Here you go, I snapped a bunch more photos.Vanes are e-coated as well. Hope these rotors don't rust like my OEM.
Just noticed the drilled holes on fronts are not as tapered as the rear. Not 100% match, but I doubt anyone would notice once they're mounted.

@TXMAG Sure thing! Definitely will let y'all know my thoughts about these rotors. I'm not your typical driver though, I work from home so I never really need to drive anywhere. The GS sit in my garage for most of the week. I only take it out on weekends - maybe put just 50 miles on it per week. Being in Southern California, we don't get harsh weather or salt on our roads, so I expect the e-coating to last a very long time. It is rated for 400 hours on road salt conditions . I don't expect any cracking either as I don't drive aggressively and never track the GS. You can go with slotted or plain rotors if you're concern about cracking. I have aftermarket 20" wheels, so I wanted a certain look with drilled & slotted rotors. Centric/StopTech makes quality stuff, I'm not too concern about any problems. If these don't squeaks and produce low dust, I plan on getting another set for my 4Runner.

All done
The fellas at Impex Motorsports did a great job on my brakes. Anyone in the San Gabriel Valley area should hit them up for any suspension or brakes work. Love how the Burnt Copper gives a bit pop to my wheels and drilled/slotted rotors looks great behind the Maverick. I have a tiny bit squealing on front passenger side, but I think that should go away once the new ceramic pads are properly embedded. Also lowered front 5mm to match rear better.

Here are the weight of OEM rotors if anyone is interested. 2pc is of course lighter.
Initial impression of the StopTech rotors and Centric ceramic pads...squeal..squeal..squeal!
I'm getting lots of squealing from 5-0mph. If I stop hard, squeals very loud.
Already did a few 60-20mph runs in hope of bedding in the new pads, it's not helping.
Is this just how ceramic pads are, they squeal a lot? Hope they get quieter, else I'm yanking them out.
Also I feel initial bite is less with these than OEM. May be just my imagination.
Looks great, but so far not impressed with their performance.

Weird that you're getting a squeal. I've run the same posi-quiet ceramic pad/premium rotor combo in a lot of different vehicles and never had that issue. I'd pull the pads from the front and check that some sort of lubricant was used on the caliper pistons and shims as that's most likely where the noise is coming from if it's a constant low-speed issue.
This is my lubricant of choice for that task: . I use this stuff for brakes, lubricating seat/window tracks, and as a di-electric grease. It's magical.

I think no1 had find the right combo to fix the squeal. people have tried the ebc rotor and it still squeal. I guess we found the answer that stoptech rotor squeal too. I tried oem 2 piece rotor with posi quiet and it squeal. waiting for some1 to find the right combo to fix the annoying squeal noise.

Got some Akebono ceramic pads for the front. If this doesn't fix the squeal, I give up!
This damn car is so picky with front brakes. I got some Centric rotors and same Centric Posi-quiet 105 pads for my 4Runner. It's super quiet no problems at all. But the same pads on my GS..squeal..squeal..squeal.

Akebono looks promising
Got the Akebono pads on...no squeak at all. Will update after 200s miles, hope they stay quiet. I noticed the Centric Posi-quiet 105 pad material looks semi-metallic very similar to OE semi-metallic. Maybe they shipped me wrong pads?
