Mugen Seiki MBX6 M-Spec 1/8 Off-Road Competition Race Roller Buggy (w/Wheels, Tires & Stickers)

I have been going through this pre built M-Spec and wow, there must be some strict quality control going on over at Mugen. Everything was absolutely perfect, well almost....

I did take apart the front diff and it was not filled properly, so now I have to check all 3 diffs, not a big deal though as not a screw was stripped out, or anything loose. I did need to put thread lock on everything, the stuff they use is too soft and will not hold up under race conditions, but for a pre built buggy it was the best I've seen yet, the outdrives were greased during assembly, big plus, that means I can just open them up and add oil, not tear the whole darn thing apart nice addition Mugen.

Oh yeah the shocks were perfectly built too.

The ring gears need grease, they were bone dry when I went to shim the gears. I put one on each side of the diff on the front, and one on the gear side in the rear. Most likely because everyone like their own special grease, just remember to take the diffs out to grease them and shim them properly. The only aftermarket part I thought the buggy needed was better diff o-rings, after trying several futile attempts, I found Tony's O-rings and they fit perfectly. No leaks, not an issue anymore.

Go ahead and use longer screws on the bottom of the radio box, not under the servos, but going into the radio box, and also on the fuel tank mounts where they mount to the chassis, those screws are begging to strip so add 3mm to the length and forgetaboutit....

The front shocks could use the optional black pistons to keep the front off the ground, and keep 45wt oil in them or 40wt, and add the 9.5 t springs because the stock front springs are a bit too soft.

The rear shocks are perfect....The best I've seen in any buggy. Plush travel, and lots of it.....

I never thought I'd see the day I could get a Mugen that's built in the box and with actual race tires in the box premounted.

It truly is the glory days of 1/8th scale buggy racing. I felt spoiled opening the box and realizing OMG I don't have to thread those turnbuckles and trim flashing, the screws already cut the threads, the bearings are the best sealed bearings I've ever seen, The cvd Pins wear really slowly, and the outdrives are long lasting too.

The materials are great, and the on track performance is great if you learn how to tune it just a bit to get it dialed. The M-Spec setup is great for learning the car, and how to drive it. After that you can tighten up the low speed steering and it will deliver the goods in the A-Main...

My most favorite thing about the Mugen is it just flies over jumps and tough sections of the track when timing is needed to make a jump, it does it.... It lands without issue thanks to the perfect shocks, plush travel, and years of Mugen evolution on suspension geometry...I've pulled wheelies in battle, landed huge jumps in the flat, and cut the turns as sharp as I like. I've given this buggy the last half of 2010, and it runs hard, rarely needs adjustment, and can go several races before it needs to be rebuilt, However, realize it does need to be cleaned eventually, so take the time to tear the whole car down after 10 full race days......and replace bearings and so on...

And don't be afraid to make some changes in the car. The M-Spec setup is good, but you can make it faster over time....try a 14t clutchbell on a bigger track, this buggy loves Horsepower. It somehow keeps up with a fast engine....It feels planted on the track, and will allow fast drivers to push it harder, or keep the beginner on all 4 wheels....With the great high speed steering, you can increase the low speeed steering and have all the steering you need while keeping the back of the car in line, a rare quality in a car I must say....



Get er freakin Done Mugen.......

the best buggy out right now IMO. Very fast, very durable and endless tuning options. GREAT A++++++++++

this car just keeps getting better every time i drive it its got about 4 or 5 gallons on it now and is still as tight as the day i bought it no slop nothing wore out . this is the highist quality car you can get at this moment. the xray is quality to but its just not stable in the rough stuff and it has to much plastic on it for my liking if your looking for a new buggy this is the 1 to try there is a lot of guys at my track switching to the mbx6 this year because they drove mine 1 time ITS A GREAT CAR just get it and leave reviews of what you think about it -//- just plain awesome does everything great dont beleave theres a better buggy out there at this time and the m spec is built better than most people can build them there selves just buy it and thank me later you will love it everbody that does own it loves it the best of the best in my opinion. while everybody else is breaking the mugen will still be going its that tough -//- its a great car more steering than anyother car ive drove jumpes great its built great and of high quality i am sticking with mugen from now on. I came from a hyper 9 it was a good car but had bearing problems along with others then went to the odonnells and just didnt fit my driving style. but the mugen just feels right to me

This car has everything you need to be competitive! The mbx6 is a great way for anyone to start off racing, it jumps incredibly well, has more steering than just about any car out there and is very responsive to setup changes! The only issue i have ever had with this car is breaking lower front arms, particularly the left one (looking from the back of the car). This hardly ever happens but i feel like its the only thing i can think of when i have broken anything. If you decide to buy the mspec, do yourself a favor and go through the car! Mugen does a great job putting the car together overall but still fails to put enough grease or any at all where its needed and many of the screws that need thread lock do not have any.

Make sure to buy a set of the proteck/tony screws diff o rings! This will insure your diffs stay nice and full and not mention just keeps your car cleaner around the out drives.

Only other thing i can think of is that if you want the latest option parts (5mm longer chassis, all the new springs) you are looking at about another 160 dollars. I only mention these because i would say the majority of racers are currently running them! You also have the option of just buying the springs you want, i just felt that is was better to buy the whole set.

Awesome car out handles most buggies with no problems. Very tough and durable, definently a good car for the price. I will recommend mugen products to anyone.

Awsome buggy!!! The best buggy I have driven, went from the rc8b to this and the ae is shit compared to this one, my lap times went up a full second a lap. No problems with the build quality of mine what so ever. Would recomend this to enyone.

This buggy has proved itself time after time. The quality is just great and it drives as good as it looks. Pro racers use it for a reason!

It is great refine buggy that has lighten with better weight distribution; however, it is not stable on the rough section at the track because of shorten wheelbase. I was awe how fast on the corner speed and handle the jumps easily without any stress than previous 8ight 2.0. Thus, I set up the shock tower position more outward to keep MBX6 more stable and changed thinner sway bars to respond quicker on corner and rough section without losing control, also with a help to move the rear hubs for increase wheelbase. This gives the best handle all round sections on the track. Needless to say This M Spec is not suitable for my driving style but I do make some changes on the setup with pre-load and dial up. Now it is fixed my problems! It gives me joy ride on every club races.

AWESOME!!! I absolutely love this buggy. Went from a 1.0 losi 8ight to this. Man, I wish I wouldn't have waited so long. You will need to go over the screws/nuts. All were snug, but not as tight as they should have been. TOP NOTCH BUGGY!!

Hope this buggy starts a new era!!! It's a super buggy!! And it has that toughness that others don't have. The setup is perfect for me. Just put in your electronics and engine/pipe and your set!!!

I ORDERED THIS BUT I WAS SHOCKED TO FIND OUT THAT I DIDNT GET ANY WHEELS, TYRES, UPGRADE STICKERS, AND WORSE , I AM MISSING A SINGLE NUT!

I HOPE FOR A RESOLUTION ON THIS.

I had both my rear shocks leaking in the box. I saw that the shock baldder was not properly assembled. There was some plastic peice sticking to it and hence the leak. Bad quality control.
