I looked at mine, replaced it because it looked bad and the new one lasted about 250 miles. Not sure if it was from a bad batch but ended up with a britpart piece.
Shortly after the car developed a vibration again, so I binned the donut and fitted the inlet flange and prop from a 200tdi. Turned out to be a UJ rather than the donut second time around :doh:
I think my biggest problem is the suspension lift. It seems the donuts dont like the amount of flexing they have to cope with if the car is lifted.
I still have the original which I only deceided to replace cause it looked iffy and I have the Britpart one I bought to get home with, Only done about 500 miles.
The shredded one got returned to the supplier and I had a refund.
By the way I'm running a 4" lift, +2" springs and +2" blocks with shock drop plates
If the Britpart one is the right price I would be interested eGay is my other choice - I would rather be sending beer tokens to someone who would otherwise just have it as a paperweight...
