I have the full S3 setup on my car and I fancy doing a trackday sometime next year. I am wondering if anyone has first hand experience of how these hold up on track?
I will possibly be looking at changing the discs to TTS ones in the future and maybe a pad upgrade at the same time. Just wanted to know peoples' thoughts.
:happy2:
-
mine have held up fine @ Oulton Park and @Blyton Park
I now have upgraded to TTS discs (nice weight saving) and DS2500 pads which should be even better.
Good quality brake fluid and check how much pad you have left.
Warm them up, gradually increase your effort, and remember to do cool down laps and leave the handbrake off once parked up.
depends also on the track you want to try out?
-
Have you had chance to try out the TTS discs yet John? Thanks for the advice. Will probably be Donington as it's only 15 mins from me.
-
due to normal wear , I swapped to new pads and TTS 340mm cross drilled discs (my R32 345mm ones were too)
I see no reason why you would fit 345mm discs now other than they are potentially cheaper.
for the TTS disc = Smaller disc = no lip, and they weigh less = win/win
on the road feel same as before to be honest, nice progressive pedal with good stopping power, not tried on track yet.
I have cross drilled as i like them, but performance wise theres little, if any difference from solid face (vented) discs
J Hook style slots some on here have too.
-
John_O how are these new brakes on the Quarter mile? have you tried them yet. I know last time on the quarter mile you couldnt get enough speed up to actual have to engage the brakes. :laugh: :grin:
-
at least I can reach the wheel without having to buy a smaller car :booty:
-
I did Castle Combe and my S3/R32 brakes were superb
-
I did Donington on a hot summerday in conjunction with GTI Inters a couple of years back, 5 laps no more, then you will deffo have serious brake fade.
But it depends as stated above on the track and time of season. They are adequate on the Ring for example. :happy2:
-
Had S3 brakes all around and they were ok but I used Carbotech pads all around /Tarox discs upfront which are way better than DS2500 or other like it (these are a no go for hard track use). Other good options come from Pagid RS series, Carbone Lorraine, Endless...With this setup I was perfectly fine at Nurburgring and had some brake fade towards the end of the session at Hungaroring but nothing serious !
-
Nurburg 3 laps (DS2500 pads) and super blue blue. No brake fade. Lydden hill also which everyone knows its a short track with lots of braking and again no brake fade and stopped well.
-
It also depends on how hard you're on the brakes but Nurburgring isn't that hard on brakes. You basically have to keep high speeds through corners and you have plenty of cooling time on long straights. DS2500 is known to be a mediocre pad and I've destroyed 2 sets pretty fast while also having brake judder due to deposits. Never happened with Carbotech Or Pagid on the same car & brakes + much harder driving !
-
Thanks for your views so far. Tbh I have never done a trackday in a car but have on a bike. My local circuit is Donington so will be there and in the usual 15-20min session format. I have no idea if I will be a heavy breaker or not but I know of 2 big stops at Donington. Just for info current setup is OEM discs and pads.
-
Don't go with OEM pads, they have low temperature rating and will get toasted pretty fast even under moderate braking. Can you say what's the biggest speed difference between the top speed on the straight and corner entry speed on that track ? On Hungaroring for example I brake from about 200kmh to about 65kmh !
-
I'm not sure what the speeds will be yet. Like I say, I haven't been on track with it yet but I imagine the two big stops will be similar to those you have done, 120mph - 40mph ish. It depends how big my balls are on the day. Something I am yet to find out :signLOL:
-
Donington is a cracking circuit just let down by access at times,I will have to take the Edition there :driver:

It sure is. And has the benefit of only being 15mins from me. Shall I let you know when I'm looking at booking one? Trying to get a few down off here. TFSIMike and the likes.

John, could share some details? I didn't know TTS rotors fit. I thought they have different offset.
What about weight exactly?

I wouldn't mind tagging along as I've never done a trackday in my own car before and is something I want to do this year.

I didnt know either until DaveB the brake guru mentioned it.
340mm instead of 345mm , direct replacement
They are just over 1kg lighter than 345mm discs which is a great given that r32/s3 setup is already a little 'hefty'
-
THX !! :happy2:

Do you have any photos of the parts fitted? :happy2:
-
As is usual for the TT they get the good stuff.....
Don't forget regardless of what it says on the side of the box regarding diameter it counts for nothing....radius is everything
The carrier keeps the pad in the same place which is where the work is done. So TTS or R32 discs braking is the same the TT disc is way lighter
I'm doing project mu pads for the R32 caliper, not cheap at £300 plus vat but you could stay out all day with them those together with the TTS discs work very well
-
Can I ask if the pads that are listed for the TTS are the same as the S3 parts? I have an S3 setup and wouldn't mind the lighter discs. My Ds2500's are quite new and barely any pad material has gone. If I didn't have to replace them that would be good.
-
Just to note that the 340mm discs get left with a 5mm unbraked area on the inside of the discs face.

Bit confused now...did you mean the 345mm has an unbraked area?
I would have imagined that the smaller disc wouldn't have this.
-
It could just be the Mintex pads that are slightly smaller. But on mine is has left a small area unswept on the edge nearest the hub

I see. I'll check with JKM (they fitted my parts) and see what the prices are like for these. Thanks for your input.
-
camskills... 100 quid for the pads
-
It seems I need to use the TTS carriers as well (8J0 615 125). Anyone have a lead on a pair of these? :popcornsoda:

[{Panto Mode On}]////
OH NO YOU DONT!!!!!!!!!!
[{Panto Mode Off}]////
-
True ^^^ ... the 340mmd discs fist under the S3/R32 existing setup just fine.
Got to say Im very impressed with the discs and m1144 pads so far :evilgrin:

Just a little pic to illustrate the unswept area on towards the centre of the disc.
-
Racing pads never fit as well as OEM Rich and in fairness some OEM pads leave an under sweep....
Theres no lip either
I know the M1144s came with a wear sensor and clips on the back but they normally don't!
That disc looks in great shape though, got to say 44 is kind on discs....
-
Indeed... wear sensor FTW! :happy2:
Still after another set of R32 calipers if you happen to come across any cheap. (i.e.... really cheap)
-
Speak to Mr AKS......paid him a late night visit last week with said items

Great illustration of whats been described, thanks.
-
Glad to hear the 1144s are working out for you Rich :happy2:
Need to pull my finger out and get my setup fitted...
-
mine after Anglesey. TTS 340mm discs. S3 setup (calipers/carriers) and DS2500 pads
also shows the inner unswept area.

I've got some Carbon Lorraine RC5+ pads arriving on Weds, and gonna put some better fluid in the ring for my current S3 setup, will report back how I get on :happy2:
