Hi guys,

I just purchased a BF II XR6t which came with 20" Simmons and 275/30ZR20 tyres on the rear (245 front).

The inside of the rear wheel and tyre seem very close to the chassis/suspension, to the point i can barely fit a finger between it.

I'm thinking i need to roll the guards and apply some offset but not sure what the best amount of offset would be for this car and wheel/tyre set up?

I was thinking of leaving the front as is, or would it be wise to offset the front also?

Lastly - when people say "+22 offset", is this referring to millimetres?

Thanks in advance.
