Now I have something for my car that didn't come with it, and isn't OEM-so I figure I can pretend to have a "build". (this thread has been re-purposed and edited, hence the firts few replys not making sense)

So I recently acquired tein basics from a nico member. Unfortionalty they're from NJ, and so rather rusty (and tein's all proud of their powdercoats.... I'm not impressed), but he had the threads packed with grease, which had saved the coating. I did have to take them apart and remove it all, though, to keep the grit from destroying the threads.

After some cursing at cam bolts and such, I got them in (I had to pound a few bolts out, hopefully the threads are not ruined and going to lead to my death). I'll replace the bolts and paint them better when I have more time and more to do under my car (I learned that one of my ball joints is totally shot, and the other's probably not far behind. So maybe next will be that and bushings), but this had to get done today, I have to use it to get to college tomorrow morning.

Yes, my car looks like crap in general.... but I think it looks infinitely less crappy now. And it feels much better.

Im not 100% sure what you are asking. But when i setup my coils i messured eye to eye of my stock struts and translated that to my coils to get the intial ride hight. From there i adjusted them a few times to get to the right height.

I *think* to get get the "top hats" off you need to have the coils under pressure so you can loosen the bolts. I don't know if that is the proper way or even what you are asking, just saying...

I think pictures would help greatly.

Well I was just wondering the stock measurement of the threads, I'm under the impression that the manual should come with some sort of little reference table.

I really wanted to get the front tophats off without pressure, because there's horrible gritty grease in the threads, and I don't want to turn the seats without wiping it off first. The front upper spring seats DO have spanner notches, but I don't know if I can turn them against the bolt, without stripping things or putting them on too tight, even if the bolt comes off.

And I don't think turning the top bolt, even with the whole thing laden in a vehicle, will get it off. I think that will just turn the piston against the damper housing. The fsm seems to say thats how you do the stock ones, though.

I'm currently in the process of borrowing a deep socket to get at the top nut, but I really need to know if it's okay to hold the spring seat with a spanner, to torque against-or if that would strip out, or overtighten, the seat, which I still need to get off to get at the mess underneath.

I did get tein to email me the manual, which is nice. But it essentially tells me to use magic to get the nut off. It says that you shouldn't use an impact wrench because it will scramble the dampers guts, but if you have to, don't come crying to tein, and that you shouldn't clamp the rod with anythich that could scratch it (ie. anything at all) and that, despite all that, the torque spec on the front in 42ft/lb. Also, their height suggestion is 1in from the bottom of the screws, which is the first point at which the spring actually is put under tension.... does that mean that's as low as the car can go? because otherwise I don't see how the springs could stay safely seated.

:woot:

-edit- got it, the upper spring seats are keyed, not threaded, and are acceptable to use to torque the nut. So without further adu, I will edit this thread and turn it into a pretend build thread. Or, with one day's adu.

Alright, pics whenever I can convince my sister to take them, but you'll be sorry for asking, my car looks like total crap. Like the total crap that it is, in fact.

I used the tein suggestion, which also happened to be as low as I could go without the springs falling out when unladen. Had to lower it onto ramps of stacked 2x4's, as my jack sucks... it'll be fun getting this in the air next time :naughty:

And now the rear looks inset and the camber's waaay off, and I had no idea how to set the cam bolts in the front, I just tried to make camber as positive as I could. So I'll have to figure those problems out. Might also have to do something funky to get it out of my parents driveway, and start parking on the street.

you need to get it aligned at a shop once you have everything in...

I totally do. And I'm totally not.

I put them in because the stock shocks where deadly and awful. It feels much better, but I don't have the money at the moment. And when I do get it, I still don't know, the local ripoff joint sort of makes what happens in the back a secret, and never gave me a printout from the rack of the before and after, and where real jerks in general (desk lady told them that key belonged to "the runt" last time I was there... ironic, as she's quite a "blob", if that's how it is), and charged me twenty-something bucks for new cam bolts. I didn't know what those where until I put the coilovers in, and now..... SERIOUSLY, twenty dollars for those? No way it needed new ones, either, I don't see what could have gone wrong with them.

So.... I didn't touch anything but camber as far as I know, unless it might change toe a bit? Steers fine, although straitens faster. I'll probably try to get more suspension work in before getting an alignment. I was going to get rucas (already set the cam bolts super positive, they LOOK right anyways) and just use a protractor/carpenter's square against the ground to check the laden camber, and adjust until it's in spec.

bump for blurry pictures.

And for spending a bunch of time reading about headlights, and still having no idea where to start.

I'm considering welding my own strut tower bars. I've seen different designs, including entirely solid ones with no hinges (fabricators on nico and elsewhere), and ones with hinges but no adjustment (like greddy) and length-adjustable (seem to be megan and such, maybe to facilitate installation in a laden state?). Any ideas on the best design? I'm thinking that non-hinged, single solid piece, if it's sturdy enough, should provide the best reinforcement, as well as protecting the car from metal fatigue the best, because the bar should absorb it all.... is this correct, is there anything I should know before building bars that are single pieces, designed for the precise FSM unladen lengths? I don't wanna sheer my strut bolts off, or something horrible like that.
