Project Nissan 370Z- Suspension Basics
By Mike Kojima
In the first segment of Project 370Z we worked with AEM to evaluate the awesome ETI cold air intake. Since our car is going to be focused on streetable track performance, we next turned our attention to the suspension. The first and most critical parts of any track worthy suspension build are the swaybars, dampers and springs.
|The Whiteline front bar (part number BNF41Z) has precise bends, a durable powdercoated finish, billet aluminum bar locks and low compliance urethane bushings.|
|The rear bar (part number BNR37Z) has clamp on urethane bar locks and hard urethane bushings.|
We decided to use Whiteline adjustable antisway bars for project 370Z. We are strong believers that swaybars for a street/track car have to be adjustable. Conditions change from street to track and from track to track. Your wheel tire stagger and combo are probably different from what your coilovers were developed on. Your driving style is most likely different than that of the drivers/engineers that developed your suspension calibration. Having adjustment in your roll stiffness via the bars can really help you dial in your car.
|The front Whiteline bar is the same diameter as stock but solid instead of hollow like the stock bar. It is two way adjustable. The rear bar is 1mm larger than stock and is three way adjustable.|
The Whiteline bars are really high quality; with an excellent fit and a glossy rust resistant powdercoated finish. Unlike other aftermarket bars, we don’t have to worry about bind and interference with other chassis parts with the well-designed Whiteline parts. The Whiteline bars pivot on hard polyurethane bushings to reduce compliance over the stock soft rubber, making the bars more effective.
|The rear bar uses Whiteline’s heavy duty adjustable end links. The adjustment allows you to remove all preload from the bars, important when corner weighting. It also allows you to adjust the length to minimize angularity when adjusting the bar in different holes.|
The Whiteline bars are two-way adjustable in the front and 3-way adjustable in the rear. The front bar is two-way adjustable due to the short length of the stock end links. Having more adjustment would risk bind due to the excessive angularity of the short link in the tight space. The rear bar uses Whiteline’s heavy duty adjustable end links. These end links are much stronger than stock and are adjustable to eliminate preload and to get the most favorable angularity when adjusting the bars.
