[W126 Coupe] Brake Pads

[Jonathan Hodgman]

Hello Alex,
Yes, very different conditions as well! Road Atlanta is fairly long, 4.088k.
My brakes were OK aside from the one hard stop from from 230 kph down to 80
or less kph.  Right before this run is the 2nd hardest braking point on the
track.  Brake fluid was about 20 hours old when I went out;-)

To be honest, the car doesn't really understeer..  I have switched all my
springs for fresh H&R's, running 2 nib in the front, 3 nib spacers in the
rear.  I'm using Bilstein HD shocks all around.  The next time I go out I'm
going to add spring rubbers to the shims as I'm getting a bit too much
compression on the drivers side.  What tyres are you running?  I was using
Pirelli P-Zero Corsa's 255/40/17's.

Are those tyre pressures hot or cold? I was running 2.75 bar in the front,
2.85 bar in the rear.  I found in raising the rear above that caused it to
get a little loose..

I've have heard differing opinion on running a thicker rear anti roll bar..
Some say it will upset the handling, others say it handles much better.

Jonathan
I know one fellow down in AU actually managed to double up on the rear bars,
and he was thrilled w/ how the car handled.
