Changing brake fluid out to Castrol SRF on my 997 turbo. From what I understand, this cannot be mixed with any other fluid, including what's in the clutch and ABS reservoirs. From what I'm reading above, the clutch is run with completely different fluid/reservoir, so this should be left alone?? Does the ABS still need to be flushed as well?

If so, is the only way to bleed the clutch (if necessary) and ABS through a PIWIS or Durametric or is there another way to ensure that fluid is purged during the flush?

Yikes. I forgot I made this thread. I actually had the conversion done at the end of 2010. My first impression while pulling out of the EVOMS parking lot was "my god, what have I done???? I can't drive this thing!":) Literally only took me a handful of times afterwards to get used to the heaviness. Honest truth, it doesn't bother me at all now. It's most certainly different than my DD (Subaru STI), but everytime I get in the turbo, it's just not a big deal. That being said, if I lived in Los Angeles and had to use this as a commuter car, I may have another opinion.

If you convert to the exact GT2 setup - then it removes it.

If you convert to some hybrid by a 3rd party then you will need to check with them.

Hmmm....thanks Loren. I'll have to find out if the setup is some bastardization. But I imagine if every GT2 out there has this, it must be somewhat usable or there would be a lot of pissed of GT2 owners with a very expensive vehicle that's virtually undrivable after a few shifts, no?

Give this a try, push the clutch pedal at least 30 times, with the engine NOT running, till the assistance is reduced till 0 ( pedal feel firm). This is the real pressure without assistance, i'm pretty sure you will need the assistance back ASAP, unless you have a bionic left leg.

Well...maybe I do have a bionic leg.....bionic chicken leg, more appropriately:)

I may have been mistaken if I said the power assist was completely removed from the clutch. But I suppose that is part of my question. Does this conversion diminish the power assist or remove it completely? I agree that zero assist would be intolerable just after getting out of my driveway.

Just picked up an 07 TT a few weeks ago and haven't had much seat time, but I've found the clutch to be a bit tricky. Not a lot of feel with engagement. Very close to the floor, but other than that, I just can't seem to get a good read on when it hooks up. Before I got it, I was expecting the pedal feel to be firm, but it was surprisingly very, very light. My Mini's clutch actually feels firmer.

I thought I liked the ease of the pedal, maybe still do, but a friend at EVOMS mentioned this 'upgrade' to me and it sounds intriguing. Removes the power assist and gives back more 'feeling' with clutch engagement. Only downside is it makes it much heavier and harder to depress.

Anyone done this conversion? How much firmer is the clutch? I've felt clutches without an assist and I dunno if I could deal with one on a car I actually own

Input/opinions appreciated. TIA.
