Wilwood's innovative Wide 5 Starlite "bubble" hub is lightweight, strong, and affordable, which is why it is the standard used in many forms of motorsports and much imitated by our competitors.

For maximum durability, nuts and bolts should never be over-torqued. Use a two-step process, snugging in an alternating or crisscross pattern, then tightening to spec to spread force evenly over the hub. Over-tightening, or fully tightening one bolt before the the rest are snug, can cause parts to not seat properly, and cause mounting plates to warp or stress which can cause metal fatigue.
