Ah ok so I'd of thought the xp8s would be perfect for a type r with no abs.
Might try these next if they last longer than CL rc6s and don't squeal and kill cheap grey iron discs.

Is is not the opposite of what you are saying, as the clamping force is a result of applied force divided by area, so the hi-spec has the smallest pad area, then brembo etc.
Best thing to do to get a good balance is to fit a bias valve, which you can adjust to suit various setups and driving styles. Although your limiting factor is then the rear brakes
Hope this helps!

Its pointless having massive clamping force and then no way to dissapate the heat it generates.

The brembos with effective heat managment generate one of the best clamping forces, if you can remove the heat from the caliper they are one of the most effective brake set ups out there.

How on earth do you effectively increase the heat dissipation on them?

2 piece rotors the alloys bells act as a heat sink, better pads that operate in a higher temp range, fluid that can cope with higher temperatures etc, even brake ducts....

I wouldn't touch Hi spec with a barge pole.
Put sone good disks and pads in the brembos, I've known experienced lads with big power cars use the brembos to good effect

Might have to at this rate. Turns out there was some confusion and the Hi Specs were 5x100.

where did you get the 'clamp load' data?

THIS!And you will be good to go,the Brembo caliper is a very good unit once you set them up properly and can be used into the 500bhp+ power range without much complications once set up right as above.SJ.

Cheers lads lol. I'm just finding it hard to reconcile spending £600 on the discs and pads for the Brembos when I'm not entirely convinced by them for hard track/race use!

Bigger brakes arent going to change that? Infact discs and pads are going to be more expensive for the other styles of caliper.

Brembos are proven on big power cars, Joe and Ade (Stone Jedi) both have alot of experience of this. You arent running enough power to need big brakes...

Braking is a very important function of your car,try not to scrimp in that department especially if your using your ride on track,£600 for a decent discs/pads etc...is the norm.SJ.

Starting to seem that way, I've pointed out to mate the Brembos with correct pad and disc, but bigger is better apparently

I'm a worrier. I just have to make sure I'm 100% happy with something before I commit.

I also didn't say that spending that sort of money isn't normal, just that I want to be completely sure I'm not missing a better option because once I buy those bits then that's it, I'm committed for at least the next six months. I'm sorry if that's rubbed anyone up the wrong way.

Currently only running about 330bhp but it's a forged 2.1 so there's definite 400-500bhp plans ahead. The power is kind of irrelevant though, it's getting the big heavy beast to stop quickly and consistently during track use that I'm interested in. I haven't ruled out the Brembos at all.

Don't mind the discs and pads costing more mate, but explain to me WHY bigger brakes won't be any better? That's the bit I don't really understand.

If I stay Brembos will the two piece Godspeed discs be good enough or do I really need PF?

Ive already explained it.

The clamping force/torque is significantly less on the k sports etc compared to the brembo calipers you have.

If you have less braking torque the brakes are not as effective.

The reason why brembos fail or are not up to scratch is because they are a white alloy and suffer majorly with heat. With big cast rotors, alloy calipers etc the caliper acts as a heat soak which in turn heats the fluid and induces fade.

However with effective heat management they are better than most of the other calipers put there.

The only advantage with k sports etc is better heat disappation, so they will manage the temperature better, but you will have overall less braking torque. However you can lean on them harder for longer...

The downsides with cheap brake kits like k sports, they sucker you in with cheap initial costs, then when you need spares its almost as expensive as buying another whole kit.... they also mainly lack dust seals and some other important parts... You will find that on 8 pots etc the front on the pad wears alot faster than the rear due to the lay out of the pistons it is not possible to get full braking torque on the full face of the pad.

Cheers, but the likes of AP etc. does that also apply to them re: less clamping force than the Brembos?

You wont get APs or alcons for 600 notes though.

The difference with ap etc is spares are a 1/3rd lf the price and they have dust seals etc.

Even 6 pot aps do not give the same braking torque as the brembos. BUT, as with the k sports etc they will deal with elevated temperatures better for longer.

You either spend out for decent stuff or upgrade the brembos. For cost effectiveness I would be upgrading the brembo and maybe looking at driving style so you hit the brakes less and arent covering them etc while cornering. Progressive braking will help reduce heat as opposed to one stamp on the brakes into the corner

JGlanzaV any more advice and you will need to charge him Lol...To the OP you have been given a full explaination of how brakes that you have enquired about work with the right disc and pads set up,in all honesty their is not really much that can be added.....All the best with your final decision.SJ.

Absolutely. I'm not saying that's my limit, what I was trying to say was that I'd be able to get bits for the Brembos for about £600 but I could spend a bit more, say £800 and get used APs or some of the other options. If a set of APs with bells came up for £700/£800 I'd have those, otherwise it looks like I will actually upgrade the Brembos. Going to give it a couple of weeks to see if any come up. If not I'm thinking Godspeed two piece discs and decent pads.

All APs do not have dust seals. Only the road versions do.
