Default BFH how much?

Just got my tires and wheels on.
18x11 Weld RTS wheels on rear.
315/30r18 Toyo R888R.
Im lowered on Strano springs.

How much hammering of the inner wheels wells do I need? I've only done the passenger and I can fit most of my hands between the inner fender and the tire. Is that enough in general? I know I can go drive and see what rubs, but wasn't sure when to stop the massaging. Haha!

Thanks!

I'm not sure I can quantify "how much" but my inner lip is not 90 degrees perfectly vertical, seems to be about 45 degrees to 60 degrees upward at most. I have a TA tho, so YMMV based on Camaro and wheel offsets and even tires (ie, BFG Rivals are way wider than some others). I get no rubs on the lip.

Do you think you have an inch clearance from the inner most point of the wheel/tire to the inner fender? Or is it closer?

I have 315 P zero on 18x11s and I had to BFH. Just checked clearance by hand 5 minutes ago and I'd guess I have 3/4" between tire and inner wheel well where I did the BFH'ing. I haven't had any rubbing issues. I do still need to roll my fender edges...it has touched the outside edge of the tire

Awesome, Thanks!! This helps greatly and gives me an idea of how much I need to do.

Yeah I also have to get my fenders rolled.

What offset are the wheels? 315 on 11's take up a lot of room and like someone said it's hard to quantify "how much". Also, less with a Watts link than a PHB, etc. A +50 will need more massaging than say a +40 wheel. But there are a lot of those prior sub-issues that play in.

The offset is +43. I also have an adjustable PHB.

Because any and all panhard bars are asymmetric, whether they are adjustable or not understand that the body will swing in an arc regardless of where the adjustment is set. Essentially that means if you make it look all nice and square you might find that it rubs the left rear on the inside and maybe even the right rear on the quarter panel. Not at all atypical to have to skew the body to the left.

My rear wheels are 18x11 +50 and I have a watts link. With your +43 you'll definitely want to roll your fender edge...unless I'm thinking of offset backwards

Nope your correct. The +43 would push the wheel outwards more than your 50. I def plan to get them rolled. Don't want to risk it.

Sam, you said with a watts link what will be less? I have a Fays2 ready to install with 315s and will need to do all this real soon.

How big of a hammer and how much force, a nice knock at the door, put a nail in the wall, or punching a hole in a wall?

I used a 3-4lbs sledge and swung semi hard. Not full blow. You'll know bc you can see how much it dents in and what's needed.

The secret for clearencing wheel wells is to drive over speed bumps at 60 mph.

A double adjustable panhard is the way to go on that issue. I have OEM C6 Z06 wheels, 19x12 with 325's out back. Had to bfh, grind a little, tubular lca's and roll my fenders but fit with no spacers. Just make sure you are test fitting with rear suspension loaded. Took multiple test fits and licks but its fairly easy. Now I can corner hard with no rubbing. And rolling the fenders simple with right tools.
