As title, can anyone recommend a budget brake upgrade for my Aero on 16" Super Aeros? Better calipers, bigger discs etc.

Seems you can get the 308mm disks and calipers from a 9-5 Aero on the 9000 although decent disks, pads, braided lines and fresh brake fluid will make a lot of difference.

You need a very thin metal spigot machined to centralise the disc and it drilled to suit the 9000 PCD and the calliper supports need cutting in half and welding to the opposite half of the 9-5 caliper bracket to accommodate the 9-5 calipers.
That's the Abbott racing procedure.

Try new fluid first. Makes a decent difference. And use some leg muscle. Servo is not overly intrusive.

Ferodo DS2500 pads are the best brake mod I did, followed by braided lines and Dot5.1 fluid.

Don't bother with 'racing fluid' unless you are going to change it after every race.
It has a a lower wet boiling point, hence it normally being rated dot4 or dot3 even though the dry point is higher. As the fluid ages it absorbes water (its supposed to to stop the inside of your brake lines rusting), so if you put in a racing fluid it's great when fresh, but bad when more than a few months old. Not a problem if you are rebulding the brakes every few months or once a season, but expensive and a faf for road users.

I'm with Beardydave on this. Best bang for your buck is DS2500 pads. You need only do the front. Best to fit new Brembo plain discs as well , they are not expensive. You can get them from BillJ. Note with the pads you need to do a bit of fettling of the backplate to get them to fit. Plenty of threads on here.
The gold std is to fit 9-5 brakes but that mod is expensive

DS2500 / DS3000 / Yellow stuff
Grey iron discs (good standard)
Braided brake lines
Fresh fluid

Go and try again
That's what I used on my track car.

Only comment on DS3000 is that they squeek a bit if not used hard, DS2500 are a bit more forgiving on that. And yellowstuff haven't got the best of reps, have a habit of crumbling even when bedded in as per the procedure.

Having just got to a point where I'm happy with my 9000s brakes I'll throw my two-penneth in.

DS 2500s are okay but they don't last long, have rubbish initial bite so aren't great for the road.

I managed to heat crack several sets of Brembo discs in quick succession. Usually every 10k.

To save money sometimes you have to spend a little more in the first place.

I now have the 9-5 calipers / disc upgrade mentioned above. Much better and not the big money of the proper big brake kits either. A happy half way house between good performance and a big spend.

I've run plain brembo discs with ebc yellowstuff pads on several different makes/types of cars for a number of years and never had anything to complain about at all. Maybe I'm just lucky, but I've never run into any of the issues other people have described. I don't do track days, but I do drive 40-50k miles a year and I drive hard. :)

Obviously bigger brakes would be ideal... but for the road, on my 9k, I found that the standard system, when in good nick (rebuilt/refurbed master cylinder/callipers), coupled with braided hoses, and good brake fluid, brembo discs & yellowstuff pads, is plenty good enough -- even with 350ish bhp. Good bite even from cold, very little fade on the street, minimal dust, no squeaking, reasonable life. All good enough for me...at least for now.

Don't forget, good tyres make a big difference, too!

Get the Brembo pads as sold by BillJ / Saabits.

I found them a amazing upgrade from stock pads. Mine was at 300bhp, and the brakes more than matched the performance.

Yes i'll second the braided hoses as ommony mentioned, massive improvement on pedal feel. I had braided hoses put on the same time I tried EBC Redstuff along with Tarox G88 discs. This combination felt no improvement over standard when cold, dare I say it slightly worse when really cold.
I then went for EBC crumblestuff (yellowstuff) and found a nice improvement although still poor from cold. Get them hot and they come into their own....managed to set these badboys on fire while at donninton circuit in the wet haha! But and it is a big but, every set I used tended to crumble away when passing half worn.

This is now the point I decided enough is enough and get decent brakes on. So, ex-elkparts kit (brembo 4pot with 314mm discs) goes on with DS2500's. WOW! big step up in braking, even from cold. This is in my opinion is what should've been on a 9000 as they came out of the factory, its now fun to brake hard again and again. I'm now running DS3000's, it actually hurts your face braking hard from high speeds as you put creases in the road and stop time, dead!

So, budget brakes recommendation would be standard discs with DS2500 pads (use loads of copper slip), braided hoses and dot5.1 fluid. Oh and have a blast bedding in the pads, those that know will understand why I enjoy doing this :twisted:
