Burn out issues

I was attempting a test and tune Saturday. I was going to try Vikings recommended shock settings. Double check my bar adjustment. Viking suggested my shocks were topping out.....I have extensions for the rear may try to get some bayonet extensions for the front. I really doubt that though but it won't hurt to try. And no I haven't touched a thing yet but I have to get my 60 foot times consistent so it's happening. I did verify the rear axle was square in the car though.
