New to Mugen
Hello. Like the title states I'm new to the mugen seiki mbx8r eco. I switched from a tekno eb48 2.1. I've had the chance to run the mugen for one race day. Wasn't good due to wrong tire choice. How is the kit setup for a large medium grip track? I've read somewhere that the kit swaybars are alittle thick and should be running thinner ones. Any help or advice would be greatly appreciated. Thanks

Usually every 2-3 years. The mbx7 was around for 3 years. The mbx7r for 2 years. I think the mbx8 was also on the market for 4 years, but we had covid in between so that might had an impact.

LW arms????
What are the purpose of the LW arms for the mbx8r eco? Besides lighter weight would they be a good tuning option for a low/med grip track? Reason I ask is because the rear end of my buggy breaks free everytime I get on the gas after I make a tight turn like a 180 turn and causes me to oversteer and hit the pipe.

I pretty much have my T set for the indoor track due to the season I raced last(carbon inserts)...haven't reset for summer....I have enough og6T arms to really give it a solid chance outdoors, May just run no inserts first in the 6T, then switch. My 8 buggy is so weird in a good way...its awesome for me personally...and its hard to give up on it and go back to what feels like gens-old design(I know its more nuanced than my generalization about it)..may pull inserts out of it too. .
On a different note.....I've recently considered running a much lighter center diff than would ever run normally. (Thanks JQ invisible speed series for that) to try to tame the snap oversteer on hard in, hard out tight corners.
I've also kinda embraced how my stuff drives, how I can drive it, and just adopt my race craft around it, tactically speaking.
After proofreading, I may have taken for granted you know 6 and 7 arms are similar to the new lightweight 8 arms. Also, I have zero experience with the new arms. My opinion is based solely on the structural similarities of the arms design to gens-old.
And, on a side note question.....can I ask?
Wouldn't slightly "heavier" arms maintain a lower COG? Or on a micro level, since they are sprung weight, cause instability on rough surfaces?

If they continue the same upgrade trajectory..The new R's are the last "iteration" of the 8 series. Can't say how long till the 9, don't know if anyone can.. The 8R is what I'd get if I were you, and didn't wanna wait for an indeterminate amount of time.

does anyone know if you can fit the MBX8R battery tray on the non "R" MBX8?

Picked up a very lightly used 8R eco a few weeks ago and ran it the first time this weekend. The track is temporary and built the night before the race at a fall festival fair type of thing. The track tends to be pretty loose with lots of dust and loam, but they do their best to pack it down tightly the night before. For an idea on how loose can be I was running X4 bowtie 2.0's and that was just because I didn't have any super soft Enduros.
I tore the car apart last week and basically put it back to kit setup other than a few Drake changes. I also ran a standard size pack because I don't currently have a shorty 4S and I didn't want to run a jumper with two 2S's. The car squared up excellently, and the shock package was spot on. I wouldn't even say it was aggressively loose coming out of the corners. There was one big table top on the back straight, and then two ski jumps in a row on the front straight. Most of us learned early that it was faster to sky the first one and slam into the face of the second one then rolling the first one and jumping the second one. The shock package would consistently take that flat landing beautifully lap after lap.
The only other real obstacle was a small 5 pack that my car was easily able to double triple or triple double. Coming from an associated B3e that just never seemed to work right this thing was absolutely awesome. Was able to take the TQ in the second round and drive away in the a main to a win. While yes it was a charity race, there were something like 50 e buggies, and four or five sponsored drivers in the a main. Definitely excited to get this thing out to my local track and see how it does on something more normal.
P.s. Damn Proline tires kept coming unglued all day. Finished the last minute or so of a main with the foam sitting there on the arm.

Looking into getting a Mbx8r Eco but on the fence, so many buggies to choose from, , Would LuV honest opinions if you came from another brand which brand, wear, Pros an cons, performance box stock exception of diff or shock oil changes, any and all info to help me along with my choice.

The vast majority of successful cars out there, winning every weekend, are Mugen copies, or Mugens. Its pays to go with the original.
The only thing Id like to see, is more adjustability. Like the Xray. But that adds cost. And costly option parts, like Xray.
I loved how my obsolete Mugen Eco handeled on the ground. But hated the shocks and suspension travel (or lack of). Pretty sure they've fixed all of that.
Easy brick pack layout. Easy wiring. Even a center diff cover to protect the wires.

Just ordered my mbx8r eco, curious what diff fluids people are starting off with, 5/5/2 like manual ?. I saw the Adam Drake build where he said he uses 10 10-7 but in his diff fluid videos he said that's with universals, with the CVA he runs 5/7/4. Tracks I'll be running on are usually going to be hard packed medium to high bite outdoor clay.

Then 10-10-5. Then 10-15-5.

Cool. AE just won 2 World titles, with a Mugen. Xray in 2nd in one of those races......with a Mugen. Ryan M in 3rd, both of those races, with an actual Mugen.
And Mugen/Xray/AE have been on every podium I've seen, for years. Dont just look at a couple World/Nat events.
That's just my perspective. Mugen is the benchmark right now. (I'm running the Xray version)
