as i look through the forum i notice people flipping around there front tires so it becomes alot wider in the front.
1.what are its benefits
2. is it bad for the tires or anything else on the machine

 

I have never had any experience with doing that, but i think it may put more excessive force on the a-arms causing them to have more stress and possible bend, might as well buy +2 asr a-arms.

 

doing that makes it act like wheel spacers and it puts stress on ball joints and changes the way the steering and suspension work while riding

 

We did that last season on my z400 to make the front end 48 inches wide (50 inches is AMA max). In order to do it you will either need to run at least 1 inch spacers on the front otherwise you'll knock off the air valves on the calipers, OR you will need to relocate the airvalves entirely(to the inside of the rim, but you'll have to plug the orig hole - that's a pain in the ****).

By inverting the rims you are putting extra stress on the rims since they arn't made to run that way so I wouldn't suggest doing any sort of jumping with the rims inverted...

I'd suggest either buying new rims with the offset you want or buying a set of +2 or +3 aarms if you want to run the stock rims (stock rims bend too) if you plan on jumping the quad. All wheel spacers come with a warning against jumping the quad with the spacers mounted.

Having the front end wider does make a hugh difference in riding. I didn't have to make any adjustments to steering when I ran wheel spacers with the front tires flipped (inverted). I'm not sure how much more stress you'd be putting on the upper shock mounts. I only mention this because Z frames are well known for having weak upper shock mounts.

Look at my picts and you'll see how wide we got my Z last race season with 1inch spacers on each side and the front wheels flipped. Note, we also had a lowering kit on at the time of the photo so that makes the quad about 2 inches wider(total) also. This year we're running +2 LSR a-arms so now we're right 48inches w/the spacers but the tires are not flipped anymore. You can get cheap spacers on ebay for around $50 for the front.
