Hmmm.....there may be something to this brake fluid thing.

The components for the cooling ducts are available from Paragon Products...http://www.paragon-products.com/Brak...4-bp-m030r.htm
On my 951 I have AIR fog light ducts and a horizontal Mocal oil cooler sitting below each duct in the stock cooler location so you should be able to fit them in an S2 as well. As stated, another option would be to use 968 brake cooling ducts which scoop up air from beneath the car.

Thanks for the link.
Seems like a cool idea. Wonder how much more air gets pushed through there than stock?

Here's another option for a duct backing plate:

One nice thing about this option is that it removes the heat-soak-causing dust shield, and thus should help keep things even cooler.

It is true that technically speaking ATE "Super Blue" is not DOT compliant. The FMVSS (Federal Motor Vehicle Safety Standard) 116 states that the color of DOT 3, DOT 4 or DOT 5.1 is clear to amber in color and DOT 5 (silicone) is purple in color.
FWIW, the moisture uptake of Castrol SRF has nothing to do with its high boiling point. And in fact SRF does NOT have a moisture uptake that is wildly different that any other high performance DOT 4 compliant brake fluid. What Castrol SRF has is a very high wet boiling point due to a unique to brake fluid base material of silicate ester. All other DOT 4 brake fluids are by definition borate ester based.
All that said, the silicate ester base of Castrol SRF gives it a few rather unique behaviors one of which is an almost complete lack of recovery in the event you boil it. Very long explanation as to why that is but suffice to say if you boil SRF you have to immediately come in and bleed out the boiled fluid. this is in difference to the other brake fluids which will recover have cooling down from boiling. That's not to say you shouldn't bleed the system if you have boiled the fluid but is to say that if you manage to boil the fluid in a race, with a borate ester based fluid you can let the brake cool a bit and still have enough brake to continue whereas wtih SRF you boil it and you're headed to the pits.
Castrol SRF is good brake fluid and we are honored to be considered int he same category. Yes RS683 is expensive but you get what you pay for. In our relationship with Andretti Autosport we have learned that RS683 has extended the caliper seal life by 50% - 100% over SRF.
FWIW, we recently tested (independent lab) most of the major brake fluids, Castrol SRF, Brembo, AP Racing, Motul, Endless and ATE. While I will not provide specifics I can say that other than RS683 only one other brake fluid met all the DOT 4/FMVSS 116 regulations and met or exceeded all its stated performance specifications. For example, one particular fluid that claims a dry boiling point of 617 F tested at 581 F. Again, you get what you pay for. (But I will admit bias)

Yep. The lab tested all the brake fluids submitted for ALL the DOT 4/FMVSS 116 (Federal Motor Vehicle Safety Standards 116) requirements and of the test batch, only two brake fluids met all the reuqirements and met all their claimed performance specifications. Those two brake fluids were Castrol SRF and Prospeed RS683.
FWIW, with the exception of RS683, we purchased approximately 1 gallon of each of all the brake fluids from well known dealers across the USA. We purchased from these well known dealers in order to have (1) a somewhat random sample and (2) to increase the probability we were receiving reasonably recent production product.

I think it sucks that Rennlist banned Prospeed_Motorsport for talking about the specific performance tests for a product. I guess only site sponsors can respond to questions, pretty fascist. I will return to Pelican now.

It was because of his user name.They're tring to say he was advertising.
I've never read a post on here with Michael trying to push his product. Since he's had the same user name for years why ban him now?

Not if you are running a website as a for-profit business and expect vendors to pay for exposure. You also have to protect the vendors who do pay from ones that do not pay but might still benefit.

Either way - I appreciate the thread...I'm pulling my calipers soon to paint them and put new brake pads on - I bought a power bleeder and just bought a couple quarts of this stuff to replace what's in the tank.
Any significant differences with the clutch pressure when using this fluid?
