Rear Wheels - Wheel Spacers - 4X100 - 54.1CB - 5mm

[Kalispel]

I was wanting to pick up these 5mm wheel spacers for my REAR wheels only, to push out the OEM alloys on the SE to better match the standard look in the front, since the rear wheels seem to sit further into the wheel wells by factory default.

Any issues to be aware of? Should I buy 5mm longer lug bolts to replace the stock lug bolts, or are the stock bolts still safely long enough? If so, what size would that be for the new, longer bolts (I don't know what size the stock lug bolts are)? Would there still be enough hub lip for the wheel to sit on safely with the 5mm spacer on there?

Thanks in advance for any advice.
