Within a few weeks my new crossdrilled rotors will arrive from the United States.

Brakepads might be upgraded as well. Does any of you have experience with high performance brakepads like Ferrodo, Mintex or Greenstuff?

I'm not looking at hardcore racingpads that need to reach a certain temperature before braking properly.

Hi, I replied to the mailing list, but might as well post here to, it might help someone else.

I was under the impression that EBC Greenstuff was for fast road use on smaller saloons and hatches, while the Redstuff pad was more suited to larger cars and for light track use.

Also try and find out if Mintex have the M1144 fast road/rally/trackday compound in a pad for your Saab. Supposed to be a very good pad, that doesn't need excessive warming like a lot of motorsport pads. The Ferodos have a god reputation for the more expensive ones in the range, just can't remember model numbers right now.

In my experience (and others) the words "Greenstuff" and "High performance brakepads" are mutally exclusive for Saabs.

Greenstuff might be OK for hot hatches but it's awful on larger cars after a few thousand miles.

BillJ has used Mintex 1144 with success. Both of us have used Ferodo DS2500. I've also used Pagid fast road which are good, but not as good IMO as DS2500. The Ferodos tend to be expensive if you buy them from the specialist Saab tuners, but not so if you can find a decent specialist motorsport
supplier.

I found the DS2500 more fade-resistant for track use, but the 1144 better for road use because they have a good "bite" from cold, while the DS2500 feel ever-so-slightly "wooden" for a while from cold. Both are better than the standard pads, in my opinion, even from cold.

In my experience, even the 'race only' spec DS3000 compound stops well from cold. And boy, do they stop the car...

Only big drawback is that road salt tends to eat them very fast, according to Graham at Trent Saab. Not that I wouldn't be extremely lucky to get more than 10,000 miles out of them otherwise...
Hey, it's that, or 2,500 euro for a set of AP four pots - you pays yer money...

There's another couple too- if you actually do any serious braking with them, as they heat up, they start to shed metal fragments all over your nice alloy wheels, and do tend to eat discs, which is why they're nominally a race compound- because race teams can afford to chuck away a set of discs after one race if need be
.

I might cope with a set of pads per track day, and be prepared to keep a scabby set of wheels, but discs at over £400 a pair, no thanks!!

Bah humbug - actually did one or two emergency brakes with the DS3000's - discs still look like new, no wear ridge yet. My 16" Aero's are clean as anything, too - quite easy to wipe a cloth over them after a drive. I did wax them after putting them on the car, tho'.

Me too. For those '87-on 9000 owners who can't find PowerDiscs, I've been using the earlier (non-ABS) discs, from Euro Car Parts and they're very good. The older discs are 23.5mm thick. The newer discs 25mm, but their regrind limit is 23.5mm and they can then be used again. Since I wouldn't ever regrind the PowerDiscs for fear of losing the grooves, I don't think I'm losing much and I'm gaining a lot.

Now if i was to put something like the ate power discs? and 1144 or even ds2500's (if I can get any of this!) on my 9-5, would this be a good bet as oppossed to making the brakes physically bigger?[/qb][/b]
I got very much increased stopping power on my 9000 from teh PowerDiscs and 1144 pads. As I've said elsewhere, I've found the 1144 pads to be at least as good as the DS2500 for road use, and give better friction from completely cold starts. On the 9000 anyway.

on my old carlsson, i used 'sparco' pads. they were pretty damn good too (after the 1st use), much better than the mintex F171's they replaced (now that tells you when it was...)

The sparco's were really for a B*W 3 series and merc 190's too.

I know the bigger brakes are the better solution, but would increased stopping power suffice for 'fast road' use? [/qb][/b]
The decision depends on how many trackdays you'll visit. Bigger brakes are probably better, but will cost more than upgrading pads and (stock size) discs.

The price difference is enormous
, so upgrading pads and discs will probably get you more value for the money for fast road use.

Real trackday enthusiasts will opt for the bigger brakes.

I agree completely. I'll be going for the bigger brakes, though, for the track days

OK,
I found my old sparco pads box.

It says:-

Sparco Competition Brake Pads

Correction - after the clutch finally succumbing to the 330lbft it was being asked to carry, and deciding that it would be folly not to have the LSD and lower final drive I wanted at the same time as fitting a racing clutch, I'm not in a position to fit big brakes (and the 17" wheels and tyres they require) for some time.

On the bright side, the car Abbott have lent me, while having many shortcomings including the ABS light being permanently on, and hence no ABS
, does have excellent brakes - much better bite than any combination I've tried in my Aero so far. Having had a good look, the front discs appear to be their drilled and grooved iron discs with standard calipers (I'll ask them what pads are in there). Mark E assures me these are virtually identical to the Group N discs from Trent Saab, so these might be a good interim upgrade until I can afford a really good set of brakes.

[Edit] Just checked Abbott's web site and their discs aren't drilled like those on the loan car. I'll have to find out what those discs and pads are, then, because they really are a good combination.

Hello !

I'm using Tar-Ox discs and pads in front (bought them from Speedparts) and I'm happy with this setup. My old discs and pads were totally worn out so you could really notice the difference ! Haven't tried any other setup so it's a bit hard to compare...

I have used a variety of combinations om my '97 9000 Aero including Abbott Grooved Disks and Pads (Mintex I think)& EBC Redstuff Pads both of which are significantly better than standard but still didn't stop Brake fade! Then tried Mobil 1 Synthetic/racing Brake Fluid separating the Brake and clutch systems using a 99 fluid reservoir for the clutch which improved the situation further.

Currently trying Black Max Grooved and x-drilled disks with Pagid pads which seem very effective but noisy and still not an absolute cure for fade.

I supect I really need a big brake conversion but don't want to fork out the loot.

It is intersting to note that when I run 15 inch steel rims albeit with Snow tyres brake fade is never really a problem even in the summer - I have tried. How good are Aero rims at dispersing heat?
