These might be of some use to someone, not mine or anything to do with me.

theyre boxster S pads unfortunately....

Working on a 335mm rear which'll be low cost, uses a separate handbrake Caliper which are expensive.

First kit goes on a TTRS this weekend funnily enough

any more info/news???

Yes well the TTRS has an extra track width of 10mm per corner allowing me to get all sorts of bracketry in there to replace the OEM setup completely with RS6 335mm rear drilled discs, porsche calipers and brembo handbrake calipers. Just done 9 kits for now and they've all sold

Working on something more cost effective for MK5/6/R32 the problem is these RS6 discs are £600 retail but are dimensionally perfect and directional

But heres Jamies TT with the kit fitted, the other 8 kits ship this week all over from Harrogate to Sydney Australia

Ok the other mod that I thought might be of interest to the NQS users is a rear caliper upgrade.

Basically the standard GTI Caliper has a 38mm piston and is configured for a 12mm wide disc.

Next upgrade along is the S3 or R32 setup goes to a 41mm piston and a 22mm wide disc

So what if we had a 41mm version of the stock GTI caliper which was plug and play.

Dont forget we always talk about diameter when we talk about our discs, brake engineers never discuss diameter as it doenst matter for sh1t.

Radius and effective radius at that is where its at.

So we use a 286mm disc instead of a 310mm disc thats a 12mm reduction in radius, if we use the new caliper that hydraulically is the same as the S3 rears, we in essence get S3 bias for GTI money.

So in keeping with the Low Cost high performance ethos of the NQSBBK we now have an alternative upgrade path which weighs an unsprung 9KG less for practically speaking the same performance.

Its here.....we've got some they're off a Caddy van, theres an amount of modding to do to them as they need the handbrake bracketry and feed pipe swapping over which normally works as part of a refurb process. Jonny at BCR has two or three sets stripped down.

Theyre on a members car on here, he may/may not want to cough to running them. The rears were fitted at the same time as the NQSBBK was so difficult to do a like for like but safe to say with the 41mm rears and the NQS the car feels planted under braking as you would expect.

PM me for more info or we can discuss it on here

Due to balance questions this might be of interest for some of you.
Hope I did get all the collected data right.


piston size/area



1. stock front caliper:


Golf/GTI - Ate FN3 54 mm caliper: 2290 mm²

S3/R32/R - FNRG 57 mm: 2552 mm²



2. aftermarket - proper match:


Boxster: 40 mm + 36 mm > 1257 mm² + 1018 mm² = 2275 mm²

Brembo GT caliper A: 40 mm + 36 mm > 1257 mm² + 1018 mm² = 2275 mm²

Stoptech ST-40: 38 mm + 34 mm > 908 mm² + 1134 mm² = 2043 mm²



3. aftermarket - poor match:


Forge: 707 mm² + 1046 mm² + 1164 mm² = 2917 mm²

Q7/Touareg/Cayenne (three variants):

34/36/38 mm : 907.920 + 1017.876 + 1134.115 = ~ 3060 mm²
32/36/38 mm : 804.248 + 1017.876 + 1134.115 = ~ 2956 mm²
30/34/38 mm : 706.858 + 907.920 + 1134.115 = ~ 2749 mm²



4. master cylinder diameter:

- 22,22 mm >  388 mm² (Mk.V GTI)
- 23,81 mm >  445 mm² (Mk.V R32, Mk.VI GTI, Golf R)
- 25,40 mm >  507 mm² (RS3 + TT-RS)



If you know the piston diameter: Pi * radius² = area

PM me for more info or we can discuss it on here

Dave, how about opening a new thread?
I must say I am interested in this... Will we keep the stock discs or will these be replaced with vented ones?

[the bruce]

I'd bet if a stock Caddy caliper is used it needs to be a solid rotor.

ps
Brembo caliper added

GTI is 23.8mm All models

[the bruce]

Thx, Dave.  

Refering to ETKA there are both 22.22 and 23.81 mm. Possibly some GTIs exported overseas had the 22.22.

Found some more - Boxster S and 993/996 Turbo:

[cheungy]

So? What is needed & Cost ??? 

New Thread for the NQSBBK would be good idea 

[jimk04]

996 turbo do work well

[Dan648v]

Interested in this rear nqsbbk! And more importantly who is getting it in Harrogate because I don't know anyone in my town on here??.....

[Tfsi_Mike]

996 turbo do work well

Even if you do say so (and engineered it) yourself! 

[jimk04]

No Mike mine are just 996. WasWas referring to yours!
