The 200q20v weighs 3,600lb and has, in stock form 50 more HP; Ben's
new purchase probably has another 50-60(dunno how much power SJM's
chip makes exactly) going for it with the chip.  You're saying it's
an "upgrade not a downgrade" to go from UFOs to G60's for such a
heavier, powerful car?  It's a DRASTIC reduction in stopping power;
you're dropping from a 12.2" rotor to what, a 10-something?

Half the reason the UFO rotor weighs so much is because it's so big
and it's very thick; that weight means thermal capacity.  If the
rotor ring weighs twice as much, it can absorb twice as much energy
for the same temperature differential.

>, easier servicing

You've obviously never worked on a UFO-equipped car.  Pull a clip,
one pad pulls out in your hand.  Undo the torx screw on the rotor,
now the rotor comes off(especially easy when the pads are worn).  Now
you pull the second pad off.

   It's EASIER to 'service' than a regular caliper, because you don't
have to undo a carrier bolt or anything to change both pads and
rotors!  In fact, the only tools you need are a torx driver and a
pair of pliers to push the piston in.  No wrenches needed.

Then let's note that it is a single piston, whereas the G60 is
double.  Which means that the only other servicing one would
do(replacing seals and boots) is twice as much work.

>much less unsprung weight

Except the stock wheels weigh 15lb apiece, so it's not really an issue.

>And easier wheel fitiment.

Wheel fitment is NOT a problem on 200q20vs; plenty of wheels fit,
more in fact than do a regular type44.

...which pretty much negates the cheaper rotors, doesn't it. Not to
mention all the labor involved in swapping the struts etc negates the
(false) claim of easier serviceability on the G60s.
