BC ER coilovers or OS Giken LSD??

Which of these two would be more beneficial for autocross? I'd love to get both but it gets really expensive to get all at once. I'm on my second season auto crossing and Im fully hooked. Since Im supercharged it automatically puts me in SSM so I'm not expecting win any trophies for the time being but want to get the car ready for second set of wheels with hoosiers down the road. I'm running stock suspension with Michelin PSS 265/35R19 front and 305/30R19 Rears. Still about half the life left on tires so there here to stay for now. Along with LSD or Coilovers I will be getting SPL front camber arms, whiteline sway bars and 20mm spacers to increase front track width. The car is not DD so I'll be going with little more aggressive alignment as well. I'm leaning towards the LSD because I keep finding myself constantly modulating the throttle. I think with my power levels the LSD would help a lot to put the power down on corner exits. But I'm not 100% sure which one would make bigger impact on the car's handling performance. If any of you could chime in I'd greatly appreciate
