VERY strong lug bolts, very long lug bolts, you will probably need an open ended nut. The best aftermarket solution for Nissan 350z and Infiniti G35. Mounting from the front is very easy, mounting from the back requires a little "trick" (remove the emergency drum brake, the strut into which the cable is inserted allows the bolt to be inserted). I wish they were cheaper but they are worth the price! Stay away from OEM, Nismo, bolt seals, etc.
