anyone have any experience with a gearset like this?

MGR-G975390

made from a different alloy, supposed to be stronger than the "normal" sister set. just curious. i bought them and plan on having them professionally installed soon. install will be as good as it gets, this guy has done 2 other installs for me and numerous others for locals.

That's the orange box. They're noisy. Look at the holy whino thread a couple under this one.

I see now, I wasn't familiar with the G9 prefix gears. They seem like Motive just released these.

Just curious, I've been wanting to go with 3.90's but have been putting it off because of the orange box noise and they dont make 3.90s in the blue.... Are these supposed to be quieter than the orange box? I also see they are almost twice the price of the orange box..

Edit: just looked on their website and evidently G8 is fro the street and the G9 designation is for competition use only. So maybe its a soft compound not meant for repeated use on the street? I guess the orange box are still the only way to go for 3.90s

I've done a bit of research already on the 9310 alloy. was curious if anyone here has tried these gears on a non dd type car that might see 1k miles a year. basically these are stronger by nature but not heat treated like a street gear. the 9310 is like a memory alloy and will flex instead of break then return to its original shape due to its inherent properties and high nickel content. downside is faster wear. if anything I'd guess they're quieter due to being "softer". say they wear 3x faster. that's still what like 60k of use? say it's 50. like this car will see that many miles prob the rest of its life.

I'm going to try them. someone's gotta be a guinea pig. and if this means I can dig on the street without worrying about the ring gear spitting teeth that's good right. we shall see. I'm trying to catch up on heat and generation in a differential before going crazy.

the gears are in. so far they are very quiet. but it is hard to hear much with an fm10 on the car. I have about 100 miles on them. I def like the 390s better than the 410s I had in a previous m6 fbod.

good to hear man, i'm really wanting a set of 3.90's i'll probably just go orange box, get a solid pinion spacer and take my sweet *** time setting them up

I just got hpt as well. I foresee many 4th gear pulls in this cars future. well see how the gears hold up. since they are "race only" gears I presume there is no breakin period. I'm going to change the fluid after 500 miles anyhow.

excuse my ignorance, but what is an fm10?

When yopu say "very quiet" do you mean no noise like OEM gears or "just a little whine" ?

flow master single chamber muffler.

there is barely noticeable whine from like 30-40 after that I can no longer hear it. I can hear the trans over the gears lol

got about 1500 miles on the gears. nothing abnormal thus far. i'm going to change the fluid soon so i'll take pictures and whatnot. done a lot of 3rd/4th gear pulls. no digs as it will spin tires off the hit in 3rd as it is.
