Even more brake cooling

I have decided to try these Dixcel Dual Active Ventilation (DAV) brake discs as my previous discs have warped and haven't been quite right even after machining. The DAV discs allow the cooling air to enter the vents from both the inside and outside of the disc hat. More information on how they work can be found at:

The Dixcel DAV however are the heaviest discs out of all that I have had the opportunity to weigh:

Dixcel DAV FS: ~9.5 kg
DBA 4000: ~8 kg
DBA 5000: ~7.5 kg

X3E Motorsport:  ~7.5 kg
Project μ SCR-Pro: ~7 kg

It is hoped that these Dixcels will last much longer in combination with the brake ducting that was recently installed.

Thanks to Silas for a helping hand in the garage.
