i'll try and weigh mine later  

disc 312mm 7,75kg
caliper and carrier 5,5kg

 

[Janner_Sy]

what could also be handy is if you could get the weight of the standard control arms and the cupra/S3 aluminium control arms as they are used to offset the additon in weight of the heavier R32 brakes.

im ot help there. when i sold my full R32 fronts including everything other than carriers, it came to about 43kg for postage iirc

[john_o]

cheers guys 

looks like approx 7.5kg per side (front) for going up to R32 which is HUGE !

Re GTI oem FRONTS: Whole assembly of disc plus calipers = 15.10 Kg each. (10.6 Kg for AP Racing's kit).

I've never weighed any rears.

Someone here linked to an audi forum where the weight difference were mentioned, i have it somewhere.

[Janner_Sy]

found it,

the weights for lower control arms are...

GTI/Ed30 = 4100 grams each

S3 /cupra= 2290 grams each

would presume the TT lower arms are neigh on exactly the same

danishmkvgti has just quoted

disc 312mm 7,75kg
caliper and carrier 5,5kg

Jake, what size are the AP?

[RedRobin]

AP Racing GTI: 10.6 kg - 330 x 28 mm

OEM GTI: 15.6 kg

Both measured on same scales at AP Racing in same session and witnessed by myself.

The 14.5 kg were from a TT-S form. Maybe the TT rotors weigh less . . .

I know this thread is old now..... but im going  upgrade brakes on my ed30.... going for audi s3 8v 2017 calipers with mk7 gti clubsport s 340mm x 30mm discs to save a bit of weight.... anyone run this set up.

Also what pads would one recommend for this application for fast road driving...and maybe a bit of tracking?
 Cheers.
