What are my options. Current setup it Brembos with stnd pads and discs. Recent brake fluid change along with new brake pads all round and disc's are in very good condition. They are now finding it a little hard to cope what upgrades are available. :cheers:

Pads and or two piece disks
2 piece AP disks/bells like BenS1 is running will be available in the new year

DS2500 pads or Carbon Metallics both Stop VERY well... Extra heat form extra friction of course tho.
Consider brake ducting onto the setup.

Cheapo 1.4 base models have clip on deflectors (which I have) onto which you can make them better by adding bits..

yep carbon M. pads are great but i ****ed up my disks with them from the extra heat - cracked them really bad dont know if it is a trade off for the extra stopping power???

It's not the IHI, cos that only lets you get to the speeds you need bigger brakes for slightly quicker. Your chocie is simply a pad with greater friction, bigger pads and discs or more pressure via calipers with more pistons.

TBH in the season of muchos rain i find that the brembo's will lock you up before they slow you down :(

Weather here has been cold (not freezing) but the roads have been dry. List of next mod below. Its the fact the car is having to been slowed from higher speeds in a shorter amount of distance/time.

1. Clutch LSD
2. Brakes (better set up)
3. Aquamist

I've got the same setup as you Gary and as you know I don't drive THAT hard. Even still, I've just warped my discs, so I can see why you need better on your car.

I'm not doing much to mine from now on, but an LSD is one thing I would consider :thumbup:

Maybe it's just the fact it's just takes a shit load of mechanical effort to slow down a tonne+ of metal from high velocities (about 2.2 million N for a beezer at 100mph!) :-o

Been speaking to a local fitter and he said he could do a 325ml ally bell setup using existing calipers etc, for a fair price, Me and Addo and looking at this route so may be able to help. Also offers bigger rears on existing calipers (Dunno if it makes a difference tho but looks cool) :thumbup:

Will do Mike, i aint after more power but i am after the peformance i have now carrying on into the summer months and aquamist should help with the summers hotter temps. I had a go on some private road (airfield) and went off the speedo if numbers were available it would have been about 175-180mph how fast in real terms (Gps type) i dont know. I had to get on the brakes quickly and with some force. It was a slightly arse nipping type moment

That'll help fade, but presumably if your using the same calipers and hence pads, the general stopping power will be the same?

are u meaning front or rear??

Fronts should reduce fade cause of alu bell

but if you mean rear then I suspected as much, But it will look cool :hide: but isnt the bias only 10/15% so rears shouldnt really fade?? Plus if the discs are bigger shouldnt they shed heat better?? therefore less fade??

Yes, as I noted it will help fade (with the bells on the front). As you note the rears will do little.

However, what about the dual piston 2 pot rear caliper that brembo fit on the Lancer etc? Maybe if you could wind another 10% extra to the rear and use that, then the front balance under breaking would improve and it would put a little less strain on the front discs and probably stop you a little quicker?

Ref heat shredding, you would have to consider how much more material was in the disc. it'll work better initially as a heat sink, but as for how much it would shred due to the extra width being in a limited airflow is more open.

Ceramic discs anyone? :blink:

That'd be scary! I reckon the Ibiza is over braked at the rear as standard. Before I fitted the Brembos up front, it always felt like the back end was going to come past the front under heavy braking :-o

Just to update: I said I had warped my front discs. I thought I had due to all the vibration under braking, but on checking, it was the rears that were shagged. Just replaced the discs and pads and found that on one side the pad material had separated completely from the backing :whistle:
No wonder it felt scary :(

That's because all the braking effect is all on the front. Unless your locking the rears or braking heaviliy on a corner the rear 'should' be stable. did you have spacers at the time?

I had 6mm spacers, which have now been replaced with 10mm. That said, the Ibiza was never the most stable car under braking was it?

More friction (stopping power) More heat
Brake ducting req'd.

You WILL NOT FIND BRAKES which will be everlasting on IHI'd motors.
consider them consummables.

Reduce fade?
all depends on whats fading....

If CM pads it is'nt pads fading... its brake fluid and boiling, even with 2 piece disks and ally bells.

Remove your ABS fuse and see how much rear braking there is mechanically... it is'nt low iots way too high... (do this on a quiet private stretch of road as you will likely spin out)

I've just replaced my rear brakes with another set of standard discs and pads and it feels great at the mo with them having not bedded in yet! :D
I guess it'll be back to scary when they get some more stopping power after a few miles :clap:

pointless discussion Vern (sorry :( ) as Madmile said he didn't have GPS and at 160 I SERIOUSLY would not believe anything at that end of the dial indicated scale let along aanything beyond it. We all know IHI is fast but that's pretty questionable.

If i get round to it i'll chuck in a few figures just to see if the avilable power is more that that required at 180mhp just to move the required air away from the breezeblock known as the Ibiza... :roflmao:

Agree, Vern - just not an advocate of people trying to out 'mile an hour' each other at very high speeds. Cos it could lead to some nasty outcomes :(

Gearings an issue too.

probably narrow it down to a mathematical ballpark

aerodynamics are no problem IF you have the power - even this thing does nearly 180 in 1/4 mile

mk3 i hear is 0.34. I reckon the speedo over reads by 10%. As going back to my bike riding days and comparing (Blades etc) i reckon the Ibiza was doing 155-160mph real. CC has been off the speedo without much problem i was behind at 160mph indicated and he was going away from me. What amazes me is how even a slight headwind or a tailwind can make a massive diff.

Hitting 160 on the speedo is pretty easy. It seems to get a second wind at 150mph.

My motor was a lemon comapared to others from day #1. best it ever made when Oettingered was 192bhp @ Jabba just before it got torn down for IHI. When IHI'd it did'nt make the same power as Mikes Ibiza from the same (similar) mods.. Post fuel pump problem and meltdown it had some work done to it, ported head and slightly lower CR from piston machining. Still never as 'good' as Mikes (who ported his head big time :D )
It does the bizz these days because I make it...

New motor is in process now, so who knows what it brings.

Fastest ever from me @ Brunters us 160mph.. Need more than a 2mile straight to get Vmax in mine. On a *private* road, on my spare 02A 16v Ibiza g'box (shorter geared) I did rev out in 5th at 7800rpm on a GPS Ipaq tomtom 173mph. Its fecking scarey at those speeds however. :hide:

Don't understand personally. Yuo must have changed everything apart from the block? Now unless the cylinder bores are very slightly staggered or out of angle then....

But saying that all blocks are cast from a similar mould (there must be a master to create those) and then it's a case of reaming the bores (dodgy reamer?)

Dunno.

The bell mount discs and Performance Friction pads from Bill are working excellently. Never had any kind of fade yet.

My biggest concern now if fluid boiling. I've not had it happen yet, but with the grippier rubber I'll be using (And eventually slicks if I can get a catch/breather system to prevent oil surge) it could soon be a real issue (As it is for Bill).

The next step could then be Liquid cooled calipers!!! Bloody expensive, but they should handle anything!

Now, you could always cast some alloys with spokes the profile of an aerofoil. This would suck so much air through away from the brakes you would never have a problem :thumbup:

another thing you could do, and i have seen thi done on a mates 200sx, Some cars come with the metal brake dust covers at the rear. Now what he did was bend these about a bit to creat an air duct which does seem to work well.

Only trouble to also works too well, eg drive down the motorway late at night for say 20 miles in the wet and the discs are then too cold and really dodgy on the first use. can't have it all......

I thought Bill was using ducting now?

So if they do work as a heatsink and not as a fan, then there is still milage in a fan based system I recon (by using ducting as M0rk mentions pusing air through from the front onto the discs then drawing it away using the fan approach)

I would say suck air out of the arch by wheel, as the vented rotors are shaped like ducted fans to suck air in the middle and blow it out the edge of the disk.
I have ducting yes, wishbone deflectors, but need more.

Boiling is only apparent on slicks at maximum pasty.. road tyres they're fine.

I would say suck air out of the arch by wheel, as the vented rotors are shaped like ducted fans to suck air in the middle and blow it out the edge of the disk.
I have ducting yes, wishbone deflectors, but need more.

Boiling is only apparent on slicks at maximum pasty.. road tyres they're fine.

Speaking of which have you managed to get a supplier for the discs yet?
