Who makes a kit or what size to I need to put better Brake lines on my 07 GT both front and back??

 

Earl's.

Do a google search for Earl's Brake Lines and you'll find them.

I know quite a few people who are running these brake lines and are very happy with them.

They are much cheaper than the Steeda brake lines too.

 

The Stoptech brake lines came highly recommended to me by other autox and road racers. I've used them on my last two mustangs with no issues.

 

Goodridge makes a set of stainless ones.. I have a brand new set I didn't use since I changed my whole brake setup on front and rear. If you are interested let me know

 

I have the Earls in stock, they're $111. Teflon with stainless steel braided lining. They're DOT approved, pretty nice and easy installation.
