Default Scraping sound on sharp cornerning

As the title says, My car scrapes the ground whenever I make a sharp turn. It is too low to the ground. In my records it says the car was lowered but it doesn't say by how much. Mostly I don't care how much they lowered it, I just want it to stop scraping.
What are a few ways to accomplish this? It has adjustable Koni's on the front. I have them tightened all the way up. Whats the most cost effective way to stop scraping?

What exactly is scraping? Exhaust?

Are you sure it's not just the tires rubbing on the inner wheel well?

Its the plastic "batwing" infront of the tires. Atleast, thats what I think it is.

Stiffer springs..

Quiet a few local 951's and S2's do this routinely at auto-x. Jeeper31 didnt believe me until i showed him a picture of his car going through a slalom.

How expensive and difficult would that be to get? Is that the only option?

Ehh... No thanks.
Seriously, I need some more info, I want this fixed.
Are there any "while your in there" things to do to the suspension if I'm going to replace springs? How much can I expect this to cost to get a shop to do it?

I recall either Car & Driver or Road & Track testing the 88 S and complaining it did that brand new! Sway bars are supposed to stop swaying -- you might start with a stiffer set. Teller set of tires might help too, if you don't mind taller tires. Either or both might be worth a try before digging into the springs, torsion bars, etc.

What do you guys recommend that I try first? I don't think that I can fit bigger tires on there...
The ones I have on the front now are BF Goodrich G-Force 205/55 R16Z 89Y. The rims are 16" Phone Dials.

Are you still on the stock suspension that's 22 years old?

Just looked over my records, here is everything suspension related:
CAR IS CURRENTLY 149,xxx miles
Replaced Torsion Bar Bushings: 113,802
Replaced Rear Shocks: 113,802
Replaced Left Control Arm: 113,802
Installed New R&P : 114,000
Installed New Tierod Ends: 114,000
Installed New Steering Shaft : 114,000
At 114,000 it says "Lower Front Spoiler..?" Maybe it was replaced or something?
At 117,000 it says "Adjust Ride height and align front and rear suspension."
At 117,000 Miles it just says "Tightened Front Suspension"
At 65,000 it also says "Tightened Front and Rear Suspension"

After reading through that I didnt see anything about new front suspension.. Maybe it is original. They are Koni adjustables.. the wrench that goes to them is a little white plastic cap...?

Would the Lindsey Sway Bar be a good idea? They say that it is almost identical to the MO30 option. That would help my swaying issues over the factory sway bar right?

If you're scraping the batwing (the sound is not a tire rub) under hard turns it really might be time to do some upgrades/rebuilds to the whole suspension. Stiffer springs will cure it but if the struts are OEM, then they, IMHO, need to be rebuilt or put in a new insert if yours come apart and are not sealed struts. If sealed, consider the Paragon insert -rebuild kit.

My first DE was with the worn stock suspension, was scrapping my splitter almost ever corner.

Did the Paragon Yellow Koni insert Like ski mentioned, yellow's in the rear and Mo30 sway bars and all is well now.
