The HB PRO5
The All-New HB PRO5 is Here
Taking the HB PRO5 global as a development chassis and regularly racing against the world's best drivers gives Team HB the opportunity to give the PRO5 a real trial by fire. Updates to the car are tested in the most strenuous conditions to give HB drivers a real comparison to other cars and against the most unrelenting competition. Week by week, new changes are rolled out to the Team HB drivers so they can make consistent updates as they battle door-to-door with the best of the best. This all adds up to the HB PRO5 being a completely new and totally fresh design, full of innovation and brand new parts.
At first glance, the PRO5 is a standard double-deck touring car, however it's only when you look closely that you notice the fine new details and all-new parts. The main chassis is cut from 2.25mm woven carbon fiber, fitted with 7075 aluminium bulkheads. The design of the motor and layshaft mount is all new, for better weight distribution and efficiency. A 2mm woven carbon fiber upper deck sits on top of the aluminum bulkheads, sandwiching the drivetrain in place. A high-efficiency drive belt and alloy pulleys are standard equipment on the PRO5, and large 40-tooth pulleys at each end surround the new extra-large rear gear diff and the front solid spool. DCJ-style front universals and standard rear universals are driven by alloy diff outdrives for a supremely low rotating weight, and clamp-style hex adapters are securely fitted to the drive axles. The front hex adapters have an extra-thin narrow profile, allowing you to easily alter the front track width for an optimized steering feel for your driving style.
The suspenion features a huge number of updates and is full of completly new parts, including the thick woven carbon fiber shock towers, threaded aluminium big bore shocks and totally new suspension arms. New easy-access ball cups mean you can change roll centers quickly using shims, and of course a complete set of turnbuckles are fitted as standard equipment. With ultra-precise steering a requirement for all touring car racers, the PRO5 is fitted with reliable bearing-supported bellcrank steering for extra-smooth action, using alloy arms for strength and durability. The Ackermann setting is easily adjustable using orange-anodized shims, and the steering turnbuckles connect to woven lightweight carbon fiber steering arms. The PRO5 also features a woven carbon fiber floating servo mount and floating battery mount to allow the chassis to flex properly for consistent handling in all conditions.
Rounding out the HB PRO5 are adjustable front and rear sway bars, alloy ball bearing belt tensioner, integrated antenna mounting, fine pitch body post adjustments, and a super slick black and carbon fiber look with orange aluminum color accents throughout the car.
The HB PRO5 is purpose-built from the ground up to be competitive for club racers and international racing stars, right from the start.
Interview about the HB PRO5 with JJ Wang
JJ is rapidly developing into one of the fastest touring car racers in the world, and has featured on Team HB since 2013.
When did you first drive the car and what involvement have you had with its development?
I first drove the PRO5 couple in late 2014, and the first major race for me was the ISTC worlds. I am happy to be involved in the process of making the PRO5, with the main designer Hara-tune, Hiro and Andy.
What do you think are the PRO5's best features?
I think the one feature that makes the car unique is our infinite selections of camber links, this makes it easier for us to make fine adjustments to the car. The PRO5 is designed so precisely that we not only focused on the geometry of the car, but we also focused on all the small details that make this car so flawless. Also, it fits both carpet and asphalt racing because the car has quickness and stability at the same time. I believe the PRO5 can be equally fast on both surfaces.
The PRO5 performs well when driven by pro drivers like you, but do you think it will also be good for club racers?
One thing for sure is that the PRO5 fits all drivers, the car is so easy to drive right out of the box and we made sure the car is both competitive and fun to drive.
