LOVING my A&A Supercharger kit, but after the install my front air dam was so low that the car would scrape on a level highway if I as much as hit a dip on the road! It was getting ridiculous, so I pulled the wheels off and turned the factory height adjustment bolts 2 full turns and went for a drive.
Still lots of scraping. As I drove through town, it would scrape hard on every single intersection, and people would stare. The real icing on the cake was when I stopped, and this older woman came up to me and said: "You're going to have to learn how to drive that car, honey". She is lucky she's not a guy; I would feel very tempted to punch a dude if he said that to me. I kindly pointed out to her that my driver skill does not affect the ground clearance of my car, but if she wants to buy one of her own and figure out a way to drive it over dips in the road without having it touch the ground, there is a Chevy dealership just up the road.
So today I took the wheels off again and turned the factory ride height bolts another turn and a half; they are about bottomed out now, so I can't raise the car any higher. I also took some heavy duty scissors and cut just a little bit off the splitter too. The scraping seems to have stopped, and the height from the ground to the top of my rear fender is 28". From the ground to the top of the front fender its 26". I'm happy that the rake is still there, bu I wonder if this is anywhere close to the factory ride heigh...

What have you guys done to solve this in your cars?

 

Very simple. Take a dremel tool and cut half of the thing off! Since I have a front spoiler I took both of my side ones off and kept the middle. The middle is the only revelant piece needed that directs air into the radiator. This sides are more for asthetics. All my cars are absolutley slammed and I never scrape.

 

Check the big bollas mods 1,2,&3. That will reposition the i.c. allowing for a better fit so the bottom of the front facia isn't "pushed" down... once it fits correctly it'll take the flex out and raise back up, this is how it "should" fit anyway...

 

I thought his mods were for procharger kits, not for the A&A which supposedly was already optimal?
The air dam bolts on to the steel radiator bracket, and all that is scraping is the air dam, so short of relocating the bracket, nothing I do to my intercooler is going to gain me ground clearance I don't think..

 

Gotcha on the air dam part... I knew the kit had it's differences but was not sure on that difference, since Andy's new intercooler design... then I suggest you do as most of us did before the Bollas mods, and use a razor knife and just cut down the center seam of the dam, cutting it in half (top/bottom) as mentioned by vettethret, the razor knife is much easier and more precise, though, imho... But the one mod they should build into their kit is to flip the intercooler. getting rid of 2.75 feet of un needed i.c. piping. these small additions + correct setup, combination and tuning, are what allow some VERY efficient rwhp numbers for me... and I want to pass this shared knowledge along to all my F.I. corvette brothers...

 

Don't forget your alignment if you're going to leave it jacked up.

Agreed; my objective, however is to bring it to stock ride height...

 

youll learn to just get used to it. mine hits everywhere it seems. at first it bothered me but now i dont mind it. it actually funtional and pushes air upward to the radiator i believe

 

I don't understand why you would have this problem after the A&A install and not before. What changed other than some extra weight on the front of the car?

 

Coilovers should help if you are open to that mod.

 

Yes, it is designed to direct airflow to the radiator, and yes it is meant to scrape on occasion and the manual lists it as a wear item. However after the install it was scraping EVERYWHERE, ALL THE TIME. No getting used to that. It would scrape if I took a sharp turn even!

Well there is some weight added to the front of the car; about 75lbs total. This weight is added well ahead of the front axle, so it levers down on the front springs causing more of a drop than the weight alone would indicate.
But what is really significant is that to clear the intercooler piping you have to move the radiator core bracket down by about an inch via aluminum spacers. The front air dam is bolted on to that bracket, so the air dam moves down a full inch as well... That is what makes it want to scrape so much.

Drove to work today and didn't scrape except on 2 steep driveways. I have solved the problem; if my ride height is still stock (that is what I am trying to find out) then I think I found the ideal solution.

 

Coilovers also cost about 3 grand installed. The factory car has height adjustment for free; buying coilovers for just that would be a massive waste of money...

 

Most of the blower guys have cut all 3 pieces 1/2"-3/4". The 2 side pieces come of easily to cut, but the middle piece is a bear to get off so you're better off to cut it in place with a pair of (large) "handy andy" tin snips.

 

Looks like my current solution has completely worked... I am no longer scraping

Current ride height as measured from the ground to the top of the fender is 28"R, 26"F. From what I can gather this is a touch lower than stock. I also removed just shy of 1/2" from the airdam itself, leaving plenty of airdam to direct the airflow.

 

I also got tired of the scraping and raised my 07 back to slightly lower than stock ride height . When I pulled to blower off , the car looked like a 4x4

 

Our cars are front breathers, you shouldn't see a big issue with removing as much as you feel the need to remove... now on a C5, forget about it...

 

Cars are bottom feeders. No air dam no cooling!

 

Very true... But we can't forget that the FMIC does block some airflow, so for us the air dam is a little bit more important...

 

Glad you found the solution. After my ECS install I scraped and still do scrape over all speed bunps. I just got use to it as I never seem to drive the car anymore

 

Snip Snip with a tin snipper, removed about an inch, no more scraping. No problem with heat, its not an issue to cut it.
