Also I find alot of times a soft servo saver kills turn in and steering response (ie Tamiya). Go to the Xray servo saver with all springs installed for real steering response.

If all else fails use the new option shimizu soft front insert. Definitely more overall steering but on some tracks too much so mark the wheels 'soft insert'
