So ended going for the 2007 Endeavor front brake swap on my 2003 GT Manual. Gotta say it made a massive difference! Going from single piston calipers to dual calipers. Here I'm going to show you the before and after with parts list and link. All in all total cost around 240$
First the before and after pics.
Before:

After:

The Caliper, Bracket, Rotors I used:
(I used a 2007 Mitsubishi Endeavor as a reference car)
Callahan CCK03982 [2] FRONT Premium Original Calipers + [2] Drilled/Slotted Rotors + Ceramic Pads + Hardware Brake Kit Amazon.com
(Also I think these are out of stock now but it's a good basis to go off of)

Now I tried the pads that came with it and they sucked.
Ended buying these:
[Front] Max Brakes Carbon Metallic Pads TA029651 Amazon.com
Turns out they're rebranded pads but work flawlessly. No horrific smells, no brake fade, consistent grip.

Now for the install it's the same as installing any other brakes. They bolt right up to the factory mounts. Just make sure you bleed it all the way through and have some spare brake fluid lying around to bleed it.
Only thing I did different was remove the rear dust shield.

I've been driving on these for about 2 months now and there's been absolutely no issues.
I also Drive decently aggressively and take my Eclipse out on mountain roads on the weekend and really punish the brakes. So far they love it and want more.

P.S. this is my first long post on this site so take it easy on me. I think I posted in the right section.

Question--Are you using the Eclipse master cylinder ? If so, how is the pedal feel ? I have done this kind of upgrade on a couple of motorcycles. Sometimes you have to change the master cylinder. Sometimes you don't. ...J.D.

If anyone is looking for an easy upgrade, I have some original dual piston front calipers that came off my 2000 GT. Located in Cali so shipping would be the biggest issue but could throw them in a flat rate box....

Pedal feels just the same honestly. Maybe a tad stiffer? Doesn't feel like the master cylinder is struggling at all. Feels like there's definitely a lot more braking power at higher speed.

Should be OK then. The problem arises in swapping calipers when the ratio between the master cylinder fluid volume and brake caliper fluid volume is changed significantly. Apparently this case there is not much change. Cool ! :cool:

If there was issues with the master you would have heard it from the people that use the EVO brembos on the 3G. I’ve known of people using the 3G master on 1g and 2g brembo upgrades so are masters are pretty well designed.

This. I went from 4cyl small front calipers and rear drums to Evo 8 four piston fronts and rear two piston caliper / disk swap using the original master cylinder and proportioning valve. Zero difference in pedal feel and huge increase in braking power.
