I would recommend doing this with a dummy account, as it's faster than boosting. your not relying on others, and one of you won't have to hit +20 to recoup the deficit. just make sure the dummy account has Dirt registered on their tag (boot the game or quit an event) so you can send challenges to it)
Most of us have a spare silver account lying around on our console, and this can be used.
Make sure you are on each others friends list, connected to XBL.
On your main profile, load showdown tour, all star and pick the San Fran Hard Target event. pick the Robson Avenger car (the weakest).
Now start the event. The aim is to die as fast as possible. If you just idle, you die in around 30-40 seconds. On the menu, hit send challenge and send to your dummy account.
Once it says challenge sent, instead of pressing continue, Hit restart and repeat ten times.
Then, switch to your guest profile, load challenges, and you will see the ten challenges you have just been sent. load each one up, and quit straight away, losing the challenge and giving your main account +1. Repeat this ten times.
Load up your main profile, and the achievement should pop upon registering the +10 difference.
