such a nice front end, is the 35th bumper necessary for that lip?

I don't know for sure, actually. The lip is held in by a lip retainer which I know is specific to that lip. Whether it's specific to that bumper is another thing. I couldn't tell you.

So I drove an ST on a whim today. It was a really fun car, but man was it slow. Great torque made for a pretty responsive pick up but the drop-off at the end was sharp. It's faster than a stock GTI for sure but much much slower than stage 1.
Other than the power, the car had a great feel to it. Weighty without feeling heavy. Everything felt direct which I appreciated. The clutch was great. Very grippy, but overpowered the engine, too. Drop-shifts will cause the engine to stutter a bit.
And my god, those seats. Wow are they good. Probably bad for long trips because they really keep you in place, but that initial "momma just tucked you into bed" feeling is wonderful.

Car just passed 42000 miles, so an update is warranted. I've had the car in stock mode for about a month now so that I can keep my flywheel once I save up for HS Tuning's RSR kit. Otherwise, I consistently get slip from the initial overboost. And you know what - it's not bad. The intake and intercooler are definitely keeping things peppy and stronger than stock on its own. That said, I've developed a weird boost profile I just noticed this afternoon.

Somebody buy my wheels? plz?
Need clutch $ so bad. Been in stock mode for the past couple months as slippage has gotten worse and worse.
Edit: Also, the strange boost issues from above have disappeared. :iono: oh well

Sweet. If you don't get it installed this weekend, I'm down for next weekend as I will be doing motor mounts, manifold, waste gate, intake gasket, valve cleaning and compression test. (Just a few things Haha)

Oh I forgot about the valve cleaning. I'll need a specific bit for that job

Installed!!
From the install:
Had a lift and an engine bar. Wasn't as helpful a combination as it might seem.
Zip-tied the starter out of the way
So here we are with the transmission unbolted, trying to wiggle it out. Unfortunately we couldn't find a way to do that with the subframe on. Just wasn't enough space without hitting the downpipe, frame, subframe or clutch.
Subframe contact
Flywheel/pressure plate contact
We did eventually get the beast out of there. Notice the lack of a subframe, though. Didn't have the bolts to replace, so I used the old ones. Looks like I have a project for next weekend now, too
My tranny had some shards in there
Old TOB
New hotness
Old clutch (bottom) vs new RSR (top). Hey HS, go ahead and use this photo if you like
Old PP surface
Old plate
New plate
Flywheel condition
LOTS of dust. Cleaned it out with a blow nozzle and pressurized air.
Didn't have an alignment tool, but it was alright. Found a suitable socket to put into the disk and the inner race of the engine output shaft had a light chamfer, so pressing the socket against it aligned the disk nicely.

My impressions:
In terms of firmness, clutch uptake is much more similar to a Honda or Ford (my most recent drives of either were the S2000 and Focus ST, respectively). Seriously - if you want to take this clutch for a test drive, go drive an ST. The way the ST's clutch engages is strikingly similar to this. That is, the pedal gets very firm just as the plates engage. By the time the pressure lets up, the clutch is 100% engaged and there's a bit of extra travel (maybe 1.5 to 2") at the top that's light and a bit mushy. I might just put a stopper before that point so I don't have that extra bit of travel. It's a rewarding feeling clutch in contrast to the stock clutch. You have to work a bit harder for a shift, but the payoff is more confidence in the grab.
And this thing really grabs. It's clear that HST is achieving high torque holding with a really strong pressure plate. That's fine by me - I'd happily pair the stock disk with a much stronger pressure plate if I had the option. To bring it home for you guys, let me draw an analogy to everyday life. You're moving, carrying heavy carboard boxes. You don't have a great grip with your hands, so what do you do? Grab harder or wear gloves? The RSR is a firmer grip, whereas other clutches with foreign materials are the gloves. I'm not saying one way is better than the other, but this analogy highlights the different approaches.
It's more difficult to modulate than stock, simply because of the way the pressure plate pushes back at you. Nothing an experienced MT driver can't handle or even master better than the stock clutch. There's much much less dampening of movement. You can work this thing quickly and it will keep up with your movements. Its quick ractions are a part of the reward of using it.
I can definitely feel the clutch better than I did before. I attribute this to the strong PP and (more) fresh brake fluid. On the other hand, I don't feel the road any better through this clutch because of the DMFW dampening the toque ripple. That's alright in my book - it keeps this car just as refined in the cabin as stock. Literally no difference in NVH.
Anecdotes of driving the GTI with a stronger clutch in general: I didn't realize how many times it was slipping. Not like the RPMs taking off without agreement from the wheels, but mostly when you jam the throttle. With a good clutch, it'll hold for that first instant tip in. It'll really try and whip your neck. With the stock clutch, there must've been a tiny slippage there because it never felt so instant. I thought it was the DMFW, but I guess not since it's still in there.
