I have done it in my car, uncomplicated.

We removed the proportioning valve from the ABS (screwed on) and instead put an aerocup line through the cockpit, basically from the ABS unit to the splitter in the rear. We put a Tilton bias valve in it, works ok.



This is an early picture of my car.

I don not have very recent measurements. Start of the year it was 52% front, 48% rear, diagonaly perfectly balanced. If I recall around 620 F, 575 R.
That was before the new doors and the lexan hatch.

Hans,

looking at your car is it possible to just remove the bottom half of the dashboard?
I am looking to do it, but if you can advise will save me sometime, I don't want to have to cut anything. Basically I want to remove all the white bits of in the following photos.

I do not recall exactly, has been two years.

My dashboard is a special made carbon, weighs 350 gr.

You can definitely take out the glove box. It is not very hard to take out the complete dash see Clarks Garage
Once it is out it is easy to cut it. 10 minutes with an airsaw does the trick. If I remember correct the complete dash was 7 kg, so worthwile to remove.
