I have used 3.5kg springs before and 5kg springs, 3.5 is incredibly, there is no way you would want 4kg springs. Even 5kg is soft. 8/6 is pretty standard, lot people seem to be running it daily without too much worry. I haven't run these rates before so can't comment.

BC's in 8/6, set the dampening to the softest setting and you will be fine.

Thanks guys.

I'm still a bit hesitant about the standard BC spring rates... I believe the King Springs I'm currently running are approximate 3.7/3.1 so going to 8/6 is twice as stiff, which sounds like a lot.

I will be upgrading the swaybars at the same time – F:28mm / R:25mm compared to stock 22mm/18.5mm – so a fair bit thicker. These should control body roll pretty well so I should be able to go a bit softer on the springs, right?

I'm still thinking 6/4, or perhaps 7/5 as a compromise...?

Edit: Also, since it's a sedan, maybe the weight distribution is a bit better (more weight in rear = less nose heavy) – perhaps even 6/5 or 7/6 would work?

Ended up going with BC's F:6 and R:5 at it feels great.

With regards to my original question, KYBs are supposed to work fine with King Springs even if they're not a 'short shock' per se. Around $800 or so for a full set, so not that far off from low end coilovers pricewise.

    • Some troubleshooting, connect up a timing light/gun with a proper ignition lead on coil 1. Hold the revs at 4~4500rpm and see if your timing is all over the shop, scattering off its tits. If so, there's a high chance your CAS is fked. But I read you have a Link ECU ready to go in, why not just skip all this and put that in - will make troubleshooting so much easier.  
    • Misfires when the car is fully warm are generally attributed to the coils (and/or the igniter, on cars with a separate igniter). They can stop working properly when they get hot for a number of reasons. Either electric/electronic, or from thermal expansion opening up gaps and allowing HV leakage. Seeing as you have replaced the coils, that could/should rule them out. But I wouldn't always assume so. Were the coils genuine? Or is there a chance you have bought some counterfeit Chinesium shit? Then we're back onto loom connections. They can fail when warm/hot for the same reasons. Inspections, cleaning of contact surfaces, ensuring that terminals are fully inserted, etc etc, are all justified. The same (heat effects) holds true for the other electrics and their connectors. AFM & CAS, primarily. If you try that Chinesium AFM, drive it around on low load until it is properly hot, but do'nt give it more load than you have to, except when you need to see if it will still miss. I'm dead serious about the untrustworthiness of the calibration of those copy AFMs. Injectors are unlikely to get hot unless the fuel is coming back around hot. You could try squirting them with compressed air or freeze spray to cool them back down to see if they are maybe the cause.
    • Alright, all the plugs looks good. Noticed that it starts to get bad when the car is up to temp, that's when things starts to misfire hard. next to do is Injector cleaning and such. Got in touch with a shop to do work on the injectors next Monday also help on diagnosis.

    • Hence why I've only modified my car into a pure daily. Everything has to remain reliable & roadworthy, while providing value and grin factor. It also must not be handcrafted to the extent that the car will be immovable if something breaks because you cannot get or make a replacement to at least limp around with.
