1.)<br> No additional modifications would be needed<br> <br> 2.)<br> all needed hardware is included at no charge<br> <br> 3.)<br> In a specialized process perfected by Alumax, uniquely structured alloy billets are heated to a<br> semi solid state (the consistency of soft butter) and molded in a specifically engineered forging press. Through an exclusive contract with Alumax, SSR has further developed this technology and is the only manufacturer in the world today producing Semi-Solid Forged alloy wheels. This ultra high tech forging technology creates a very strong and light weight wheel ideal for street or track.<br> <br> Thanks, luke<br> 800-428-8355 ext. 362
