Dannymik Posted August 7, 2005 Report Share Posted August 7, 2005 5 X 115mm thats what is stock and preferred. FYI, you can get away with 5 x 114.3(4.5) with hubcentric rings Quote Link to comment Share on other sites More sharing options...
Justin Posted August 8, 2005 Report Share Posted August 8, 2005 You can "get away with" just 5X4.5 as well, the rings are nice but I've honestly never met anyone that actually uses them. Quote Link to comment Share on other sites More sharing options...
GnatGoSplat Posted August 8, 2005 Report Share Posted August 8, 2005 5x4.5 = 5x114.3mm My wheels came with plastic rings and they don't work worth a crap. Quote Link to comment Share on other sites More sharing options...
Dannymik Posted August 8, 2005 Report Share Posted August 8, 2005 5x4.5 = 5x114.3mm My wheels came with plastic rings and they don't work worth a crap. they sell the hubcentric rings for the Eagle wheels over on the grand prix store off of clubgp...$20 for the set since there specifically for that brand of wheels. I took a chance and saved the $$$. Quote Link to comment Share on other sites More sharing options...
GnatGoSplat Posted August 8, 2005 Report Share Posted August 8, 2005 Well, the GPStore hubcentric rings are just plastic so all they're good for is centering the wheel. You can center them just fine by torquing in the proper pattern using progressive torquing. I torque them all 30-60-90-100. The plastic rings are useless for removing the load weight off the lugs, they'd have to be aluminum or steel to work for that. Quote Link to comment Share on other sites More sharing options...

I had a bit of wobble/vibration after the garage mounted my 185's, but I fixed that once I got home. I used my 4 way and went every other lug which help center the wheel...all is ok now.
