I have a CUP 260 2009 completely stock. Locking to upgrade my tires and brake pads for track. My tires choice is Hoosier A6 and my brake pads choice is Pagid .

Tires: What is the best size on stock Cup wheels? Do I stick to the factory setup, or go slightly wider?

Pads: I'd like to use Pagid 14s on the front. Not sure if I should keep the factory RS4-2 on the rear, or have the same compound as the front!

I don't know about what's available in your wheel sizes, but for brake pads, I would highly recommend Carbotech XP12 in the front, and Carbotech XP10 in the rear.

I've found that Pagid blacks have very uneven transfer to the rotors and don't handle as much temperature as the Carbotechs.

I know Carbotech are excellent pads. I use them on my ISF and they really take the heat very well.
The thing is I already have Pagid black for the front. I just need to confirm whether or not I need to use balk for the rear as well!

Someone here on the forum was selling used Pagid black . I saw the post two days ago. Can't find it anymore. Could someone send me the link!

I had Pagid pads and hated them on the street. They squealed like a banshee on the street and dusted horribly. I changed over to Ferroto DS 2500s and am extremely happy. They grab great at the track and are quiet on the street. Best of both worlds. I do however have the four corner Big Brakes setup.

I'm not sure how wide are my wheels. Would like to go for 245 if my wheels can take it.
Here's a pic of my wheels if someone could confirm how wide they are on the back.

He is saying there needs to be a ratio of front width to rear width. i.e. if you fit too large a tyre on the rear, you'll upset the balance of the car and promote understeer.

the 235/205 combo works well and will fit perfectly on your wheels. you dont need a 245 unless you have significant power upgrades.
