Wheel Spacers

I was thinking of spacers, just to fill the arches better. How are you guys getting on with your car insurance though 
I believe a lot of insurance companies don't like wheel spacers, but I don't see why 
Providing you're using the correct lengthened wheel bolts, what's the difference?
Just wondering.....

Insurance companies don’t like any kind of modification they think may increase the risk, even “sporting stripes” or wheel spacers may indicate a driver that is sporting and are a higher risk. On the other side having a wife or partner as a named driver is seen as a lower risk and will quote a lower premium, mine benefits me by £100.omegabri said:I was thinking of spacers, just to fill the arches better.

Don’t ask me to justify that way of thinking, that’s the way it is.

Why? Adding spacers increase the radial force on the bolted connection. An example of this is: -
Hold the end of a pencil between two fingers and with your other hands fingers hold the pencil adjacent to the first hand, then try and move the second hand down. Then move the second hand further away from the first and again move the hand down, you will notice it is a lot easier the further your hands are apart, and here lies the theory of levers.
Moving the wheel further away from the hub, and thus increasing the length of the bolt, increases the radial load in exactly the same way. The lip on the hub and spacer is to aid concentricity, it does not give any significant support against radial loads.
Bolted connections are complex, with many factors that influence the required safety at yield point of the bolted connection, personally I don't like spacers and I would avoid them if I can, modifying a motor vehicle beyond it's design makes you responsible.

Fair point
