The wings mentioned in my earlier post are from Honeybourne. I didn't originally mention the name because I didn't want people to think I was slating them as I'm not. For the price, they're not bad if you want to use them for motorsport or something.
I think most people on here though, like myself, are looking at tidy-to-concourse restorations for their S30s. In my opinion, I'm not sure these would be good enough. I've so far spent 10-12 hours trying to achieve a satisfactory fit with just one wing and I'm not there yet. I used to work in a job which required a lot of composite trimming too so it's something I'm reasonably well practiced in.
The other problem is that when they shipped them, they were literally just left flapping around in a large cardboard box so they arrived quite damaged. They had no protective packaging at all.
I'm going to keep going with these FRP ones and see if I can get a reasonable fit out of them. If I can't I'll either buy a tatty set of front wings to cut, or otherwise make my own CF ones. I just don't want to go down that route at this stage as it's time consuming.
