[Z06] New wheels/tires- lowering question

I would like to see a picture of this car from the rear to see how these tires look. How wide are these. I have 18x11's and was thinking about just a 305 untill I saw this post. I'm thinking now I could go with a 315.

Wanted to show off my new wheels/tires & brakes. Plus I had a question about lowering. With my old wheels/tires, the wheel well gap looked good, but with the new setup it looks like I'm 4 wheeling. Looking at the pictures, how much lower can I go before the suspension travel makes the tires hit the fenders? I thought the car had been previously lowered, but now I doubt it.

This is probably an issue that is already resolved but you can drop that car all the way to the point of just being able to slip one finger in between the fenderwell and tire; I wouldn't go that far because the ride quality sucks but you can. I currently run 19x11 on the back with 325/30/19's and my car was all the way down on aftermarket lowering bolts. I have z06 leaf springs and Bilstein shocks and I had no clearance issues. I bought the car lowered that far and with those wheels; I changed the springs, shocks, sway bar end links, sway bars (c6 z06 front & back), and I raised the car to get the fender off the wheel. But long story short, you can lower the living hell out of the car without any rubbing anywhere.

OEM suspension is soft and allows alot of movement, increasing the chance that you'll make contact.
Also - lowering on OEM bolts and dampers makes the car ride more rough.
Also - lowering the car too much negatively impacts camber curves, suspension geometry, travel and comfort.
I have G2 coilovers and ended up raising mine back up a bit for all the reasons above. Keep that in mind.

I'm on stock bolts, and Bilstein's that are made for a lowered car. I don't want any lower as the car scraped a fair amount already and the front air dam is 2.5-3 inches of the ground.
My front tires rubbed the brake cooling ducts when in a turn, had to trim 1/4 inch off them. Also the rears would touch the rear ducts on the side walls. Had to remove the ducts. Now the side walls will barely rub on the frame rail when in a hard turn (side wall flex). I think changing the alignment in the rear to have 0 toe verse the sligh inward toe will fix that. Normal driving there is zero issues.

Your front looks to be stock height. I run 275/40/17 which is slightly taller than your tire. Gap looks similar. The rear is hard to tell. I doubt it's lowered. You would have to measure.
I would not run 0 toe in the back. It will get squirrely under acceleration. You need some toe in for compression in the rear.

It already gets squirrelly" under accel, lol But I know what you mean. Realistically I need to get a 5mm hubcentric spacer and some arp studs to "fix"it. The car sits slightly lower that the pic, after settling. I have just barely room to fit one of the Harbor Frieght race jacks and a piece of 2x4 under the car, if I put the 2x4 under the car first in the jack puck location the slide the jack under. I couldn't imagine it going lower and not destroying the under side of the car.
