Do you mean you need the 5 lug hub conversion first, or brake upgrades that will fit 5 lug hubs you already have?
Either way, you can look to the first generation Eclipse. That is where the 5 lug conversion comes from. Complicates it a bit if you want to retain ABS and the the VR4 is a 91.
Otherwise, if you have 5 lugs already, look for brake kits that fit the Eclipse (keeping in mind that all VR4s already have the larger 2 piston calipers that were used on the 92-94 AWD models).
Many make their own kits, with Mustang Cobra rotors and 3000GT calipers, or Cadillac CS-V calipers, or Evo Brembo calipers, or...the list goes on.
