Tire Gash??? (MS3 n00b content)

[shortwave]

Set-Up:
2009 Mazdaspeed3
BC "Type BR" coilovers
SPC Rear Camber Arms
Rolled Fenders (all 4) and shaved tab in the rear


Issue:
I was driving in to work today and I hit a nice sized bump/drop on the highway. The rear rubbed real bad and then a "flapping" noise began...as if something was stuck to the tire. The flapping was consistent with the revolutions of the tire.

Made it in to work and it turns out that the driver's side rear tire got caught on a sharp edge where the rear fenders were rolled and dug a gash into the tire. The passenger rear has signs of rubbing but no gash.

I need help from MS3 owners (or anyone) on how to raise the rear. I am a complete n00b when it comes to coilovers so I have no idea how to use the spanner wrenches (I have them with me). I am going to attempt to do this before I leave for work. When I search online I get many other vehicles with BC's but the rear set-up is unique to MS3's.

What should I do?
-Raise the rear (entire car) and how?
-How Much should I raise it (How many clicks)?
-Fender Pull (Phonebook Method)?
-Set the damping to a more stiffer setting?
-Do Both?

I love the height but I'm pretty scared driving it this low in fear of a blowout. It just sounds real gnarly in the rear right now. Here are some pics for reference (sorry for the crappy iPhone pics):



Please help me out guys!! Thanks!

this has happened to me many times, in the rear and in the front. Never got a blowout from it, knock on wood. I set mine to a stiffer setting and just watch out for every dip/bump/pothole in the road and Im usually alright...

the bc's collar and perch is on top right? i havent ordered mine yet but i would think that turning the collars down away from the car towards the ground would raise the rear.

Thanks guys. I will try this soon.

Thanks for the encouragement. I fear the blowout. I will also set the suspension stiffer as well. But for now I will raise. You guys think pulling the rear would help? I also thinking totally flattening the rear fender lip is necessary. Right now, it feels like a "V".

Yeah man get those fenders as flat as possible, really will help with it digging in. A pull would do you good too, nothin tooo crazy. And yeah damping should be on the stiff side.

I'm going back to the shop to get it taken care of. Best part is that they are doing it for free since I showed them the pics. I will have them roll it as flat as possible. They will also pull the fender. I set the rears to full stiff and it has been a little better. But I hope this final visit will be the last one...that is until my exhaust gets in. Lol!
