ECS Porsche 6 piston brake kit

[s42k5b]

Will the 6 piston porsche caliper setup fit inside the stock Avus rims? Please bare with me I'm a fairly new B5 owner!

[momento1]

hi mate,

i have this same kit on my S4 and no it will not fit under the stock rims. Possibly the 18inch S8 rims it might fit.

I put a set of 18inch RS4 wheels on and still required 4mm spacers to make it fit only just.

hope this helps

i have the ECS porsche kit and mine fit fine

[AddICTioN]

I think the stg3 4 piston kit will fit fine, not the stg4 6 piston.

you need 18" min for the stage 4 kit, and with a set of 18" kinesis race wheels which have provisions for monster calipers, i couldnt fit them. So i'm running 19" HREs now and they fit

[s4nicetry]

I have my ECS stage 4's currently behind some 18" flik justices and they fit perfectly w/ no spacers, but yes wheel selection will be much more limited with these monsters.

How do you like the STG4 kit? Do you track your car? Any issues with pad wear?

I was reading that ECS uses a caliper that was intended for a frount mounted location on the cayenne but for the S4 it's a trailing mounted caliper which can cause pad wear and poor performance. Something about the pots of the caliper being in the incorrect order.

Well it worked well for a while... until the BOLTs and NUTS that hold the hat to the rotor came loose on the drivers side a while ago. I'm waiting for a new set of hardware to come from ECS so that I can rebuild the rotors at our shop. I don't track the car, seems like whoever put my rotors together at ECS did a poor job or the parts were not very high quality.

They tried to say that the bolts are suposed to be loose, but not loose enough to hear the rotor rattling as you drive down the road.

Then they tried to say that the bolts were loose because I drive by myself most of the time "well do you usually drive with another person in the car?" - duhhhhhhhh again to ECS guy. I drive to work in the car and its not like i'm a 500lb man, i'm 200bls 6ft and i goto the gym regularly.

To top it all off, they said that if we put installed new hardware for the rotors then they wouldnt warranty the rotors. Well they are already not functioning properly and they wont warranty them now, so that is completely irrelevant anyway - duhhhhhhhhhhhhhh to ECS guy.

So in conclusion, the kit was pretty good, aside from the rotor hats coming loose and rattling, i'm still waiting for the hardware for the rotors. 3 weeks later, ECS tuning, is probably not be the best option, the customer service seems to be not what most people would expect. If I could do it all over again, i'd splurge and get the Alcon setup from stasis.


Hows that for an honest opinion?

[BastardS4]

6piston kit WILL NOT fit my 18" enkei RPF1s

dammit all.

[Luca12]

iv herd that the rotors rings are crappy is it true?

I heard that BK makes good hamburgers compared to McDs, but wendys is better than those 2, and the spicy chicken is where its at.

I have had no problems with the brakes other than the hardware loosening a bit, and apparently my order has shipped from ECS today.

[Jesse S.]

Should check out Alcons

-- Bigger BBK doesn't = better... 6 piston < 4 piston

Could a BBS 18" wheel fit what would be the minimum offset required?

[VOoDooGTX]

theres alot of cases where people put larger brakes in and end up making the car have less braking ability mainly because they dont upgrade the WHOLE braking system as a whole. The bigger brakes require more pressure to stop them and a stock system is built for stock brakes. upgrade one gota upgrade the other.

[sCeRaXn]

I honestly dont see why anyone would need those huge brakes, unless looks were their main goal. The stock brake bias is too forward heavy for me. It makes it impossible to trail brake in attempt to stop understeer with the stock brakes, i cant imagine how bad it would be with those huge 6 pots. I honestly think that a good set of blanks/slotted rotors up front with a nice set of pads, and larger rear rotors and udgraded pads would do wonders for the braking on this car...even with stock relocated rear caliper(if this is even possible).

They do look good in some cases, but id rather spend that money elsewhere and get better performance. Besides, i find it hilarious when people have ginormous 18" rotors and 20 pot calipers on the front and stock brakes on the rear that are barely bigger than the hub lol.

Contact Tirerack or BBS, you will have to get a template of the caliper from the ECS Stage 4 BBK and send it to the diff. tire companies so they can print out the template, fit it inside the particular wheel you are looking at and see if you have enough clearance or not.

But I know that CH's, RS-GT II and a couple of the $500+ per tire BBS wheels SHOULD clear the 6 pot caliper

-- Bigger BBK doesn't = better... 6 piston < 4 piston

exactly, the more pistons you have, the easier it is for the driver to modulate the pedal (threshold braking) it won't help you stop any better. the benefit of the BBK comes from increased mechanical advantage of a bigger rotor and less brake fade because of more surface area.

EBD should make up the the change in brake bias, but the S4's brake system isn't that advanced so it will return to the stock brake bias after it re-learns itself, it does not change according to the drivers style like some other cars do.


side note:
I agree with the rear brakes being ridiculously small, i plan on getting S8 rotors and brake caliper spacer kit when its time to replace my rear rotors, i think its $35 for the spacer brackets and $75 for longer rear hoses.

what offset would that be on the RS GTII's

[WMi_S4]

what offset would that be on the RS GTII's

Duno, tirerack has it on their website, I'm assuming 35mm??

[sti4now]

Can anyone clarify this^ Thanks

[S4-ORCE]

Do these fit behind 18x8 ET 35 Enkei RPM2s?

[Das General]

Anyone have any thoughts about the master cylinder being able to take advantage of such a big brake kit. I don't think you would see any benefits.

[AudiSportB5S4]

i know they fit behind OZ Superduperleggeras 18x8 ET35...I'm getting them, eventually.

[s42k5b]

X2^

[sti4now]

so 35mm is the key number offset

[Das General]

Not entirely. The design of the wheel, being the spokes, are really what matter. Offset is a help.

[sti4now]

BBS GTII's lets say

[JDM EJ1 95]

BBS GTII's lets say

you cant just guess or say for sure looking at offset/wheel type.. there are too many variables... like others have stated. spoke design and wheel overall designe play a huge role in it as well as the actual specs of the wheel.


theonly real definitave answer is.

YOU HAVE TO TRY OUT THE COMBO TO BE FOR CERTAIN.

[WMi_S4]

Dude, no1 is going to know what wheel(s) will fit over that kit unless they are personally running it, and it seems not many on here are.

So, my best offer is to: instead of waiting for an answer on here, decide on several different models/designs for your wheels, get a template of the caliper from ECS and send a copy of the template to the manufacture of the wheel so they can verify it will clear the caliper......I would hate to see you spend 2-3K on wheels thinking they will clear and they end up not even coming close.....better safe than sorry

Not exactly true because in many applications you will be able to know it will not work due to certain variables. For example, rotor size would dictate the size wheel needed to clear.

In this instance, ECS actually states on the website that an 18" or larger wheel is necessary, which I presume is because the rotor itself is almost 14" in diameter (352mm), and it makes sense given the length of the 6pot caliper. So...the stock Avus wheel won't work because it is 17".

Yes, yes, I didn't clarify that. W/ all 6 pot calipers, Brembo, Alcon, Stoptech, you will need ATLEAST an 18" wheel. But in many cases, as you have stated, the caliper is simply too deep for a certain 18" wheel, so then spoke design and other aspects must be considered
