After going back and forth with Richard from Atomic Fab about a dozen times, we landed on doing an X13 shock instead of an X19. I corrected my earlier post to reflect that.
Here's why:
"Generally for handling and stock-type driving, you want a shock that is around 40% compressed at ride height leaving 60% of its travel for compression. So since your mounting holes are 17.75" (let's average) you'll want something with a median ride height a little below that. [...] So with that I would go with the x13 since you will be more concerned about not having enough compression travel vs extension. Extension travel is useful if you plan to do a lot of off-road driving and need the articulation travel, or racing where you need weight transfer. Otherwise you should never really be at the upper end of the shock fully extended unless its hanging in the air on a lift in which case the load is applied slowly so it's not a big deal." --Richard, owner of AFP
The X19 shock had a 60% length of 18.28". If I take my 17.75" shock mounting hole distance and subtract the collapsed length, I'd only have 4.15" of compression travel.
The X13 will have a 60% length of 17.1", meaning I'll actually only be ~30% compressed at ride height, giving me 4.85" of compression travel.
That's a gain of almost 3/4" of compression travel!
I also went with the Berserker upgrade on both the front coilovers and the rear shocks, which will allow me to change the valving profiles at home. I ordered them with the Pro-Touring valving (GF).
Oh and I ordered his 1" lower poly engine mounts, which should help with the transmission exit-angle!
It's just money...right?!
