At what point does the RC-F need /could use these aftermarket pieces?

I needed rear camber arms to get back into spec after coilovers. The front wasn't exactly in spec. The uppers will help get the front end in spec. I really don't see the need for most of the parts unless you want to run some crazy negative camber

It really depends on what you are looking to do with your build, replacing the factory arms with our Pro Arms will give you the adjustability to fine tune your alignment and the solid pillow bushings will increase the control and stability vs the factory arms with rubber bushings. Another thing that is nice about our arms is the new Delta Ring alignment technique we just came up with which drastically minimizes the toe change when the car is raised and lowered which is extremely noticeable on cars with air suspension thus giving you a nearly perfect alignment at any ride height.
In the video below is our Lexus Is300h demonstrating our Delta Ring system, below is the first part of the video I translated to english.


T-Demand presents a new design and alignment adjustment technique called “Delta Ring” to accompany our “T-Demand Pro Arm Series”

This new alignment adjustment is to correct and control the fluctuations of the camber, caster, and toe of air suspension vehicles. Thus, reducing the wear of the tires over time and better control of vehicle traveling on any height setting.

Cars with air suspensions have a common issue of a changing alignment from raising and lowing the height. One of the many reasons why the alignment changes after adjustment is because the arm of both sides of the vehicle are not completely equal in values or symmetrical, but have slight differences in length. Thus, causing the car to drive differently at each height setting and “not traveling straight”, “unstable driving” or “having difficulty of handling”.

T-Demand has developed an arm system that can achieve the correct balance and symmetry between both the left and right arm lengths. The measurement of both left and right arms are also determined by not only rulers but also the number of rotations and revolutions. Therefore, having the most accurate and perfect alignment is vital for the symmetry between the left and the right arms.

During the alignment process we do not want to make large changes the length of the arms but only small values of calibration to correct “pigeon toe effect”, when the vehicle is adjusting heights.

For example, in our video demonstration of our T-Demand Complete Lexus IS, we can move the vehicle height up and down freely with the air suspension with The Delta Ring system set whereas with a normal alignment it is only possible to have the correct alignment at a set drive height.

When a vehicle has wider tires on the wheels and tucking in the fenders, one must be cautious of the tire clearance and tires hitting under the fender. Thus, minimum camber and measurements must be observed to avoid inner fender damage. After Delta Ring alignment, the wheels and tires will sink into the fenders with not too much stress and angle on the camber, toe, and caster.

This technique is called “Delta Ring” produced by T-Demand. An alignment method that allows us to fully control and achieve the perfect alignment numbers for any ride height.

For those in immediate need, I had a custom set made using SPC replaceable/adjustable ball joints. They are for sale in the RC for sale section.
