Nissan GT-R R35 390mm Front Rotor Conversion Spacer Set – 6mm (2009–2011 CBA)

The 390mm Rotor Conversion Spacer Set lets 2009–2011 (CBA) Nissan GT-R R35 owners run the larger 390 mm front brake discs from the 2012+ GT-R. The 6 mm spacers move the factory front Brembo calipers outward so they clear the bigger discs, giving more braking leverage and better heat capacity without changing the calipers.

What’s Included

• 2 × 6 mm front caliper spacers (left and right)

Key Features

• 380 mm to 390 mm upgrade: fits the 2012+ GT-R front discs to 2009–2011 cars
• 6 mm thickness: the exact offset needed for the factory calipers to clear the 390 mm discs
• Keeps the factory Brembo calipers, so there’s no need for a big brake kit
• No extra bolts needed: installs with the factory caliper bolts
• Precision machined for correct caliper alignment on the disc
• Lightweight cut-out design for strength with less weight

Why Upgrade to 390 mm Front Discs?
A larger disc gives the caliper more leverage, so the car stops harder for the same pedal pressure. It also holds more heat before fading, which helps on fast road runs, track days and roll racing. It also opens up the full range of 2012+ GT-R front discs and brake kits for older cars.

Fitment
Nissan GT-R R35 2009–2011 (CBA). Front axle only, because the rear discs are the same size on all years. Not needed on 2012+ GT-Rs, which already use 390 mm front discs.

• PowerStop Track Day Brake Kit (Steel Front & Rear Rotors + Track Day Pads): for track days and roll racing

Do I need new calipers?
No. The spacers work with the factory front Brembo calipers.

Do I need longer bolts?
No. The spacers install with the factory caliper bolts.
