I want to push the wheels out about 4cm, any suggestions on what kind of wheel spacers to get? 5 bolt 114.3, what other information do I need to determine what kind of wheel spacers to get, sorry I'm new to this. Thanks alot.

 

Check the back of your wheels to check if they are recessed enough to accept bolt on spacers. If not, then you will need to get the traditional spacers that require you to replace your existing studs with extended studs (usually included with name brand spacers).

Make sure they are hub centric.

 

you will need to roll your fenders first, then figure out what size you will need

 

if you want to move it our 4cm than thats 40mm... a little too much for a spacer IMO.

 

He doesnt need a fender roll, hes not even dropped. Im guessing he wants it to sit flush.
4cm = 40mm, You need a wider wheel.

 

Fender roll is recommended with spacers. I would do it OP unless you want the possibility of going over a pothole and crushing your fender or cutting your tire.
