I did two-piece stoptech rotors on my Viper. The solid rotors on those were 27lbs each wheel. The stoptech rotors are around 17.x lbs each. So I saved 10lbs per wheel, its a huge difference in rotating mass. I improve my MPG, not kidding and feels a lot more agile having lost that weight. The car isnt working as hard to rotate all 4 wheels!!!

Pros: significant weight saving, improved agility, better MPG

Vehicle: Dodge Viper

I did mine pretty early solely because the OEM rotors were wearing like a vinyl record. Both the pads and rotors still had plenty of material—it was just a bad wear pattern. I went to Girodisc pads and rotors and have had them on happily ever since.

Pros: happy with Girodisc

Cons: bad wear pattern

I used StopTech slotted rotors (not drilled and slotted) and semi-metallic pads on my 2006 Lexus GX470. Obviously I've changed the brake pads a few times but after 200K miles (yes, that many) my rotors are still in excellent shape. I will not buy anything else, ever

Pros: rotors still in shape

Vehicle: Lexus

Mileage: 321869 km

All brake discs are now StopTech Black series one-piece, no detriment to performance vs the ATE stock two-piece, the upside is no going orange on the bells or edges like the stock discs do, pads are still PFC Z-Rated and fluid is ATE Type200, no obvious fade for fast road use.

Pros: no obvious fade

Cons: no detriment to performance

Vehicle: BMW
