Rear brake upgrade advice.

[jedi-knight83]

So I've just bought some mk7 golf R brakes for the front.

Is it a good idea to upgrade the rears? Is it necessary? Or OK to carry on with the standard GTI rears?

Just wondering about the balance. Or do people only really do it for visual reasons.

I'm just running TTS front brakes and standard rears at present, all seems ok but I'm always on the look out for an S3 rear set up.

I'm running a BBK and OEM GTI rears.... No bother.

bloody f1.8 prime lenses and their soft focus really irks me!!!

ANyway 4 pots on the back are for show rather than go most of the case

S3 calipers are all that you actually NEED combined with a decent ttrs setup up front
340/345mm on a ttrs caliper with the aks adaptors and whatever the s3 is (i forget is it 303 or 310 or 308 blah blah) will give you a lovely pedal and good even braking force which will hunker the car down into the ground.

Issue is after this master cylinder and long pedal
you'll need 6/8 pots up front to compliment a 4 pot rear. That's a lot of fluid
and a lot of cost
Once you go above the ttrs / s3 - front / rear setup the improvement tails off very quickly at great expense for that extra 5%.
even for most people on the track or in light competitions its not necessary.

notice how nearly all of the multi piston rear setups are on show cars that never go more than 30...

As long as your GTI has the same master-cylinder as the R32 (like mine has) you can have a 6 pot at the front and the R32/S3 brakes at the rear (310 mm vented discs instead of 282/286 mm solid discs) with great pedal feel. My Brembos 18Z at the front were cheaper to properly setup and I don't need wheel spacer with OZ Ultraleggeras. Just another option when considering brake upgrades.

Do you have any part numbers to differentiate between the two different master cylinders?

It's easy to check. The smaller has 22 written in the part and the bigger has 23. I could easily see that my GT Sport has a 22 and my Ed. 30 has a 23.

Hi @skuncan67 Duncan, I wish they were mine but that was just a picture I found when searching for something. I have standard brakes atm and don't think I'm going to be replacing them anytime soon. funds are way too low. If I were to do a brake upgrade then it would only be the four pot as I did with my last car and the rears I'd most likely leave oem. Sorry I couldn't help.
