Once I get home today I will snap some pics.

Glad you like it! I like my kit. Everything fits and works great.

My Freaky Parts adapters combined with separately sourced Brembo (Megane 3 RS) calipers have worked great upto now.

I just wanted post. I did the 3 day Mvading the Dragon last weekend, and Freaky brake performed amazingly well. No hint of fade, nor did it thermally overload the rotor (blue color rotor syndrome). This is a very budget friendly upgrade for those who want balanced performance & aesthetics.

Which pads did you opt for? I went with the stock Brembo pads but might go with a Ferodo DS1.11 later on.

I went with the stocks pads, to gauge the stopping power. I will be going up in slightly higher initial bite. But overall for very spirited driving, the Brembo pads are perfect.

Glad you’re happy with the kit, thanks for the positive review.

In regards to torque settings, using the table below:
https://www.m3post.com/forums/attach...1&d=1671659722
The hub to adaptors are M12 socket cap lubed into Aluminium.
The caliper to adaptors are M14 socket cap lubed into Aluminium.
Threadlock should be but grade so they don’t vibrate loose but not so permanent that you need to apply heat to remove the bolts in the future.

We don’t specify a brand or colour as there’s several versions available, not all available in all regions we sell to.

Yeah I am definitely going to purchase this kit.

How much easier is it to swap pads after a track day? That alone is motivation for me to buy. I am lazy haha

Issue with kits like these that add fixed calipers with 4 or 6 pistons is that they are paired with OEM sized rotors which typically have insufficient thermal rotor mass for heavy track use. This is compared to a full brake kit that comes with larger and thicker rotors + 4/6 fixed piston calipers with much higher thermal mass capacity.

The problem with other big brake kits is that the bigger rotors and calipers do not fit behind 18" wheels.

The ones that do fit behind stock 18" wheels have the same size or slightly smaller or larger (+/- 10mm) rotors. For example, Stoptech brakes uses 355x35 rotors (stock is 360x30) with 4/6 piston calipers - nearly the same size and heat capacity as stock rotors. A lot of people run the Stoptech without issues. Freaky brakes is basically the same set up with Brembo calipers.

So if you are looking for a set up for light weight 18" wheels, the stock rotor is as large a rotor that can fit.

My f82 M4 Essex/AP cp9668/cp9449 kit with 372/365 mm-dia, 34/32 mm-thick 72 vane rotors fits under most 18” wheels. They take a beating without fading and/or soft pedal. Also my e92 M3 with PFC Z31 372/371 mm-dia, 32/30 mm-thick 47 vanerotors fit under almost all 18” wheels and also takes quite a beating with no loss in performance. I’m running BW TA5R 18” wheels, and HRE R40 and R43 18” wheels as well as stock 513M 18” wheels

As I said, its +/- 10mm of the stock rotor. 10mm of extra rotor is not going to give significantly different braking performance.

I have been tracking on the stock M3 brake calipers and rotors for the past 12 years and 50+ track days and have not had any issues. With normal 15-20min track sessions, the brakes never fade. This is even at hard braking tracks like Laguna Seca where you need to slam the brakes from 120mph to 30mph repeatedly. You just need to run aggressive pads and track brake fluid.

The larger 4 piston Brembos adds more heat capacity and much better brake pedal modulation so it takes the stock rotors to the next level without significant cost.

I’ve been tackling and driving competitively for over 35 years.

Even though they don’t have 405 mm diameter rotors, the AP and PFC rotors have considerably more thermal capacity due to thicker disc faces, increased rotor diameter and high vane count to keep rotors cool a rotor cool by increased pumping ait thru the rotor. The stock F8x or e9x can’t compete even though rotor size is +/-10 mm diameter

I think you and I have the same amount of track experience. I've been doing track days for about 30 years now and autocross competition for 35 years.

I'm no expert in rotor design, but the stock floating rotor is pretty good for a stock rotor. In terms of cost, it is significantly cheaper than any aftermarket rotor. Throw in FCP Euro's lifetime warranty, I've saved myself thousands of dollars in rotors over the years.

You have to remember that this caliper upgrade is a cost effective way to increase the performance of the stock brakes. This upgrade is less than $1000. If someone wants to sell me a new AP big brake kit for less than $1000, you bet I'd buy it!

I wasn’t trying to imply this upgrade is not worthwhile and IMO the weak link
is the use of stock rotors which limits overall performance. The cast “floating pin” on the e9x blocks most of the rotor vane openings. F8x rotor design has maximized flow into the rotor vanes so it’s definitely an improvement over the e9x rotor

I'm sure the stock rotors can be upgraded with upgraded rotors from Girodisc, Performance Friction or others. It would definitely benefit brake fade. Or go with a whole F80 front set up. All those options cost more.

are there known Project MU pad fits this set? I love PMU pads. but hard to tell which/if one of them will fit.

It's not super clear on their website for some reason. One answer says the pads are same as Evo 7 thru 9, another answer says these are the brembo calipers from a Renaultsport Megane 275 Cup. Perhaps they are the same?

One another page where you can buy only the brackets, they say you just need calipers from a Renaultsport Megane Mk3 275 Cup

See if PMU makes pads for a Renaultsport Megane mk3 275 Cup i guess. Seems like that is the vehicle to search for.

[Mr. C4]

The Freaky Parts adapters uses calipers and pads from the Renault Megane Mk3 RS. However they no longer seem to sell the adapters separately but only it as a kit.

Same caliper here:

https://moto-dynamic.com/brake-calip...-rs,3,184,6167


Multiple brake pad options are available for these calipers.

So they also offer a caliper bracket that allows the Brembo caliper to align with F8x 380 mm F brake rotor? The F8x F caliper floating pin design is far superior to the E9x rotor design. Brembo + F8x F (and R if available) rotor is definitely an improvement in track braking performance.

Freaky brakes does not offer this. The rotor for the f80 is much larger than the e90 (380 vs 360). If you fit this caliper to it, the brake pad won’t sweep the whole rotor. It also won’t clear 18” stock wheels as this does.

If you’re looking to install F80 brakes, the whole front set up bolts on… you just need the f80 front spindles. Then the f80 rotors and calipers fit. Of course a f80 brake conversion will cost more than just replacing calipers.

Thanks. I have a PFC F and R brake kit on my car. Just curious about F8x options on the e9x. I’m aware of the F8x spindle and blue brake swap. Surprised 18” won’t clear Brembo calipers because 18” clear stock blue brakes and aftermarket brake kits. I’m running the Essex/AP Racing CP9668/9449 setup on my f82 with 18” wheels.

The problem is specific to certain wheels and certain calipers. 380 rotor with the f80 caliper combo is designed to fit the f80 18” m3 wheels. Completely different caliper design, pad shapes and mounting points than these Brembos.

The Megane RS calipers these use are designed to work with the 355 rotor on that car and so they fit good on a 360 behind 18” wheels. It isn’t designed to work with a 380 rotor.

I’m not a fan of adapting calipers from other cars as it changes a lot of things such as brake bias, wheel clearance etc. A brake kit designed for a car is usually always better. I.e. even though they use the same calipers on every application, Stoptech uses different brake piston sizes on every application to match the stock system. But this budget option works good and has no drawbacks. I am surprised it works so well.
