Who or where is the go to for Mugen parts ? Not much available yet for the MTC3 .
Can you even order from the Mugen website ?
Thnx in advance.

Mugen Seiki USA California has pretty much everything as far as I know under Shop > MTC3, A Main Hobbies will likely follow soon.

We had every part in stock for the MC3 when it came out. We are waiting on a restock now but still have several cars and lots of parts in stock.

All I have read now are descriptions of bent chassis due to serious accidents (frontal or at high speed).

I have also seen normal 2mm carbon and aluminum chassis bolts stripped or bent. And that with impacts that didn't look bad. You often cannot visually assess the force of an accident (direction etc.)
The plates on the chassis (A2173F & A2173R) that lie under the wishbones probably have the exact purpose of preventing this. They distribute the load of an impact over 2 bolt holes instead of just one.

It should be no problem for third party suppliers to simply produce a 2mm thick carbon/aluminium chassis. Then you can also remove these connecting plates. Motor mount, bulkheads and even the servo mount are pinned anyway. It's not a problem than can't be solved pretty easily.

I'm not worried about the stock chassis. We just got our kits in this week and I'm starting to build one for myself. The chassis has some decent amount of flex in it, just make sure you don't forget to install the top deck screws when making changes. I did that at 180 Raceway last year with my MTC2R FWD and it wasn't pretty when I slammed the wall at the end of the straight going into the sweeper...LOL :lol:

We have kits in stock as well as just about every part, option part and special tools.

Debris on the track!

But Ive done it with my AMX before and no its not a good thing!!

A2447 bumper
 
Has anyone purchased this bumper yet ? A2447 ? Only place I found it for sale was on eBay and that appears to be a bogus shop .

I ordered a couple from here... https://www.rcmarket.com.hk/index.ph...earch=MU-A2447

If you have a 3D printer, or know someone with a 3D printer, just print one yourself for free

Thanks!

Can we talk more about this active/fixed upper shock link? How does it operate? And with what impacts? How are you all using it to reduce lap times?

Antimullet 07-24-2025 08:13 AM

Just my theory, since the active is recommended in the rear, I think it helps artificially reduce rebound dampening and keep the tire in contact with the ground.
I could be way off base though. Interested in hearing what it actually does.

archivist 07-24-2025 08:57 AM

It's an interesting tuning option, though it sometimes makes me think manufacturers are just going too far. ha. But for now, let's assume this feature can help us drop tenths.

I agree with your theory, Antimullet. The shock has been shortened, but we have the potential for greater suspension travel, however floppy.

I initially set the mtc3 up with the box asphalt configuration and given the ride height (shock collar) and down stop settings, i didn't see room enough for the active suspension to even kick in--the shock presses the upper mount against the bulkhead (ie, the fixed position), and the downstop setting would prevent the arm from moving low enough to allow the upper mount to move.

So, I have some experimentation to do here just to see how to get this thing to kick in.

Ive always thought of it as a way to allow the inside tire to Droop faster, keeping in contact with the surface.
Your not waiting for the piston to travel to shock oil.

My only concern/question was how does it feel or react when the corner drops back onto it.
Probably something the bigger tracks benefit from but smaller more technical tracks probably dont use much.

bmwjoon 07-24-2025 09:45 AM

The active shock towers have been around a while. Makes the car more driveable by helping keep the inside rear tire maintain more contact with the ground during a high frequency event, like curbing or bumps. I've seen cars run it in the front very infrequently. Most if not all drivers use it in the rear. You don't really sacrifice your normal setup or balance but improves stability. You just have to know what you want to do and how to properly set up your droop because now it decouples shock length from your droop limiter.

You notice is high speed chicanes. Like others have mentioned, it allows the inside tire to drop much quicker instead of relying on the rebound of the shock and rollbar. I've used the active towers also to help if mellow out the dips the track may have like you would find on a parking out track.
