Are wheel spacers any good?
will they break?
how do they work?
where can you get them?
want to make 300ex stance wider so is it cheapest and best way?

 

If you want to go just a little wider, 3" in rear and 2" up front, try ITP rims (wider than stock and a greater offset) and some Holeshot tires.

If you want a full 4" (might be to wide for trail riding??), see www.sand-sport.com These are nice aluminum units. I had a set of Durablues once on the Blaster, and hated them!

 

will tires with a greater offset be more ****. to bend?
Will the tires put more stress on anything?

 

rippin-You have 300EX posts all over the place!! Never have had any problems with rims/tires causing stress.

In another post you asked about the stability of the 300. This is a place where the 300 NEEDS HELP! The rounded baloony stock tires make the bike tippy. Putting on some new rims and (square/wider) tires will make the bike wider and get rid of the round tires. Both will help stability!!!

 

will the offset rims and diff. tires be enough stab. when i get more power?
