the ohlins piston idea wont work for much up front as finding 36mm Ohlins pistons seems to be like finding hens teeth, and even if you could, you really wouldn't likely be able to gain much over bilsteins digressive, or the cob/rbt digressive 36mm piston, for the rears sure you can use some Ohlins, of course by the time you pay what ohlins wants for a pair of their 46mm pistons (what the Bilsteins you tried to say use 52mm pistons, actually use), you could have bought 2 Penskes, 2 different types of pistons, and a valving kit.

Also that JIC damper wont get you anything usable other than a threaded housing that matches up with nothing else dimensionally.

I think the OP should apologize for starting a big olé argument......

Seriously though we should get the thread back on target and save the what's better than what discussion for NRR where I know you 2 are members.

@ racepar ... You can follow Ricers Bilstien thread @ NRR as well. Interesting info.

Seems to me the OP is stuck at easy to put together vs. Megabucks fabricated one offs... If money is the object it'd be hard not to just go Koni for daily duty, or even some other JDM Tyte Yo coil over... Eibach even maybe...
