5x4.5 = 5x115mm .. right?

The new Molars are running 5X115mm bolt pattern wheels. 4.5 is 114.3mm. The wheels will NOT work without being red filled or using adapters (I would weld and redrill before I would use adapters). Whoever measured your wheels did not do it correctly. Are they close....yes. Will they bolt on and tighten up.... yes. Will they stay tight.... only by flexing the studs slightly. Is that a smart thing to do.... no.
I'm not trying to start a long argument, but be safe. For you, your car, and the safety of those around you... do it right. If you can't find the wheels you like in your bolt pattern make the proper modifications so that it's safe. I have many years experience with tires and wheels.... and sub par work in such an important part of the car just isn't worth the risk.
