This new bootlid which resembles the one one the M3 CSL features the "latest pre preg autoclave construction
with high gloss automotive lacquer" and is one of the lightest bootlids available on the market right now.
The tuner says the BMW M3 Convertible carbon bootlid is in the final stages, and it will become available at all Vorsteiner dealers soon.
No word yet on how much this upgrade will cost.
