Pistons fitted sizes are opposed to ensure extremely high, consistent levels of friction under braking, and even help with pad wear.

POWERVANE Brake discs 355mm x 32mm [Rotors]:

Powervane Racing Rotors are probably the best Rotors in the Motorsport Industry today. The curved Vanes are angled to use the rotor’s deflection of rotation to enhance cooling performance making them side specific.

Powervane Racing Rotors are manufactured to ISO 9000 standards. Each casting of our Rotors is subjected to stringent quality controls.

This includes sample testing and random batch testing to avoid potential problems due to internal and external blowholes, cold shots, sand inclusions and other defects to provide the highest quality.

POWERVANE Rotor Features:

• A unique composition of dampened iron casting for optimum rotor wear, balance & reliability.
• Excellent cooling characteristics.
• 40% Lighter than the original manufacturer’s designs.
• Angled curved vanes direction of rotation L/H & R/H to further enhance performance.
• Cast iron construction, 30000 psi damped grey.
• Supplied to international rally car builders and formula racing teams.
• Suitable for vehicles where power exceeds 500bhp and 1000 degrees.
• Vanes serve to reinforce the rotor and guard against warping.
• Exclusive vane design disperses heat & gases faster, whilst maintaining a clean pad surface.
• Brake fade virtually eliminated.

Powervane Rotors offer the ultimate in disc brake technology, internally vented with curved vanes, designed not to deteriorate, warp or crack under extreme braking conditions. This unique design virtually eliminates brake fade, each disc has 6 slotted gas vents. The centre billet aluminium mounting top hat bell is hard anodised to increase strength and is secured by 12 stress-relieved, high tensile, cap head plated bolts, with heat-resistant locking cleave nuts.
