K-sport brakes 3.0 Spec B

[kleinerbastler]

In search of a brake update for my legy 3.0r, i found the k-sport brakes. The 330mm one should fit to the 17" rims in diameter, but has anyone real experience with this brakes and rims (7" wide), because of the inset of the rims?

[blacktop™]

Are you referring to the 10 pot or the 16 pot calipers?

[kleinerbastler]

I would prefer the 8pot, i tink that is enough.

[Q]

Are you referring to the 10 pot or the 16 pot calipers?

Surely not

[kleinerbastler]

The 330mm are just as 8pot available.
The 356mm need 18" rims and i totaly new rims for summer and winter (+tyres) and the brake balance will be uncomfortable, because
there ist no kit for the rear of the 3.0r.
Please give me an advice if the 330 will fit to the 18 (or 17)x7 rim with the inset of 55mm.

don't they have a template you can print out, cut and get an idea if your wheels will fit?

y not email them and ask if you need to be "brembo clearance" for the setup to clear the rims?

[kleinerbastler]

they don´t have a template....
i got no answer until today, but i will wait.....

You really are kidding arent you?

What do you need them for? Are you doing any sort of motorsport event that is tougher on brakes than targa tasmania, dutton rally?

What is your goal of the big brakes?
Stop faster?
Handle better? (if you dont understand, you shouldnt be posting here)
Look better?
Resist fade?
Perform better in wet?
Perform better in high temperature?
Correct brake bias problems?
Current brakes have X problem?

List your desired results, and I can almost guarantee they could be fixed with shock absorbers, brake pads, lines and fluid.

Unless it's looking better, in which case go for your hearts content but know that they WONT:
Make you stop better
Resist fade more
Perform better at all
Maintain a factory aligned brake bias that is safe for use with all arrangements of passanger and fuel loads. (and performs excellently).

If you want to:
Repeatedly Stop You should: Replace brake fluid with a dot 5, and put some ferodo DS2500's in. These will work when cold so are still suitable for a street car. No point having big brakes if you cant stop for a child running across the road 2km from your house as your pads are only 60degC.
Stop Faster (less metres) You should: Press harder on the pedal, and faster. Lower your tyre pressure. Get better tyres. Get the rear brakes working by getting the front shocks and springs sorted.
Look Better You should: Buy random purple anodised 50 piston calipers with shitty cross drilled, slotted, painted, 44 piece, hard anodised carbon unobtanium ebay rotors.
Repeatedly Stop Faster (less meters more often) You should think about what the current problems are. Is it diving too hard not allowing the rears to brake? Is it boiling fluid losing pedal? Are the pads gassing causing a diminishing brake feel during one stop? Are the brake rotors glazed? Are the brake seals in order causing a high pressure loss?

Having big brakes is fine for internet pictures. But if factory STI brembo brakes off any STI are good enough for the hardest on road levels of motorsport in the country, I'm sure threyre good enough for someone using a 3.0RB liberty for any sort of hard use.

For what it's worth though you're best to get in touch with someone who imports subarus, like Risinig Sun Subaru (or gotitrex, or Doug (DTrally), or Dave from BMI or any other of the heap of blokes who do so). And get a set of 02-07 STI calipers off them. Then jump on your vendor of choice, or local supercheap and buy some DBA 4000 series slotted fronts and blank rears in 5x100, the rears being the STI adaptor rotor (part DBA2657x (x if you want slotted/drilled etc, not nessesary imo)), a pair of adaptor blanks (or make some, quite easy if you're handy on cad and have access to a CNC flat mil), some braided lines (HEL stuff is ADR approved and cheap/good quality), fluid, and some DS2500 (or your pad of choice, the 2500 is quite unreal however).

All up maybe $1000 for the calipers, $1000 for the rotors, $500 for pads/fluid/lines, $300 for adaptors/dogbones. Cheaper if you want to go 2nd hand stuff like used sti pads/front rotors/brake lines.

I can guarantee you there is nothing outside of the best of grex/alcon/brembo/etc that will perform as good as these stock brakes will with the right pads and fluid.

And if you think 'bigger' rotors will help. I can safely guarantee they probably wont. Or you would be asking on corner carvers, a cams meet, etc, not aus lib club.

If you want to:
Repeatedly Stop You should: Replace brake fluid with a dot 5, and put some ferodo DS2500's in.

Did you mean to say Dot 5.1??

@Ian
nice explanation - i need the stuff only for bling bling or how i call it to brake a 340 hp legacy.
I´m from Germany and the original STi calipers don´t have a TUV certification for the Legacy - stupid, but it is.
K-Sport brakes have a certifikation, i can buy and drive them legaly.
It is fascinating for forums, i ask an detailed question and get some things like why and you are a fool as an answer - and that all wihtout any backround knowledge - i´m sad about this. My initial question is still not answered - please help me or keep still.

[blacktop™]

Try contacting a workshop called 'A&B Motorsport' in Brookvale, Sydney. Email is probably easiest for you. They are the distributors for K sport here in Sydney (maybe even Australia) and they've done some work on few libs on here so they could possibly help you out.

I don't think there's anyone on here with k sport brakes though.

[Ian]

Q yes.

OP. If you want bling bling, ksport is not the way.

Thats like some leb in a tapout shirt with a penis head haircut and bumbag telling you he's baller as because he drives a subaru (yeah dawg, rollin in it).

Suggestion, get sti brakes certified.

[kleinerbastler]

@Ian
No bling bling, just braking.
To get the sti brakes certified will cost a lot of money additional to the costs of the brake. I ask Subaru Germany for some help, i got no helpful answer. So i would buy the plug´n play (and be happy) k-sport.


@blacktop
thank you for the info

[kleinerbastler]

They don´t fit....

[janney]

They don´t fit....

but why
