Red were would one get these uprated bushes for the front of the wishbone. 
....I should have anticipated that question! The VWR guys are away racing until 5th November now, so that's the earliest I can speak with them again to find out. I know that they offer a whole set of PTFE bushes but only as part of a customer's project (if that makes sense) - Meaning that, as far as I know, you can't order a small part from them like you can from Awesome etc. They aren't a typical retail supplier.
Awesome may know where to source this aftermarket part. I'm not trying to sound elitist when I say that VWR seem to have quite a few parts made exclusively for them and primarily for their race cars.
But I'll do my best to find out for you.
