Correct. However, the first time I attempted to install this, I actually used both the stock and the Megan tops bolted together with the bearing and everything, and the pistons still came way out from the tops of the strut towers. After calling Megan, they said I am only supposed to use the red tops that they supplied. There was no mention of the strurt bearing, though.

so you'll need to press out the stock strut bearing from it and transfer the bearing over to the new coilover. If you can't push it out with your fingers, then try tapping on the outside race gently or a wooden hammer handle should do the trick. Then the nut (which I don't see in your diagram?) will go over the bearing before the rubber part (which fits around/over the strut bearing).
Okay, assuming I need to take this part out and it does fit the Megan units, how much do these need to be preloaded?

Yes, you must use a strut bearing always on this type of suspension.

According to the repair manual the torque on the nut directly above the strut bearing is 25ft/lb. I usually use an air tool on it, but you don't want to over tighten it so you don't damage the bearing.

That is the way we did the installation. I'm not sure if we needed the bump stops (not used) inside the oem rubber.

No. I beileve that spacer is actually used as a stop for the only nut that I used.

Did you use the stock strut mount bearing?

Also, you don't by chance have any pics of the shock towers after the install?

Out of curiosity, can someone explain to me why the shock pistons on my Megans raise up through the towers, but the OEM ones don't?

Okay, I finished the project last night! A big thanks to all that helped, especially 03Z33! It's very simple once you figure out what parts you need! I couldn't believe it, really. This whole thing could've been avoided and done (with hand tools and two people) in around an hour or less if I had known exactly what parts I needed.

Here's the deal (I took a pic, and will post it later): For the front Megan struts, you must reuse three stock parts: The strut bearing, the nut on top of the bearing, and the rubber support assembly (The big black rubber donut on top). Basically take the strut as you recieve it from Megan, take the stock strut bearing and press it in place (yes -- use the little metal sleeve, too), tighten it down with the stock nut, and then put the stock rubber support on top of that. Then you can install it as you would any other strut assembly. I'll compose a detailed write up later.

I drove home (with a ton of tools and stuff in my last night), and I will say this: even on the "full soft" setting, these are very stiff. However, the car now feels like a go kart! The steerig response feels so much better! Although these are probably not for people looking for a soft ride, they should be great for autocross and/or track use! I can't wait to do my favorite twisty road with these. It feels like a racecar!

I'll give you more info next time I'm able to drive it more.

Cliff notes
Use OEM strut bearing, nut and large rubber donut on top
Ride is stiff, improved steering feel

Man what a struggle. I've been interested in your progress, but could not help.

I'll look for your writeup, but think if I get these I am having the mechanic install.

Yeah, I started it it at 11:00am on Sunday. Got the rears done in about an hour (after trying to figure out which OE parts I needed to use). The fronts took 3 days!

What I don't want to do is give the impression that these are difficult to install. They are not. What was difficut for me (I'm no engineer) was determining what parts from the OE struts needed to be reused.

Now I know that, I could probably do the entire install in 3-4 hours (which includes taking off all of the stuff in the engine bay).

Taiwan.

It's actually made by this company http://www.bcec.com.tw/. The quality seems very high. Just remember: just because something is made in Taiwan doesn't mean it can't have good quality control.

They also allegedly make A'pexi's stuff, too.

I tried D2 brand (taiwan brand) on my Honda Jazz. but i do not recommended for you guys to use it (for street or circuit use). first, it's very stiff for street use,the shock absorber very hard even after I put it to soft, but it's too soft for track use. 2nd, tried to use it for practice on the track probably 4 or 5 times. shock absorber starts leaking.

so I decided to buy Japanese brand (J's Racing) the shock absorber made by CRUX Engineering, it's the best coilover kit i ever tried. I use it for Practice and Race for the past 2 years, and still in good condition until now (never been overhauled).

after you tried this kit can you give me the review. because after what's happen, I never trust any taiwanese product. but I heard megan in this forum a lot, so I'm just wondering "is it a very good product or just their low price?"

thanks
