it seems to me that brakes are probably the most common modification
on a 1600, other than installing an L20B...
Those who follow the list closely will have seen terry's comments about
outbraking soobies and stuff and also my comments about his challenge..
well i don't want to be the one that misleads any of u younger datto
drivers about this very important area so here we go...
Fact:
A car will only decelerate as long as the tyres hold the road..
if the cars are identical they should slow down at the same rate..
Standard brakes are perfectly alright for standard cars
and standard drivers
i have no doubt that the std brakes will perform as well as all these big
brakes - for the first time - after that the fade gets progressively worse and
after 2 or 3 hard stops the std brakes fade to nothing..
enter 2 piston calipers.. this is where it gets tricky.. this
upgrade will resist fade for longer than std brakes because of bigger disc
size and more clamping pressure from the twin pistons
The major advantage of discs on the rear is that disc brakes generally
get rid of the heat more efficiently than drums - so u would naturally expect
less fade..
The advantage of vented discs is that they dissipate heat more
efficiently than solid discs, therefore less fade.
For a car used solely as a road car this set up (ie r31/240k) is probably
close to perfect..
If u go racing u will be looking for 4 spots and vented discs because u
have to keep outbraking the soobie ALL day - not just the first time.
i need the bigger brakes because i do go racing a bit and also i tow a
motor boat regularly.
I had a race from the top of Cunningham's gap in sth qld all the way to
the bottom (its an amazing twisty downhill road that seems to go on for
ever) - against a 450 mercedes sports ( i was towing the boat at
the time) He ran out of brakes about halfway but mine kept pulling up
perfectly at every corner.. i love doing that to guys who spend so much money
on 'image' cars!!!
cheers mick
PS don't forget that bigger brakes and discs increase your unsprung
weight and will definitely adversely affect your handling but thats another
story.....
