Vw to porsche boxter brake upgrade parts list & future DIY

Ready to race!
Found calipers on ebay for $170 each side.

Apikol sells brackets for $240 which is absurd

yes it's alot.unfortunately no one else makes them to keep the bracket price under control. but you can still find used brackets online from ppl parting out their kit.

if your getting these off of Ebay used. get all the maintenance items in my list. also get new dust seals. you don't want them leaking on the car.

wheel spacers, & porsche vibration dampers arrived today.
Hit a little snag though. While checking the Perf Diesel brackets I found that the bolts supplied from apikol dont match up. So i ponied up the dough and bought the apikol brackets. If anyone wants the Perf Diesel brackets for a side project or feel like figuring out the bolts required let me know

piston size/area



1. stock front caliper:


Golf/GTI - Ate FN3 54 mm caliper: 2290 mm²

S3/R32/R - FNRG 57 mm: 2552 mm²



2. aftermarket - proper match:


Boxster: 40 mm + 36 mm > 1257 mm² + 1018 mm² = 2275 mm²

Brembo GT caliper A: 40 mm + 36 mm > 1257 mm² + 1018 mm² = 2275 mm²

Stoptech ST-40: 38 mm + 34 mm > 908 mm² + 1134 mm² = 2043 mm²




3. aftermarket - poor match:


Forge: 707 mm² + 1046 mm² + 1164 mm² = 2917 mm²

Q7/Touareg/Cayenne (three variants):

34/36/38 mm : 907.920 + 1017.876 + 1134.115 = ~ 3060 mm²
32/36/38 mm : 804.248 + 1017.876 + 1134.115 = ~ 2956 mm²
30/34/38 mm : 706.858 + 907.920 + 1134.115 = ~ 2749 mm²



4. master cylinder diameter:

- 22,22 mm > 388 mm² (Mk.V GTI)
- 23,81 mm > 445 mm² (Mk.V R32, Mk.VI GTI, Golf R)
- 25,40 mm > 507 mm² (RS3 + TT-RS)



ps
If you know the piston diameter: Pi * radius² = area

Will do...Nice work on the calc's BTW....The Brembo's feel perfectly balanced regarding Bias, and this pretty much verifies it..

AWESOME!
Great info. Keep this updated and once a "semi complete" list is made Ill put it in my OP to make it easier to figure out the total area for each kit.
Install was delayed due to my friend with a garage to use had the flu so I wasnt able to go there and install this. Hoping for this weekend
