The facility alone does not make the car faster. Buy cheap Rank 1 tires and suspension now, and save for Level 2 only when you can afford the unlock plus at least one Rank 2 part.
Performance or durable?
The durable Plus version gives up 1 performance point for 50 more durability points (9/20% vs 8/70% at Rank 1). With Light Damage, go Performance. With Full Damage and frequent contact, durable parts can save on repair bills, which reached $364 after one race in our career.
