brake ducts

agree, have to run lines all the way to the rotors to make any impact. oem just throws air into the wheel well.

i am gathering the parts to make a custom brake duct install using 3" duct. will keep you all posted.

brake ducts

those brake ducts are incredible.
i am also running the comp dual oil cooler and looking to add REAL brake ducts, just bought all the parts for DIY


the one thing i keep asking is has anyone removed the spring and plunger from stock thermostat and tested on track to see if can keep temp lower, or does the ER dual saturate at 260 F regardless?

Brake ducts are awesome...when they look like this: that go to the back of the rotor/caliper. Brake ducts that shoot at your front tires are useless (factory stuff).

As for lower thermostats...it's a band aid fix. Street cars it's fine as typical use does not tax the system. However, when racing different story. Let's say your starting temp is 210 vs 230. It's still going to hit whatever peak heat temp you're going to reach as thermostats don't cool anything. Oil temps when at WOT climb really fast. 20degree starting temp is not gonna make a difference. Maybe 100-200 feet longer before you hit limp mode

track the car first, you'll see ER is just perfect. the extra water cooler is not needed if you run JB4 max cool mode - higher water pump and fan speed.

Iīm planing to upgrade my cooling system as well cause Iīm not able to do prolonged highspeed cruising on the German autobahn and I do some trackdays also.

I have thought about a larger Oc inplace of the stock one, and then an additional Watercooler in the left wheel faring from the performance kit, so maby Er you could tell me from experience if the stock watercooling is adequate and that Iīm much better of with 2 OC?
Could you post up a couble extra pics of you cooling duct olso from the front of the car, thx

ER dual setup is your golden goose.

I really do hope these are overkill on the track but I wont be able to find out until i get out there in 100F this summer . My goal is to be able to run 15psi on the track. With just the oem oil cooler, I was overheating running stock psi (8-10psi) while short shifting in 70F weather...

I dont believe there are any brake ducts with this kit since the coolers take up the space where the ducts would be. It can be modified or adjusted to make sure there is no rubbing of the wheel on the oil coolers though.
