Watch-out on the rears! While I like the Street Lites, they are a STUPID design! Shyt, even the 100 year old Weld Drag Lites had something good going for them. The Street Lites do not have the same inside diameter from the axle mounting flange to the outside of the wheel. For whatever reason they step-down as you go inwards (from the center of the car to the axle flange). So, if you try to use a larger backspace to tuck the wheel under the car instead of narrowing the axle, it ain't gonna happen! They are the only company I have seen that does this. I have several sets, never had any issues with them, just wish the ID was the same throughout. Bet they did it for strength, I see no other reason to leave the extra material there.
