Mine is awesome! AWESOME!
(so far)
I am embarrassed, saddened, and lately angry with moments of desperate sorrow because of how little I've been able to drive my Roadrunner in the last 15 months because of so MANY damned obligations.
I have had 2 different McLeod single disc clutch and pressure plate combos, BOTH with very heavy pressure, in the 2,900 pound range. I wanted very strong clamping force, but WOW, it was really hard on my old knee. The first was a Borg and Beck 3 finger design, but it failed, and McLeod actually discontinued that model due to failures (is my understanding). I went to a diaphragm style w/2,950 pounds of clamping force, and it was smoother and a little easier to use, but still pretty brutal in stop and go traffic.
One of a multitude of mostly drag racing oriented modifications I had made to my car last year was a HitMaster launch control. I had to have a hydraulic throwout bearing installed in order to use that particular launch control system, BUT I was really leaning towards getting a hydraulic clutch anyway because I figured it would be easier on my beat up achy body.
So it was a good time to look at my "forever" clutch and pressure plate. What I mean is the basic design and layout that wouldn't hasten my need of a wheelchair, walker, or cane to get around, or knee replacement surgery, (I'm exaggerating a little, but some days I really hurt bad)
AND a clutch setup that would be in the TOP TIER of performance for a street/strip car.
I discussed my setup with McLeod, the subframe connectors, Assassin traction bars, chrome moly driveshaft and solid 1350 U-joints with the factory Dana 60 out back, my current warmed over 440 6bbl, and my future Bill Mitchell aluminum block based 541 stroker I have planned, with 700 ft lbs torque as my goal. I also discussed the HitMaster launch control. They recommended the RXT dual disc clutch for me, because of the heat and friction that the 1½ second or so of intense use it would see with the launch control. The RXT uses a ceramic metallic friction material on the discs, and that can handle that kind of intense heat and friction.
I had to break it in for around 450 miles or so as recommended. NO problem during that period other than the car wanted to move forward slightly as though the clutch wasn't fully disengaged, BUT with the hydraulic throwout bearing being new to my setup, and a LOT of other additions and modifications, and lots of phone calls to various tech support folks, the shop that did all the work, and my eyeballs on it on a lift...the problem went away on its own! I guess it may have been something that had to break in? Honestly I don't know what caused that one issue nor what fixed it, but I never have had any "I wish..." or "If only..." moments with the dual disc McLeod. A few times I may get a teeny bit of chatter slipping the clutch, but that's rare and mainly from me not driving it more.
Bottom line?
Unless you need a ceramic metallic friction material, the RST from McLeod is going to be the FINEST clutch you've EVER used! Even though they are powerful performers and have a great deal of gripping force when you want to transfer power vs lose power, they are silky smooth and have an amazingly light pedal feel!!
HIGHLY RECOMMENDED!!
I missed the races!!
