The phrase "roll center" refers to a point in a vehicle's suspension system where forces from the body's weight and movement are concentrated. It determines how the vehicle handles during turns and helps maintain stability while driving.
Full definition
With Mustang at standard ride height, front
roll centre height is just over 2» above ground.
Tests on Mustang showed that raising the
front roll centre resulted in a substantial increase to front roll resistance and a significant reduction in suspension compression of the outside front wheel during cornering — equals less roll.
This means that they can design their own rear suspension geometry, rather than adopt what Mercedes have done this year with their raised top wishbone which lowers the
rear roll centre for better traction.
The production car most closely aligned to the Concept M4 Coupe is the recently released 435i coupe, which is powered by BMW's classic 225kW in - line six - cylinder engine and the
lowest roll centre in the entire BMW model range.
Mustang KCA306 Product Information Whiteline diagnosed 2005 on Mustang with a basic Macpherson strut front suspension that has
poor roll centre control and excessive bump steer.
A Whiteline «ROCK» is designed to raise the front
roll centre geometry by using specially engineered ball - joints and tie rod ends while still maintaining original steering geometry.
Add paper towels, torn up cardboard boxes, cardboard egg boxes,
toilet roll centres and scrunched up paper to restore the balance.

Starting with the fully independent suspension — featuring long - travel coil - sprung struts front and rear — revised rear suspension geometry was adopted to raise the
rear roll centre.
It scores a thicker rear torsion beam, stiffer suspension bushes, different geometry on both axles,
lower roll centres and new front suspension knuckles.
We then have a theoretical point in space known as
the roll centre, which as its name implies is the point about which the car rolls and it represents the interaction of the various suspension components and the leverages they exert over each other.
Losing of the roof seems to have had zero effect on the driving dynamics too, in fact, the SLS roadster seems to display even less roll than the coupe through demanding direction changes, so I suspect
the roll centre of the chassis is lower now the roof has gone.
The overall outside edge - to - edge distance is 4 - inch (100 mm) wider at the front and 9 inches (230 mm) at the rear over a 900 Turbo of the day - mainly to decrease
the roll centre height and improve turn - in response.
This was done to lower the height of the suspension system and
the roll centre.
Compared with the standard Polo on which it's based, the GTI also has completely different front suspension knuckles, a stiffer torsion beam at the rear, rerated suspension bushings and entirely different axle geometries and
roll centres.
