Why would you drill holes in your strut towers?
You are wanting the don rome brackets with the GMPP strut bars. They work fine with the brackets. I have read over on club gp that the ZZP strut bar has fitment issues.
speedbuilts can be had for under a 100 nowadas. theyre a legit design, mount to all 3 holes, and strut bars are a compliment more than a drastic change in handling.
where do I find speedbuilts? I google the name and the website comes up as "coming soon"
