Hello i am looking to improve the handling on my mk1 focus 2.0. I was thinking

Eibach and Bilstein B12 Pro-Kit Suspension
Eibach ARB kit
ST170 alloys and brakes.

Was wondering about spacers? What size? and also how good are strut braces?

Its going to be used on the road, and occasional trackdays. Do you think this would be a good setup. Would you add anything? Thanks
