I installed one on mine with their TB. I had to shave a little of my factory pedal assy for smooth actuation. Other than that, I have about 1500 miles on the setup and she's solid. Their customer service has called me back on a Sunday for what it's worth.
How is the Malwood working now? The one I got that mounts on the firewall was a PITA to install and very difficult to adjust the linkage. We obviously got something wrong and it failed at about 4,000 miles. We are considering getting the Malwood if it will work with the installed throw out. If not probably do the MDL mechanical which, alas, means pulling the transmission. Argh.
It is an absolute pain in the $ss to install with the pedal box in the car. It was designed to be installed on the workbench from what I can tell. I have swapped from the American powertrain assembly after the second master cylinder failure. It is in the car but I have not driven it yet as I am doing some other mods that have taken more time than I care to think about. But it is a very good quality part.
How are you guys routing the hydraulic lines for the malwood kit?
I'm getting ready to order the moderndriveline package. They are currently defaulting to the malwood clutch master cylinder. And your choice of a hydraulic throwout bearing or the traditional fork with an external slave cylinder pushing the fork back. I am leaning towards the second option, the external slave cylinder, just for the ease of adjustments and repairs down the road.
So I will somehow need to get the hydraulic line from the driver's floorboard out and then around to the driver's side of the transmission.
The two obvious choices I see are either straight through the firewall and then snake around to the side of the transmission, or poking the line right through the transmission tunnel where it will come out closer to the transmission.
Also, how are you mounting the fluid reservoir? Does the malwood kit take care of that or do you need to get creative and find your own place for it?
Sorry I can't help with a lot of that as I'm running a Wilwood on the other side of the firewall. FWIW - It does seem like going out the firewall would be pretty straight forward and tidy.
I'm not sure if there's a disadvantage to the way it works, but I'd personally prefer to have an external slave for serviceability as you mentioned. I've had to pull my tranny twice to service mine (Hydramax) within a few hundred miles after it was installed. It's been great since, but sure would have been nice to be able to just slide under there and fix this issue in an afternoon.
