Soon be buying a MK5 GTI and first thing i was thinking of doing before anything else was making some slight changes to brakes as i've read through the forum that the standard breaks aren't really a good match for the cars performance where as Seat Leon's, Ibiza, R32's, S3's etc are fine as their suffice enough for the power of the vehicle their supplied on.
Would a case of changing the disk, pad and possibly brake fluid setup be the suffice enough idea to go through on the standard GTI as i won't really have enough funds to spend £1500 on a big break setup straight off but i would like a bit more confidence when breaking than what i've heard of the standard setup.
Next thing is what standard braking setup would be best for me to buy as there is a lot to choose from and i don't know whats good from bad and I'm sure you guys could throw some good suggestions up for me to have a look through and consider.
Thanks in advance.

I can't say I've noticed a problem with the brakes on my GTI at all, especially for a 200bhp hatch... more than good enough.
Large BRAKES do not improve braking automatically.
Fit new OEM discs, Ferodo DS2500 pads and ATE Superblue fluid.
Another possible option is 4pot Brembos from a Porsche 996TT , using 312mm discs.
-
Good to get another persons opinion
Would around £1500 cover a brembo brake kit as you mentioned?
Just going off peoples reviews on the standard brake setup and seeing whats out there to improve whether it can be improved with grooved/dimpled/drilled discs and some decents pads etc cause i know theres a lot of choice and it just baffles me cause i've never give the standard brake setup a thought until now.

EFA!

Same thing they're all from a Porsche.
Either way fitting fancy smanchy discs is a waste of money. Slotted might help but just to improve bite . I'm sure others will agree but normally they're the people who sell them.
Fit better pads and fluid. That is the best bang for buck.

Sorry don't know what EFA means
Thanks for your advice Jay i think i'll do as you've said until i actually need a bigger brake kit when i hopefully get a few hardware mods added
-
R32 / S3 / Cupra 345mm upgrade?
Often come up in the for sale section for around £300 - very decent bolt up upgrade :happy2:
Much prefer the APs I have now, but for the money the 345mm OEM option shouldn't be ignored.

Edited for accuracy.
I had R32 stoppers on my TDI.
My GTI pedal feels better.

Thanks gareth i'll keep an eye out :happy2:

The GTI brakes are ok for standard power as long as you have good OEM pads/discs on there and most importantly a fresh brake fluid change - they are quite strong with nice new fluid.
Once you start looking at 250bhp+ it's time for S3/Cupra/R32 brakes at the very least - but they are REALLY heavy. The 4 pot Porsche calipers are both lightweight and strong retaining a 312 disc... then onto a proper BBK.. depends how much you've got to throw at it, but in all honesty grab a fluid change and new discs/pads if required and see how you get on. :happy2: You haven't got the car yet!
-
That helps a little more so thanks for the input :happy2: Now all i have to do is find the GTI I've been searching for :smiley: :driver:
-
If your going to be adding power then upgrade your brakes instead of new pads, discs and fluid.
As mentioned, R32/S3 for valve and a very noticable improvement or 4 pot calipers such as the Porsche Brembo 986 kit (otherwise known as the NQSBBK on here) which are a LOT lighter weight option but cost around £800-£900 if your sourcing the parts for the BBK yourself or from £600 second hand on here.
Combine an BBK with some better rears such as S3 or Caddy 2k's.
Lots of threads on all the above. :happy2:
-
IMO there is really no point upgrading your breaks until you have increased the power in the car. That being said I am on a revo stage 2 and still have standard breaks and not had any issues in all honesty.
-
I have never found my standard brakes to be lacking in power, they have saved my ass many a time! :driver: My car is unmodded though, so if you uprating your power then you might need something better.
-
Thanks for all the info. I've taken it all onboard so shall wait and see what happens in the near future when i get the motor

I'm sorry, I disagree.
More pots and/or a larger caliper and/or a larger disc does not automatically give better braking. It may help improve fade but only because of thermodynamics or something like that. Larger surface area means more cooling and more ability to maintain heat.
The main problem is fade.
You can fit 18 piston calipers on a 700mm disc but you can only stop as fast as the tyres can grip. The tyres are the limiting factory ultimately.
The best bang for buck upgrade would be high performance pads and brake fluid..... and is all you NEED.

^^^^ No need to be sorry! :laugh:

Sorry Jay, but I disagree.
Without going into a mass physics debate, if your GTI (with standard 312mm front brakes) is rolling alongside say, RedRobins GTI (with 330mm AP four pots), and you both were to anchor up at any speed - he will stop first :smiley:
-
No need to be sorry. ;)
On the same tyres on the same road, all things being equal, I can't see how.
You are limited by your tyres. If your tyres can only hold 0.8g of braking you can only stop at 0.8g... even if your brakes are capable of pulling 1.2 , for example?
Correct me if that's not right.
However after 3 attempts while his would still stop i would imagine the stock brakes would be suffering with some amount of fade.. THAT'S where big brakes kick in.
-
I think we need a DaveB in here really....
although I agree with your thoughts on fading - my APs are unreal. They just feel stronger than standard or R32 brakes that were fitted before, and never ever seem to fade :happy2:
-
Braking from high speed and you'll notice the difference between setups... take 3 GTIs. One with 312mm... one with 345mm and one with 362mm 4 pot. Braking from 100MPH, and you clearly see the benefit.
-
I have VWR 6 pots fitted to mine and couldn't imagine going back to standard gti brakes.
The difference really is night and day in terms of stopping ability
When travelling at speed the VWR brakes enable you to loose speed at an amazing rate.
Everytime I drive my other halfs car I nearly fail to stop because I am so used to my brakes where you only have to touch the pedal to stop.
Best upgrade on my car in my opinion.

Did you make that up or find it on the interweb?? :signLOL:
If the tyres are the same on both cars (one with the OEM set up and one with a BBK set up) of course the car with better brakes will perform better!

Do this unless you are tracking your car or planning to go beyond stage 1. I ran standard brakes with Revo stage 1 on the road and it was fine. :happy2:

Get some of these. Expensive but an amazing product, once you've had them you'll never want to go back.

I don't make things up :P
You can only stop as fast as the tyres will allow you (ultimate braking)
Larger/better brakes will be less susceptible to fade and thus allow you to brake more reliably more of the time (eg in repeated runs) .
