I have 14” rotors, can I assume these require 15”??

yes the SKUs are for 6-pot brembos.

Do you need spacers to switch from the 9.5 to the 11? If so what size? Do you have longer studs too, and presumably open lug nuts…?

Highly depends on the wheel offset. An 11" wide wheel with around 24-26 offset will not need spacers or longer studs or open lugs.

Do you need spacers to switch from the 9.5 to the 11? If so what size? Do you have longer studs too, and presumably open lug nuts…? So many questions with four wheels…

You need camber to stuff the front 11" wheels under the fender - camber plates specifically because you need the room between the strut and fender which camber plates can give you.

Then, you need either
1) specific 11" wheels with ETs for the front (ET~26) - these will fit w/o spacers, but I only know two manufacturers who make front-specific 11" mustang offsets (without going full custom) - Apex is one and I forget the other.

OR 2) common 11" wheels ET~50-52 which fit the rear on our cars, a 25mm/1" slip on spacer, and extended studs which are at least 1" longer than stock - ARP makes some, and you can buy Ford hubs with these pre-installed, or just install them yourself.

OPMustang.com is a good source for studs and spacers, and the guy is very knowledgeable about and has been a great vendor to work with.

The advantage to 2 is you can freely rotate all four corners because they're all the same wheel offset and tire. With 1 you can't rotate front to rear (not everybody cares about that and you save some money not buying studs and spacers.

There is so much to this… motorcycles are so much more simple.

Most are still new in box. I've settled on 19x9.5 (all-season and PS4S), 19x11 and 18x11 for track work. I have a pile of take-off Pirelli DH slicks that can fit the 11" be it 18 or 19 and Supercar3 and Cup2s aplenty to abuse.

what is the Pirelli DH 19 size that fit ?

Porsche Cup runs 18" inch tires I'm asking for 19".

SOrry, I meant to type Lambo Cup. The Trofeo R comes in 19"

But I also have the 'standard' DH slick in 18" and 19"

Thanks 305/690/19 should fit. Very useful will need to look around some tracks.

You should also look into the GT350 swap. Very easy and cheap (comparative with the PP/Bullitt kit) and has some inherent benefit over those in the caliper and pad design and also bigger rotors.

The ones I’ve seen are similar in price, unless I missed something?

what specifically is the advantage of 11s over 10s?This seems like more work than getting a 10 to fit, is it worth it? Why/how?

You're probably looking at the whole "kit" from a vendor that are usually has more expensive.

Buying just the barebones from a dealer or Ford parts vendor is cheaper.

I bought the whole front end GT350 kit for under $1k. Could even be done for a few hundred less had I not chosen to do the studs and ss lines and re-used the existing hardware. I went with the studs for easier pad/rotor swap at the track, not something that's needed for a street car.

You get a wider tires, for a track car it's very beneficial to fit a 305-315 tire over a 275-285 especially on the front of a nose heavy car.

It all depends on what you want to spend, but for him I went with late model restoration wheels. Great budget buy with light weight rim.
