Weight is a huge factor, because if I recall, that vector is multiplied against the RPM vector that is squared, when calculating tension forces in
the piston pin area during TDC reciprocation.
Further because of this increased speed piston experiences greater momentum which is harder to control at high RPM and requires stronger crank, connecting rods,
piston pins, etc...

Not exact matches
To be safe, the general consensus appears to advocate SilGlyde type grease for the
piston area, also the sliding
pins of the caliper; many who tried other lubes regret it eventually as the moly greases slowly swell the rubber of the boots and bushings.
On anything rubber or that comes in contact with rubber, such as the guide
pins, their boots and the
piston, I use dielectric tune - up grease (silicone).
Set # 3: 3
pistons are good, dome crowns, but 1
piston is cracked at the bottom through the opening under the
pin.
Hard knocks that happen at startup and go away quickly are a sure sign it is an early failure and oil related to a rod or main knock,
piston slap against the cylinder wall and wrist
pin knocks will persist after warm up and get worse with engine rpm.
Compression forces at BDC are far less an issue in terms of connecting rod /
pin /
piston stresses.

piston slap or wrist
pins.

pin in the
pin bore on both
pistons.
It is rare a Master Cylinder is the cause, but I have seen this a few times myself, some brake boosters have adjustable push
pins, if they are adjusted too far out they will hold the master cylinder
piston in just enough to block the return port, and it does not take much inward
piston travel to do this.
On many older designs you can hear the
piston slapping within the cylinder as it rocks back and forth on the wrist
pin.
You have to look closely at the image above but you can see that the
pistons are not sharing crank
pins.
In came a 261bhp version of the latest 2 - litre TFSI turbo, the extra power over the regular 197bhp TFSI coming from a new, bigger turbo and revised intercooler, but Audi also fitted strengthened conrods, gudgeon
