In the rear, do you have to take out the bottom bolt and spin the lower half up (to lower) and down to increase height?

Same for the front as well, you need to unbolt the bottom bolt and spin the bottom of the coilover body?

Using the spanner wrenches you loosen each perch away from each other and move the top to the position you want and tighten back together. Very easy to use!

Keep in mind, if I decide that the dampening is not good enough for my likings I will just buy another set and sell these cheap!

I have found the noise in the rear to be the hard foam in the bumper flopping around. I have insulated it with more foam and the noise is gone!
The front sway bar bushing seems to make a squeak noise with ambient temps lower then freezing. I've made sure to lube accorddingly but it still happens. 40 degrees and up equals zero noise...weird!

As for the coilovers, zero problems. I've turned the rears almost to complete soft to help with the sharp bouncy feel. Still feel the price is worth it!!!!!!!!!

G35guy84 01-15-2010 03:10 PM

Hey Kev,

Do you have any pics of the inside of your trunk or wherever the rear dampening knobs are? The reason I ask is because mine are on top of the coilovers and the shop that installed mine cut small holes in the plastic covering the rear towers so I could have easy access to the knobs. At first, I didn't think anything of it, but now it's starting to bother me that they cut holes in my car. As soon as I get pics of the install, I will be sure to post them.

Hopefully you have better luck than that guy.

Sorry, I still won't run taiwan junk. For the guy that said that BC is the one making the coilovers for APEXi and Greddy: He is dead wrong, even if he is correct. When was the last time a greddy or APEXi coilover detonated?

What do you expect would happen when you hit a pothole?

I agree! Any coil-over will break when hitting something (narrow assembly).
I broke a set of APEX coil-overs 4 cars ago hitting a curb at 60 mph. (don't ask) :rolleyes:

G35guy84 01-19-2010 06:29 PM

Where is Kevin? I'm eagerly awaiting a response! :D

jmlenz 01-20-2010 12:17 AM

I just picked up a set of these coilovers and should have them installed in a few weeks. I was sure to get the newer side adjustable dampers so I didnt have to worry about the rear access. I will post up a review with plenty of pics when its all setup.

Sorry Eric, I missed your post! I got the most recent version which has the adjustment on the side of the shaft. I just have to jack the car up a bit and reach under the fender to adjust!

What's the highest/lowest I could go with these? Since I have the F.I. Exhaust, I can't go too low, otherwise I will hit my mufflers, if I want could I set it to about 0.7" lower then stock? Is it easy to adjust? I ask cus I never have had to deal with an aftermarket coilover kit.

jmlenz 01-21-2010 03:47 PM

^ Jon I should be able to help you out with an answer in a couple weeks. I have the coilovers on order and am getting the FI CBE installed on the 29th. I plan on going about 1.25-1.50" lower than stock depending on fitment/clearance. I will take some measurements from the exhaust to the gound when the coilovers are installed for you.

Hi again everyone. I have been to busy to follow the forums.

I have 7,000 miles on my Megan coilovers and haven't had any problems. I've done a few road trips and had to adjust the shocks to softer settings because when I have them at 9 from firmest, it is too harsh for long trips and gives me a headache. Overall, They are great. the spring rates and dampening are pretty much perfect.

The only problems I have with the setup are 1) the rear springs at the highest setting still lower my car by 1.25 inches and 2) nissan didn't design the car to go that low. By the time you get the car low enough that the tire is into the fender well, but still able to see the tire tread, it scrapes on everything.

so on issue #1, I had to match my fronts at 1.25" lower than stock. The fronts can go higher than that, but not the rears. The car looks great at this height, but it scrapes on everything and I would like to go higher. The front cradle and underbody skid panel touch down on hard bumps. On the I405 in San Fernando valley the concrete slab pavement has terrible expansion joints and some of them will cause the cradle to touch down at 70mph. My Stillen exhaust tips touch down on the inclined driveway at my work, so I rarely drive it to work. I would much rather be 1.00" lower than stock.

on issue #2, it ties into issue 1..... Megan needed to make the rears so they will go higher, but Nissan didn't design the fender position quite right. By the time the car has the sporty appearance of the tires just tucked into the fender wells, everything on the car is touching down on the pavement: front cradle on big bumps/potholes, underbody exhaust on the smallest of speedbumps, exhaust tips on inclined driveways, front tires hit the fender liners under heavy cornering loads when you hit mid corner bumps. Its pretty messy. My last car was a C6 Corvette and the suspension is adjustable from the factory. At the lowest setting the tires were tucked into the fender well very nicely, but didn't hit the fender liner. The front airsplitter would scrape, but it is soft and designed to fold under without damage, as opposed to the riveted nisssan one that I've broken twice now. The Borla exhaust I had on the Corvette never touched the pavement. The exhaust under the car would only srcape on pretty good sized speed bumps.... The 370z just wasn't desinged to go low enough to go racing. The Corvette is.

azn370z 01-23-2010 07:03 PM

I'm curious how much ground clearance you have. When I measure near the tow hook thing, near the cats I have about 4 inch of ground clearance. I'm not lowered on meagen though. I've only been lowered for a week and have driven highway and driven over many speed bumps. I have about a finger gap all around, with the rears having a bit more.

Mike@Blackline 01-24-2010 02:12 AM

got a friend with a 240 on megans. he loves them and i enjoy riding in his car. i cant stand people who bash things because of price points

NewYorkJon34 01-24-2010 08:55 AM

It's not the price that's worrying me, it's just that the lowest I could go is about 0.7" because of my exhaust. Plus where I live in Florida, there's plenty of dips in the pavment so if I don't take it slow it usually hits that black plastic front piece. I guess the only option for me is the S-tune suspention, 0.4-0.5" drop.

I've had mine up to stock ride height but I think I some how got a newer
version.
Note: Drove to Savannah this weekend and the highway to Savannah sucks! I did not like how these coilovers handled the bad pavement. The dampening had me and my wife bouncing. She actually got motion sickness. I may sell these cheap just due to the stiffness & dampening. I feel it's more suited for a younger person...

jmlenz 01-24-2010 08:23 PM

Kev > your ride height looks pretty good to me and seems to eliminate the wheel gap, do you have all the clearance issues that Phimosis mentions?

If you sell them cheap, I'll buy them from you. So your saying I could lower the car to about 0.6" lower then stock if I wanted with these coilovers?

G35guy84 01-25-2010 08:36 AM

Does anyone else with these coilovers feel the car rock back and forth immediately upon stopping? Why does it do that?

Rocking is caused by spring bounce, which would indicate that you don't have enough damping dialed in. Turn up the dampers a couple of clicks. Do you know what number they are currently set to?

Yeah, I was at 16 at the time. Today, I dialed them all the way down to 1 (most firm) and the rocking went away somewhat, but it's still there. I just want to know if it's normal and I should stop being paranoid.:ugh::confused:

azn370z 01-25-2010 04:40 PM

It might be normal for Megan to rock back and forth but coilovers shouldn't do that.

G35guy84 01-25-2010 04:46 PM

^^ :wtf:

Does anyone else with coilovers wanna chime in?

azn370z 01-25-2010 05:06 PM

I have coilovers and mine don't rock back and forth. Mine has 30 levels of firmness and I set mine 10 from hard.

I do get rubbing up front on occasion over high speed dips and bridges.
may roll fenders a bit...undecided!

Usually if the coilovers are set to full stiff and there is no give so you get that sensation...generally means they need turning down. Try that and see...

I'll let you know! I still can go lower so yes!!

Just received coilovers AND my new wheels. Setting up install next week!

I changed the setting to a softer one (24) and the issue has essentially been resolved.

Glad turning down the stiffness worked! :tup:

jmlenz 02-04-2010 12:48 PM

coilovers are installed! First impressions are excellent:tup: I have the dampening turned full soft and it seems to ride very comparably to stock as far as firmness/harshness goes. To be honest, first impression of these 'budget' coilovers are more favorable than my Tein Flex coilovers that I had on my Z33. I'll do a full writeup after a week or two of driving so I can give a more thorough review. Stay tuned...

G35guy84 02-04-2010 06:20 PM

G35guy84 03-07-2010 02:53 PM

Finally, some pics of my Z with the coilovers installed with wheel spacers and Ichiba rear camber kit. Using my car as a daily driver and not intending to track it, I am still very impressed with my setup. Although, I don't have much clearance with the F.I. exhaust cans and the ground now. Sacrifices must be made. lol. :tup:

I actually don't know how much they dropped it to tell you the truth. lol. I should probably find out, huh? ;)

whoady4shoady 03-08-2010 05:35 PM

All this stuff with find the proper settings and spacers sounds complicated. LOL
