I got this response from a message I sent to Bilstein USA regarding the availability of the front B6s:

The product is simply on back order and should be available through your dealer by June –July 2019. Please continue to communicate with your dealer regarding their ETA on these items it may be sooner than ours.

At least I know the production of them hasn't been terminated. I guess I'll just continue to wait since I've had the rear shocks sitting in my garage for six months.

Do the B6 or B8 have the attachement points for the brake lines or do they have to be zip tied

Contacted Ross Sports in England, they had 5 B6's available, ordered 2.

Price was comparable to buying in CONUS, I was told expected shipping time is 1 week.

Thanks for the info. I cancelled my Summit order, ordered the front B6's through Ross Sport, and they were delivered in two days. Yeah...UK to US in TWO DAYS!
