Knowing that the young student will be attempting to manipulate this thrill ride - a softer, gentler clutch with heavier flywheel was procured:
ACT HDSS single disc with sprung hub to allow some forgiveness on shifts (compared to twin disc with no springs):
And 11 pound flywheel to enable easier 'step off' starts (compared to nearly nothing currently with the Cusco unit):
Hopefully will begin the teardown this weekend...
Bit of brake bleeding on-going:
Calipers have held up nicely to the track miles - although I'm pretty easy on brakes...
Moving on to more fun maintenance actions...repacking axle joints along with new boots:
Old:
New:
Unsure when they were done last and last year one split on the way home from Spa...
Both rear axles complete and reinstalled. Moving on to the Ohlins spring 'upgrade'... Many buy a new set of springs for the front typically 100's and swapping with 120's. Then taking the 100's and installing in the rear - bumping both ends similiarly or so we thought. Upon disassembling a front and rear for the exchange, noticed both were 90's. So the rears will not receive any more stiffness. Hopefully, it won't lead to excess understeer. We'll see!:
120's - Note, we paid $50 import tax on these from the UK...making these very expensive springs. Can thank the BREXIT for that...US is very lucky to avoid this 30% upcharge on everything!:
Complete!
I also elected to replace the front wheel bearings - bit disappointed as the are OEM and its not like we did too many jumps or curb hops...;-)
New, shiny parts!
We'll see how stable prices are with everything going on now.... I might be doing a spring change on my 996, it's currently set up fairly stiff for track work, I think 685lbs front and 900lbs rear. I'm thinking of moving the front to the rear and getting something like 450 for the front
Doc: you are going down in stiffness and we are going up - 30%! Hope it doesn't kill the ride. We will consider going up in the rear a bit to even it out...hopefully not.
More work done this weekend - love repacking axles joints ... but they are complete!:
Notice unusual wear marks on the inside of the left front axle...the same one under hard corning we would get a clicking...hmm. Supposedly it is an internal transfer case issue...we are investigating!
Pulled the lower engine mounting frame out (north/south bar)...replaced the rear engine mount-easy enough!:
Extracted the transfer case - plan to disassemble a bit to see if we have loose diff bolts (?):
Fresh transfer case seal - since I have one:
And swapping the other bearing to keep it even up front:
Free time on a Saturday means Evo time...installed fresh front sway bar endlinks (inexpensive OEM parts!):
A new alternator as the original has a bearing squeel until warm...unsure when it is going to take a siesta (appears an Evo 9 model is a straight bolt in for a 5):
And the car seems to be missing a transmission:
It is now on the ground...not terribly difficult...but reinstall is twice has challenging...especially in crocs and solo:
The twin disk that came with the car looks no worse for wear...just a bit too serious:
Hopefully it will go back together quietly tomorrow...it will be a Sunday and in Germany that means no noise/work (I consider this fun so...we'll see if I get reported!)
Is this a clean bellhousing or what?:
Simple Green and toothbrush after 10 mins...rinsed with Brakeclean!
