Possible to reduce the power brake assist in a 997.2 gt3 (iron brakes)? I test drove one and found the brakes to be really overly sensitive. I'd call it the 2nd worst I've ever experienced -- the first being the Audi RS4 which was so overly boosted that a 90 year old could come to a panic stop without disrupting his leg bag.

The brake feedback was remarkable given the sensitivity. I think the feedback would be that much better if the boost could be dialed down.

 

All cars are different, this will be a non issue once you have purchased and driven it for a bit you will forget about it and just be in ore. These are some of the best performing brakes on any car in the world money no object.

Not complaining about the feedback. Complaining about the 80-year old pedal effort required (as in an 80 year old could drive it). I'm not 80.

Any comments on that product? I guess there's some kind of vacuum reserve for the booster, given that it still works when the engine is off, for several pumps of the pedal. If the vacuum reserve is integral to the booster I guess a regulator device wouldn't work.

Two questions:
1. For context, what are you used to driving? What is your gold standard for feel?
2. Do you know if the car was on full stock brakes? I've driven some pads that had HUGE initial bite and tapered with more stopping power. Maybe that was the case here?

I've driven everything from massively over assisted "sports" cars to open wheeled Formula cars requiring a ton of pedal effort and find the GT3 stock brakes to be pretty much perfect for my tastes. Stock pads have pretty strong initial bite but then require more effort for more grab. My track pads are a little more linear. I've can't remember any other GT3 owners complaining about brake feel on the car so I suspect it's you or the car setup.

 

1. I mostly drive a Prius, so I guess you could say that's what I am mostly "used to". For reference, the brakes are fine on that car, the suck part is the way the regen works and upsets the braking.

But I also race Formula Atlantic, which requires serious muscle to work the brakes. That is my gold standard. (PFC01)

I'd say my silver standard is the carrera gt. For a road car it has utterly amazing brakes. I have many miles, street and track, in the CGT.

I always look to the brakes as the #1 aspect that makes a great car. Of course there's the rest, but if the brakes suck, the car sucks, IMHO.

2. I don't know about the pads. I bet that was it though. The other gt3 I drove was totally different and felt "normal" with great linear response. I guess it's the response that is tricking me into thinking it's about the pedal effort.

 

Changing the pads can make a huge difference.

 

Change pads!

 

Never heard anyone ever say Porsche brakes on a GT3 feel bad...ever...geesh

 

^^^ Agreed best brakes on the market for feel and power- everyone raves about them. So easy to modulate.
