More important???

synolimit

What do you guys think is more important? Rear brake duct cooling or diff cooling? Right now my hoses are just tied up and they were going to go to the brakes but I just don't recall many track cars cooling them. Also stop me if I'm wrong but since we already have bad ice mode would I want the rears to stay cool and lock up better or let them over heat and slip? The diff cooler already works as you can see the mounting plate bends down directing air up into the cooler but I'm sure more doesn't hurt. I'm also thinking of taping into the drivers side hose and Tee off a line for the back of my neck during hot track days. What would you do?

Hoses are 2.5" so plenty big, hell the front only fit 2" an their more important!

I would definitely go brake duct cooling over diff, considereing these are the rear though and only doing about 35-40% of the overall braking... I might just opt out for diff cooling here. Nice set up

I would :

1. Get rid of that hideous exhaust
2. Measure diff temps and add ducting if needed
3. Measure rear brake temps and see if cooling is even needed

I wouldn't think the rear brakes get too hot unless using slicks or running long sessions.

Ummmm by far diff cooling. From seeing what our diff temps run with our cooler/pump/ fan setup.... Your diff temps are well over 300 F... Even in a 20 minute session.

1. frankenstein? Hell no! Beauty under a track car isnt necessary.

2. Diff temps fluctuate a ton. Just depends what you do and how you move it so it'll be hard unless its track day after track day.

3. Ill get a laser pointer temp sensor then.

Slicks maybe, sessions 20min or so.
