ooo I like the idea of a diff cooler.

Captain Insano · 09-04-2013, 09:37 PM

Nice piece. I like.

TouchMyHonda · 09-04-2013, 10:05 PM

So becides cooling properties, whats the benefit? I haven't read anything or seen any issues with the oem diff. I dont ask to hate, I ask because I really want to know why you designed this and i dont get it.

"I know some of the Japanese race teams had some trouble with overheating the rear diff early on."

That IS the purpose, to keep the diff oil cool.

Captain Insano · 09-04-2013, 10:52 PM

I wonder about lower weight as well (maybe a couple pounds?). As is aluminum versus OEM steel. That would just be an added side benefit as main focus is cooler diff.

It also holds more diff oil so it's a triple benefit, more thermal capacity and lubrication from the extra fluid, and more dissipation from the aluminum cover with extra surface area.

That's one nice looking piece

Looks awesome, but road clearance is my concern... I'm too low

I'm pretty sure the stock Diff cover is aluminum.

It doesn't seem to hang that low. I'm only lowered 1 inch. It looks so gnarly. I like it. Price is good. The Cusco unit is twice the cost

I ran a 10 bolt diff in my old camaro.. I added an aftermarket cover with braces to strengthen the diff.. And it made a difference! But that was with a lot more TQ and some drag radials.. While the diff in this car won't see that kind of TQ.. I do like the added fluid capacity and possibly more cooling.. Also looks great from the rear... Very nice..

Foobar · 09-05-2013, 10:05 AM

Solid craftmanship! I'm not a fan of the hanging fins though. Have they proven to make much difference in temperature? I wonder if fins along the back panel coupled with a ram scoop from the bottom would work better - more surface area, and the fins are no longer hanging down. Won't be as gnarly looking for those who want that though.

I saw it in person yesterday, it's gorgeous, seriously pure art work...super phat daddies!!! Anyone changing out their FD Must also get this, it's a no brainer.

The factory cover is aluminum and is very light.

The purpose of our cover is to provide increased cooling, through

Larger fluid capacity
Better heat dissipation
Ability to install an auxiliary cooler

I had the pleasure of seeing this in person. It's gone through several iterations. Mach V doesn't release a home-grown part unless it's perfect. Diff heat is a good way to kill that 4-figure fancy diff you had shipped overseas

+50% capacity and cooling fins, with temp and cooler add-ons is a big win

This is mild-drop safe. My first thought driving behind the Mach V BRZ was "That diff looks low...." After some spirited backroads driving with plenty of bumps, can attest it doesn't hit. I'd feel comfortable running one on my daily commute.

Can't forget the bonus of supporting a US company and not paying Cusco tax on a part too
