Default 997.2 base brake upgrade ??

Searched a bit. Found an older thread about upgrading the base Carrera 997.2 brakes to 997.1 S brakes but can't tell if it's plug and play. Anyone do this upgrade?

Was changing wheels/tires to the winter set up and I'll need new pads come summer (along with new fluid). Seems like a good time to upgrade as I was planning on painting my calipers anyway.

So, will 997.1S brakes fit on a 997.2 C2? Will I need different rotors or sensors? I read some not so definitive discussion about that.

It's an expensive "upgrade" just for asthetic reasons.

I recommend just painting you current calipers.

I did this upgrade a few years back - here is the DIY and parts list from my thread.

There are over a dozen other 997.2 DIY's on my thread here in case you need any:

Thanks everyone. EMC - I read your thread and was just looking to see if anyone else has done this upgrade.

Why did you need new sensors? Can't remember if those cost a lot or not. Will go through your part numbers.

Are the 997.2s and 997.1s the same? Are the 987s the same also? The more that are the same the easier it'll be to find a clean set.

Dont think its that expensive an upgrade. If you're planning on changing out rotors and pads anyway then the calipers are the extra 'cost'. Used sets go for sub $8/900. Probably costs close to that to get current calipers professionally painted if I don't do them myself).

I liked them on my old Cayman S and it made pad changes a breeze. It's basically a now or never thing as I should probably order parts this weekend to get some discounts.

Porsche sensors are $43 each. Aftermarket sensors can be had for 1/4 that cost.

As as simple as they are, I am tempted to get aftermarket sensors at my next brake job.

Finally got around to doing this. 997.1 S brakes on a base 997.2. Parts ending in 429/430 for front and 425/426 for rear. Front needs 997.1 s rotor which are a little thicker. Rear rotors are the same. Used 77mm bolts.

Now what to do with the old calipers? Sell, clean paint and sell, clean paint and keep.

I’m interested in this modification as well, so have been carrying out a lot of research on what’s possible with what calipers and discs.

Workhurts- appreciate you confirming you carried out this with 997.1 S brakes. Could you confirm that 997.1 c2s brakes and c4s brakes can be used to fit onto 997.2 base c2, and that it was a direct bolt on?

If so that’s great news! Was thinking whilst at it to upsize the discs to 350mm turbo. Would it be a simple matter of using correct size spacers to do this front and rear?

An alternative solution was to install the 997.1 or 997.2 turbo/GT3 6 pot caliper (if I can find for right price) - does anyone know whether this will directly bolt onto 997.2 c2 non S without spacer and still accommodate the 350mm disc?

I have seen a few 991.351.424 6 pot calipers available - would these fit the 997.2 base?

Appreciate any guidance anyone can give me.

It is not an "upgrade". Porsche brakes are famous for being the best ever. In time there are new designs that are improvements over previous systems. The 997.2 Carrera brakes were a new design to replace previous systems, therefore they are "better". The reason- they are much stiffer and having less flex they are quicker to react ,bend less and due to the greater stiffness they eliminated the goofy damper pads. Closed back calipers are always stiffer than open backs. Can you change pads quicker with open backs? Not if you have to fish out the damper pads. The time to jack up a car, remove wheels , is 95% of the time involved unless you have air jacks and center lock wheels and you are at the race track. Explain why you need to "upgrade" the brakes?

Please send me a PM if you want to sell your stock front calipers. No need to clean or paint them.

Floyd- thanks and appreciate your thoughts on this. I do understand the closed caliper will be stiffer than open and changing these may not strictly constitute as being an upgrade to current factory brake performance, so I referred to this change as being a modification rather than upgrade.

My reasons are that I need to replace discs soon, so thought it would be great time to upsize to 350mm. There are caliper spacer kits out there utilising the base c2 closed calipers but the front one will necessitate use of a 28mm thick rotor (ie a turbo rear disc) due to the max thickness the closed caliper can accommodate and this particular solution generates a 7mm offset.

I have 9” ET45 front wheels which are a pretty aggressive offset. These line up flush with the wheel arch after careful alignment. I’m trying to find a way to maintain the current wheel poke, ie not stick out the arch and do not want to introduce more camber.

Therefore I thought about getting S calipers which would allow for a 350mm turbo front rotors without any additional offset. These calipers are more readily available and as workhurts says at this point the additional cost is just for the calipers and adaptor/ spacers.

Default Retrofit 996 turbo brakes

Would a set of 996 turbo PCCB ceramic brakes (which has calipers 6 pot front and 4 pot rear along with ceramic discs 350mm front and rear) be a direct fit a 997.2 non S?

Would appreciate anyone’s thoughts on this and confirm if this can be made to work without modifications to the uprights or calipers.
