Actually I worry about every pound of unsprung weight. But thats just me...a former desert racer.
I weight going from 33 to 35, the trade between weight and ground clearance. I don't add a huge 1/4" truss when it's not needed. I do run quality alloy rims instead of bigger axles. It's all related!
You also have to weigh all upgrade by cost. This is a cheap way to keep runs from bending. If that's the biggest problem you have and cash is short, good solution.
What is the negative effect of all this added unsprung weight going to do for me at 2mph? I understand it increases my braking and acceleration but that sucks as it is already. I'm happy with my choice, these rims won't bend at the lip any more.
You going to KOH this year? Explain to those guys your story about unsprung weight and how all the added weight of truss's and heavy duty axles isn't needed.
Vanimal said $200 a set. Cheap used aluminum wheels. I have a set too. Cost less than new steelies
Why would I have to buy new aluminum rims?
I'm not saying the OP wasted his time at all. Way I see it is that those rings do add strength and protection. Who cares what they weigh and how much aluminum rims cost for race alloys?
