Oscar is looking great Mark!

 

I'll cover both bases, since I'm not sure which marks are confusing.

The marks on the differential ring gear bolts are to verify the completion of each stage and keep track of the sequence. It is easy to forget which bolt was secured last and which is next. The first mark verifies the bolt has been torqued to 30ft-lb, after all bolts have received their first torque stage and mark, remove one bolt, apply threadlocker, torque to 65 ft-lb, apply second mark. Now you know at a glance that bolt has been torqued to the final value and from there you know which bolt is next. It is a quality control measure.

The flywheel bolts are single use, with two torque value specs, and a torque angle specification. On the flywheel, after the bolts have been tightened to the second torque stage, a 90 degree torque angle is required. Rather than use a torque angle metering device, trace the start and stop locations that will constitute a 90 degree angle, the mark on the bolt is a corresponding reference point. You can also eyeball a ratchet or breaker bar arm, but when doing this on stands, you are usually in an awkward position and at disadvantage leverage wise. This way you can adjust leverage without loosing reference.

Different bolts, different reasons for the marks.

 

Very good tips, Keith. u rok

 

what's the scoop on the seats? euro spec? or something custom? They look great

 

very cool. I dig installs that appear to be OEM even if they're not. It's my M.O. too

 

Mark, saw the pictures and know that you kissed a wall at the track, but never heard the details. Can you share what happened?

Also, I'm imagining it went something like this: [ame=http://www.youtube.com/watch?v=gQLM-K9TwWM]YouTube - In-car footage of Audi R8 Wreck at VIR[/ame]

There's a nasty little dip after the first ess that'll spin you around if you turn in too early. But the good news is that Mark is okay, and when life gave him lemons, he made GT3 oranges. =)

 

Got ya. Thanks BT.

I almost puke every time I see that video.

It's looking awesome, Mark.

 

I caught this last night during my blue-moonthly visit to NAM. That looks really great! Love the color.

 

Didn't know if you have seen this one over in the UK (MiniTorque - gazkart)

The Orange One!!

Awesome orange R53.
