To help landings & achieve smoother tip in try this...
Grind 2 m off the back of rear arm's and move the arm towards the rear, add a 2 m spacer in front of arms.
Also move the rear hub all the way towards the rear.
On high traction the longer wheel base helps smooth the car a great deal, the higher the grip the more the longer car helps


I finally got around to posting up some pic's of the areas of the rear arms with the area that needs to have 2mm taken off "as per" WC.

The stock arms come in at 37mm wide so it makes taking 2mm of them easy..you just need a cheap pair of calipers and measure 35mm

Stock.. non-modified rear arms
