Disclaimer: I did not look at the parts you listed.

I am pretty sure the caliper mounting bolt pitch is not the same. Are you expecting bolt on or with some adapter brackets?

Other things you have to consider, since you mentioned buying brackets and calipers only:

Thickness of the brake rotor makes a difference with Wilwood calipers. they add spacers to adjust.

Diameter of the brake rotor also makes a difference. The mounting brackets they sell are likely specifically designed for the rotors in the kit. If you intend to use stock brake rotors, their parts may not work at all. Ask questions before you commit any money.

Last comment, the intention for their kits is for drag race braking (weight reduction), not road use. The calipers may not provide any improvement in braking for you used in street application.
