Default Probraking fronts installed

I installed my Probraking Super SL4 upgrade last week. I've attached some pictures below. I have a track day at Gateway on Tuesday where we come off the front straight at 130-140mph (depending on my courage in the bowl) to 40 for turn 1-2 combo.

Last year with my stock Carrera brakes I was boiling the fluid (ATE) after only a few laps. I did change out to Hawk HP plus pads on a second round at gateway last year to see if they made a difference on early fade. They were much better for the few laps that the fluid lasted.

Anyway, I was not willing to give up the look of my anniversary Fuchs and the Lindsey rims were very hard to come by. Seems that 16x6 Fuchs have become a high demand item these days. Dave at Lindsey told me he needs 4 rims to cut out the centers and build their two piece rims. So, upgrading to the "Big Red" or equivalent packages would have required a different style rim.

So here they are, Dave at Probraking was very accommodating with quick shipping (overnight!), pad info, and explaining his hardware strengths and weakness'. I was very impressed with the quality of the components in the box and even my skeptical mechanic admitted they seemed well made and were an interesting solution to the Fuchs/brakes conundrum. He's a Porsche purist so he wanted me to hold out for Lindseys and Big Reds.

Tuesday will be telling as I'll see if my $1800 was well spent.

Still using ATE for this one. I may take along some of the Castrol SRF now that you mention it.

The blue or gold should be good. The only other consideration is ducting to cool the brakes.

I am looking into my options on the cooling duct work. There are kits from various sources but they all seem overpriced for a simple duct off the front A-arm or spoiler.

Any suggestions?

Couldn't I simply get some high-heat ducts and run them off the front air dam to the backs of the wheels?

BTW...I'm alternating between blue and gold each bleed.

Jim, where did you buy your brake cooling parts?

My backing plates were on the car when I bought it. I just connect them to my air dam. Hose is available from BSR, Pegasus Racing, etc.

You don't want to aim the hose at the caliper/rotor/wheels, you want to have the air go into the eye of the rotor to cool both sides evenly (but I suppose something is better than nothing).

The brakes were excellent all day yesterday and we ran at least eight 20 minute sessions on a track that's hard on brakes. I'm impressed with what Probraking has done and I'm able to keep my 16" rims as I wanted. If I run at Road America I'll probably need cooling ducts but at Gateway I did not.

Do they use the stock rotors?

They don't seem to have a website.

No they use custom rotors. Dave seems to have shut down his site since Pelican started carrying his kits (maybe a coincidence). If you're interested check out Pelican part #PEL-PB-SUPER4

or just go here

How much are replacement rotors and where do you get them from? Are they readily available? One good thing about the Big Reds is that any P car dealer can get the 993 TT rotors.

That was one of my thoughts, the other is I do not want to add heavier rotors to the car. My main goal with my carrera is to reduce weight, nothing else. I would add an LSD though regardless if they are heavier
