This thread is misleading. I thought these mounts came with shiny new hardware...they do not. Can anybody help me with what size bolts I need? Also why did you guys weld a flat washer on your tab? Mine does not have that.

I cnc'ed these myself over the weekend.

As an update to using these mounts for several years now, the entire time making 700+AWHP, and with the Front line Fabrication billet rear diff cover and billet main caps I have had zero issues with the rear end. For a while I still used my original rear diff housing and ring/pinion/diff with the front line fab cover and stock main caps and finally killed that one (evo diff side cover elongated the bearing bore and walked the bearing, resulting in killing the original ring and pinion with 12 years of abuse from me back in 2013). I also changed the evo clutch type rear diff side cover to a chromoly steel one made up for me by Jon @ TRE (Ninja cover).

Boston's product has held up 100% and everything has been all good in the neighborhood!

[bostonhatcher]

I've been working on a good, lightweight solution to mounting the 2g rear differential into the 3-mount subframe for the past few months. What I've noticed, is that the differential likes to rotate around the passenger side bolt that's on the front mount. The driveshaft gives the differential a torsional force like a helicopter, resulting in breaking the far left diff cover bolt (force x radius). Of course some are even breaking both diff cover bolts, because once the left lets go the right side bolt has twice as much load to hold onto. Well now the days are over where you take the entire rear end of your car and you can have 4 solid mounts just like the 1g's and evo's.

The mounts are 6061 billet aluminum and weigh 1.2 lbs a piece (stock weighs 2.4 lbs). The third piece is 1/2" thick, water jet cut steel. I had to drop the subframe to weld it on because it's too close to the gas tank. I was able to lift the entire subframe with all the suspension parts on it by just the mounting plate.

I like your design, If i had a 2g i would use this, What are you selling it for$$

 

[yoscoobie]

Have you sold any yet??

 

[TrevoREX]

These look incredible. Are you doing individual orders or full group runs? I'm doing an awd swap so everything is all apart making these super convenient and "cheap" insurance. If you don't like/want to talk shop "on-thread" shoot me a pm.

 

[T2Small]

You might have trouble finding the rear diff on a FWD.

 

[Phudu2004]

I'd be interested in a set as well.

 

[bostonhatcher]

I just got a new batch in and they look terrific!

 

[Jerzm3]

Im interested in a set. Please pm me the info or email me. [email protected]

 

[ilikejesus]

I will definetly have to look into doing something like this

 

[steve-o_95_GST]

I have been waiting for these! Do you have an idea of when you will put them on sale?

 

[MindBlowin03]

I got my set yesterday and they look great. Hopefully in the next month or two I'll be installing them.

 

[91talonts1]

I've had these on my car for around 2 years now. They've seen dozens of hard launches on the street and track and are holding up great, no problems whatsoever. Great product.

 

[bostonhatcher]

Thanks guys!

 

[bostonhatcher]

Has anyone broken a diff cover with these mounts installed?

 

[MindBlowin03]

Since this came back up here are a few pics of my install. So far so good as far as function goes. 600+ awhp but only about 100 miles on it so far.
