Took the leap

The front suspension geometry is odd, might be the angle of the photos, but I suspect it will be troublesome given the upper and lower a-arm pivot points and the steep angle of the upper arm. Maintaining proper camber and alignment, and avoiding bump-steer as the suspension articulates is what I'd look at. Not sure how that will be achieved with that geometry. Hoping I'm wrong and just not seeing it in the photos.

I agree with Antny and can advise that the problem is the top wishbone or "A" arm mounting is way too low; ideally the upper and lower wishbones will be close to parallel and it would be advisable to add in about 6-8 degrees of anti-dive on the top arm mount (rake it backwards to load up the arm through compression travel) - again, I think an engineer is your best bet right now mate. The other thing to check (and is absolutely critical to how your car drives) is the positioning of the steering rack, as you have to test the bump steer deviation through at least 3-4inches of travel in rebound and compression to ensure minimal movement of the steering knuckles (front uprights)
The other factor is to ensure good positive castor has been applied in this chassis set up (6-7 degrees is good), as I can see that you have no adjustment for this and that again is critical to how your car will handle. Sorry to load you up Stephen but if you are not completely sure of what I am talking about seek advice now before going any further.

Gents,

Thanks for the feedback, don't think the photo's I attached are helping. I do appreciate the feedback but its clear I haven't given enough info.

Front wishbones are parallel (With coil overs installed) and mount points are racked back. The steering rack is mounted as per attached pic.

Mounting point for pedals/steering is coming along.
