The AP Racing big brake kit?

[steve b]

Think it is just a case of recalibrating my foot, you just need so little pressure for the same braking force  :-) :-) :-)

[steve b]

Did 140 miles on track today in the  spiss piss spiss ing rain, initially thought all wrong to much front bias, however after foot recalibration even in the wet my stopping distances were considerably shorter, biggest issue was shedding too much speed before the corner.  Very little pressure is now required on the pedal, on standard callipers and Carbotechs I would push the pedal as hard as I could on track, now it's so, so little required you have to be much more measured and controlled as slightly to hard and it locks up.  I think a rear upgrade to 2 pots will  add a bit more balance so less likely to lock the fronts getting the rears doing some more work.

Anyway certainly an improvement if what you want is shorter stoping distances, also I did one 35minute session straight pushing hard as I could the whole time, brake felt same on the last lap as the 1st  :-) :-) :-)

Overall very happy, except for the seriously loud ear aching squeeking they do when cold at town centre speeds, embarrassing loud, comparable to when you get a stone stuck between disc and pad.

Looks a good kit, and the prices are sensible too. That the AP pad shape is supported by many manufactures opens up many options, but what about the rotor? Is a replacement rotor easily sourced if Ksport stopped producing them?

Does anyone happen to know if the OEM 15" 5 spokes clear the caliper?

[steve b]

I asked that question when ordering and they assured me they would always be supported, Ksport going bust would be the only issue.  If worst occurred a spacer on the calliper (easy as radial mount) and a slightly bigger AP disc could probably be used.

I don't think they'd fit under standard wheels.  Ksport will email you a template to check, I think the spokes would hit.

[alackofspeed]

Thanks for the reply. I thought it a long shot they would fit, and sadly the template has confirmed the spokes will clash with the caliper.

I think if its smaller diameter rotors, possible to fit (not 100 sure) but like mine, it may not be possible to fit even in 16" wheels.

Not sure of some of the rotor (brands). mine is a brembo GT kit (Gran Turismo) that was originally an option from brembo (305mm but discontinued). also the brembo GT rotors are ridiculously expensive. my option was to order customed rotors when the time comes for replacement. You need a proper shop who does that (specs & diameter size)

 

I think big brakes are excellent for those who do track. Could be overkill for those not indulging into serious drives. Good brake pads should be ok
but i would disagree that big brakes are just bling for the spyder. I certainly find they are great, a slightly shorter distance for stopping is certainty. agree with the comment that its also found in the lotus elise. (4 pot ap racing as standard)

Bit of an update - brilliant.  Now my foots been recalibrated I don't have to think about braking, I just always have total confidence that they will haul me up lap after lap with no difference in feel.  For road yes pointless, but for track you are missing out big time running standard brakes even if you have Carbotech or other high end pads, no more standing on the pedal trying to mash it through the floor to stop, makes heel and toe much easier again don't even need to think about it makes braking distances drop to Elise / Caterham distances.  Not sure I'm bothered about a rear upgrade any more but no doubt will eventually  :-) :-) :-) . Oh other benefit is pad life, my Pagid RS4-2' still have loads of life left in them  :-) :-) :-)

Will these fit under standard 15's Steve?

alackofspeed answered that one earlier, doesn't look like it - fit under my 15" OZ fine though.

[mr-ed_smt]

Cheers Steve - clearly not read it as well as I thought! Good excuse for a new set of wheels then...

Sexy looking brakes!

Bit of a thread revival here but has anyone looked into freakyparts.co.uk, he sells will wood 4pot brake kits with 304mm discs for £540.

A kit for the roadster?

That's a good price.

[tomaky]

Ohhh

[Anonymous]

Pretty good. Interested for that price. I need to spend £300 odd on disks and pads so it's not much more

[MilesH]

Would be interested to know if you need to run 16's to make it fit?

I was thinking about wheel size along with how to justify the expense when standard brakes are plenty good enough.

[tomaky]

They can always be better  s;) s;)  hehe

[Sadlebag]

Need to speak to him but I think just having the calipers on standard discs will be a good enough upgrade. Calipers with the brackets are £420 I think.

[Anonymous]

Just enquired about stock levels, might have to buy a set now. Been after big brakes for a while.

[Anonymous]

I would say the disks are worth the extra though

[Sadlebag]

We could see about a group buy, think he's done them before!

[Anonymous]

I would be interested in a group buy if you want to inquire, just looking at options that suit what I want. I have been looking at ap as well, and until this came up I was about set to buy.
