BT Ventilated Caliper Racing Pistons
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. BrakeTech 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 conditions

Awsome Suit!. Top notch quality, one of the best suits that I've own by far, true to size & all the paddings where it should be!., very comfortable even with a tech air 5 plasma in it. I'd definitely recommend!! HHR customers service was also very awesome. Looking forward to more purchases in the near future..
These guys were great to work with, responded fast, shipped item quickly and I will 100% be ordering more stuff with them in the near future!
Great customer service and communication
Worth the money! Makes it easier to hit top speed than regular standard throttle tube! I have a 2011 and 2025 S1K and the Alpha throttle feels almost similar to the new 2025 quick throttle.
