Hi all, looking to upgrade the tiny disks on my 1.5 Kamiq. Am I right in thinking its basically Polo suspension so the Polo GTi parts will fit?

It's possible the following won't work, so treat the following information with caution. The 312x25mm front brake discs on the latest Audi A1 and VW Polo MK6 are different.

 

VW Polo MK6 312x25mm front brake discs

 

 

Latest Audi A1 312x25mm front brake discs

All these parts could add up to over £800 partly because the wheel bearing housings don't appear to be available aftermarket yet. The VAG price could be over £400 just for the left and right wheel bearing housing.

 

These parts are from the VW Polo MK6 GTI and will probably fit the Kamiq with 276x24mm front brake discs. If you have a Kamiq with 256x22mm front brake discs you would probably also need new wheel hubs with the bigger 78mm outside diameter bearings, as the wheel hubs that are used with the 256x22mm front brake discs on the Kamiq use smaller 72mm outside diameter bearings.

The 312x25mm front brake discs on the VW Polo MK6 and Audi A1 MK2 are different (and so are the wheelhubs). The brake calipers, brake carriers, and wheel bearing housing are the same. So why are they using different brake discs??? The reason appears to be that they use different wheelhubs (the part that the five wheel bolts screw into). 

 

Different front brake discs on these two cars

2Q0615301N VW Polo MK6 Front brake disc 312x25mm 5/100

2Q0615301J Audi A1 MK2 Front brake disc 312x25mm 5/100

 

Different wheelhubs on these two cars

2Q0407621A Audi A1 MK2 wheelhub

2Q0407621B VW Polo MK6 wheelhub

 

So if you use the Kamiq wheelhub with OEM part number 2Q0407621A (which is the same as one of the wheelhubs that the Audi A1 MK2 uses) you will need to use the Audi A1 MK2 312x25mm front brake disc with OEM part number 2Q0615301J.

 

This may explain why the Audi A1 MK2 with 312x25mm front brake discs has build code 1ZA and the VW Polo MK6 with 312x25mm front brake discs has build code 1ZB, ie. they are not the same, although some parts are shared as mentioned above.

Thanks for this Carston, more complicated than I thought but very useful info.

A photo of a wheelhub

 

I suspect VW used the different wheelhubs on the VW Polo MK6 GTI, ie. 2Q0407621B instead of 2Q0407621A, to move the front wheels out by about 4.4mm, which could have been for improved handling and/or steering response, but I suspect it was for cosmetics, ie. to fill the front wheel arches. They could have just altered the offset of the rims by 4.4mm, but that would also have effected the rear wheels and from the photo below the rear wheels were already filling the rear wheel arches so didn't need to be moved out a further 4.4mm.

@wobble52Are the 'Tiny' brake discs and pads and calipers lacking in braking performance on road, overheating or such?

 

Or are you changing them for something better looking, or for track use.

 

Pads, brake hoses and fluid changes could improve the braking if that is all that is required.

Often worth just upgrading the pads (and maybe discs). Bigger discs weigh a fair bit more so handling will be compromised.

Worth checking out any Karoq projects with bigger brakes.

 

Scala.  Silence came the reply for this members post.

Hi, partly cosmetic but also I just can't believe they're adequate for a 150hp car. However I wasn't planning on being the first to try this....

 

The brakes / ABS / ESP will be up to the job as much as the factory fit ECO tyres will be at gripping the road surface.

 

They got passed for Type / Approval and will or should pass a UK brake test at a MOT.  Not that that says much.

Totally agree with toot

 

braking is going to be limited by choice of tyres, if tyres don't grip and start to lock up, the abs will ease the brakes, so need to change tyres first before considering bigger discs
