Offset: Neutral or 15mm positive offset for narrow track width cars (see photo).
Material: 100% billet machined 7075 aluminum.
7075 aluminum is used in aerospace, missiles, defense applications and now RC drag racing wheels!
7075 aluminum has excellent memory and rebound characteristics and keeps its shape better than all other grades of aluminum which allows it to be machined in very thin ultralight sections.
Catalyst TRACK Series wheels are extremely lightweight and are designed ONLY for smooth track surfaces with no more than mild seams in the pavement.
