| Powertrix Competition Suspension components: Quality, R&D specifically for your Z32 Unfortunately, due to the how busy we have been with business, racing, R&D testing and current events, time has made it impossible to contribute to the forum lately. Due to the many emails and controversy, we felt is would be in the best interest to give this informative post to properly educate the general public on how Powertrix Competition Suspension components are designed, engineered, R&Ded, and tested to offer the highest quality available specifically for your Nissan Z32. Our purpose is to give the facts to the consumer so they can make the best educated choice for themselves and their vehicles. Please do not be confused by the rumor that Powertrix Suspension Components are anything near the products regularly sold on eBay. Our products are not manufactured by those same companies. As many know, there are machining companies overseas that are notorious for copying product. This is a reality that will never end and we expect the copying of out product to continue. Here are the pictures of some of our components. These are clearly not inferior components that others are referring to: 
Since we have complete control of our own development, design, and components used, (An essential power necessary to offer, create and evolve components of the very best quality for the specific application) this is a trait that we are proud of and that most companies do not and will probably never possess. We have further advanced and set our products apart from the companies offering like products. Our evolution is very evident with our products as we get valuable feedback from extensive R&Ding, real time in house and Authorized Vendor testing. So what makes our products, service, and support unique and unsurpassed? We here at Powertrix value and take into account the users opinions and suggestions. We also listen to much of the feedback given to us by the same long term daily driver and hardcore racers in regards to our components and apply them in the adjustments and upgrades that they have requested. We hold the end users wants and needs in the highest regards and respect. This business attitude is one of our highest priorities. At the request of the users and an opportunity to advance the features of our product, our arms now include upgrades self contained, self lubricating Teflon ball joints that are wrapped in dust covers for longevity and protection. Our first generation arms had grease able zerk fitting ball joints that were a hassle to maintain or squeaked due to lack of lube and or failure to center the ball joint hinge. When the car is at rest on the ground, the ball joints should be centered so that they are not binding on either side and causing excess pressure. If any ball joint is binding and not allowed to naturally swivel as intended, it can cause noise and eventual pre mature wear on the joint. We provide installation instructions to help orient the joints correctly. 
We have also reduced the weight of the components by 15-18%. Compared to Japanese competitor components of the like quality (ie: Kazama, Nagiza, Cusco) aluminum tension rods, which we do not recommend on a street car, ours are only 0.4 lbs heavier. 0.4 pounds of additional weight is by far worth the trade off to have a much stronger over build component. Though many have stated that their competitors’ aluminum components have not failed, this decision was based on one experience we’ve seen through on track and repetitive testing of an aluminum tension rod that snapped at the bolt points where they connect to the lower control arm. We decided it was not worth the risk of putting the consumer in a potentially catastrophic situation. The rear camber arms now featured in chromolly and offer more adjustability. (Approximately up to 3 degrees of negative camber for the road and auto cross racers) The Powertrix suspension components are made of heat tempered forged steel or chrmolly. Aluminum products are not recommended, are not as strong, and are prone to bend and flex. These suspension components under go massive stress and entire weight transfer of the vehicle. A daily driven or street car is subjected to even more blunt or shock force due to street hazards and road conditions therefore we do not recommend the use of aluminum for these components. Our arms have been Drag and Track tested under the most rigorous scenarios at the road courses of Willow Springs, Button Willow and California Speedway Drag strip with several different adjustments and are used and trusted by all Major Twinturbo.net Forum Vendors for their personal and race prepped vehicles. (Specialty Z, Concept Z Performance, Z1 Motorsports, Mossy Nissan of California)” Midori Style Front Camber Arms Debate: There is a misconception that our front camber arms have unshielded ball bearings. This is another false statement. The ball bearing on out camber arms are shielded Nachi Ball bearings. They are of the highest quality Japanese ball bearing offered. They protect the bearings just as well as sealed bearings. Only in the case if one was to submerge the car up passed the upper camber arms in water would it be an issue. Also, the bearing does not spin in a constant motion like a wheel bearing. It moves less than a quarter of a turn. There is absolutely no question that the bearings are shielded. If they were unshielded, the actual ball bearings would be exposed and visible. (See pic) The only reason ball bearings are used for this application is to give the most free moving travel possible to allow the rest of the suspension to work at its fullest potential. We have had no issues with prematurely worn bushings with the several hundreds of sets installed in the past 2 1/2 years including the severe duty vehicles that are both daily driven and tracked several times a month. We have been informed of only one recent issue posted on this forum with one set of arms. Unfortunately the consumer never contacted us. If we had been aware of his isolated issue, we would by policy and 100% support of our own product replaced the component in question and reacquired the component for inspection to determine the issue. Here is how you can tell you are getting genuine POWERTRIX components. All components are clearly labeled with our trademark and include installation are proper care information. 
Our Front Camber Arms are specifically designed for the characteristics and handling of the Z32. They are simply the best, meticulously engineered adjustable front camber arm on the market. How are the POWERTRIX Front Camber arms designed, engineered, and tested to be the highest quality available on the market? 
1. We use only the authentic Nachi Japanese shielded bearings. Other cheap imitations sold on EBay have inexpensive, low quality bearings that do not offer smooth operation and will result in a shorter life span. 2. They are also specifically made for the Z32 as it has an extra offset (Length “A” represented in RED) so the securing perches do not get damaged by regular suspension travel. The original style Midori/TBO arm was designed for and R32 Skyline. This offset is essential for proper suspension travel especially under extreme and track conditions. Even the stock A arm has this “dimple” or clearance built in to its design for regular suspension travel. There are other arms offered that do not have this correct offset and is the improper component to install on a Z32. Without this offset, the adjusting collars can be damaged causing total failure of the arms: [[ http://www.twinturbo.net/net/viewmsg.aspx?forum=general&msg_id=1199574&words=midori ] ]
[[ http://www.twinturbo.net/net/viewmsg.aspx?forum=general&msg_id=1199072&words=midori ] ] 3. Powertrix ensures that distances/lengths (“B” represented in BLUE and “C” represented in GREEN are of factory tolerances.) Improper sizing can cause fitment issues. Too large of the length will cause improper fitment or non-fitment and too small of the length causes loose fitment between the stock suspension brackets which will result in vibration and undesirable movement of the arms. “B”>”C”. “B” and “C” are not equal. Here are more pictures for reference:

 Here are some pics of our car for reference of right height and proper camber arm offset in reference to the suspension bracket. Note: There is a make shift “fix” for arms that do not have the proper offset. They require the use of larger bump stops to limit suspension travel. Limiting suspension travel in our opinion is not the proper solution and goes against the reasoning for the use of these suspension parts and their components. Allowing the spring and strut network to operate freely and independently with the least amount of resistance optimizes the use of the complete suspension geometry. It is also our opinion that modifying another component to insure that the component in question does become damaged or does not damage anything else is easily avoided by installing a front camber arm that has the proper offset.
