For those that don’t know, GM in their infinite wisdom has fitted smaller brakes to the first year’s new-gen GTO - even though they used Corvette-sized calipers. So now I’ve taken the opportunity to rectify that situation, by swapping out from the '04 to the '05-'06 front brakes… Here’s a comparison of the “new” stock and my old slotted rotors: ![http://farm4.static.flickr.com/3273/2596177005_aa2f1d8042.jpg](http://farm4.static.flickr.com/3273/2596177005_aa2f1d8042.jpg) If you doubt the size, here they are side-by-side: (and for those that are curious - it’s 320mm vs. 296mm.) ![http://farm3.static.flickr.com/2268/2597009204_4a0a23a3d1.jpg](http://farm3.static.flickr.com/2268/2597009204_4a0a23a3d1.jpg) And the new calipers (I couldn’t resist a little customization, but FWIW, it is OEM-style): ![http://farm4.static.flickr.com/3201/2596178271_a826d1d7cb.jpg](http://farm4.static.flickr.com/3201/2596178271_a826d1d7cb.jpg) All that, and a new Russell braided stainless line, and it’s bleeding time… ![http://farm4.static.flickr.com/3106/2596180209_7cdd933ab3.jpg](http://farm4.static.flickr.com/3106/2596180209_7cdd933ab3.jpg) Hopefully, they won’t warp as badly as the slotted rotors. And now I have to go swap out the rear lines, too. ---

so just the 05/06 rotor is needed, nothing else? ---

> [@maybe\_memories](#): > > so just the 05/06 rotor is needed, nothing else? A couple things are needed: '05-'06 rotors, calipers, brackets and lines, and shims/sleeves to fit the brake bracket mounting bolts (14mm on the '04, 16mm on the '05-'06). I also had to remove the dust shield to get the brackets to fit - but it was rusting off anyway. ---

You test them out yet?? I have a '97 Grand Prix…I put a pair of larger rotors/caliper brkt. from a Impala police package car) Put on some Hawk (street pads) and flushed the brake fluid with some DOT4 syn. HUGE difference. When I’m doing a WOT run, I brake hard to get downto the speed limit…watching the speedo take a dive is almost as surprizing as the accel. Nice Write-up:tup:
