wheel base
The MTX3 lacked initial turn in .
Shortening the wheelbase and using 1mm offset rims solved this problem.
The front arms top and bottom had 2mm ground off the rear then a 2mm caster clip was placed in front of the top and bottom arm plus a 2mm spacer on the sway bar mounting screws.
Shorter wheel base .
Widen the track width with 1mm offset rims changed roll centre.
Both combined helped the cars lack of steering compared to the RRR.
Car was much easier to drive.
