Default Brake upgrade for 997.1

If your front spindle has 142mm mounting spread like the red caliper shown in the pictures, your brake upgrade is somewhat limited.



We have caliper adaptor that can convert your 142mm (the red - top) to 225mm (the yellow pccb - bottom)



The good news is RB has a very affordable BBK that allows you to upsize to 380mm (front and rear) using OE calipers - Direct bolt-on, necessary spacer are included:

Front: (380x34)
http://www.racingbrake.com/FRONT-Rot...3-p/2181-k.htm

Rear: (380x28)
http://www.racingbrake.com/REAR-Roto...T-p/2303-k.htm

Or if you are considering to upgrade to GT3's yellow calipers brakes, we have the adaptor for you.



This adaptor converts your 142mm to 225mm mounting spread you can then also upgrade to the latest 991 CCM rotor kits (410x34 front and 390x32 rear) like we have offered in this thread:

For this upgrade you would need to purchase 991 calipers (red or yellow) from Porsche dealers.

Just to clarify - 142mm mount is for 997.1 'S' cars, correct?
Base cars have 5 or 10mm smaller mount dimension and no kits to fit.

Yes, it's for 997.1 Turbo and "S" models. Standard (or base) 997 (05-11) and 996 (99-04) is 12mm narrower or 130mm (5.12") which has different offset and height than 142mm but the adaptor can be made available so once assembled together the spindle will be the same as the latest 991 GT3 if someone owns 996 or 997 non turbo are interested.

997.2 is the same as 997 GT3 with 225mm spread, but not quite the same as 991 GT3 in offset and height however we have the knowledge and resource to retrofit all earlier 911 models to the latest 991 GT3 (2012+) spindle.

Wow, I was just looking into brake upgrades for my base 997.1 without having to swap uprights and wheel carriers.

What I was really looking for was an adapter to run OE or aftermarket 6 piston calipers and 350x34mm rotors on the base 997.1 uprights and wheel carriers ... Something like the Brembo GT kit, but less pricey, that allows us to choose our own caliper.

Do you guys make custom rotor/caliper adapters?

Porsche upright caliper mounting spreads:

Front:
225mm - 997.2+ (including 991 GT3)
142mm - 997.1 Turbo and "S" models
130mm - Standard (or base) 997 (05-11) and 996 (99-04) ; Boxster etc.

Rear:
130mm for all 911 (99+)

We have adaptors for converting 130 and 142 to 225mm mt spread for larger 6 pot calipers, but the rotors sizes are 380mm because that's how the calipers are designed for different mt spread and rotor sizes:

Mt spread /rotor size:
130 /330mm rotor
142 /350mm rotor
225 /380mm or larger rotor

380mm rotor kits require 19" or some special aftermarket 18" wheels.

May I ask what's your wheel sizes and why you specifically asked for 350x34mm rotors, how about 380x32 like for cup car. The reality is the wheel size is what dictates how big a rotor kit can be installed.

We propose a 380x34mm (or 380x32 like Cup rotor) 6-piston caliper Front/380x30mm 4-piston rear set up.

The only difference between 997.1 Turbo/S and the base models (including 996) is the upright with different caliper mounting spread, which we already have the converting adaptors designed/made.

This set up will bring your 996/997 (base or Turbo/S) up to the same size as the latest 991 GT3 with standard brakes (non pccb).

Rabingbrake upgrade kit is designed for a direct bolt on installation, not only it can improve your brake performance, but also give you that muscular and powerful Big Brake look behind your 19" wheels.

And the best yet is you still retain stock upright, wheel carrier, hub bearing etc. nothing else to buy or change (except you have to make sure you have 19" wheels), save you a lot of money and trouble in swapping to 997.2 upright.

If this is something you have been wanting to do but afraid to carry it out due to the concern of involvement and cost, now is the time.

RB did extensive research and development. All Porsche brake kits (iron or CCM) are designed and built to the finest quality in the industry with a freedom of choosing your own brake pads, as we use standard FMSI brake pads which can save your pad replacement cost unless you feel you must deal with Porsche dealer or Pagid pads.

Let us know if this is something of interest to you or any question we can answer.

Can you put a cost together for me and PM for a front/back conversion package?

I like what I'm reading! I have a base 997.1 and would like to purchase my friend's 996 Turbo brakes. Please tell me if you can help me make this all work including the cost of your parts.

Illustration of brake upgrade option for 996/997 classified by uprights.

997.2 with 142mm caliper mounting spread, RB Kit# 2338:
Upgrade to RB 6-pot caliper w/380x32mm center mount two piece rotor
Rotor wt: 22.5 lbs



997.1 and earlier with 130mm mt. spread, RB Kit# 2401:
Upgrade to RB 6-pot caliper w/380x32mm center mount two piece rotor
Rotor wt: 22.5 lbs



Note above two front kits use the same rotor size and offset as Cup rotor, so the same two piece rotors can also be used for Cup rotor upgrade or the complete RB caliper kit.

The front kit also allows you the option for assembly with thicker (34mm ) rotors for heavy track duty by keeping the same hat, or so specify in order. This is possible due to RB's patented center mount design, the offset remains the same regardless of disc thickness.

Rear 380x30mm BBK for both above front BBK, RB Kit# 2433.
Upgrade your rear to RB 4-pot caliper w/380x30mm center mount two piece rotor
This rear rotor has the same size and offset as 991 Turbo rear
Rotor wt: 20.5 lbs



We will package the front & rear kit together as a car kit. All components are in stock except front 130mm adapters are being made with 2-4 wks leadtime.

Drawings shown are for 5-lug hub, Center Lock hub set up are also available.

In order to fit the turbo caliper (142mm spread) you would need to replace your upright because your base 997.1 has a 130mm spread.

We offer economical upgrade rotor kits but they are made for calipers with the same mounting spread as the upright, like this front kit for upgrading to 380mm from OE's 350mm rotors:



http://www.racingbrake.com/FRONT-Rot...3-p/2181-k.htm

The adapters we designed for those kits change your upright both in mounting spread and offset, and they require minimum distance in spread difference and offset for hardware and strength consideration.



Since your OE and Turbo calipers are very similar in offset, and the spread difference in only (142-130)=12mm, so creating a workable adapter is not possible, therefore replace your upright to match the Turbo caliper would be the only way.

If you don't want to change your upright (which is just the beginning of project), like to control your spending, ensure all parts bolted and installed together correctly, with a performance and look improvement, then RB kits should worth your consideration.

Thank you.

How about this solution?
https://rennlist.com/forums/996-foru...t-3-stuff.html

Looks like you have to buy the whole set and not just the adapters.

^^ Wow! Thanks for the details. I'll have to read it again to grasp it 100%!

I was going to run the stock Carrera III 18" rims with a 7-10mm spacer, but I will probably go with an aftermarket wheel some time in the future for track use.

My daily wheels are 19" Carrera Classics.

I'd like to run 18s for competition use as 18" < 200 UTQG tires are cheaper and tend to have better availability for most extreme performance or DOT-R tire models.

As such, I do not think 380mm discs will work for me.

I didn't think I could run 34mm wide discs on the OEM base 997 calipers. Or am I mistaken?
