991 GT2RS

[hdoherty]

I have just been reading the GT2RS report by Ben Barry in the Total 911 issue 177.
He says the Porsche Ceramics Brakes are the biggest failing , I am gub smacked as Ive always wanted PCCB on my car as i believe
they are the best in the world but could not justify the cost with my style of driving.

Really has Porsche put a 991GT2RS on the road with poor brakes [8|]

In what context is he criticising them?

My experience of pccbs, from 996.2 GT3 and 997 GT3 to 991.2 GT3 (and others in-between) has only been positive.

Sorry, haven't read the report but I have PCCB's on my 911 Turbo S (as standard) and as far as performance is concerned have found no real advantage unless they get seriously hot plus they don't rust! I track my car in a moderate fashion and have found no real difference to the steels on my previous 997 Turbo. I probably don't push the car enough.

However I have never replaced pads before I sold my precious Porsches (964 C4, 996 C4S, 997 Turbo, all around 30,000 miles) yet I have had to replace my current pads at 14,000 (circa £1,300) yet my pattern of driving has stayed the same. 3 track days a year plus some continental motoring and almost daily use at home

I dread the time when the discs themselves need replacing as mine were faulty on delivery and were replaced under warranty and the invoice (I insisted on an invoice so that I could prove that the faulty batch number were replaced) showed the at £3,000 each disc.)

Depending what I buy next if there is a choice I will stick to steels.
Cheers

I'm sure someone will correct me if I am wrong but I understood Carbon Ceramics to 'come in to their own' when extreme temperatures are experienced - ie. they maintain performance when super hot while steel brakes can often experience fade under the same circumstances. To me this, extreme temperatures translates as either hard constant use (such as long twisty mountain roads) or track use. The amount of heat generated by any braking system is proportional to the speed x weight of the vehicle it is trying to slow down. Since 911's are, in general, not particularly heavy cars, the heat generated under normal road use might not be sufficient to get the CCB's up to a good operating temperature and therefor a steel disc - which is designed to work at lower temperatures - will likely be more effective for 'everyday driving'. Prior to my 991 I had an RS4 - a big fast and heavy estate car. In the RS4 community, CCB's were viewed as highly desirable and very effective. Amongst 911 drivers though I see this as being much less the case.

Has the same sized rotors as on my recent 991.2 Turbo 'S'. These operated superbly and were one of the most outstanding features of this car. []

Bearing in mind the TTS is significantly heavier than GT2 RS, I can't accept this car would be under-braked.

I tend to take the opinions of journalists with a pinch of salt since their driving skills and condition of their press cars are so variable. However, I think Porsche has a great track (literally []) record in respect of stopping power. []

My last 4 cars have all been fitted with CC brakes and I wouldn't willingly return to steel rotors. They do have a different feel though and take a little time to get used to.

Haven’t seen issue 177, but the article on the GT3RS in the previous issue 176 says the PCCBs ‘instill immense confidence’. So take your pick ??
