Just the look. Nothing else.
I like to avoid spacers altogether for a peace of mind. I thought RWs compatible without spacers but it's not.
Well, 1/4 inch spacer compared 1.25 inch spacer is a totally different thing. 1/4 is a real spacer but 1.25 is an adapter actually.
Have an opportunity to buy a set of rock Warrior wheels (4) in good condition for $1000. Only reason for change OEM wheels is to get rid of spidertrax spacers. Because those are an added point of failure IMO.
So, have to find a fifth RW wheel. Then RW set need to be machined to fit without...
