No track as of yet, but hoping to get out this year.

The general train of thought is that 997 calipers are essentially identical to the 996 GTx cars only with a slight different offset. The only slight issue is that since the 997 rears have larger pistons the brake pedal ends up with slightly more travel since it has to move more fluid. The compromise for many has been to change the fronts only and leave the rears stock essentially mimicking the 6 GTx setup.

 

I am running the 997 fronts with the 996 rears with pagid yellow up front and pagid black rears for DE and it is awesome. I have the 997 rears with stock pads, rotors and calipers if anyone wants to but these. They will fit I just went what I had seen other do and liked. They have only a few thousand miles on them. PM me if interested.

 

I'm running the full front/rear setup with no issues... Bolt on and I have tracked the car! Do it and play with pad compounds to help adjust bias if you want to get super serious...

 

Hi,

Did you feel differences in the brake pedal?

The power break is much bigger with the new breaks?

Thanks

 

Brake pedal is slightly longer but I also did Motul RBF600 along with SS lines. You get used to it very quickly. I've also noticed that the rears do seem to wear a bit faster than before (brake bias pushed rearward due to change) but that's a worthwhile tradeoff and so far, so good.

Brakes stop well but mainly resist fade, etc... I cooked my stockers at the track which is what prompted me to make this jump. Plus, they look freaking COOL!

 

But the 997TT calipers/rotors brake much better than the original 996TT?

Regards,

 

I would say slightly, yes. Keep in mind that the stock brakes are actually pretty amazing with the right lines, pads and fluid (and what condition they are in). Where they can reach their "limits" is in pushing them with added HP/abuse and they overheat and boil fluid, etc... If your TT is modded and you drive it hard, it's a no brainer for the right price IMO. I always want more brake then I'll ever need...

Make sure and run good pads, fluid, lines with either setup but feel good that you've bigger calipers and rotors to disperse heat and keep you on the road! Not to mention some added clamping force. Sticky tires make a big difference too as brakes are just simply one variable in the larger performance equation...

 

Hi, I have been running the larger custom 350mm slotted rotors (via spacers & longer bolts) on my car with the stock '01 TT calipers, GT2 ducts, PFC 01 pads and Motul 600 fluid for a few events and still ended up cooking a caliper. I'm wondering just how much more heat dispersion I'll get by adding the 6-piston calipers? Considering the SunCoast kit.

TIA

If anyone is interested I have stock 6 piston front calipers and rotors for sale off my 997TT.

Pm me for price.

I am going to post in the sale thread too.

 

I am no expert but I found that with the 6 pot fronts and better pads for DE you could brake harder and later and also did not need to stay on the brakes as long because they stopped so fast. I think this helps with the heat issue as they are not applied as long. I also have the cup front ducts and my front lip does funnel a tiny bit more air through the bumper than the non funnel flat cutouts on the stock fron lip. Bottom line is these brakes resist fade better and you do have a larger heat sink. The pads and technique are where the bite is comming from. Just my 2 cents. Laslty if you compare the pads from the 6 and 4 fronts the 6 pads are MUCH larger. The pagid pads actually were so thick that I had to remove the anti squeal inserts so they would fit.
