I have a 2000 si and am looking to get some 16" gram lights. Does anybody know what the centerbore of the si and of the gram lights is? Do the gram lights come with hubcentric rings?

 

what the hell did oyu just say

 

Hubcentric rings slide over your hub to ensure your wheels are placing the preasure and weight of the car on the hub and not just the lugs. OEM wheels are made to fit perfectly around the hub. Notice how your stock wheels have no gap between the hole in teh center and the hub? Some aftermarket wheels have larger holes in teh center, so you need rings.

Anyway, talk to the company you're getting the wheels from. They should have a chart or list of the size rings you need. Otherwise, I'd call honda...

 

Or if you have stock wheels measure those.

 

all of these people with aftermarket wheels and nobody knows?

 

The rings are usually sold by the wheel/tire place, not the wheel manufacturer.

 

When you order your wheels they come with the hub centric ring, now unless you are running different brakes (GSR ITR) then they will send the correct rings for your wheels.

Each manufacturer is different so they send the appropriate hub centric ring.

 

What happens if you attempt to mount a rim without a hub ring?

i.e. there is a gap between the outside of the hub and the inside of the center of the rim.
