I'm thinking of buying a strut tower brace bar for my 03 cobra and i have a couple of questions.

1. Do you have to drill additional holes to install this? If not which one?

2. Which one do you recomend?

I guess thats three questions but oh well.

 

find one that you like and buy it. There are so many out there ya just have to shop around.

 

Yes on your 03 you'll need to drill holes. Most of the strut bars are real similar. Steeda has one that comes in a higher strength alloy..I might get that one if I was getting one.
I got a BBK strut bar for $110. It does the job.
