I was reading the manual that the F300 came with slotted rotors?
Can anyone confirm this? and if this is the case can I get a pair of slotted rotors and bolt them straight on without any modifications ?

slotted rotors?
Moderator: Tiny
Is a little unclear what came with what... but F310's have ventilated disks and perhaps some F300's
You can't just swap the disks as the caliper bridge is wider for the thicker disk - but you can change the disk and caliper as they bolt straight on.

It seemed like a much better idea when I started it than it does now.

No - perhaps it was "trim" level dependant.... my F300 had solids ( now on the rear so nothing got wasted..... 
rear brakes that WORK ! ) and put ventilated ones on in their place.
Actually can't say I've noticed much difference between the two... but ventilated are theoretically better so....... The Feroza calipers are typical of most small Jap cars, functional but not great - so its a bit hard to tell if its rotor or disk that limits.
Unfortunately the hat diameter of the disks also makes caliper conversions difficult but I havn't given up on fitting some decent 4 piston calipers just yet.

drilled an slotted rotors!
there is a store on ebay its over in the states they make drilled an slotted rotors has anyone seen these an has anyone bought a set?? just stumbled across them anyone got any info??

IMO do not run drilled rotors on a 4WD used off road..... but slots seem OK.
I have a VERY scored rotor to prove it - it trapped a stone in one of the holes and ended up grinding away the rotor and pad in that area.
I've just pickled up a new set of rotors and I didn't even bother with the grooves this time - its just too much of a PITA to have them score up, so I'll stick with plain ventilated.
I'm not saying they don't work - they do for performance systems, just for a genuine off road 4WD not a great idea in my experience
And RDA also supply at reasonable prices.
If you want significantly improved braking then rear disks are the way to go - stops significantly better and feels more stable under brakes. Pity the tires aren't as co-operative in the wet......

Whoa! That's around AUS $205 without any shipping.... and then there's the concern of what happens if they somehow don't fit....chugga wrote:They seem like a good buy!

I've seen DBA slotted rotors advertised for around $129 ea (IIRC?) try ringing around a bit and you should be able to do even better.

i would think even slotted rotors would be worse on a 4wd. it would surely allow much more mud and water to get draged into the friction surface reducing ur brakeing.
slots and cross drilling are for tempreture control at extream breaking.
vented's would be fine any more is a waste. would be better off spending the money on better quality pads/calipers etc

Slots and cross drilling are not for temperature control - the increase in surface area is quite insignificant in the scheme of things and the airflow through the holes and slots is very low - unlike ventilated rotors where the centrifugal airflow is significant.Jacked wrote:slots and cross drilling are for tempreture control at extream breaking.
When the pad is applied to the rotor during braking , a significant quantity of vapor is generated by the pads friction material - left to itself this vapor is effectively trapped and forms a cushion between the pad and rotor. This causes the pad to "float" lessening the braking effect and also resulting in poorer feel.
Slots and holes allow for the release of this generted gas, providing better contact between the pad and rotor.
However as you point out this effect is most noticible under heavy breaking conditions.
