Personally I would fit a 4pot Brembo 312mm systems...way better than the 340mm PP brakes...& way lighter....

BUT if you cannot afford the above & can get the PP system cheap, I suggest you fit the 340mm size 1kg each lighter Clubsport discs...

^ I was looking into the Rotorlab kits myself, but it seems that the move from steel (MK6) to thicker aluminum knuckles on our MK7's require some work to make them fit. Apparently you have to file down the aluminum knuckles so that the caliper sits centered over the rotor. Up to you if you feel you're confident enough to perform that modification. New knuckles are in the $400 area IIRC.

Anyone have one of the Rotor Labs kits? Price is right. I saw the 17Z kit is said to fit the MK7 but the 18Z only fits the prior generation VWs which is saddening since it appears to be a much better kit for a marginal increase in price.

How much better is the 17Z kit than the stock Golf R brakes? Would a pad and fluid upgrade be similar to the 17Z kit or no? I'm starting to become a better driver at the track and brakes have certainly become an issue. Had to cut my last two sessions short because the brakes were getting a bit squishy.

It won't work on our cars. Might as well do the TTRS calipers and get brackets so you can use 345mm rotors. That's my plan at least.

The text on their site says they can modify the tab for you. Is that all that's required or is there more that needs to be done? Here's the text on their site.

BIG NOTE HERE: for VW owners, the 17Z calipers MUST have the tab modification in order to make the caliper sit dead center over the rotor. This is an additional but minor cost. Please contact us for details.

You have to modify your knuckle as well unless you have steel knuckles like a golf.

Spoke with Rob for a couple of hours when I was looking at their 17z/18z kits.
If your Golf has steel knuckles the 17z and 18z kits will fit easily. The calipers will still need the tab modification though.
The 17z/18z can be made to work with the aluminum knuckles if you file/mill down the knuckle where the calipers mount to the knuckle. You have to take off something like 1/2" of material though. Replacement aluminum knuckles are $375 and $450 depending on the side.

Way easier to buy the 986 front calipers. Apikol sells brand new calipers. Or you can refurb a set for cheaper.

I did a conversion to PP brakes. Below is information concerning from my research and experience installing.

I think you may be a tad low on your $800 estimate for PP brakes.

I first just did the fronts, easy straight forward job.

For the rears, I ran into some surprises. To remove and install the new splash shield you need to remove the wheel bearing assembly. The splash shield is not a C shape like in the front, but a hole inside the wheel bearing assembly. Have a large breaker bar as the torque to put the wheel bearing back on is 150 ft lbs plus 180°. You will need a M14 and M18 triple squares.

The brake lines need to be replaced as the banjo fitting is larger on the PP brakes. Brake Hose Line - 5QM-611-775-D (5Q0-611-775-H alternate, should work), the 5QM part has a list price of $73 each.
The alternate come out to be around $24 each so I just got some Stoptech shielded lines.

Also on the rear rotor I found that P/N 1K0615601N worked and found significantly cheaper.

I did the front PP first and did not note any brake bias.

I did the rears as I found the vented rotors look pretty cool and the standard rear non-vented rotors look small compared to the PP front rotor size.

Look for used PP calipers and carrier will save you significantly. I happen to have a set for sale in the for sale section.

These are the sizes for references:

MK7 GTI with Performance Package.

Power assisted, dual circuit, 340mm vented front discs and 307mm
vented rear discs

MK7 GTI

Power assisted, dual circuit, 312 mm vented front discs and 272 mm
solid rear discs

MK7 TDI

Power assisted, dual circuit, 288mm vented front discs and 254mm solid
rear discs

MK7 1.8

800$ was part for part, including used calipers (which could be repainted). I did my research, just not everything brand spankin new

Take a good look at the 4-pot Brembo option. Calipers are from a 986 Boxster.
Comes out to about the same price as the PP upgrade, but weighs less and has better performance.
