To be fair to noltec and while I can't comment on those particular strut tops, I have the
solid ones and they are awesome.
Have provided good service and still going strong. Much better than my recent purchase of eccentric tops from burtons, that dont fit properly.
There is a bit of this type of material failing of late, I've seen leaf bushed, steering joiner whats'its, and now strut tops.
Beware of nolathane (not the registered trade name, the type of material, whats it called?)
Thats the message for me.......
