Hi Zdan,
The tyres are brand new. Date stamp 1120.
My coilovers MCA: 6kg front and 4.5kg rear
BC Racing is 6kg front 7kg rear
Silvers are 6kg front 7kg rear.
But do note: MCA are the official sponsor for the Australia 86 series.
They certainly know a thing or two about 86s, their motion ratios and both street and race capabilities.
I spoke to the owner who informed for a sporty yet still good ride to get that specific spring rate combo. Their standard spring rate was 5kg front and 4kg rear. He mentioned for a daily and wanted to be sporty that these rates and obviously their specific valving are great.
The main reason I actually selected MCA was because I believed a) they actually know how to design and engineer a good valving system and b) they've been working on 86s since they came out and are the Australian sponsor for the racing series.
As church said, there's a bit more then just the spring rates.

I want to play with the height of the coilovers because as I mentioned and checked before the passenger side is like 5-10mm taller then the driver side. Perhaps this was to account for the weight of a driver?
Idk. I'm going to get it levelled first in all 4 corners as MCA recommended it to be 350mm from centre of wheel to guard in all 4 corners. (I also like this ride height as its very practical but looks good).
Then once that is dialed, get the alignment.
I know what you both mean by setting it from stiff to soft and no the other way around, but like at the end of the day, it still has the same amounts of click from stiff.
Also being 2 from soft (or 10 from stiff) was what MCA recommended.
I'll be playing around with this anyway as Its cheap and very easy.
I am thinking of playing with tyre pressure and lowering to 32 psi cold on all 4 after the alignment.
Its easy and simple.
Yes, all along when I've been trying to sort this out with my partner we've both being changing one thing at a time and both driving it to see how it feels.
No doubt there is a lack of grip in the front.
Having 2 drivers feel the same problem as well as comparing it to a baseline (older rwd low power car without electronics and with new tyres (mx5)).

Coilovers are brand new and I'm pretty sure its not riding on the bumpstops. Nothing sounds rough or clunky, and the wheels are very "safe" in terms of offset and size.
Also for the rake, I'll be keeping it level as per my coilover manufacturer recommendations.
Really I just got to wait for the alignment to happen now!
Very excited as I want this car dialed.
