28x10.50x15 Et Drag clearance pics?? installed my new tires today and did a bunch of clearancing (ie cutoff wheeling). basically cut off the metal from the fender/ground effects area in front of the tire and all the excess from the rear bumper. i have about 1/2" to 5/8" clearance on front and rear. i can basically run one finger between these areas and the tire. i also centered the tire perfectly with the adj lowers.
from what i have been told they may still rub with this much room, so i was curious as to if anyone has pics of the clearancing they did to get the to fit without rubbing as i do not want to cut much more than i have already
i will post pics tomorrow of what i have done (car is stuck at the chicks house, starting raining as i was driving)
thanks

One trick is to drill a small hole in the rear bumper by the slick, and run a wire to under the car and pull the bumper back a little bit, rather than cut it. Know what I mean?
If I can put my thumb between the tire I'm all set. Never rubs.

yeah i know exactly what you mean (i sell aftermarket wheels and tires and do that alot when putting 26"s on trucks) i was thinking off pulling it back and cut it instead, which im second guessing although there is still enough for me to drill a hole and pull back
my biggest concern is in the front because i really dont see how i can take off much more (the last pic shows what i cut, basically right along the seam)

Looks like you did exactly what I did, I'd go take some pic's but my camera is on the fritz 
I cut a little more out on the bottom in front of the tire, there's a line on teh body that makes the bottom look like a triabgle, I cut that little area out. I was worried the tire would grow and hit it, so I cut that out too, along with some of the upper inner part like you did.
didn't take too long, there is a hole there now from the little part I cut out in the bottom, but some seam sealer plugged it up.
I'm running a 28x10.5S et drag, which is a bit taller then the regular 28x10, might be why I needed to do a little more. Looks good with the big tire on the car, with a stock sized tire it would probably be noticable though.

How come you had to do so much clearancing? I put my friend's Bogarts on my car with the same tire and it didn't rub at all. I did do some minor hammering previously to the inner area by the LCA for my street wheels with 315s but no cutting or trimming or anything. I have a Camaro but i always thought the T/A's had more room in the wheel wells

You may have cut enough already. How fast are you expecting the car to go mph wise? If it's gonna be under 130, you probably will be ok. with what you already have done. I did more because I'm expecting to see 140+ this year, car went almost 139 the first day out with the nitrous on, now the car is 200 lbs lighter, probably maks anther 20 rw n/a and has gearing that should give it a bit longer legs.
With what you have already done, I'd guess you will be o.k., I'd take it to the track like that, have someone look at the tires after doing a good burnout (or test that on the street somewhere remotly LOL) to make sure that they didn't rub at all, then maybe make one pass to the 1/8th and get out of it, make sure they didn't rub then go for a full run.
Or test it out on a dyno somewhere, figure what the absolute best mph you think the car will see, and run it up to that on the dyno.

I never cut off anything, I tied the plastic back in the rear with a zip tie and just beat the front a little with a hammer.
The 10.5x28S tires are a little taller than the regular 10.5x28s and they will rub a little when they are new on mine, after 10 passes they dont rub anymore. I think it rubs mostly doing a burnout to be honest. Depends how low the car sits also.

I trimmed to be on the side of caution. I once saw a car have a tire rub, and it cut the tire down when it happened... needless to say the end results weren't pretty.
I may actually try to fit a 295/60 radial on when these et drag's are shot, I think with the radial I might have enough room for it to clear. If they will, I'm gonna go back to running them.

When my torque arm bent it pushed the tires into the rear bumper and cut them prefectly. What I would do is cut the bumper flush with the peice of metal behind it, and then cut out the metal, then center the wheels. I almost cut down both rear tires on the metal. I'll try and get pics up if I have time. Mine are not cut very far up. It has plenty of room now.

I put these tires on in the last few weeks. Cut some of the inner rear plastic out (not quite as much as you guys did). Took it to the track now I have a DOT cut around the middle of the tire (helps throw the cops off around town
).
Did you all have to adjust the LCAs to properly fit these tires...one thing I havent tried yet.

Exactly why I did more clearnacing. I've gone almost 139 and they didn't rub at all, so I think I'm o.k. with what I did. I did a little more work in the front then most do because of how the rear is centered, but I'm cool with it.
I did bend/cut the metal behind the rear bumper cover a touch, when the cover's off for the parachute mount (will get done as soon as the tech guys tell me I need it) I'm gonna cut it back enough to be 100% safe.

That metal behind the rear tires is what will get you in trouble. When my rear end shifted back the tires easily won the battle against the bumper cover, but I was a few more tire revolutions away from cutting down the rear tires on that SHARP peice of metal. I was doing 120 mph before I realised it was happening too. It was not a stock torque arm either.
