Wow finally a good rebuild video, that's how you do kids! except that you can get a C clip pliers. My wife hates when I do mechanical work on my living room, last time I made a mess with DOT4 hydro oil. Thanks 4 the video
No problem man. You are more than welcome. Lol and yes, I too as well had complaints of using the dining table as a workbench. Hehe. I now have a dedicated work bench in the garage.
Make sure to Google the “GS300 diy shock revalve” post on clublexus.com it is way more thorough than this video and somewhat guides you on how to perform the math behind making shock shim selections and how to do a full scale shock revalve to achieve what you want. This is was calculated using the BC racing shock body with Bilstein internals and the Bilstein shock revalve manual.
Thanks I'll. The ones you made is pretty good too. And gives me some ideas I'm thinking about getting a Megan and upgrade the internals and a swift spring to see how's work. Thanks man keep up the good work.
+pvflyer67 no prob. I may be wrong but I think Megans are a 45mm internal diameter piston and not the 46mm that the bilstein’s are. Not sure if you have a whole set of Megan’s yet, but before buying a full set maybe invest in just 1 replacement strut cartridge for your car and open it to take measurements.
No, I have not bought the Megan's. I am in between the Megan and BC's. What I don't like about the BC's is the rear shock design they have for my car. But I may have to leave with that. Again great info and thanks for sharing with me. Megan website sucks if you're looking for technical info about their products. It would be nice if they've a spec technical sheet.
Dude you're the mad scientist, love this video. I just bought the DR(digressive) series and I want to see them on a shock dyno before doing a build like yours. good job man
Watching you swinging things back and forth right over the top of an unstable tube of oil on the table I was just waiting for you to bang into it and spill it all over the place!
No problem Daniel. Anytime! Its been a while but I have a little bit more that I want to show. Please visit the clublexus website post for far more details and the true/full step by step.

Good job. The sliding or dividing piston as you call it is normally called an internal floating piston. The placement of this piece is extremely important as if it's too high, it can hit the main piston and if it's too low the shock won't ramp up properly and the end of travel. I wonder if BC would give us this measurement??
I did not have the exact measurement from BC racing, so here is what I did. I took the partially BC racing assembled shock body and compressed the shock shaft to its lowest point of travel. And then measured the distance from the very bottom of the shock shaft tightening nut (while shaft is compressed) to the inner most point of where the shocks "butt plate" or bottom end cap would be inside the shock body. Once I find this distance, I would then divide it by 2. and this is where I would place the top side of the "dividing/sliding piston" at.
Thanks. I'm going to call BC and see if they will give these measurements. The IFP depth and oil height are both super important. I'm glad to see these are easily rebuildable and customizable. How do you like the bilstein piston vs stock??
I just talked to BC Racing and they don't publish specs on how to rebuild shocks. That's unfortunate - but I'm really glad you made these video's. I hope other people DIY and share the info they find. Thanks again!
For general track use, then yes I recommend them. Even for regular street use they are ok. My issue was I wanted the most control in body roll, but without having to "stiffly" feel every bump or dip at 70mph on regular roads. These coilovers, and any 'linear like piston' coilovers will more than likely exhibit this issue. Google ksport, megan, fortune, bc, ohlins, AST, Bilstein shock dyno graphs and see if they are linear or digressive. Read through the clublexus post link in this video description. If you have any questions feel free to ask. Hope this stuff helps.
Hey man if I was to purchase BC racing digressive valve shocks can I keep the existing shim stacks in compression and rebound and just out in a COB bilstein piston would that work?
I would no to that. Physically, yes you may be able to have the parts all fit together, but the performance more than likely would NOT be desired. Without getting too technical, the only small way I could see your question working and matching up with the results of the Clublexus shock revalve tutorial writeup, is if BC Racing made their BC digressive piston’s design parameters match up to the same design parameters of the bilstien COB piston.
@@drunktortila3632 You are welcome man. Anytime. Keep in mind this does not mean that you cannot modify the BC racing digressive piston. I have not see the BC racing digressive piston personally, but I believe you can modify the existing shim stacks to get desired results. The only issue is that if the BC racing digressive pistons design features ( I dont want to go technical here) do not match up with any variation of the Bilstein digressive piston design features, then the Bilstein Digressive Valving manual would be useless to you on your endeavor. You would be revalving by trial and error whi is basically using a shock dyno and computer to plot your results after every shim revalve to see if you finally have your shim stacks arranged to give you your desired graph/results.
Francis Lucas The stock BC BR valving characteristics are a linear setup. The Bilstein valving arrangement is a digressive setup. If you have a chance google “DIY Shock Revalve Clublexus” and read through my tutorial for an in depth explanation.
Alex yes BC does, but I removed them and installed the Bilstein internals and custom valves my suspension shocks for a way far superior ride using bilsteins valving manual. Google “clublexus diy shock revalve” and read through my step by step tutorial.
I love this Bilstein digressive piston setup more as it is far more comfortable at highway speeds especially on imperfect roads when the adjustment knob is set with cornering/body roll as a priority. (Less valve bleed) This is versus the original bc racing linear profile Keep in mind for those wanting to do this, if you read through the tutorial on club_lexus, the bilstein valving manual is intended only for the bilstein piston valve. Not penske, ohlins, etc valves. .
so the bilstein is a "50/50" valve as you called it - while the BC has larger orofices for compression than for rebound. With this, shouldn't the bilstein be stiffer on compression than the BC - all things being equal?
+Chuck Davis the rebound orifices for the BC racing piston are way more smaller in size when compared to the compression orifices. Which yields the higher rebound forces shown in the shock dynoes on the clublexus forum post tutorial.
+Chuck Davis the Bilstein pistons shown in the clublexus forum tutorial are a 50/50 piston as the orifices for both rebound and compression posses the same area for fluid to pass. So the shim arrangement is of more priority as the shock profile is determined by this. Because this piston is a 50/50 orifice piston, it is more versatile in my opinion.. The same applies to the BC racing piston, but for example less shims would be needed for the rebound side as the orifices on this side are smaller.

dude thank you for taking your time to edit and post this vid, shoutouts from Peru.
No problem. You’re welcome.
Looking at getting a second hand set of the BC BR... Thank you for this video!
No problem, you are more than welcome.

Thanks Armstrong. I have more vids to come on this project soon. Stay tuned.. 👍🏾

Thanks for these videos, Frugal Fabrication. I really appreciate the detail.
Hello from Melbourne, Australia.
No problem Daniel. Anytime! Its been a while but I have a little bit more that I want to show. Please visit the clublexus website post for far more details and the true/full step by step.
Hello, I'm looking to rebuild a set of BC RM inverted coilovers. Is it possible to do this same rebuild with the RM series?
How do you first relieve the pressure?
Hey bro where on line can I get the replacement seals at for the rebuild
