[V8] Brake Upgrades?

Wed Aug 4 13:54:10 EDT 2004

Point well taken.  Increased unsprung weight and increased rotational
mass (bigger-heavier brakes and heavier large diameter wheels) can
really affect the performance of a car...  Perhaps there is some merit
to the wildwood 15" setup (a compromise between to evils)...

BTW, I was curious to how much my Aero style wheel w/ tire weighed, so
the last time I had it off the car, I weighed it - 42lbs combined.  I
think that is pretty good, right? (don't tell the wife I used her
bathroom scale)

I just discovered that Alex's site sells the RS2 calipers - FYI

I don't know Jeremy (truthfully), but I seem to recall a post by Keith
after 
he developed his wilwood set up that compared the G60, to the Wilwoods
to 
the UFO and his conclusion was that the Wilwood set up outperformed the
UFOs 
slightly and both outperformed the G60s by a wide margin (in terms of
fade 
etc.).

Certainly, whether the Wilwoods can out perform a properly set up UFO is

open to debate, but at the risk of putting words in Keith's mouth, I
think 
Keith would say that the Wilwoods are a definite, significant
improvement 
over the G60s.  Remember that braking ability is not just dependent on
the 
swept area by the pads, but also the cooling efficiency of the calipers,
and 
I believe the Wilwoods are vastly superior to the G60s in dissapating
heat.  
I think Keith's original rationale for going with his set up is that
NASCAR 
or some similar racing group was limited to 15" wheels and this set up
was 
tried and true on the race circuit.  With the Wilwood set up, you also 
lighten the front end significantly and all the replacement parts will
be 
cheaper and easier to find when maintenance is needed.

In short, if I was sitting there with a G60 set up, I don't know if I
would 
rush to retrofit my car (at considerable cost) to an obsolete and
expensive 
set up on the belief that there were no other viable alternatives out
there.

Just my $.02
