So I'm trying to get front calipers just to make it to the end of summer (when I plan to trade my 99 conti in).

I came across these cheap brands;
RAYBESTOS,
AUTOSPECIALTY/KELSEY-HAYES,
NASTRA,

Any suggestions which to pick?

You are refering to brake pads, I will assume. Does not matter what brand, just note the car came stock with ceramic pads. I recently installed new brake pads and rotors all around. I bought Raybestos ceramic pads and rotors only because they were in stock. The new brakes are working out great, not one noise out of them.

I just put some raysbestos thermo quiet on the other week since they had up to $35 rebate if you got both sets or around 15 for 1 set. I liked them since they are 1 piece pad backer dampner all together. They are ceramic for the conti.
