So, no, suspension upgrades aren't needed for running this Ventus 3 Pkg.
We do recommend to upgrade the suspension when running the front splitter. The stock dampers are a little weak to control the pitch under braking. This does of course depend on the ride height of the car.

The AR-1's have had 3 track days on them with roughly 11 sessions. Not sure on the temps, I start them at 25-26psi cold, and around 33psi hot. Didn't have a chance to dial in alignment for them yet as I used to run cup2's. (-1.9 f -1.5 r)

This is the wear


Passenger front

Passenger rear

Driver front

Driver rear

It is going to be my next modification!
