The Qa1 moves the wheels forward 1" which I do not like, it can cause clearance issues depending what wheels you run.
Id run a quality K-kember kit up front (comes with K-member, a-arms, coil over setup-minus shocks), Id get it without motor mounts since your running a front and mid plates. If your interested Im a UPR dealer and can set you up with a package deal, great price. Are you going to run aftermarket race brakes up front? If so Id go with a 1" shorter a-arm to compensate and keep the tires tucked nicely.
I run the UPR set-up, no motor mounts with a tow hook, 1" shorter adj a-arms.
I'd run Strange Adj struts up front and Strange adj shocks out back, for the low cost you can't beat them they work great.
I know a guy with a 340 stroked to 410ci (off the top of my head) in a full weight Demon that goes 10.4.
I see SRT said the same thing, guess I didnt type fast enough..lol
