Wheels

HI,

We are looking for some inexpensive wheels for our car preferably 13" with 4.5 inch offset, or something close to that. Anyone know where to get some of these that are inexpensive?

Thanks!

Try Kaizer?

[Paul Gibson]

Yeah, we know Kaizer can do them, but our guys in charge of wheels said they would be $1800 for 2 sets. That might be a bit out of our range, but not sure yet. I'd just like to explore the other possibilities before so we dont have any surprises. 13 inch rims are hard to come by...lol.

[Ché]

just you (or anyone else) doesn't get confused it's Keizer (http://www.keizerwheels.com/)

not

[SnailRacer]

$1800??? Wow, looks like the 'cheap' keizers have gotten a little more expensive. But I'd wager there's alot of used sets floating around...

[Schulberg J]

Try Real Racing Wheels. A set is between $400 - 500 shipped. That price is fro 10" wheels, 13" may be more.

We purchased wheel shells, and then made our own centers, this offered us the best balance between price, and weight. And since we designed the centers we knew exactly what we were getting.

We got the shells from Keizer, and water just cut/machined the centers form 1" thick stock MAG. I don't think that I would ever buy another manufactures machined centers again. We were able to do our center for far less money then if we had tried to get them done by Kodiac or Kiezier. The wheel shells will even come with the hard ware and valve stem.

How much do the Keizer wheel shells cost?

Also, what's the weight difference between Alum and Mag wheels?

[Jersey Tom]

Difference between aluminum and mag wheel centers? Weight, strength, fatigue life, fracture toughness, machinability..

[Wright D]

The machine ability of magnesium is excellent. The problems you face are not in fabricating the center, but rather in making it stiff. The young's modulus and ultimate strength of MAG is quite low when compared to other engineering metals. It is like engineering with silly-putty. You are going to want to spend plenty of time analyzing your designs so that they are stiff and light. It is useless to have suspension with excellent camber control and tow control, just to have wheel centers flexing all over the place.

We spent ~ 55$ per shell, and got the material for the centers donated.

The nice thing about he three piece wheel is it's versatility. You can change wheel width and offset, and keep the same centers. This means that you can have more design options for less $$$. Since the wheels are modular, they can easily be repaired. If you strike an object that damages a shell you can change that shell and not junk the whole wheel. Also the aluminum shells can be bent back into proper shape(assuming the amount that they are out of shape is small, say less then 3/8 on an inch) The ability of the spun wheels to deform rather then crack also means that they can absorb a lot of energy in the event of an accident. Of curse caring around all the nut and bolts on your 3 piece wheels is a trade off.

All magnesium wheels are almost always cast and then machined.
The cast magnesium wheels will crack after a much smaller amount of deformation. This means it is far less like that you will be able to repair a damaged rim. The magnesium wheels also absorb less energy in a accident then aluminum due to there more brittle nature.

We carry a Mag centered wheel that is our most costly peice. We also cary two styles of alum Wheels that are a bit more cost effective. Depends if you need 4 or 8 wheels. Ave wieght is 6.5-7pounds. Make sure you check! No use even spending $400 for a set if they wieght 10pounds each. 2/2/06pricing 8-13x6 3pc alum wheel=$1400 8-13x6 3pc alum=$1900 8 13x6 comoplete Wheel Sheels=$1000. the two outer shells will weight aprox 4.5 pounds ready for centers. Our wheel shell packages include Hardwar for your centers and Sealent. We can seal at the factory or send it along. Current delivery 3-6 days. Also a 10x6 wheel shell will run aprox $84each for 8. Any q's please feal free to call. 712-737-3053 kaw@mtcnet.net

Mag does cut like butter, but be careful of running it hot. There's two schools of thought..

Flood it, hope it stays cool enough so the chips don't ignite. If they do, the addition of the water from the coolant in the reaction leads to a big cloud of Hydrogen very quickly. Bad news.

Or run it dry/air blast so that isn't a problem.

Remember that tools these days are designed to put the majority of the heat generated by cutting into the chips, rather than the tool or part, and this increases with spindle speed. Your tool and workpiece might be warm/hot to the touch, but the chips coming off can be a couple hundred degrees hotter. Its the chips that ignite, rather than the block youre cutting.

Lot of job shops that run mag have buckets of sand near their machine they can dump on there if it goes up.

At my coop they made lots of mag housing. They would just put a block of magnesium on the jig and walk away. The jig was on on motorized track and you get in line for one of the four CNC machines to do the job. They made about 20 different designs on this line all in random orders. When they came out of the CNC machine they would then be automacitclly routed to a huge automated CMM machine. Then it would finally come in contact with man again.

Of course they had a halon fire suppression system that gave you 30 seconds to leave the floor before there was no more oxygen in the room.

[kozak]

halon is awesome.

I worked for a mag die caster and we had D130 (I think, can't quite remember) flux all over the place. It's nasty stuff when exposed to air.
