Hey,

I was curious...a had a local shop that I purchased wheels from perform the installation of the rims and tires. I just got a set of 18in Enkei RP03's and I noticed that they didn't put hub centric rings on the rims.

I didn't notice any vibration issues while driving and I've read that hub centric rings aren't necessary and could cause problems.

What's the general consensus here? Should I go out and purchase them anyway? I read differing opinions about it as well as regarding aluminum vs plastic.

Thanks.

Cheers,
Dave

 

Moved to proper forum

I've never heard that hub rings could cause problems but I sure have seen a lot of problems without them.

Are they absolutely required - no, as long as the wheels are mounted correctly and carefully. Can you trust yourself and every tire-jockey to get them mounted correctly???

 

Without properly locating the wheels on the hub, all load bearing are carried by the (tiny) lugs. That's not what they were designed for and not a good idea at all. Get the correct hub rings and you'll sleep better before track events or spirited driving.

 

I read differing opinions also.

 

If your feelings a vibration while driving at hiway speeds I would break down and put some on. I have 2 sets, plastic and aluminum, only necessary on non stock wheels. This link was on top of this page.

YOu can usually find em locally, if necessary.

 

Yes rp03 needs them

dkmuras post is spot on

 

Ok, so if the consensus is that they are recommended.

What would be the type to purchase? Plastic or aluminum? This is for street driving and not tracking.

Is there an online site that might also point me to the correct size of rings to use?

 

Price wise i'm not sure the difference. But since you're not tracking the car i would go with plastic and they're designed to withstand heat. Aluminum ones are more durable though

 

The RP03 has a 75mm hub bore and the Z has a 66.1mm hub. Contact Adam there at Z1 - I'm sure he has the proper ring that fits.

 

Nope, that is an oddball size that we don't offer unless the wheels are also purchased from us. OP can contact Enkei USA for the rings

 

I've been trying the Enkei PF01 on the Nissan Sport Project 350Z T2 racer and it has the same bore size (75 mm) as the RP03. I can confirm that Enkei carries a 75 mm to 66.1 mm hub ring for use in their wheels. It's an aluminum hub ring and costs about $8, which is a small price to pay for peace of mind.
