What’s the best repair solution ?

Kossyk repair kit is pretty good, however I would say it depends where it is and how far its progressed.

Wings, inspect regularly, once it starts drill a small hole at the base to stop it progressing, then use the repair kit. Then strengthen all 4 mounting holes as a precaution and renew the rubber grommets.

The crack is on the sill panel inline with the rear of the door, about 3" long now.

Gazza, if you do decide against a repair is this any help?

https://www.ebay.co.uk/itm/BMW-Z1-NEARS ... Sw4GVYIPPJ

Doubt this is available from BMW

Not sure if this eBay item is still available? (been listed a while now) unfortunately it's green not red.

A right hand side is also available on ebay:

Or you can do what I did and go for carbon fibre from: edeldesign-tuning.de
I haven't received the sill yet tho', so I don't know:
a. how well it fits
b. what it looks like painted (will it show differently from plastic?)
Will keep you posted

It will be interesting to know, because carbon fibre is stiffer than plastic. I don't know if the sill twists when it is on the car. If it does, you could have issues. Nice solution if it works. A fully carbon-fibre Z1 would be a thing of beauty.

I had the same problem, MOT guy jacked car up resting on sill, had mine repaired, they did a very good job. Grind down both sides, rebuilt with layers of flexible material, then painted back and front.

Suggest removing sill and store safely, any further movement and crack will extend.

Plastic welding, I saw Z1 repaired front wings by this method, it is the best solution.

It seems that edeldesign tuning agreed, because they've gone and built one. I'd attach a photo, but don't know how to do it.
Unfortunately all this glamour seems to have distracted them from sending my new lower sill, so no update on that yet.
Will let you know once its here and/or on the car
