I am afraid nobody sells these in Doha.

Alternative to this you can get the OME from ARB Emirated, Abudhabi.

They can delivery to Doha a cost inclusive of the shipping.

For more details check with www.arbemirates.com & ask for MR. Majid.

As for Iron Man suspension system you can get it from Dubai or Saudi. Can get the contacts from this site :

Hope this helps
