Note: slow steering response in RR cars is surprisingly common — especially in older cars.  While RR cars can be lively at the rear, they often feel lazy, vague, or slow to rotate on turn-in, especially at moderate speeds.

​

Causes

 

• ​Very light front end: not enough load on the front tires - reduced bite and feel

• Stiff front suspension or ARB - prevents the front from compressing and gripping quickly on turn-in

• Too much rear grip - rear won’t rotate, so the car feels like it wants to push forward

• Alignment too conservative - not enough front negative camber so slow response to steering input

• Rear-heavy inertia - rear-end mass resists rotation, especially on initial turn-in

• Throttle-on driving - loads the rear further, keeping the front light and unresponsive

​

​Fixes

​​​

• increase front aero (helps plant front wheels and helps the car turn-in and rotate faster)

• reduce rear aero (prevents rear from overpowering front at turn-in)​

• soften front springs (lets front tires compress and grip more quickly)

• rear springs - match to front or slightly stiffer (encourages car to rotate naturally)

• soften front damper compression (helps weight transfer into the front for better turn-in)

• stiffen front damper rebound (quicker recovery after turn-in)

• stiffen rear ARB (helps rear rotate and makes front feel sharper by reducing rear grip)​

• increase front negative camber (keeps the tires flat in corners during lateral load thus generating more contact and grip)
