I was just wondering why one team does have lost some wheels and others
doesn't.
There are a lot of very fast drivers around. They had no problem 'till now.
One team lost several wheels last year.
The drivers of that team are known to drive hard over curbs with cars
jumping high that a cat can walk under it through.

about 8 of us now using them with no failures to report. I can supply
contact information and even the "job number" so you can have a set made up.
There are some bearings and seals you'll need to source and I have numbers
for them as well as some machine work on the rear trunions to bore them out.
You should be able to find someone locally that can do it or I can run them
through my shop. It's a real slick setup and uses cheap corvair yokes and
corvette u-joints. I use aircraft alloy hardware but likely grade 8 would be
just fine.
