Hi, I want to know what are the biggest brake discs made for the gs 400, And were I can buy them? example 18" 19"

 

I don't think you can buy 18 or 19" brake discs.....try the tirerack to get the answer. but that size you did mention you couldn't even get them on a Porche Carerra GT!

 

hahaha, 18" and 19" brake rotors, damn, what kind of wheels do you need? gotta be 22s

okok, just kidding. if you just wanna stay with the stock calipers, sorry but stock size is the biggest you can get. if you get aftermarket bbk, 14" is the biggest common ones out there

 

he is getting 22s!

GSUnit, the largest I have seen to date was 15" by Brembo (do not know if they fit GS at all). There is actually a special for front and rear BBK from Carson in the Vendors forum 14" fr and 13" rr for 3895.

I think even just a basic 13" kit for the front is about 1800 or so, so this is a great deal.

Remember one thing, BBK requires a certain type of wheel spec, I know you mentioned Niche wheels, I do not think they have bbk spec wheels.

Just a heads up.

 

dam even the Hummer can't fit 18 or 19 inch rotors with 26's...

 

Just a thought but maybe he meant those metal discs that go between your wheels and your brakes. Peolple around here have them. They paint them to match the car and put it behind there rims so you cant see the brakes and suspension. I never knew 18" or 19" rotors existed. Maybe he can chime in.
