Default Hard knocking when launching hard

Ok ever since I put this suspension package together something hits hard when I launch the car hard. I think it may be the tires hitting, but not sure and this is the only time I hear it hit.

I put the San Strano springs and Koni's adj shocks and also an adjustable torque arm. The car is obviously a lot lower, looks great.

Should I have the LCA relocation brackets welded on, think that may solve the problem? The car also has a Moser rear, adj panhard, Sam strano larger sway bars.

Thanks

I would double check the torque arm bolts and for the torque arm hitting the floor in the rear near where it bolts on to the rearend housing.

did you replace the factory torque arm bushing? its is a 2 piece design and prone to wearing out. I had a similar clunk on hard launches, it was due to the bushing wearing away and pretty much leaving the TQ arm unsupported and banging around loose in the bushing mount.
