Ya man, exactly what I am looking for! This is really more of a discussion to try to keep interest going.
I have run my 85'GS since 2006
2006- only thing done was my motor was rebuilt just in time and hit breakin miles on the way there. Mild Streetport. I couldn't really feel a difference, very little power increase.- at that time damn near stock
2007- not alot done, changed tire brand to Sumitomo, I really like them, I noticed a difference right away in AutoX. Made a difference in the Dragon.
2008- Suspension Tech springs, bushings, Re-Speed strut bar, same Sumitomo tires, But got the RB intake with Holly and the full RB exhaust. That was my best set-up ever!
2009- GSL-SE Suspension Swap, Suspension Tech big fat front Sway and Rear Adjustable (Which I set for Understeer and It Is Totally Worth It!) It takes something serious to kick the ass end out of it

For the 14" rims, I went with the Sumitomos again, BUT, was in a rush, ordered the the wrong type, So I normally order the HTR Z (I or II) but somehow got the reg. HTR. My tires this year were HORRIBLE! But didnt realize till I got there. They Screamed so bad and traction was damn near non existent The combination of a seriously stiff suspension and bad tires sucks.
So for next year, all I am changing is getting the right damn tires! They have done great in the past, and looking forward to see the difference on the 14" and with the sway bars.
