Hi all, been in the market for a 6-piston track BBK on my '16 GTI PP to fit under 17" wheels and also wanting to stay economical. Plenty of options out there between StopTech, AP Racing, APR, Racingline, etc. but I've always seen stuff about ProdigyWerks for the value they provide for their BBKs. Currently they have their own 330x32 and 356x32 2-piece options for the Mk7 platform in 4/6 pistons as well as a race series calipers (that was an expensive kit) but interesting enough they have a 6-piston retrofit kit (FS6 caliper) to be able to use on the MK7 stock 340x30 rotors for only $900. Even better is that it is the same caliper used for retrofit as well as for their own rotors (with a mounting bracket) so very flexible in fitment/use.
When I reached out about heavy track usage, they recommended I get the FS6 T1R caliper which is the same caliper with track modifications including titanium vented pistons, anti-knockback springs and internal seals to cut overall weight and handle heat better. The cool thing is that they offer this caliper also in a stock 340x30 retrofit for the Mk7 which isn't explicitly advertised on the website (typically shown starting in the 356x32 size but does say 330x32 in the info page). Their T1R kit also is advertised with a brake ducting set but they are saying due to fitment issues, this is not ready nor possibly will ever be ready for this platform (and with that they cannot sell any of that ducting separate from the rotors as a standalone kit obviously).

Therefore, the pricing for this FS6 T1R race caliper is very compelling for a Mk7 PP 340x30 retrofit and I will be purchasing this to use on my '16 GTI with 17" wheels early next year to replace my Macan 4-pot Brembos that are great but not going to be heavy track viable. Here's the price breakdown and Q&A from Prodigywerks summarized:
Hopefully this is a good kit that folks can use to just attach to their PP setup at a good price for track, I'll be ordering one to be ready for track season next year with these assuming the aftermarket pads are readily available (will update before I purchase). Plan would be to get the R93 performance pads for street/autoX then a race/endurance pad for the track. Thoughts/comments?
Edit 12/15: Updated the thread with some other info, the retrofit kit actually requires their mounting bracket conversion so bumps up price a bit.

Here's the price breakdown and Q&A from Prodigywerks summarized:
- Differences between FS6 caliper and FS6 T1R track caliper:
- Same forged construction and shape/size, same rigidity and fitment
- Hydro vented titanium vs aluminum vented pistons, internal dust seals vs external boots, 6lb knockback springs with T1R, ~1lb less per corner (2.8kg = 6.3lb for T1R)
- Estimated Pricing as of 12/15/21
- $895 + $175 ship - FS6 bolt-on caliper for 340x30mm rotors (includes mounting brackets, not as much for track use, available today)
- $1295 + $175 ship - FS6 T1R bolt-on caliper for 340x30mm rotors (includes mounting brackets, track use, available today)
- $2195 + $345 ship - FS6 T1R with their 2-piece 330x32 rotors (ETA March 2022 due to rotor shortages, these rotors look great though with cheap replacement rings and easy to move to 356mm)
- $2395 + $345 ship - FS6 T1R with their 2-piece 356x32 rotors (available by end of Dec 2021, fits under Apex SM-10 17x9")
- Pad Shapes (matches AP Racing 7040 Caliper)
- D61 - Bolt-on kit pad shape for use with stock 340x30 rotor (AP Racing CP7040D61/Pagid 4346, depth of 58mm but known as D61, same pad for larger PW 380/410mm rotors)
- D54 - Pad shape for their 2-piece 330/356x32 rotors (AP Racing CP7040D54/CP9040D54, depth of 54mm, these seem to be harder to find)
- Brake Pads:
- They sell a street and performance pad, they said their performance pad is a street/track hybrid and to buy the track pad of choice as needed for heavy track use
- Street pad is semi-metallic (500c), R93 performance pad is carbon non-asbestos (700c)
- D54 R93 performance pad - $149, D61 R93 performance pad $159, their street pads are $50 less
- Wheel fitment (all focused on 6-piston FS6):

- I reached out to Apex to see if the 356x32 kit can fit under their SM-10 17x8.5" or 17x9" wheels, will report back:
- Apex Mk7 Wheel/BBK Fitment Guide: https://support.apexraceparts.com/h...-Golf-GTI-and-Golf-R-Wheel-Tire-Fitment-Guide
- Confirmed that the FS6 356x32mm 6-pot BBK fits under the Apex SM-10 17x9" et 42 wheels without any spacers -> This is the way
Hopefully this is a good kit that folks can use to just attach to their PP setup at a good price for track, I'll be ordering one to be ready for track season next year with these assuming the aftermarket pads are readily available (will update before I purchase).
