Damn Euro, beat me to my edit!
Chatter is dependent on the flywheel or the addition of a lighter flywheel. The R series shouldn’t be any different in that regard. Most people notice nothing…I’ve driven a few JHM LWFW S4s and I didn’t notice chatter. It’s probably something that people only notice at a stoplight, windows down, next to something that sound will reflect off of like a road barrier. Other than that it’s just something people like to freak out about and worry about…lol
Got it, thanks for the lesson there!
So what I understand is that the clamping force is going to be stiffer than the clamping force of my stock pressure plate stage 4 now, weather it’s 1R, 3R or 5R correct?
If that is correct, what is the “feeling” that is different from 1R, 3R and 5R that JHM describes on the site?
“We recommend our Stage 1 R Performance Organic Clutch Disc to those looking to get the best compromise between daily drivability and torque holding capacity. Our Stage 3 R disc offers the ultimate combination of daily drivability, torque holding capacity, and durability for back to back to back pulls. Our Stage 5 R Clutch Disc is the ULTIMATE clutch disc for your B7-RS4. The Stage 5 R is a 6-puck clutch disc featuring our proprietary performance ceramic material making it the most aggressive clutch solution that we offer to date.”
Does the 5R feel more “on/off” compared to the 1R? Is that the difference in drivability?
Yea mine only chatters when in neutral with clutch depressed. Not a big deal.
Yes clamping force will definitely be more than your current setup.
“Feeling” would be engagement
Honestly 1R and 3R probably feel very similar, but the pro of the 3R is the increased holding capacity of the material. (Important for guys with a current power adder or looking to add one)
I have heard a few 5R owners describe it as more of an ON/OFF, maybe one will chime in here.
Here is Mistro’s thread

Makes total sense now thanks.
I would prefer to not have the on/off engagement and instead have something like the 3R as you describe. Is the 3R superior to the Stage 4 as far as holding supercharged power?
I haven’t seen that thread yet! Thanks!
mistros clutch to me felt the same as stock engagement, the only noticeable difference was the harder pedal. I didn’tdrive it very far or do any launches or anything but it felt totally streetable and he loves it.
he leaves hard at the track too.
I may have tried the 3R for the better pedal feel but even the guys at twins automotive who initially got me looking to jhm for performance said the way I drive I should get the 5R. and with the addition of the supercharger it just made sense.
by the way that was quite the epic blow out on that clutch lol. mine just slips into a smoke show when it gets hot, we’ll see what it looks like when it comes out.
whats your opinion on the trio or anyone elses that have it?
heres the jhm install instructions, maybe throw this link right at the top of the actual diy thread.

I went 5r and I’m getting use to the jumpy feeling on the first gear, and reverse!its not so jumpy anymore!
I don’t have it, but when I got to take the local St1 car for a spin, he had it along with a stage 4 clutch, which Btw felt completely stock to me, maybe alittle high on the pedal for engagement, but that’s beside the point, the shifter was amazing! I didn’t really bang through the gears, but he had it aligned pretty much perfectly completely changed the feel of the car, I loved it! Will definitely be a must have addition for when I order the clutch.
I have had the 5R for less than a week now and I’m pretty much used to it already. Under normal circumstances I don’t even realize the difference but the other day, for example, I got caught on a very steep hill in bumper to bumper traffic. Needless to say it got pretty sticky and I tried to wait as long as possible before moving forward but other than that I think it’s very similar to stock. You get a little chatter when your under 1,500 RPMs but again it’s pretty easy to get used to.
I really really wish I would have done the clutch earlier this year. for one I wouldn’t have to go through hell breaking it in dying to see what the charger can do and I really think I could have shaved at least a tenth off my quarter mile time while still N/A.
im just as excited to feel the clutch as I am to feel the power. I think im just all around excited right now lol.
Well your car is basically my car + a tune right?
I went 12.51@110.5
The tune could certainly have out you in the 12.3 or 12.4 range. Clutch and flywheel would push it towards the bottom of that range. I wouldn’t have been surprised to see you go low 12.3 @ 112.5 on a nice sunny low da day with that. Maybe 12.35@111.75 without the clutch .
I got the mph but I didn’t get the ET. oh well, I still had fun.
what was your best MPH
112.12 when we were at tmp.
Pm me that slip… I wanna see what went wrong
