Explanations:
The raise from 160 to 170 armor is consistent with all the other Gundams' main abilities being raised 10 points, and the evidence can be seen in the 0.4 ton increase.  The 20 point increase to speed would be reasonable due to the conversion from desert to space combat, and would also mirror the Heavyarms Kai's boost from the same conversion.  10 points to weapons would be caused from the addition of the beam machine gun to the Sandrock Kai's arsenal.
Tactical Discussion on the Gundam Sandrock Kai Sandrock Kai with beam machinegun and cross crusher
After the Sandrock was salvaged and rebuilt, it was refit like the Heavyarms for space combat.  It gained extra speed from the thrusters, and recieved several upgrades, including extra armor to make the Sandrock Kai the heaviest armored Mobile Suit in Gundam Wing.  A beam machinegun was also added to the Sandrock Kai's arsenal, adding to its weapons ability.  The Sandrock Kai is a well-rounded Gundam.

Weapon Analysis:

2x vulcan - these weapons have not changed in use from the Sandrock.

2x homing missile - one of the few long range weapons at the Sandrock Kai's disposal.
heat shotel
2x heat shotel - with the Sandrock Kai's superior strength, these heated blades can still cut through even Mobile Doll Gundanium armor.

2x shield flasher - this shield-mounted equipment has not changed.

1x cross crusher - this combined weapon has the same uses as the original Sandrock's

1x beam machinegun - this rapid-firing beam gun supplies the Sandrock Kai with some much needed medium and long range firepower.  Perhaps parallel in power to the Heavyarms' beam gatling cannon.
