UPDATE: I've changed my 'light-weight' rotor selection
A couple of years ago, I changed out all my rotors to stock, 9.5lb Solestice,
rear rotors. Yes, I was using these on the front, also, with modified brake pads.
I ran these for at least a year, with very good results.
But, last year, after searching to see if there was a better setup, that was still
as light, & easier to maintain, I have put together a better combination.
1st off, I am now a firm believer! in the Centric brand of brake rotors, &
only use this brand on all of my vehicles.
On the rear, I am now using Centric part# 120.40040 weight 7.5lbs
This is a stock, 2012 Civic SI rear rotor.
On the front, I am now using Centric part# 120.40021 weight 11.5lbs
This is a stock 1996 Civic front rotor.
With both of these rotors, you can use the stock HHR SS pads.
Both have 64.1mm hub size, & need to be increased to our 65.1mm size.
Easily increased with a Dremel tool.
Both need lug-holes drilled for our 5x110 size.
In my case, I'm still using my 4x100 hubs, during the 'racing' season,
& only need to re-drill the rear SI rotors, as they are 5x114
But, I do have another set of these rotors, that I have re-drilled for 5x110,
that I use from December thru April...
This can be easily done, with a hand drill.
The front rotors need a 3mm spacer, between the hub, & rotor.
Easily gotten on E-Bay.
So, I 'm still saving 100lbs with my rotor/wheel/tire combination,
over the stock HHR SS rotor/wheel/tire combination.
Stock HHR SS wheel/tire = 50lb
My 15"x7" Enkei wheel/street tire = just under 30lb
My 15"x7" Enkei wheel/slick = 20lb

Excellent Dave! I will use this info when converting my brembos so I can run 15" slicks.
Question, how can you be sure the rotors will be "centered" if using non-precise tools such as hand drills and dremmels to modify bolt pattern on the rotors?

By using a dremmel tool, it is very easy to 'sneak-up', 1mm by test fitting, with no issues at all.
With the rotors, as with all rotors, you have a 'loose' fitting, which means that 'close' is good enough, no need to be perfect with them...
it's the hub center-bore of 65.1mm, that needs to be 'spot' on.
