So give it to me like I'm 2 yrs old.

The Vantage V8S uses what type of rotors?

The Vantage V8 uses what type of rotors?

 

All V8VS have 2-piece 380mm floating discs and 6-piston calipers.
pre-2012MY V8V has 355mm integral 1-piece discs and 4 piston calipers.
2012-13MY V8V has 2-piece 380mm floating discs and 6-piston calipers.
2014MY-On and GT have 380mm dual cast discs and 6-piston calipers.

 

the majority of the weight is in the rotor. the hat, is also on a much smaller diameter. most 13-14" stock, cast rotors weigh about 18-20lbs. the center hat portion is only about 7" in diameter. its always nice to reduce rotating weight, because at the wheels and tires, its about 1.5 to 2x the effect as if it was sitting in the car as far as acceleration, but at the Hat diameter, for the sake of this discussion, its negligible as far as its rotating effects vs if it was sitting in the car. so, saving 4lbs per corner is not worth getting excited about. handling-wise, its something, but nothing you will ever notice on the street, especially on a smooth surface.

 

And which involves cost cutting?

Which provides better performance?

2-Piece floating vs Dual Cast

 

Relax. You got the best ones.

 

cast usually is most durable. ive seen even stoptech two piece fall apart at the track.

 

 

It would be interesting to see what the purchase cost of each rotor is, I bet the non floating item is much cheaper.

 

^^^^ I'm sure our buddy Stuart could look this up for us.

 

is nice if you get a custom hat , that can use the cheaper outer rotor piece. generally, they are about $200 each, but the hats , made custom might be near $700 each.

 

Are those the wheels in the 2nd and 3rd pics above? If so, then they are the same as mine. Those H&R rear wheel spacers that you have will go straight on, I fitted a pair to my car last weekend, and AM has thoughtfully put a hole exactly where the original studs stick through. Perfect.

 

Yup. Those are the wheels and I was planning on using my spacers. They also fit the old sport pack wheels without modification but just barely. Have you posted any pics of your car with the spacers yet?

 

Hadn't posted any pics until now - this is the car straight off the jack

 

And these are the wheels
