BFI - 1.8T Longitudinal Clutch & Lightweight Flywheel Kits

[Black Forest]

We are very excited to be able to bring yet another new product to market along with the help of Competition Clutch. These new Clutch and Lightweight Flywheel kits are offered in 5 different stages, to meet a variety of applications. Below we have outlined and simplified what each kit includes to give you an idea of just which kit is right for you.

LIGHTWEIGHT FLYWHEELS:
Our Ultra Lightweight Flywheels are made from investment cast 4140 steel which tips the scales at 18.4-lbs versus the stock flywheel weight of 26-lbs. These are superior in strength and far lighter than their stock counterparts, allowing you to free up more horsepower and rev faster than with your sluggish factory parts. Included in every kit.

STAGE 1 & 2:
Both full faced, steel back, brass plus sprung discs. Stage 1 includes a 1900 lb pressure plate, good for a max torque of 210 ft lbs while the Stage 2 kit includes a 2500 lb pressure plate good for 300 ft lbs. Both 1 & 2 are geared for street comfort and daily driveability. This is an ideal upgrade for a stock turbo plus bolt-ons.

STAGE 3:
Our Stage 3 kit includes a full segmented, ceramic, sprung disc, and 2500 lb pressure plate, good for a max torque of 400 ft lbs. This kit is ideal for spirited driving and would also pair well with a K04 turbo upgrade.

STAGE 4 & 5:
Our Stage 4 & 5 kits are comprised of both a 6 puck, and 4 puck copper, sprung, ceramic disc respectively. Both kits utilize our 2500 lb pressure plate. The Stage 4 kit is good for a max torque of 500 ft lbs while the Stage 5 kit is good for a max torque of 550 ft lbs. These kits are great options for a big turbo set-up.

In addition to the parts mentioned above, we also include brand new hardware, a specific clutch alignment tool, and a brand new OEM replacement release bearing.

228 or 240mm?

They are 228mm.

So if I want to do repeated 4500 launch control launches would a stage 5 be the way to go?

[diagnosticator]

Light weight flywheels are not a good choice for a daily driver car, due to the increased tendency to stall if the clutch is engaged to fast, and the additional NVH with annoying transmission gear tooth lash rattle.

It would depend on the power levels you are running. If you plan on racing like that with one of these clutches we would recommend Stage 4 or Stage 5.

Pretty cool, always good to have more options

What's the clutch pedal feel like? OEM like at all?

The clutch pedal will be a bit stiffer than stock, as it's using a stronger pressure plate.

Too bad no 240mm version...

The 228mm kit will be more than adequate for any power levels that will come out of most 1.8t applications. I've pulled this response from another thread that addresses why we went with 228mm over 240mm.

There are a number of reasons to stay with a 228mm vs a 240mm. While a 240mm flywheel would have the advantage of having a higher friction rate at any given disc material configuration. It also suffers from some setbacks. The overall mass of the clutch and flywheel would be greater, causing more inertia (which could be a positive in some situations, except when trying to lighten things, its a bit counterproductive).

We have worked with Competition Clutch to pair the friction compounds to a 2500 lb pressure plate, to give a clutch and flywheel kit that will perform as well as its 240mm equivalent (or better) at each stage of friction material (Stage 1-5). In addition to the benefit of less overall mass, and better grip (higher overall burst speed) the use of the 4140 investment cast flywheel, along with a 228mm clutch yields the best performance per dollar. While the heavier pressure plate imparts a slightly heavier pedal feel, it also gives a clamping force that will allow each disc to grab strong and hold the power for even applications that even exceed its torque rating, for years to come.

Pretty much all of the other Audi cars come with a 240mm kit and there are plenty of A4 1.8t owners making the same type of power a B5 S4 2.7t stage 3 cars can make. Are you saying a 228mm clutch would be enough for a Stage 3 S4? It would be completely crazy to think it would work. This is exactly why many of the clutch companies doing A4 1.8t kits went to a 240mm setup for A4 1.8t owners that are making way more power then the 228mm kits could handle.

The 228mm kits have their place and their limits.

Every 228mm after market clutch I have installed has failed! Failed! Failed!

I have had 5 clutchs in my 2004 B6 A4 1.8t K04 6-speed Quattro.

So far the only clutch to survive is.... my current JHM RS7 clutch setup.

Funny...the clutchs for the B7, B8, B9 are all 240mm from the factory....Hmmmmm....

I have the JHM RS4 kit too. Love it. No chatter or noises like diagnosticator mentioned. And I never stall the car, because i know how to drive a manual lol.
I wouldn't buy this BFI kit for many reasons. And who the hell makes a stage 3 clutch that can barely handle k04 power and call it stage 3? Then have a stage 5 lmao. Smh.

Have you ever tried our kit? Saying that others have failed doesn't mean that ours won't hold up to it. What other clutches have you been through and what were they rated for? When it comes down to it, we have sold plenty of these kits, and have yet to see any reviews or feedback stating that they will not hold the numbers advertised.

I don't think I've seen any K04 1.8ts getting near the 400ft-lb limit that we have on the Stage 3 clutch kits. Typically they aren't even in the 300 ft-lb range.

"Extensive use of magnesium, combined with open gearwheels, hollow shafts and a smaller clutch, reduce the weight of the transmission by 35.3 pounds compared to its predecessor, and further serve to enhance performance by giving the A4 an improved power-to-weight ratio."

According to the press release from Audi USA, the B9 is actually going back to a smaller clutch.

Fair enough!

All of our kits are manufactured by Competition Clutch, which isn't in your list of tried clutches. ;)

At least you have found something that holds! If the time comes that you ever need another one, be sure to keep us in mind.
