XRAY - Model racing cars

i'v been wondering quite some time now what the difference is between changing the upper link in lenght or height versus lowering or heightening(is this word correct?) the arms?

Take a look at the 'Camber Rise' section on page 15 and the 'Roll Center - Adjusting Using Upper Camber Link Position' section on page 27 of the . Once you've had a look, post any questions you may have and we'll be happy to help.

x-rayted,
If you are looking at just the roll center aspect, then shifting the lower arms a certain height have a greater roll center change compared to the upper camber link with the same height changes.

Moving the lower arm = bigger roll center changes
Moving the upper camber link = smaller roll center changes

Cheers!
