Hi Guys,
Well after three years of head scratching (and banging) we're ready to release the new Front Uprights. The first sets are already being shipped.
These peices join our new Rear Uprights and are also intended for use on the "100 Series" cars manufactured by or with the parts from the original Cape Advanced Vehicles.
Owners of post 100 s/n cars already have upgrades built in from Autofutura so these parts don't apply to you.
The new Front Uprights use the same CNC machined billet steel center as our Rear Uprights. The cooling holes lighten the part while reducing bearing and brake temperatures. The holes actually feed the inside of the brake rotor vents.
Also we've inclined the upper ball joint mount to give back about 5 degrees of ball joint angularity, needed for lower ride heights and larger (than 24" dia) tires.
The steering arm ratio is as stock however the pickup point has moved inwards to optimize Ackerman angles. This improves steering response on initial turn in and throughout the corner.
The Castor angle is zero in the upright and the kingpin angle runs through the axle center. Castor is dialed in by moving the upper control arms in their slots, you can get 4>6 degrees depending on how much weight and steering return to center you want.
The concentric kingpin angle reduces shimmy and bump steer in the steering wheel. This is a subtle effect as the bump steer is minimal at normal ride height, however the wheel will feel more direct and linear.
These are bolt in parts that use your existing A-arms, Ball Joints and Tie Rods. Of course the alignment will have to be re done. A nice weekend project. There is a core credit for your old parts so it doesn't hurt so bad.
Steel parts are about three times stronger than aluminum parts of equal weight, that's the nature of the metal. While our new Rear Uprights weigh the same as the stock castings, our new Front Uprights are about .5kg heavier each. While I hate putting any weight on a car, a couple of pounds total for parts three times the strength is worth it.
Plus they look cool...
