We have been working on several projects with Velox and will be unveiling them over the next few weeks. First up we have a new LCA that is in development and soon undergoing testing on a couple time attack cars. :)
There are a lot of options out there when it comes to Lower Control Arms for the twins. You have simple units like the SPC arms all the way up to full CNC Aluminum ones as we'll see below.
The factory lower control arm as I am sure you all know lacks any sort of camber adjustment. This does not work very well for those of us who decide to lower the vehicle or do any sort of motorsports with the car. Working with Velox it was decided to completely redesign the LCA to reduce the most amount of unsprung weight possible, give racers a lightweight and durable solution.
To get started we got 3D models of the OEM unit. :)

So how can this be improved upon?
1.
Weight: Lighter than the OEM and other aftermarket units. This helped us determine which material to use.
2.
Packaging: We wanted our LCA to retain OEM mounting points. This allows the LCA to be used on a stock suspension set-up , as well as coilovers, and not lower the rear of the vehicle like other units geared more towards stance. This is what ruled out the above design.
3.
Manufacturing: We decided early on that we wanted a machined component. With a cut, bent, and welded steel unit, tolerances are looser and heavily dependent on the shop doing the work. On the other hand, a modern CNC machine can hit tolerances tighter than 0.005″ without breaking a sweat.
4.
Strength: We knew we wanted a LCA that was ready to hit the track. From daily drivers, to enthusiasts, to all out time attack cars, this LCA had to be handle the punishment.
Several ideas were constructed but weight was still a tad high.

A finial design was settled upon once more weight savings was created.

Everything has been created via 3D models from OEM supplied 3D data. It doesn't get any more precise then this guys.

Stay tuned as we test tension, deflection, and overall strength. :)
