You got the swaybars already, you could keep using the stock links unless you want to corner balance along with adjustable coilovers, as is my car without corner balancing is only 7 pounds off.
If you keep an eye out and grab a set of gently used pss9 that come up for sale from.time to time, or even just a set of the eibach pro springs (still made for uk market) that also come up from time to time you would be able to get a little lowering and get that extra camber, I am at -2.5 front and it is working well for me
