car was not alignable?

Nick is the Ford tech who said he drilled the towers............

Avoid any C/C plates made from aluminum, they may crack. Stick with steel C/C plates, they are much less likey to break.

Also avoid any C/C plates with a rubber bushing at the top - too much slack to maintain consistant alignment through the complete range of travel of the suspension.

JRICHKER is right. Buy quality. Dont use the BBK or MAC plates

I used Steeda c/c plates. Another source is

They have J & M C/C plates for $155.

No, they were being honest with you more than anything. If they were dishonest, they would have done a "toe and go" and then said the couldn't adjust anythign else and taken your money.

If you have bad struts or the car sits uneven due to binding parts or sagging springs or even tires, it might be brought to spec but it still won't be right. The stock strut mounts do have a little adjustment to them, but I do mean a little. I don't like metal drilled out of my strut towers anyways.

So if you have worn out / bad tires, struts, ect... what exactly do you expect to achieve with an alignment?

That was very honest of Les Schwaub. I would trust them. Did you get the free beef?

I see that you have Eibach springs, but what struts are you running? Stock? Brand X worn out? I would suggest putting at least some KYB's in there while doing C/C plates. Not only would your handling improve but so would your ride quality. Every day I see so many cars, and so many ride bad and all they need is struts or shocks. They make a world of difference. OEM shocks/struts really suck because they are usually too soft to make the car ride better to sell it while the bushings are breaking in.

correct me if im wrong but if your running eibach sportlines thats a 2in drop in the front end. if you dont have camber caster plates then the shop was right in saying that they could not align the car. drilling the strut tower? why take metal away from a critical load point for the whole front end. save yourself the trouble and get a good pair of c / c and you shouldnt have a problem with alignments again.
