Has anyone done a conversion from a 996TT Gen1 PCCB to steel rotors?

I've done a lot of research and see some conflicting answers. A couple of the regulars on the 996 GT2/GT3 recommend steel rotors from the GT3 cup cars, but now my understanding is these will not fit the front of the 996TT because of the AWD.

Some other users have posted custom machining solutions for the hub, but I'm looking for something out of a box that will be a direct bolt-in and work as well as factory steel brakes.

Any recommended leads for suppliers/distributors that offers a steel conversion solution for the 996TT?

Which pads would fit the PCCB calipers if the car will be driven on the street and not for competition use?

I'm going to answer my own question. I found a solution for a retrofit kit from suncoast here:

Some other posters are also mentioning that the 997TT rotors are a direct bolt in replacement without having to change the PCCB calipers. Anyone confirm?

I upgraded my turbo to the yellow PCCB calipers and went to 997TT rotors initially. Since I track, I changed the fronts to Girodiscs. Everyone of these mods were direct bolt ons. By looking at your avatar, it looks like you don't have a turbo so I don't know if that applies to your car.

Haha. Thanks for the info. I'm looking to purchase a 996TT and it has PCCB with chipped rotors.

I've got em, ready. Bolts right on - GiroDiscs

Craig at Rennstore is who I bought the Girodiscs from. Good product, good price, and a great guy to deal with.

k.a.

During the spring I was doing the steel conversion, but struggled to find input on a solution that is a bit less pricey than Girodisc. I just wanted to share what set-up I ended up with, just in case anyone else will go through the same conversion:

Front
- Sebro slotted rotors for 997 Turbo. Sebro part # 909356
- Pagid RS29 (yellow) pads

Rear
- Currently on OEM 997 Turbo rotors (will change to Sebro slotted rotors for 997 Turbo or Panamera Turbo depending on fit)
- Pagid RS29 (yellow) pads

So far a direct fit, except for that there were no room for the brake shims. However, I will install the brake shims when the pads have worn slightly.

If you don't want to go through the brake shim issue, then an alternative would be to install PFC pads which seems to be slightly thinner than the Pagid pads.

997tt or 996GT3 sebro blanks or slotted rotors...115 bucks a piece...girodiscs if you insist but not worth the different price points in my opinion

havent found sebro slotted rears anywere. that link only has the fronts. (great price) but the rears are solid disc or drilled no slotted in 350mm

I'm running 996 GT3 PCCB calipers with 997TT Sebro steel drilled rotors and OE pads for steel rotors on my turbo. Very happy with this set up and it is quiet.

I think the hub swap to GT3 spec stems from when people were doing the 6 pot conversion on the 996 Turbo using the GT3 spec rotor before the 997TT existed. Going to GT3 P/N rotor requires a different hub. With the 997 Turbo rotors you do not run into this problem. It all bolts up with no issue and no need to machine the hub.

I will go drilled or blanks in the rear whichever are available even though I'd rather use blanks..and most the gt3 guys I track with do the same. the life on these rotors are unreal with aggressive pads like the rs29 or rs19s

its a cosmetic thing for me. i like the rotors to match front to rear

Jferrante

gotcha makes sense.

Resurrecting this. If I want to remove the PCCB discs from a Turbo and add Iron/Steel rotors, I believe all I need is to purchase 4 997.1 rotors and pads, is that correct?

Also, at what thickness do you change out the pads on PCCB's?

Kind of curious as to why; short of tracking PCCBs to dust, they are far superior to the standard brakes for street and drivers events.

I replaced all pads, pucks, lines and hardware at 50k miles - the rear pads were tapered, something I gather is normal. Pads had a lot of life left in them. Wear are the rotors at 50k miles was barely perceptible.
