GruppeM sold to Yorkie
Backboxes sold to John
Recently removed from my own car , the Gruppe induction kit was bought new in April this year & has covered around 1500miles , comes in all original box / packaging with instructions
The backboxes were made bespoke for the ZM in May so again have covered similar miles & are ready to bolt on once original boxes are removed , no additional works should be required . They are not overly noisy as i wasn't after raucous :wink: but they do offer a much deeper tone from stock boxes . Link here to a vid clip https://www.instagram.com/p/Bmpxasglm16/
Together the boxes & Gruppe work well to enhance the aural & visual pleasure of owning a Z4M
Would prefer to sell as thread title but will consider splitting if someone already has induction kit & is looking for backboxes .
I'm in Lancashire for collection or courier will be around £20
