Hey guys, noticed you were all looking for cheap parts. I did the same thing about 7 years ago when I needed to fund my hobby on a budget. What I found was that there wasn't a lot of cheap parts out there, even second hand.
I started finding new ways to get hold of cheap parts and ended up starting my business selling the cheapest parts in Australia. Now I run a wide range of parts which are cheap and high quality.
You can buy kitted parts from my store which provides for people doing DIY karts. If you've got a chassis then I can supply everything to fit for a fraction of the price of go kart stores. The general idea is to get people out there having fun that otherwise couldn't afford it.
In relation to wheels, I can't do tallies but we do have the cheapest 5" rims around, and they are nice looking wheels too.

If anyone has any Q's fire away I'd only be too happy to see if I can help anyone out.
Cheers,
