Time for a mini project! A while back during the MOT test I was slightly concerned with how much the wheels moved about when the tester spread the front axle on the pads. Having seen a few designs of A arms at Spa and online on the boxergasse forum I've decided to give it a go myself! I wanted to do it as a completely bolt on swap. Part of this change is to de-couple the stock anti-roll bar from the geometry so this will be spaced down underneath the A arm. I've seen people put it above but my radiator is in the way and I have plenty of ground clearance.
The inner spherical joint will be M10 and the forward tension link section will be M14, I will also be using sealed boots to keep them weather tight. At the spindle I'm using the original design ball joint. Some people re-position the lower axis as they run very low.
Before I took the stock suspension off, I put the car on stands and with the steering dead ahead and a vertical level marked up the position to the floor. This is obviously just to get the geometry about right, I can fine tune it afterwards.
The key part to the swap is creating a forward bracket, this aluminium block spaces the anti-roll bar downwards with the stock saddle clamp and gives plenty of meat to mount the forward joint.
The block fitted, not how it is fitted to the chassis form. My mate, Seb, machined up some tube end fittings for it.
The first lateral link tacked together
and fitted to the car, now to align the hub and measure up for the tension link. The last bit will be to work out how to connect the anti-roll bar.
