Thanks for the updates. GRP is simple in theory, but the administration is a whole different story! Looking forward to more pictures.

I don't think Murph was in the wrong this afternoon, but (personal feelings aside) it's probably going to be a political call.

There there is a lot of great suff sold by NF, but as Russ implies, you don't always want to start with someone's uprights and try and reverse-engineer a suspension geometry to suit, particularly if your tyre rolling diameter and/or idealised roll center (static and dynamic) doesn't match the car (P4) the upright was designed around.

Great if you are building an NF car or something with the same rolling diameter tyres, track and wheelbase (to an extent), and are happy with where they put the roll centre. But it is often actually easier to work out exactly what you want in terms camber acquisition and roll centre control, and then calculate the appropriate inboard and outboard pick-up points. Then you can fabricate (or otherwise!) an upright that suits you perfectly.

Russs, sorry if I've hijacked your thread.
What size rose joints are you using? I'm going with heavy 16mm for my lower control arms and 13mm for the UCAs, because I would prefer the wishbones to bend than than risk a rose joint shank to break and lead to something detaching, but I am open to suggestions.

Regards to all
