C4 Lowered more than 1 1/5inch and aggressive alignement ??
Are any of you having your front tires rub into the fender well/hood area due to your aggressive alignment and being lowered more than 1 1/5 inches.
Mine has ZO7 suspension, is 2 inches lowered with 275's up front and with 2.2 negative camber, my front tires touch the fender well under the hood once in a while and are slowly taking a little black off and I am worried it will eventually get in the SMC.
Anyone else have this issue?

So if it's hitting the fender LIP you may be running the wrong offset wheel or you are lowered too much. Neg camber is fine as it moves the tire away from the fender lip.
I ran original GS rims on my 1996 LT4 Coupe, lowered as much as stock suspension allowed & put some big azz tires on with no clearance problems. Can you post a pic of the car & how much it's lowered?
What is the offset (it's stamped mon the back of the rim if it's GM?
You may need to flare the fenders if you want to go really low.

There are limits you know....
We had the same problem only worse running 315's on the front of our BSP car.. You can only lower it so far or you start to hit things. The only thing you can do is use smaller diameter tires up front (not adviseable) or raise the car up a bit.
You can only lower the front until you hit the innner fender liners and you can only lower the back until you run out of travel and hit the bump stops. Our experience was jack it up so that the hitting was occasional in the front and that was about as good as you can do. Putting stiffer springs on the front won't work because it will unbalance the car, to where you need stiffer springs on the back, which causes the back end to jack, so you have to soften the rear bar, which is like chasing your tail.

I am wondering if the alignment with the lowering is causing the clearance to be too tight to the LIP of the hood.

I don't think alignment is the issue, you are too low for the amount the suspension wants to move.
You need to raise up or stiffen the hell out of the suspension so it doesn't move much. I'd go with the former & not the latter.
Happy New Year.

What doesn't quite make sense is that the front end is rubbing with the stock height pads under the spring. That shouldn't be happening. Does the car have the factory shims under the front spring rubber mounts where it mounts to the chassis? Usually there were two of these under each front spring mount and that will give you about a half an inch more ride height. If you were putting in the springs and wanted the car low, you probably didn't put these in, so that may be part of it.

That's the problem froggy, if he stiffens the front spring it will push like a pig. If he stiffens the front spring and then stiffens the rear to match the front, it will jack in the back like an old VW. There are limits you know....

If the center of the spring isn't touching the chassis, then they are one for one. That is, 1/2 inch of spacers will give you 1/2 inch of ride height. If the spring is touching the chassis then you get more, so it depends on where it is now.

Thanks again,
