Ouch
I definitely feel your pain bud. Got rear ended by a guy going around 30-40 and shock is an understatement especially for being in accident for the first time. From what I understand, when more than one airbag is deployed the car is deemed a total loss by the insurance. I'm guessing they'll give you a rental until they give you a paycheck for it or buy you a replacement. I would definitely ask/mention it to them that the coilovers are aftermarket and may let you put the stock ones back on as aftermarket parts are not included in the insurance coverage unless you specify it when purchasing insurance. Best of luck to you bro!
