Mcgard Silver Locking Wheel Nuts for the S1 Elise and 340R with OEM wheels
Key features Include:
Computer generated extra narrow groove key patterns.
The computer generated key designs allow for an infinite number of key patterns. The narrow groove resists the intrusion of lock removal tools into the pattern.
Through-hardened steel construction.
We use only restricted chemistry steel, made specifically for McGard. These special standards insure the structural integrity of each and every fully machined McGard wheel lock.
Every lock is through-hardened and tempered, reaching the depth of hardness needed for its unsurpassed level of security (unlike case hardening which is only a surface treatment).
Precision threads & bearing surfaces.
Core integrity and precision machining provide the highest strength in the industry. All McGard locks and lug nuts meet or exceed the highest OEM proof load standards, 135,000 to 160,000 PSI.
McGard’s standard for concentricity of the bearing surface to the pitch diameter is 30% more precise than OEM standards. This insures even distribution of the clamp load and uniform seating of the lock to the wheel.
Supplied as a full set of 4 Locking Wheel Nuts and 1 Removal Key.
This fits the following models:
- S1 K SERIES ELISE
- LOTUS 340R
