= M7 Japan Coilovers =
Hey guys,
I recently purchased a set of M7 Japan coilovers for my 2008 sedan. I was previously on H&R sport springs paired with Tokico hp struts for a while. My previous set up was decent for daily driving but I wanted to drop my car tad bit more and have the damping adjustability so that I can firm up the damping/rebound. I always felt that my car was under-damped especially at high speeds or when cornering hard. As far as suspension mods, I have the following: M7 Japan Coilovers, Cusco Strut Bar, Hotchkis Sways, SPC Front Camber Arms, Eibach Rear Camber Arms w/ Toe Bolts.
I would like to thank Lou @ Amplified Motorsports for giving the opportunity to run these on my sedan. I know that these have not been officially released here in the States. I am actually the second person here in the States to run these on a V36 other than Lou himself. I know some of you guys are wondering about M7 Japan but they are not as widely known as other JDM company here in the States. However, they are growing fast especially in the circuit scene. They make many aftermarket parts for many imports including R35 GTR, and now the Z34/V36. Amplified Motorsports is an exclusive authorized dealer for their stuff, so hit up Lou if anyone is interested.

Anyway, on to my review. I've had these installed about 3 weeks ago. First, the build quality on these are rock solid. I can tell that these were manufactured with performance and quality in mind. The damping controls have a 35 way adjustability which is unheard of. I have mine set at 18 clicks up front and 16 clicks in the rear. I've dialed in about 700-800 miles since the install. I used to tell myself, 'why do I need coilovers when I will most likely never track my car? When my car is just a daily driver to commute back and forth from work?' I always told myself that it's an over kill for someone who daily drives their car like myself. But let me tell you, I was SO wrong! The difference you feel with a set of quality coilovers is beyond night and day. The car felt so much more planted overall in all road conditions. It really changed the dynamics of my whole suspension feel and how it handles. The biggest difference was the way it corners at high speeds. I used to feel my car to lack so much lateral traction when cornering at high speeds. I honestly thought maybe it was the soft sidewall of my Hankook V12's but it definitely was not the tires. After the coilover install, I can literally hit any corner and on ramp at nearly twice the speed I was pushing my car with my previous set up. The car feels so much more in control and predictable. It really feels like your on rails without all the understeering. If I had to rate the difference in performance in numbers, I would have to say it's about 3 times better than how my car felt before. I know that coilovers aren't cheap but this was one of the best investments I've made for the long haul.
Unfortunately when you gain something, you usually have to lose something in return. After the coilover install, I have to admit you give up some ride quality. Your ride will be noticeably more harsh. You will feel every bump and imperfection on the road which you didn't feel before. I personally do not mind sacrificing a lil comfort for better performance. My theory is that you gotta give a little in order to gain something especially when modifying cars.
So overall, I am very happy with my decision on the M7 coilovers. I know that these are not cheap but IMO it's definitely worth the investment if you want to explore the world of fine tuning with your suspension. I still have to do some final adjusting before my final alignment. I will hitting up Lou again at Amplified. All the guys there are super friendly and will treat your car like it is one of their own. I will follow up this thread again once I do some final tuning with my suspension.
Here's the pic after the initial install. I am lowering the front another .5 inch soon. I will definitely get some proper photos once everything is finished and dialed in.

What made you go with the M7 (something that clearly hasn't been around the block) versus one of the others mentioned on these forums like KW3, Tanabe, stance, ark, bc, megan...etc?
Not trying to question you or your choice, but I'm just wondering if there was some specific reason like cost, or performance on another vehicle.....

No love for AWD yet since these were made for the Z34/370z's.

whats the price range on these things? are custom rates available? does it come with matched shock valving? are swift springs available because lets face it, they appear to be better than run of the mill coilovers for sure but the springs are not swift springs, nor can anyone argue that point.

Great write up OP. Thank you for your honest feedback.
I have the coils on my G and I'm quite impressed with them. I'll go into more depth details once I get a chance to test them some more. We just installed another set on a 370z and he tested them on at button willow yesterday and was very pleased with the results. With the m7 coilovers and whiteline away bars, he shaved almost 4 seconds from his last visit at button willow
KevMo, yes we moved. Please see my Sig
Sorry no AWD for now but I'm trying to convince them to make it
Swift will be an option very soon. Working on something to make to change the rear bottom spring seat to fit Swift 2.5 inch OUTSIDE diameter springs

Glad you're happy, man. Good stuff.

Come on... Relax.
I'm not talking about popularity. I'm saying that ARK and Stance are hardly "tried and true" and have not even approached the block let alone been around it. This is what is dangerous about forums. People develop their false beliefs based on false information. Someone would read your post and then repeat it and repeat it again and someone else might repeat it, etc...
ARK introduced their coilovers less than a year and a half ago. I think I have seen one G with them installed. That is all I was saying. They are hardly "tried and true." Please don't tell me to "slow my roll," whatever that means. Maybe you should just think twice before you post something that can easily be misconstrued by a member who knows no better.
