Well this is for all you guys that have wanted new rear diff mounts/bushings. Well we took it a step further and are making and entire new bracket out of aluminum with a stainless sleeve where the brackets mount to the body.
Here is one of the brackets done up in Solidworks.

this is the type of product development this platform needs.

So I've been thinking since we are making all new brackets would anyone be interested in having an option made for running 1 piece driveshafts which would correct the pinion angle?
If so would anyone close be willing to lend their DS for R&D?
how much for this bracket?

That is cool! Any idea of pricing?
anyone weighed the stock piece?

Well I'm guessing there might be a slight weight saving but this is mainly to keep the diff from moving

I'd definitely be interested in buying something like this. I'm not close though or I could lend you a PST 5-speed 1-piece driveshaft. Lol.

Do you have photo360 with your solidworks software? I would render out your part with it! very cool! I also use SW for all my design work! Great job!

how many people are you gonna need,im down for a set
Seattle:
Good to see you back at work Seattle :)
MeTarzan:
so can I ask for a weight comparison between yours and the OEM yet?
how is the diff moving as little as much as it may at the moment a problem? I assume this bracket would be able to take some sort of noise dampening?

Seattle??? are you on crack Mike?
Seattle is the guy that made the mad mounts :)

MeTarzan is not Seattle................ Seattle does make the solid and poly mounts and bearing loaded shifter but this ain't him.

LOL..... Carry on now.
Back on topic. Will these cause much vibration? MR2 has a supercar [correct me if I'm wrong] rear diff that is already very noisy. I could imagine with these and his diff it would vibrate badly and be rather noisy.
Supercar sold it, it's a Kaaz, it is quiet 98% of the time...just very low speed moves with the grabby clutch has it clacking a bit, the reason I'm asking is a good friend of mine who own's a RX7 (FC), he went through the whole sh-t fight to put solids in, then could not believe it and went poly's....about another 10km of driving and he went back to rubber...
now don't get me wrong I'm keen...but no way am I going to deal with how crazy noisy his diff ended up.
what I WILL pay good money for is OEM performance, light weight aluminium stuff, my theory is the whole car is solid steel, you should be able to swap a large amount of those parts for Alu stuff that performs the same and have a 50% saving in weight

Well since the stock ones only weigh in at 3lbs combined its gonna be hard to make them much lighter. We only have them designed as solid right now but there are always possibilities if there are people wanting them with poly bushings

Would only be interested in a poly option

not hijacking this or selling, just showing what I did for MY car :)
That is a lot lighter than what I remember my Diff mount being.. maybe I'm mixing my cars up :|

the side mount pieces are tiny.
Every time a RACE part comes out we see a handful of guys wondering if it is going to be as comfortable as stock.
Obviously if you solid mount a differential to the car it is going to transmit NVH to the chassis. The point is to reduce the axle movement for better control of the axle angles, thereby limiting wheel hop and possible axle damage.

you mean I cant have racecar and have it ride like a caddy?? LOL
ok maybe we're talking about different parts.... the part I'm talking about is this:
http://3000gt.com.au/car/Misc/diff/DSC02180.JPG
it weigh's an amazing amount
the point I'm making about having a rubber bushing is with the solid part my friend car was undrivable for more than 5 minutes without doing your head in.
do we have a video anywhere of something driving around with solid rear diff mounts to see how bad it can get?

right, you are talking about the wrong part.
This is for the brackets on each side that are near the pinion.
This type of part is for a race car. Not for taking your whiny girl out on a date, not for going to the mall, not for transcontinental journeys. This is meant to do one thing and that is keep the diff in one place.
No one is going to be able shoot a video for you of a part that doesn't exist yet.
I don't even like poly motor mounts, so this is not for me. If I was serious about getting the car down a track I would buy one.
if you say so, why would you swap the front braces and not the rear one then?
since when were people buying Race only parts, most of what you see actually selling on these forums are parts that are dual purpose.

Jesus if you can't wrap your head around a SOLID BUSHING being more for race than street and then want to sit here and argue that it won't be comfortable on the street I give up.
