I recently visited a few wheel places to get a good first hand look at some new rims, however the one shop that gave me the best customer service, said that the IKON wheels were great quality and low price - yet I've never heard of them (to be fair, I haven't heard of many of these brands before)

I was leaning towards either one of these:
IK85 Pace
IK83 Xeno

They do have some heft, but not overly bearing, but these do look pretty good. Thoughts/Opinions?

 

I'm not a fan of the Xeno, but the Pace doesn't look to bad.

Now on to my concern, both links show the rims as 5x114.3. Going off of your profile, your G5 GT uses the same 5x110 bolt pattern that my SS uses. I don't think those rims are going to work unless you have done the hub conversions.

 

They do have the 5x110 version of the rims.

My real question is: how well this brand holds up from the elements, and typical use?
