@TryHard: Last week their website worked just fine, but today it seemed offline. I sure hope it's just a problem they're having with the website, not with their business. I liked the CVS Driveshafts, and I quite liked the pictures I saw of their touring car...
@mattr: Could you tell me more about this?

What you mean with off axis torque (plus, what the result of this phenomenon is on handling, durability etc), what angles you can use it at all, and without off axis torque problems, what other issues you might be facing and lastly, if there are any solutions to this that you could share with us?
