I also replaced my bilstein b16 lotus cup suspension at the back and bilstein b6 at the front for nitron suspension and I have a problem with heights at the front and rear. the floor is at the back at a height of 11.5cm and at the front at 10.5cm and with quite a large spring pre load. the fact that I have 215 / 40r17 tires (60cm diameter) instead of 62.5cm but I did not think that the car sits so hard.

Do you know that the first Nitrons sold for the VX were too short...

Very high camber figures.
Never seen anyone going so high...
Or may be I didn't find the right figures.
How much camber exactly ???

-3°30' rear And -3°40' front. 10,5cm high front and 11,5cm rear. I'm testing this geo.
I am very pleased with that. times have improved and the outer parts of the tires are not cutting.understeer has also disappeared.

No. I have the shock absorbers positioned equally in the middle of the stroke under the weight of myself and the car

Oh yes... you have the short Nitrons.
Then check that your rear wishbones are not touching the sub frame at full compression.

Ascending boost? Is that a boost control issue or on purpose? Explains the nice flat torque curve.
I want that curve!

I didn't want to exceed 400Nm and I want high power at the same time.the power is a bit higher because on the dynamometer I had damaged two ignition coils
