No, I have an 87 A4 car as you know already.
But I have heard of "QUICK TIME PERFOMANCE".
I believe from the Roundy-round ashphalt and small dirt track racing circles.
Street Stock, Open Wheel Modified, Super Late Model, and The bad Winged Warrior Sprint Cars pushing around or over 900HP SBC normally aspirated.
I believe "Quick Time performance" has made a crossover to Drag racing from you links.
I also believe you can take 100% FAITH IN THEIR PRODUCTS.
I haven't ever heard of a Roundy Round Racer having a clutch and flywheel explode and cutting off their feet, getting be-headed, or of course killed.
Has happened hundreds of times for you younger guys not familiar with stories of an exploding clutch and flywheel.
It has happened to me.
Its Very scary.

It's nice that a scatter shield is offered, might make it easier to run a traditional clutch setup.

Wondering about the bolt pattern also...Using an LT1 T56 on a Gen 1 sbc only the top bolt wasnt used if I remember right. The McCleod scattershield makes it all work right...and safe. Nice piece of mind to have. The QTP are pretty light I hear. Mine (McCleod) weighed in at a hefty 38 lbs.

May be heavy, but it will save your feet and possibly your life sometime.
I use a McCleod billet steel flywheel and Bellhousing on my 70 TA.
Old school but you can count on its proven safety.

Some say that with a billet steel flywheel theres not much to worry about unlike the old cast iron ones that used to go easy but if a failure occurs, even if a clutch went you only get one shot at walking away dont like those odds. Its money you dont want to spend but are foolish not to if youre leaning on the car.
Theres a lot of weight spinning on the end of that crank and if it goes its like a hand grenade went off in the car, scary. That floorboard might as well be paper mache

Billet steel flywheel and your ok.
They think No worries.
But almost all use a Triple disc clutch too.
About 5 inch diameter Clutch Hat or pressure plate.
Centrifugal forces are less, less rotating inertia or flywheel affect because the Mass is more localized to the center.
But I have seen those Roundy Round guys blow clutches too.
They are turning 8K steady to sometimes 9K with their stroker gasoline powered Super late model dirt track cars. At my home town area track.
I watch every Saturday night there during racing season.
I help a local street stock guy win races or we try.
He has anger management issues sometimes driving.
Demolition Derby going on many nights.
Guys cant get around 2 laps without having to take each other out.
The McCleod billet Steel or aluminum flywheel may be safe, but what about the clutch disc and pressure plate hat?
Most pressure plate rings or the mating surface is cast iron yet. Unless you buy a SPEC Billet Clutch. Not cheap as you know also.
You are a Veteran mechanic and racer too.
I know you have seen many bad accidents in your time also.
Sad factor is, most could have been avoided if people think about safety too.
When you die, you are gone forever.

Also wish to add,
There are only a few aluminum alloys that maintain high tensile strength under racing load and racing engine heat.
Cheap aluminum will lose tensile strength under high heat and high working loads.
Premium Billet steels, certain stainless steels, and 6AL4V titanium alloys maintain strength far beyond common aluminum cheap china made parts.
Flywheels and clutches included.

Has anyone installed one yet?
I called and left a message today asking about them. I'm tired of the blanket...and I need a scattershield bellhousing in my class for racing.
Curious how the clutch engagement was done...since it appears they have no place for the hydraulic slave to mount on it, I'm assuming you'd have to convert to a hydraulic collar to engage the clutch.

They called me back today. Everything should work just fine, but as expected the unit isn't compatible as is with the stock ZF hydraulic throwout system.
The SFI shield is 5.775" in height, and they said with some ZF's you might need to used a 1/4" spacer? Maybe for the ZR1 units since the input shafts are different?
Anyway, it sounds like a good fit but I don't have the time right now to jack around with changing out the clutch hydraulics (which I JUST replaced a month or so ago). When I get back into racing hard and build the new car, I'll be ordering one of those up for sure.
They said you could add a bracket (built by yourself) to hold the slave, or go with a input shaft collar (which is what I'll probably do).
