Having the coilover angled rearwards like that is not terrible. It has two effects. 1) It reduces the effective rate of the shock and spring. You will just need a stiffer shock setting and higher spring rate than compared to a vertically mounted coilover. 2) It is going to add a little bit of friction to the motion of the shock.
A couple comments. You may not have enough bump travel in the rear suspension. It looks like there is about 2" of travel available before the shock housing hits the underneath of the upper spring perch. Put a small thin line of white lithium grease on the shock shaft. Launch the car. Stop. Jack it up and see how far up the shock traveled.
I think the rear spring rate is too low. To make a drag car launch well, you need high rear suspension roll stiffness and low front suspension roll stiffness. Ways to increase the roll stiffness of the rear suspension are to install a much stiffer rear swaybar and/or increase the spring rate. Alternately, you can reduce the roll stiffness of the front suspension. Which you choose to do is a function of how much body roll the car has on launch. If the car has too much roll, make the rear stiffer. If the roll is ok, you can make the front softer.
