Default STi Hawkeye brakes - better performance?

Hi all,

I have an 06 Hawkeye and find the brakes a little poor in terms of heavy sessions on the braking pedal.. I had another one not long ago and that handled spirited runs a bit better, with no soft pedals. Both of them had standard discs, unsure of the pads though.

I bled the brakes two nights ago, whilst that has made a difference I want to know what I can do to keep them a little cooler and firmer? I don't fancy fitting ducting from the fog lights though!

Would I see a big difference from discs alone, say godspeeds?

I'm tempted by braided lines and the GDF brake stopper but also aware this won't stop spongeyness.


Cheers for any recommendations or advice!

brake lines to start with and see where you go from there.

The pads will make the biggest difference , you can fit big discs with 6 pot calipers , and if you fit low quality pads the brakes will still be awful !

A good quality grooved disc will also help performance compared to a standard disc , but again won't really help with poor performing pads , good discs and pads should make it a lot better
Cheers Ian

Makes perfect sense, cheers for the reply Ian. If I'm after fast road use (no intention of tracking ever) do you have something you could suggest for me?

Corno. I can highly recommend giro disc discs and pads. Discs are two piece and run them
On my widetrack with braided hoses and they are amazing even after a heavy session.

Decent pads and braided lines will make the world of difference.

Where can I buy these from? Did a quick google and all it returned as an old group buy on here. They certainly look the business!

I've had newage WRX on 4 pots with a variety of disc, pads and fluid, with braided lines - awful regardless of pad compound or disc (and I tried some expensive ones), the newages are just too heavy. I replaced them with K-Sports on EBC Blue Stuff, the difference was night and day.

When I bought my current STi it had Brembos on.
I know a lot of people rate them, but I found the stopping power wanting still - it was better, and with decent pads and discs would probably be a lot better, but I swapped to them for the K-Sports I had on my old bug and am still very happy with them.

I'd be tempted to just buy a set of AP's with 330mm discs - they'll clear 17" wheels and whilst expensive, I would venture brakes and tyres are the two things you should never skimp on on a performance car

The best Brembo upgrade I've ever used is Performance Friction 2 piece floating disks together with Performance Friction pads (lots of options).

Work great from cold and will make you lick the windscreen when up to temperature, never had any fade on track days.

Currently on my 3rd set over 6 years, well worth paying the extra.

Not cheap but if you want the best out of the Brembo's they have flipping awesome stopping power!

Get the full setup with the correct PF bells, I tried the cheaper version with cheap gold coloured bells and they were made of cheese, warped within 6 months of road use.

Other than the cheap bells from another trader, I've always used Alyn at ASPerformance, brilliant service, knowledge and prices!

+1 for As performance,Alyn is a top bloke who knows his onions, and will call you back/pm you without fail if he says he will. Had something as small as a bleed nipple the other day from him and he only charged for the delivery which was a couple of quid, and as always, it was a with me next day. If only every supplier took a leaf out of his book.

Thats the problem with some companies , they have bells made thinking aluminium is just aluminium and it isn't , we use a very high grade of alloy in our bells , and in 25 years have never had a bell fail or distort .

We make bells for the PF discs , and it gives you a good cost saving over PF bells , with NO downside.

To the OP , we can offer you various options depending on your use and budget.

Normal day to day driving with some spirited driving now and again , we offer front and rear grooved discs with black painted centres and kevlar pads for £299.50

Hard road driving and trackdays we offer again grooved front and rear discs with PF Z rated pads for £375 , of with CL RC5+ pads for £450 , the CL pads are very good but can be squealy at low speed low pedal pressure driving.

As well as offering PF discs with either our own bells or PF bells , we also offer our own 2 piece discs and bells , as an example our 2 piece grooved front discs and PF Z rated pads are £425 , or with CL RC5+ pads £450.

As always all our discs come with a 12 month guarantee even if you do track days

Hope this helps

Cheers Ian

I run the Godspeed grooved 2 piece bell and disc's with AP4 pot's and Ferrodo DS2500 pads, excellent in every situation and no fade on the road after repeated hard stops. I live in an area a kin to the peak district so they get a regular work out.

Another quality to add to this set up is they last a bloddy long time too and you can get every last mm out of the pads as they don't disintegrate, 17k and still counting on this set, I actually bought a replacement set of pads a little while ago thinking they were getting a bit low, that was 4k miles ago and they're still in the box in the garage.

These are on my Blob wagon PPP.

Another vote for the pf discs but I've got the brembo sport pads fitted, wanted as much oem feel as possible (or cold bite if you prefer.)
Alyn fitted & supplied mine, as said previous, excellent service from him & excellent stopping power as well.

Thank you everyone for the replies

Looks like I'll be replacing a little sooner than I thought as I measured the discs over the weekend and they're on 29mm now !

Will be sure to contact all traders in this thread and see what my options are

I meant to ask - I've read horror stories about removing the calipers to change discs/pads.. Are the brembos really that bad? I'd rather DIY if I can or is this recommended for a shop to change?

Just thought I'd give an update.

I decided to go for Godspeed disks and pads, and some HEL braided lines from Aztec.

Rear calipers came off fine, disks were a pain with the handbrake shoes but now I know for next time
Front caliper bolts were seized (shock), managed to get the bolts out but stripping the thread in doing so. I was just relieved the bolts came out in one piece!! I ordered a heli coil kit and new bolts from Mark at import car parts and did that over the weekend. Fitted the new discs and pads and they're now bedding in

I managed to fit 3/4 of the braided lines till the last one decided to p*ss brake fluid everywhere as it wasn't crimped on..! Thank god I found this out whilst bleeding and not whilst driving. One email sent to HEL and they've apologised sincerely and within 20 mins of sending the email (on a Sunday too! ) and there is now a new line in the post for me.

Looking forward to installing the last line and bedding in the new setup, thank you everyone for your help

Awesome cheers! Surely they would be the same stopping power as my four pot Brembo's? Pretty sure discs are about the same size, 330mm?

Your Brembos are ok for the job with the correct pads for the scenarios you want.

This has happened to us as well with HEL lines which is why we don't use them anymore , we now supply Hosetechnik and have done for a number of years and find them faultless , these are made in the UK , very good kits with total piece of mind

It's not exactly confidence inspiring when you're installing them.. I honestly dread to think what would've happened on the road ! Loving the discs and pads so far Ian, thank you for your help over the phone.

I've never been able to experience AP's (yet!) so one day hopefully I can and can get a good comparison My Brembo's do get a regular bashing often so who knows what the future will bring.

Little update - have since done approx 2000 miles on new discs, pads, and braided lines. Huge difference and confidence in the brakes now! I think I'll get a brake stopper next
