BlackTrax Performance

BlackTrax Performance is happy to announce our exclusive partnership with Kingpin Machined Honda S2000 spherical suspension bearings used for competition level racing as well as those looking to get the most out of their suspension system. A two-year product development process provides you with the highest level of U.S. designed and manufactured spherical suspension components. BlackTrax Performance is now the exclusive install and service specialist for the S2000.


History
Some may recognize Kingpin Machines products and branding on some of the nation’s fastest pro level Honda drag cars as well as a handful of road race cars. In 2008, BlackTrax sponsored Honda Challenge driver Graham Downey needed to source replacement sphericals on his stock K24 swapped EK Civic (utilizing EG front subframe). After careful research he found Chris Brinson of Kingpin Machine, Chris’s meticulous (almost OCD like) attention to detail separates his product from the rest. Downey and his Kingpin sphericals laid down the law in 2008, 2009 & 2010 as the three-peat N.A.S.A Honda Challenge H1 National Champion. Now 6 years later, we’re still running on the exact same set of spherical bearings with no play in ANY of the bearings. This chassis has since logged over thousands of racing hours, HPDE’s and time attack events. None of the spherical bearings come with dust boots. That said, Kingpin’s design and tightly held manufacturing tolerances prove that dust boots are not necessary to control the wear on high quality sphericals manufactured by companies who build aircraft and milspec grade bearings such as Aurora and New Hampshire Ball Bearings. And for this reason, BlackTrax commissioned Kingpin Machine to develop the first custom S2000 set in late 2012.

Quality
Each and every sleeve is blueprinted to their specific control arm bore since the OEM specified tolerance for the bores are too wide for proper bearing operation. This level of quality and craftsmanship requires state of the art equipment and a one off manufacturing approach. Consequently, these are highly cumbersome and costly to build. In order to maintain the superior level of quality control, We (Kingpin and BlackTrax) are collectively sharing blueprint and machining specifications in order for BlackTrax to carry out consistent results giving you the benefits of longer lasting durable bearings that will significantly improve stability, additional grip, driver confidence and faster lap times and/or quarter mile times.

Anyone interested in upgrading to Pro Comp sphericals can ship their control arms to BlackTrax Performance to get the best quality sphericals on the market to date and will receive the following services:

• Disassemble, Shot Peen & Cleaning-Bores are Machined/Honed to Spec.
• Press & Weld Precision Machined 4140HT Steel Bearing Sleeves
• Control Arms Coated with Black Suspension Paint (Zinc coating available at an additional cost)
• U.S. Manufactured, Aurora and/or New Hampshire Ball Bearing bearings are pressed in, then Secured by Loctite 609 and a C-clip-Re-pack/Grease Ball Joints
• Quality Test & Return Shipping

Words From Kingpin Machine:
It is true that manufacturing quality products from properly graded, US sourced metal and utilizing the best available US produced bearings is more expensive. But it is not only the right thing to do, it ensures that you are running the safest and best performing parts available on the market.

-Only Aurora Performance Racing Series and/or the New Hampshire Ball Bearing Racing Series lines of bearings are used.

-Our no compromise approach extends to material choice as well. We machine our bearing sleeves from 4140 HT (Heat Treated) steel and the vast majority of our spacers from 7075 Aluminum. These materials are more expensive than the standard mild steel and 6061 AL but the superior surface finish, additional strength and hardness are well worth the added expense.

Installing control arms equipped with our spherical bearings provides a number of benefits:

• Lack of deflection allows reduced static camber requirements, thus minimizing uneven tire wear and increasing traction.
• Improved steering feel and precision as steering input is directly translated into wheel movement.
• Reduction/elimination of dynamic toe change, which along with handling benefits can also provide stability under braking.
• Elimination of high breakaway torque requirement increases traction; allowing the tire to stay in closer contact with the track surface.

All of our parts are designed, machined and tested right here in the United States.


Testing
We have 6 years of testing on various Honda applications using the same bearing and sleeve construction now being applied and currently used on the S2000 chassis. The S2000 Pro Comp Sphericals are being tested on five S2000's.

More from Kingpin machine:
Stock control arms and suspension housings simply are not produced with the same level of precision as our products. There is no reason for auto makers to hold to exacting tolerances when using stock compliant rubber bushings. We produce our bearing sleeves in a range of outside diameters and the proper sleeve is chosen to produce just the right amount of interference when pressed into the control arm.

Pressing bushings out of control arms is generally a dangerous process that requires specialized equipment. We have already created fixtures and dies to hold suspension components in place while applying the immense pressure needed to press out stock bushings. We have the proper assembly tools such as a hydraulic-electric press, an arbor press, welding tools, retaining tools and products etc. and just as importantly the experience to do the job right.


BlackTrax Performance is committed to maintaining continuous improvement of Kingpin Machine sphericals. We will continue to capture data from each control arm you send to us for precision installation and services.

We're throwing around the idea of organizing a group buy and want to gauge the level of interest. To the people who are currently using our sphericals and to those interested, we welcome your feedback!

I heard fantastic things about their performance on track last month. How's the street ride quality with these? Keep me posted on group buy info if that ever develops (PM is fine).

JUSTINTHECOASTIE

very interesting

BlackTrax Performance

We noticed, no noticeable difference in street ride quality over OEM rubber bushings. Engine or transmission mounts are subjected to RPM frequencies. Control arm bushings, not so much. By the time the frequencies travel down the the control arms, vibration/harmonics become negligible..at least to the human touch/senses.

What you do notice is the added control arm articulation. The bushing bind you feel, is now eliminated.

So, whats the price!?

bgoetz

^^^^my level of interest certainly depends on this key detail

They will be pricey for sure. You can go look on their site now at some of the similar parts they already do for other cars. For instance the LCA for a DC2 is listed at $540 and has one less bearing than the s2k.

Will they offer the ability to only do certain bushings and not others? Such as can I get their complaince bushing for the front lower arm but leave the others stock?

BlackTrax Performance

Currently we've been assembling full packages (8 control arms). If we were to break these down, assume by the pair..ie. FLCA L & R - includes 2x Compliance, 2x Shock and 2x Inner Forward

Here are a couple of pictures after shotpeen and after we've honed the bores, fit the sleeves, TIG, paint and fit the Aurora bearings.

Someone asked a good question: Are the 4140 housings plated or raw?
Yes, each and every 4140 bearing sleeve is zinc plated.
