The Better Bilstein Ebay Coilover Thread

Ok, that sounds reasonable. I just don't think i can get a full 1" of travel from squishing 31mm bump. 1"=25mm so 31-25=6mm. That would have to be a super soft bump in order not to become a very stiff virtual spring at that point. I'm going to inspect my mounts/shocks again and see if there is anything wrong with install or parts, but I've looked at them a few times already

Quick (Stupid) question. I just got extended rear hats in the mail (Thanks ISC!) and I'd be right to assume that if I left the spring perch in the exact same spot and just changed out hats, I would lower the car right? Thus a change in top hats means I need to raise my spring perch a bit?

Does anyone have a suggestion where to buy bilstein circlips to use with OEM bilstein take offs? When I removed the spring mounts a few got bent. I know a lot of people used the rotor clips early in the thread, but since I'm using all star sleeves I need one that resembles stock, so the sleeve can fit over. Summit Racing has a one MONTH wait to get these, no auto parts stores have them, hardware stores, etc. Any suggestions?
It looks like amazon has them for 5 bucks a piece

Yes, those are the fronts.
Small update - so far so good with install of TSM hats. I haven't gone much lower (even though I have maybe about an inch left on the sleeve), but at least now I have shock travel before bumps engage. Went for a short test ride - so far so good.
Notes on TSM hats: decent quality (not high end like Xida or Feal hats). The hole in the hat does not accept the nipple from the OEM lower bushing. If you want to use it - you will need to enlarge the hole. I've just used some electric tape until hat was snug against it. Should help with centering and preventing noise and some vibrations. Lower bushing is too big for this hat in general. I've used MCU bump cut-offs inside instead of bushings and then OEM bushing on top. Hat is lighter than stock, dimensions are spot on, the spring locator is a nice addition.

I've called Chris from TSM and he didn't say it was for NA - said it will work for me just fine. I don't think it's a good idea to not use a lower bushing as this will directly connect shock to tophat and provide no isolation from NVH. With a solid metal to metal connection, this will be noticeable in the car.

Finally got my bilstein setup on, sorted and tested on both daily commute and track.
NA bilsteins
Allstar sleeves
Eibach 7 inch 450 front and 7 inch 300 rear
12.5F/13R
New DC2 integra Bumpstops (trimmed to 36mm and V-cuts to make engagement progressive)
Front:
0 Toe
4.5 Caster
1.7 Camber
Rear :
0 Toe
1.7 Camber
Wheel/Tire setup
185/60/14 Nankang NS2-R 120 Treadwear
14x6.5 Panasport Prorally
Sway Bars
Stock R package sizes (S-special type I is an R package with power windows and AC)
Results
Excellent ride dd for most but not all bumps I think the springs are still soft enough to jack down on bumpstos, great turn in response, very light understeer on corner entry and perfectly balanced mid and exit with a torsen.

Hmmm. Need to get back to this - I have some ideas for what I want F/V curves to look like, a disassembled digressive circle track Bilstein that I took measurements from, a dyno plot on a DIY dyno I did with the shock in question, and a copy of Restackor... seems like it should be possible to fiddle the geometry in Restackor until things correlate, then try to predict valving for F/V curves. I mean no disrespect to any vendors or pioneers, but now looking at data people have published, it seems like there's a certain range of stuff that works pretty well at getting close.
Or maybe I have delusions of building my own runoffs grade shocks, whatever.
