But they’re still using problematic aluminum pistons – lightweight, yes, but also highly conductive in providing a huge heat path into the hydraulics

SP400 27mm Caliper Racing Piston kit.

Ventilated Caliper Racing Pistons are the state of the art design and will allow the brake system to maintain a cooler and stabil temperature.

Late model OE calipers have come a long way in terms of both performance and design. Far more rigid than their predecessors, the late generation examples from Brembo, Nissin, Sumitomo, Tokico and others provide ultra stiff and relatively lightweight designs have been instrumental in bringing braking performance to new levels.

But they’re still using problematic aluminum pistons – lightweight, yes, but also highly conductive in providing a huge heat path into the hydraulics. Spears Racing  is now addressing this with specially engineered ventilated stainless steel pistons of proprietary material that all but eliminates those shortcoming:

• Reducing thermal conductivity by 94%
• Dramatically improves piston retraction, reduces brake drag
• Increases top speed
• Eliminates fluid boil
• Improves release time for greater control exiting the apex
• Improves overall braking consistency under severe racing condition

Ventilated Caliper Racing Pistons are the state of the art design
