You can see the results of the JF Customs kit, as installed by someone else on the forum
here.
To me, the issue with these kits from
JF Customs is they literally seem to stitch 2 bits of leather together and don't do any thinning which means there's an unavoidable ridge at the seams. And when you fit it, it's virtually impossible to fit straight/aligned to the sharp edges of the trim.
Here's the link to a forum member who was offering replacement Piano black pieces.

We are looking at the leather dash, console, and headland panel trim bits available as a kit from J-F-Customs, vendors on Ebay. UK based company, New Malden in Surrey. Pricing seems good. Probably not a job to tackle unless you have had tons of experience with adhesives and leather. Best done by a professional trimmer. As an alternative can recommend the carbon fibre 3 parts assemblies produced by carbonized-bg.com They did the work for our E86 coupe to a top standard for a reasonable cost including courier out to the colonies (New Zealand) we are delighted.
Both of these options you can have fitted to your car for considerably less than the carbon options second hand off a M coupe. We looked at two sets from different sellers and they were badly marked, hence we travelled the road we did with C/F. Third option is to remove and get the bits painted gloss black.(Piano black) and refit. Another coupe purchase looms unfortunately it has the ali trim and thinking of the leather option for this car.
