Springs and Dampers
===============
Proflex inverted coil over suspension with separate damping oil canisters running 10 bar nitrogen on gas bladder, compression and rebound adjustable, along with adjustable platform springs, these are also fully adjustable if striped for high and low speed damping too.
Bump stops 88mm neoprene down to 45mm depending on driver.
Eibach springs
The coilovers use a main and tender spring. Not to be confused with using a main and helper spring as seen on other cheaper coilovers. A helper spring effectively has zero rate and keeps your main spring in place under extension.
Use of a tender spring gives you a dual rate to manage.
Tender Spring
Front: 6kg/mm, 100mm length
Rear: 5kg/mm, 70mm length
Main spring
Front: 10kg/mm, 200mm length
Rear: 6kg/mm, 250mm length
Comment:
Long story short, if these are converted into CPM (Cycles Per Minute) and then given as a ratio front to back you get the relative stiffness of the springs in relation to the car. The following % are the front CPM rate compared to the rear. In the first example, the front Tender Spring CPM is 82% of the rear meaning in simple terms it's softer.
NME Tender Spring 82%
NME Main Spring 97%
OEM Standard Spring 92%
So the tender springs are not only improving the ride (High speed bump) but also aiding with turn in as an 82% ratio will help to throw weight over the front tyres. Once the tender springs are compressed and the main springs come into play, the car will have a more neutral spring bias.
The transition needs some further maths though I expect the free lengths are quite deliberate and the transition is smooth.
End result is a compliant ride that resists roll in corners, very clever
