[V8] Fw: UFO Brake Conversion

I feel like I have to throw my $.02 in here.

I did the G60 conversion and I must say, at the time, I was glad I did.  
Whatever merits the UFO's had when new and in good condition, were lost when 
they warped, which they always did.  There are few things that are more 
annoying than driving in a luxury/sports sedan that shudders everytime you 
brake.  If the warpage is annoying, you can bet the pulsing coming from 
inconsistent friction is degrading performance as well.  IMHO, the UFOs 

Since changing to G60s with metalmaster pads 60,000 miles ago, I have had no 
warping issues at all, and I am working on the same pads/rotors.  Trust me, 
I drive my car hard, and I drive it on hills.  If they were seriously 
undersized for the car, they would have worn out tens of thousands of miles 
ago.  For example, the Chrylser Town & Country my wife drove had seriously 
undersized brakes--they wore out every 10k-15k miles!

As for performance, take a look at BIRA.  They tested a G60 set up against 
UFOs and the G60s stopped the car faster.  Now, they hem and haw about how 
the UFO set up was old and tired--what does that mean?  The only thing I can 
imagine is that the rotors were warped--but that's true about practically 
every set of UFO rotors out there.  They warp--the newer ones are better, 
but they all suffer the same problem.

Will the G60s fade more than the UFOs?  Probably, but not by much.  This is 
total speculation here, but I would imagine that with that cover on the 
UFOs, they retain more heat than a g60 set up (hence, the warping problem), 
so I'm guessing that the difference is not as big as some may claim.

Lest anyone acuse me of being a G60 fan, I'm not.  I just think they are a 
better option than the constantly warped UFOs.

A better option would be to go to a BIRA set up or a Wilwood set up sold by 
RPI.  BIRA makes a kit for the UFO hubs which will allow you to 
significantly upgrade the braking performance on the V8 without have to 
change out the struts etc.  Your money goes to buying nice Porsche calipers 
and new rotors, rather than some rusty crap front suspension off a car in a 
junk yard.  You have to upgrade to a larger rim, but a BIRA brake sytem on a 
V8 with wider/larger rims would give far better performing car in every way 
(except snow traction).  The RPI/Wilwood set up will out perform the UFOs or 
G60s as well and allows you to maintain a stock rim, but I believe it only 
works if you've swapped out the UFO struts etc. for the G60s.

I don't know if AudiConnection is still doing it, but they also designed a 
Wilwood Superlite solution which replaced the UFOs and fit under the stock 
rims.  You might ask Keith if they still offer that solution.

In short, there are many options out there now, which were not available 
when I did my g60 switch.  I would explore them if I were you.  If brake 
fade is a major concern, then I don't think you should be looking at either 
the G60s or the UFOs.  If greater performance is not a concern, I would 
still go to the G60's and kiss the headaches associated with the UFOs bye, 
bye forever.

Just my $.02--take it for what it's worth.
