Try this link for upgrading OE's 318mm to 330mm rotor:
http://www.racingbrake.com/Two-piece...S-p/2022-k.htm

We can't be 100% certain but if your OE front caliper is 4-pot and with 318x28mm rotor, then this would be your plug and play kit to instantly increase your braking capacity.

You are right in rotor thickness, this OE 4-pot calipers only takes 28mm rotor (between pin is 31mm), so we keep the same rotor thickness at 28mm but enlarge the rotor diameter to 330mm.

For 18" wheels you technically can go up to 350mm rotor kit, but if you retain the use of original OE calipers, 330mm is the largest rotor we would recommend. (it may even fit 17" wheels)

Hope this answers to your question.

Noted. Thank you!

How do your kits compare to GiroDisc's 340mm disc kit for base 997.1s? If I understand correctly, RB's kits have different hat-to-rotor mounting hardware?

RacingBrake

RB two piece rotors feature patented "center mount" and convergent vane design (vs. conventional surface mount and curve vane):





Illustration of how the hardware function (sliding effect vs. conventional floating) during heat cycles:



RB iron discs are of high carbon, with alloys and heat treated before machining to assure the delivery of consistent high brake torque, and highly resistant to cracking and warping under extreme heat. All our discs are certified to have a hardness of 200-230 BHN (Brinell Hardness)

How we make the rear rotor light weight comes with emergency drum brake w/o short-cut (just aluminum hat) like others?



Why RacingBrake?

RB makes more two piece OE replacement rotors than all the competition combined.

All item description not only contains weight comparison to OE (one or two piece), but also has dimensions (diameter and thickness).

Recently we introduced a rotor search by dimension for Mercedes due to it's complexity of years/models while a lot of them use the same rotors. This can help customer to positively identify their rotor w/o having to go through year/model/VIN# etc. and can still receive incorrect parts.

RB has been in brake business since 1986 and in early 2000, we were the first brake company introduced the first two piece rotors for STi and EVO 8 - The two most popular motorsports cars at that time.

Dear Warren,
I have a '07 997.1 C2S and I plan on upgrading my front rotors to the Yellow PCCB 6 pot calipers from a 997.2 turbo.

My caliper mounting points are smaller (142mm) than those of the calipers (225mm).

I have also purchased a pair of 380mm GT3RS rotors 1 Front left brake disc, part number is 997 351 409 91
1 Front right brake disc, part number is 997 351 410 91

As such i will need to purchase an adapter that will allow me to mount the new Calipers and ensure they will handle the said rotors.

I would be very grateful if you could advise me on;
1. Will the adapters you make/offer work for my setup and,
2. If so, as I cannot find the link on your website to purchase said adapters. could you kindly point me in the right direction?

Thank you

I believe your same question via email was replied. If not let us know.

Thanks

Hi,
I have been waiting for a reply both by email, and on your RB forum but don't seem to have received anything. Would be grateful if you could re-send?
thank you

it's exactly the same question.
I did not receive any emails from you yet. Would be grateful if you could re-send the message.

Thank you in advance.

so lets say I want to use 380 stock rotors. Do you sell the spacer separately?

Does my 997.2 base model have 225 or 130 spacing?
thanks

RacingBrake

Your 997.2 base has 142mm mounting spread.

Dan GSR

would 997.1 turbo rotors and caliper fit my 997.2 base?

I'm interested in this answer as well if anybody knows.

So is a 2012 997.2 S 142mm or 225 according to this:

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

I have a 2011 997.2 carrera base. I personally measured it at 142mm. The c2s and other 997.2 cars may have 225 but mine is without doubt 142mm. ]
