To be completely honest with you, I personnaly have never looked at the back end of a B4.1 I've never looked to see if they will fit. I've had a couple of people tell me they don't fit, So I guess they have changed the back end? never questioned if they where right or not, Took their word for it.
Aired on the side of caution and stated that the don't fit.
I'm not racing this weekend, but I'll check it out next weekend to see if I've been told porkies :lol:

If your going to do a centro C4.1 brace, can I suggest locking the hinge pin with a grub screw - so the wishbone hinges on the pin (the pin then won't pivot in the brace). This will stop the brace ever wearing in the same way as Rich Lowes great idea will too.

I've no plans to do a Centro brace at the moment, I've had a look at the back end of the Centro and what I'd like to do, there isn't room for. I may revisit it at some point but not at the moment.

come on noel the centro gang is calling:woot:
