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...
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:
