XRAY - Model racing cars

hello guys.
After reading quite a lot of posts in this site and articles from other sites as well as the Xray tuning manual I picked and made a list of some tunings that can be done in order to fix some handling problems.
I dont know if they are correct since I have never tried them I just copied them from various posts but I am sure there are a lot more other tunings that can be added to solve these issues.
Please correct whatever is wrong and add whatever is missing.
I think this will help guys like be that are newbies to this hobby

Need More steering
thinner or no front sway bar
lower front roll center
Less rear toe in
lighter rear Diff
reduce caster
more rear droop
more neg. front camber
softer front springs
less negative rear camber
less downforce in the rear
softer front shocks
lighter front diff
harder rear springs
thicker rear swaybar
more downforce in the front
harder rear shocks
less caster

On-power steering
lower front roll center(higher position of front upper arm)
more front droop
more caster
more front toe in

Oversteering
shorten wheelbase
lengthen rear camber link, try diff locations.
try to "steer" into a corner, not turning the wheels to quickly
increase rear toe in
straighter rear shock mounting positions on shock tower
lower rear ride hight
increase rear camber
softer rear springs
stiffer front springs
Thinner Rear swaybar
Thicker front swaybar
less negative front camber
less positive rear camber
less downforce in the front
more downforce in the rear
softer rear shocks
stiffer front shocks
lighter rear diff


more rear traction
more rear droop
higher rear roll center (low holes on rear shocktower
softer spring
less rear camber (increase traction entering and in corners up to a point)

Swaybars
Smooth high grip conditions, thick sway bars FR and RR (say 3.0mm)
Bumpy high grip conditions, mid range sway bars FR and RR (say 2.6mm)
Low grip conditions (bumpy or smooth), light range sway bars FR and RR(2.4mm and lower).


A nice thread about engine tuning
