brakes question

[audinut]

will a 996 351 425 caliper fit on a porcshe fitted with a 996 351 429 caliper?

[Jamo]

Hell no

[audinut]

hmm whats the difference as the porsche in question originally had a 996 351 425 caliper on it but has been upgraded to the turbo caliper(but the porsche isnt running a caliper adapter etc) is it just the disc difference?

[Jamo]

Different mounting points, bigger discs, wider discs, different pads

429 is GT3 MKI or 996 TT calipers
425 is Porsche Boxster

[audinut]

so how can the 911 i have up the yard be running the 429 caliper with no adapter?

[Jamo]

Simple fact they aren't

sorry to jump in here guys but can they (429/430) be used as an upgrade on front??still use a8 discs?? cheers

[audinut]

yes vrs sell the adapter , and you can use the larger a8 armored disc 324mm i think

[Jamo]

Yes but you are better using the merc disc as the A8 disc is 30mm width and the merc is 32mm or 34mm can't remember which. w429 were designed to used with a wider disc than 30mm

In saying that Bambridge and VRS have off the shelf brackets I think for the A8 disc so that does make it easier there.

Thanks jamo , it really is only just a question... even from the picture (to me the turbo caliper looks like it has the same mounting points as the non turbo caliper) yes its definately bigger i totally agree there.

Maybe the porka has had the hub changed ? (i dont really want to go to a porsche forum i just wanted to know if it was worth nicking those brakes and trying to fit it with the others )

bambridge doesnt have brackets for the 429's only will at vrs

[Jamo]

bambridge doesnt have brackets for the 429's only will at vrs

Well that's not strictly true as Bambridge makes them for VRS, it maybe though thinking about it be that VRS owns the bracket mount drawings

[audinut]

As i said in the PM, if they are 429/430 brackets contact Will@VRS, i spoke with him a week ago and he still has some in stock
