theres ways to get a tire to bead....theres ways...

You shouldnt of had to grind the rim at all, that weakens the bead and tire. To make things fit with the 315's is you have to bang in the inner fender. Make sure you have your back seat in place cause if not it will distort the rods it clicks into. Its not hard to hit it, hell I used the wooden end of my sledge and it bent right in. And dont forget to recoat it with undercoating after your done. Drive it for a few miles, take off your tires, and see where its rubbing, and keep banging it till your tires stop taking the undercoating off. Aslo you might have to bend your fender up top, I had a problem with ym car doing that, without anyone or anything in the back, so I rolled it up, and its never rubbed again. also if your having rubbing problems, you need an adjustable Panhard bar to center your rear.

you put a 315 on a stock rim, not good!! that size tire needs a 11, or 12 inch rim

I think you misunderstood me. I have NO problems with rubbing. The only place that I grinded down was inside the wheel. There is lip that the tire need to get over to reach its seat. This lip has a square edge making it difficult for the tire to get over it. So all I did was round that square edge. It's not like a took half the weight off the rim from grinding. Consider this more smoothing rather than grinding. In no way have I made the bead or the tire weak, because I have touched neither.
Completely true lol. however i'm not the first person to put a 315 on a smaller size wheel, and not all 315's are actually 315's. This tire is more realistically around a 295.

Heya Mensaf! :D

What have you done so far? LCA relocation brackets are definitely a good choice when lowering, but like everyone else said, I would get the SFCs installed first. If you're really anal about suspension geometry, you're going to want adjustable LCAs, panhard bar, and torque arm, too.
