As you've read, I have to redo the rear of my 99 986,,,, 80 k miles.
New track arm , new link and lower CA,
While its laid up figureed might as well get the OEM suspension replaced
Here are my choices
M030 euro susp
D2 coil over
Ksport CPO-02KP
All are within $300 of each other
I do 9k miles yr with 5 track days, was going to get a set of r compound tires this yr
