Are there any 130mm to 142mm adapters to allow the installation of 997.1 Turbo calipers on a 997.2 base?

Remove one of your front wheels and measure the distance between caliper mounting bolts from center of bolt head. 5.5 inches is 142mm and 9 inches is 225mm

Is your 997.2 base 130mm? What year is it? My 2011 997.2 base is 142mm.

Yeah that's the easiest way. Car is in storage for another month though.

Default Porsche upright caliper mounting spreads (UPDATED):

Front:
225mm - 997.2+ (including 991 GT3)
142mm - 997.1 Turbo and "S" models & all 997.2 Carrera 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.

Thanks. So from this information, six-pot calipers from a 997.1 Turbo or S will bolt right on a 997.2 base because they have 142mm mounting spreads, yes?

Unfortunately it's not always the case. The upright (spindle) mounting spread is one of the criteria that we used to categorized our brake kit design for a complete RB brake kit or retrofit kit with OE calipers. What's released and listed on our web are deem to be accurate and should have no fitment issue.

It may not be appropriate to assume that OE brake components can be directly converted to a different model/year if the upright has the same spread.

What's actually needed to install 997.1 turbo brakes on a 997.2 base then?

Please allow us to explain why and how these OE caliper kits were developed.

We developed our brake kits by measurement and analysis, and we also show you installation illustration and drawings so you can get a good idea of what you will get. However we may not be accurate to answer to a specific model/year over the forum discussion unless items are published on our website, which we apologize and hope other members can help with that.

Kits are fully tested and certified by us with noted "imperfection" in pad alignment per illustration, they are made for a bolt-on installation, but due to the variety of upright casting from OE, in some cases you might have to "work around it" (removing the pad overhang) for a successful installation. Tooling up a special pad to fit the rotor can be done but the kit will cost more... so let's us know if that's what you prefer.

So just understand that these are "retrofit" kits meaning they may not be perfect in all aspect, but it works in "most" part and saves lots of money compared to buying a new brake kit or ever a new car. A little work on your part will make you brake upgrade job more rewarding.

We realized there are always some engineer or brake expert out there that are critical about optional alternatives. However this user publicly criticized our design, without contacting us to clarify his concern, or even seeing these kits. Everything he said was based on his observation, not only this is totally groundless, but also irresponsible and should be discredited.

http://www.6speedonline.com/forums/9...e-discs-3.html

The statement he quoted was not under the brake kit, rather it was used to warn those who intended to purchase only the adaptors (for whatever reasons) which can run into fitment issue that we try to avoid, or for a competition from copying our intellectual property.

RacingBrake is a technology based company. The owner and chief engineer received his BSME degree from NJIT, specialized in thermal dynamics and metallurgy before starting this brake business 30 years ago. He also received 3 US patents in brake designs from USPO.

These kits are well received since our release in 2013 and have satisfied many Porsche enthusiasts for this upgrade conversion which should be the best proof.

We rather spend our time in brake development than debating with those "experts" with only a user name, because our website has detailed the basic and fundamental of brakes and why our design are better under General Information. These kits are offered as an option only with no marketing gimmick, nor it's intended to embarrass or offend some expert who swore and insisted that these 380mm kits can't be done.

Thank you for reading.

Similar retrofit kits offered by RB to oversize OE rotors with OE calipers (Partial list for high horsepower muscle cars only.) just to prove our competency.
  1. Audi R8: 365 to 380mm - 8 piston caliper
  2. BMW (5 to M5): 348 to 400mm - 6 piston caliper
  3. BMW M3/M4 (Iron to CCB): 380 to 400mm - 6 piston caliper
  4. CTS-V (V1 to V2): 355 to 370mm - 6 piston caliper
  5. Dodge Viper (ACR to ACR-XE CCM): 355 to 390mm - 6 piston caliper (Asymmetrical legs)
  6. Ferrari (F430 to F458): 380 to 394mm - 6 piston caliper
  7. Lamborghini Gallardo: 365 to 380mm - 8 piston caliper
  8. Mercedes (C63 to Black Series): 360 to 390mm - 6 piston caliper
  9. Nissan GTR (09-11 to 2012+): 380 to 390mm - 6 piston caliper
  10. Porsche 996/997: 350 to 380mm - 6 piston caliper (Asymmetrical legs)
  11. Porsche 991 CS to GT3: 340 to 380mm - 6 piston caliper (Asymmetrical legs)

For those who don't know about RacingBrake may please take a look at our brake development forum, and see how many exciting and demanding brake projects are going on.

http://forums.racingbrake.com/forumdisplay.php?f=6

Here is a comment we just made to Viper community in regard to why they shouldn't just look to "upgrade" brake pads.

http://driveviper.com/forums/threads...l=1#post203593
I think replacing rotor and pad would be a good idea. Just replacing the pad for the belief from some pad mfgrs' unrealistic advertisement with higher temperature limit pad, is just like taking stimulant or caffeine to get you over it in a short term but is not a healthy solution in the long run.

RB two piece rotors are made with strong iron so they are harder than most OE or aftermarket, so they don't work well with those pads that are made for OE rotors as brake deposit will result poor braking performance:
http://forums.racingbrake.com/showthread.php?t=73

If your normal track pads are not enough to handle your brake task, you should consider upgrading the rotor (increasing the thermal capacity of brake system), rather than defeating it. If you think "upgrading" you pads to those crazy pads (good up to 2000F et.) can do the job then why car companies must adopt to bigger rotors and calipers nowadays for those high horsepower cars, why not just use "high temp. pads"?

Why the newest ACR-E rotor is 390mm, and not 355mm+better pad?

More inquires received lately for upgrading from 142mm front upright to 225mm calipers.

We suggest you read details of this post knowing what's in your car and determine what you like to upgrade. You can ask questions here for a reply or email us for a reply.

This adaptor is exclusively designed and manufactured locally in USA to be bundled with other need components to facilitate most 997 models (except 997.2) with 142mm upright to be able to upgrade their calipers to 225mm mounting spread (GT3 & late 991).

What's the advantage? basically with this adaptor you can upgrade your brake to larger brakes; 380mm, 410mm GT3 pccb, or 394mm CCM brakes with ZR1/Z28 CCB.

Also note the adaptors are to be sold together with our kit only, and not individually.

Default @racingbrake question for you please!

Hi there,
Long time reader, first time poster! But find this forum very helpful.
I am just purchasing a 997.1 C2s here in the UK (but I travel to the US regularly and can bring bits back easily) and I already know after coming from a Lotus that the brakes don't feel strong enough for my liking! At present I'm thinking I'll just upgrade the fronts first (as cash is tight) but is this a mistake with a rear engined car I wonder (would I be better to spend the same money upgrading to a lesser spec brakes but all round? Would big front brakes imbalance the system too much?)
Currently fitted are the red caliper brakes, which I believe are 330mm. I'd like your help, is it possible to use the same calipers and upgrade to larger discs using adaptors? I was dreaming of 380mm or so (big brakes are more exciting than big bhp I say!) but if that's not possible than 355ish is OK I guess.
If you could let me know what is possible and approx costs (or just links to the parts) that would be great!
Thank you
JT

Isn't this for 991 models not 997.1? Thanks

Sorry the link was for 991 reply deleted. This BBK kit is for upgraded calipers will not fit OE calipers.
