Ok, here comes the time for my latest update >
Just finished instaling a new brake system, much more capable and lighter than my previous R32 brake system (wich served me exemplary on track). The new system is Ap Racing Pro 5000+ and was purchased from our colegue Stefan (Teff) about 2 month ago. The fun started when, trying to install the brakes I noticed they won't fit the S3 spindles wich have thicker legs than the OEm GTI ones. Because I didn't want to give up the S3 spindles (lower weight , lighter steering feel and increased comfort), I decided to design a new caliper carrier myself and find a CNC machine to execute it. The new carrier was different in 2 places than the original AP Racing one :
1) The new carrier needed to be lenghtened by 16mm in order to fit the S3 spindle
2) The new carrier needed to be filed on the lower side because it was touching the TT arm with the wheel turned to the max. ( I manually filed the old carrier to find out where it didn't hit the arm anymore)
I then made an Autocad drawing of the carrier and send it to our beloved colegue DaveB for manufacturing (the shop that makes the parts for Dave also makes parts for Red Bull racing F1). Unfortunately they made 2 mistakes on the new carriers wich I saw when I was with the car on the ramp ready for the install:
1) The pitch of the thread of the M12 bolts was 1.5 instead of 1.75 so I decided to make new bolts because it was faster than sending the carriers back. It was hard to find bolts with 1.75 pitch and allen key head but I fabricated some from a strong alloy (not so strong as the original Ap ones though)
2) The original carrier had a milling (cutting) that was there to clear the pad ears (probably the guys from the machining shop considered this useless or they forgot about it. I found a machine to make the cutting but afterwards the hard anodizing on that area was compromised so I found a high temperature paint spray wich I used to protect that area (not as good as anodizing but hopefully will protect the aluminium carrier.
PS : I acomplished all these in one day only with the help of my friend Teff wich had the patience to carry me around town the whole day (my car was on the ramp and it took me the whole day to make the mods but succeded to install the brakes on the evening of the same day)
