Default understear

Hi, I have the Ohlins DFV with Cusco stabilizers and tyres 225/45/17 fr and 255/40/17 Re. The Car is 99 JDM
I use the manual guide for adjusting the suspension except in front where I adjust the height 2mm more because I was hitting the fenders.
All around the ride height is 345mm and from the ground 110mm fr and 115mm back
What kind of alignment would you suggest?
Right now I have:

Fr.
Clicks 8 (25 is softest)
Caster +5.70mm
Camper -1.45
Toe 0.00

Re
Clicks 10 (25 is softest)
Camper -2.25
Toe +1.70

And the car is very much understear and you can’t drive it at any circumstances to the limit.
ANY ideas or suggestions to stop the understear and for the best alignment.

Thanks

Vass

Try more front camber, at least -2 and more if you can get it.

That's a lot of rear toe in -- why not just dial some of it out?

+1.7 is degrees or mm?

So the car is understeering = the car dosnt want to turn very well or change direction? Is it unresponsive at turn-in as well?

What are the spring rates F&R?

Does the back end ever slide out?
