The 996 GT3 steel has
350mm F
330mm R

The 997 GT3 steel has
350mm F&R

The 996 GT3 PCCB
350mm F&R

The 997 GT3 PCCB
380mm F
350mm R

Also of note for the 997 GT3:
Newly configured brake force distribution now conveys even more brake power to the rear axle right from the start when applying the brakes.

Aren't there cup rotors out there that would be the ultimate non-PCCB setup, at some fraction of the cost of PCCBs?

cosmos

Stedge,

Yes. Contact Viperbob. He is a G-D when it comes to these cars.

Wait a minute; only 100 miles per track day? What kind of track day is that? You going to VIR? That's about 30 laps a day. You need to be DRIVING that thing, man; I put in that many miles before 9:00AM!

If that is how your track days are, go ahead and get the PCCB. They will last forever.

db,

Race Organizations let you on the track with the Techquipment bar??

If so which ones?

db_gt3

I guess if you call Jack's group a race organization, then, yes.

Really, I don't know which one would. I don't wanna race my pretty car, just have lots of fun with the boys. When I'm ready to race I'll get the cupcar or something even faster.

What are you driving right now?

rmag

Yea, East coast PCA clubs are always packed events. Usually only 3-4 25-30 minute run sesions a day

Yea, been to VIR a few times. Did Watkins Glen for first time this year. Man is that a sweet track!

db_gt3

That's why I avoid those PCA ***** like the plague; or any crowded, beginner oriented event for that matter. I think my wife is right, I realy have become a primadonna. Oh well. More track time means more fun.

jbeanstalk

What about the unsprung weight difference? I understand the ceramics are significantly lighter - those of you who have driven identical cars with both setups - you couldn't tell ANY difference?

cosmos

Nothing fun and exciting.



Jacks group is a race machine!!!!

FYI, just watch out for those pesky little english cars. They are funny looking but fast.

I dont know what I want. I am getting tired of buying cars only to sell them a few weeks later and lose the sales tax. I need to get a dealer license like the Wattster.

I have an Oct build M coupe and might take that on a 1 yr lease. That way I get the car, but dont have to spend the sales tax. I just sold the M3 race car and lost $20k in 8 weeks. Worst financial move I have ever made. I kick myself every day for it

I am just confused and need to be put out of my missery

I also have been unemployed for a bit. I sort of like it, but the wife really wants me out of the house. I think I am getting on her nerves.

db_gt3

Yeah, Jack is the man. A true gentleman who just wants us all to be able to drive like men. He's the Dad I should have had growing up. I swear he is at the track as much as Craig. I can't keep up with all of the days he puts together, but I try.

As for the Lotus bunch, there are a couple of quick guys who run with us, but still can't really hang with a properly driven GT3. Usually about 5-6 seconds slower per lap at Buttonwillow(unless its Lou driving and then its about half that difference). Jack took delivery of the blown Elise, which should be a fun one to watch. I think he is going to unveil it next week.

Now I remember looking at your M3 race car web page; that thing is hard. Why did you sell it?

What ever you get, dont do what Watt did and get the Chevy, that thing is a lame duck. Last time we were at Buttonwillow the new owner showed up with it; the motor decided it didnt want to run anymore after about four laps or so. No one could figure out why it died and it ended up getting flatbedded all the way home. Of course the GT3's just kept getting stonger throughout the day; even as we logged over 100 laps. Ah, the joys of this beautiful machine; Porsche really got it right on this one.

Gen 1 and Gen 2 PCCB

The v2 PCCB brake rotors have 400,000 carbon fiber bundles. Which has been increased from 3,000. This leads to much more longer life. A new lost core forming process aids in production which will ultimately lower costs for replacement.The rotors with their new arcus internal design allow less frictional air movement internally. So that at 200km/hr more 250 litres of air per second. This is a 20% increase in efficiency over the old PCCB's
. So:
TAKE A GT3 WITH 381BHP
takes only 14.3 secs to go from 0-200km/h(124mph). The new PCCB v.2 only takes 5.4 secs to DECELERATE form 125mph to zero! That equates to max brake performance of 1,200 HP!

Yes, but don't the "free" iron brakes do about the same?

PCCB Gen One are hopeless mine failed after 15,000 (mainly road) miles on my GT2...Porsche are of course blaming me! The carbon surface of the disc separated from the underlying silicon carbide and destroyed the pads (which were approx 60% worn) after approx 40 miles.I have reported this to the UK Department of Transport as a saftey issue as Porsche UK are totally uninterested - other than confirming that even brand new pads can be destroyed in 120 miles once the surface of the disc has failed. There is no warning other than the pad replacement light illuminating (indicating 1/3rd of the pad remaining at that time).

I hear that the Gen Two PCCB wear almost as quickly when hot...so beware!!
