^ your car is on fully adjustable coil overs. just take it to a good race shop and they can lower it to the pavement. do keep in mind your suspension geometry may be negative affected if lowered too much.

On standard coilovers you should not go lower than -10, otherwise the spring does risk to move when lifting the car or on a bump.
Changing dampers for something with pre-load springs, you can easily go as low as -20.
At -25 you put too much weight on the front (as you cannot lower the rear enough to keep the balance), so I would not do it.
At -20, anyway, a careful alignment should be done. Firstly, because of increased bump steer, which you can compensate someway going to neutral toe; this is anyway something you should like driving with: as anything related to alignment, it is rather subjective and related to your driving style. Secondly, you should increase negative camber a bit more than you are used to; you have to check this properly with tyre temperatures; by the way, to increase front camber more than -2.5*, you need to rotate the cookies.
Hope this helps,
Cheers.

Most likely, you have messed up the alignment, because dropping the ride height changes camber and toe.

What kind of front to rear rake do you have?
The only thing I can tell you is that the front is 553kg, the rear is 913kg, for a 38%front / 62%rear weight ratio
Silly enough, I didn't weight the car with the factory standard setup to note the std weight ratio, but I think I'm not too far from correct

no no no, he's talking about chassis height ratio f/r Incredibly important.
If he lowers it below 90mm it will be undrivable without more suspension changes. IMHO
