I believe it was Rob I spoke with at Rotorlab and he said the only MK7 golf that's not needed modification was a plain 1.8T Golf which does use the same part numbers as the TDI for R/L knuckles.

Cool, way back when I spoke to him he asked me to go out and look at the knuckles on my car. I verified they were steel and not aluminum. I placed my order at that point.

Was thinking about the master cylinder issue last night. In the MK6 people did have to change their master cylinder (different piston sizes) but I haven't read anything about different pedal assemblies or different pushrod lengths.

Hopefully my brakes show up in the next month or so. I will order the GTI-PP/R master cylinder from a place that takes returns and have it on standby.

The offset is different than what he mentioned was ideal on the phone (78mm/79mm vs 80mm on the TDI), which in theory would mean taking off more or less material when they machine the tabs of the calipers. I've sent them an email with pics of all the measurements. Maybe it will help them get your set just right!

Also emailed USP motorsports to see about fitting the proper conical male end for the brake line to a set of MK7 TDI lines to retain stock mounting brackets. Always trying to keep things clean!

Edit: No dice from USP, they don't do "custom lines" at this time. Putting the fitting of one line to another is apparently very custom...

Ordered my kit last night! With all the measurements taken and talking with Rotorlab, I feel pretty confident these will fit just fine on the MK7 TDI's steel knuckles. The offset IS different (78mm vs 80mm), but it sounds like they take off enough for the widest offset and if you have less, you just use a spacer or two to get the caliper centered over the rotor.

I had just received an advertisement email yesterday as well from VWR with a kit they're coming out with...$2995 for the same thing. I just don't understand why these kits can go for double and triple what I just put down.

The lines, pads, fluid, and master cylinder will all be under $300 combined.

Sweet, I can't wait to get mine. So I may need a washer or two to center the caliper... I can definitely handle that. He advised me to order MK4 R32 brake lines, they have the proper conical male end. I will have to look see what the lengths are though. I've seen them go for ~$50 with random flash sales from the usual vendors, normally around $70 though which still isn't bad.

I have already ordered the Apikol 65-68mm rotor centering rings for $50 and Bosch Pads (2004 Touareg V6) for $65. I cannot wrap my head around the prices for some of the kits on offer.

Thanks for taking those measurements, I'll post when I find out if the lines are close enough in length to use.

The 345mm rotors with the 18z kit do not require centering rings, only the 17z kit rotors. I know you said you were getting the 17z to retain your 17" wheels though, just want to provide that info here for anyone else reading.

I found pads for $52 and free shipping on Amazon. They are Bosch Quietcast for an Audi Q7 (again, for the 345mm rotor 18z kit), you can't beat that! They are absolutely gigantic too, haha

The MK4 R32 (Caliper Conversion) lines at USP are what I got. I'll mock them into place when I get them to see how they'll line up in the existing support bracket that has two different mounting types. The MK7 only uses one of the two options on the bracket, so there could be a position that works out.

For reference, a TT-RS is 25.4mm with pushrod length of 1.75" (that's with the Brembo 4-piston calipers with 57mm pistons x4)
I just picked up part# 8V1611021B from the dealer (for GTI-R). It measures 25.4mm bore and pushrod of ~44mm which matches the TT-RS info unless I'm measuring the rod length incorrectly.

Nice, so maybe VAG "simplified" between the Mk6 and Mk7 and went down to just two master cylinder variations instead of 3.

If you don't mind my asking what did it end up running you for the new master cylinder?

After tax the cheapest I can find within a reasonable distance of where I live in Los Angeles is about $180. It's more than an hour south but I'm headed to San Diego on Saturday anyway and it's only about 5 minutes off of the interstate I'll already be on.

Didn't see your post before the most recent one. Quietcast are what I went with as well... with the front brakes looking to be well-sorted I wonder what can be done so the rear brakes don't look so silly in comparison.

A member over on golfmk7 is running GTI-PP rear brakes on his TDI... it was mentioned that they bolt on but required slightly longer brake lines. He had a couple sets made. I actually bought one of the extra sets although I'm not yet sure if I will use it. The PP rears also required rerouting the E-brake line, which is my only reservation. My thinking is similar to yours in that I want to use factory mounting locations and routing.

Used PP rear brakes are also not easy to come by, not much need to upgrade. Full brand new set runs about $1000, which is hard to swallow considering what the front kit costs from rotorlab. Speaking of which I should to give them a call tomorrow and ask what they have (or can suggest) for a rear setup.

The MC from my VW dealer was $155 +tax. No shipping because of local pickup. The dealer I go to has the best pricing when buying online, so that's what I do most of the time.
