2004-2011 Mazda Rx8 Front Caliper Upgrade Kit

*This kit must use the Rx8 front sport rotor*

*This kit does not include brake pads. With hundreds of available pad compounds, we recommend researching and ordering your brake pads from a retailer. Pad type- .80” 7420*

Included-

•Wilwood Superlite 4 piston calipers

•Custom front stainless steel brake lines

•CNC machined adapter brackets and hardware.

Why a caliper upgrade? Why not a complete big brake kit?

*Economically priced vs. typical "BBKs" $1800.00+*

The most inexpensive Rx8 unsprung weight reduction on the market.

OEM floating caliper assembly weight-  11 lbs

Superlite caliper + adapter bracket weight- 4.95 lbs

Over 12 lbs of total unsprung weight reduction!!!

Upgrading to a larger 2 piece rotor will show minor improvements compared to the caliper upgrade. 2 piece rotors are approximately 2-3 lbs lighter than OEM and cost $700.00+ compared to $20.00 OEM centric rotors. When it comes time to replace the disc on the 2 piece rotor, the cost will still be upwards of $400. That money is better spent elsewhere for most applications.

The caliper upgrade kit is designed around the Front Mazda Rx8 SPORT rotor. At 12.7" diameter, the rotor is sized sufficiently for competition use.

• Superlite calipers utilize a quick change brake pad design for track-side modularity.

• Superlite calipers house THICK brake pads at .63" for drastically extended pad life.

• Decreased brake fluid temperatures due to the Superlite calipers large aluminum composition.

• Fixed caliper design eliminates additional moving parts and potential failures found with floating calipers under extreme temperatures.

• 9% increased front braking force. The added front braking force is optimal when utilizing aggressive 200tw, R-comp, and slicks which shift increased mass to the front axle.

• The caliper adapter brackets were engineered and FEA simulated to withstand infinite braking cycle loads of 1650 foot pounds of torque. In other words, they will never fail.

PLEASE NOTE-

Will fit 17” wheel barrels

2.25” of clearance is needed between the rotor face and the backside of the wheel spokes.
