Ok, I noticed on Rotary Resurrection (http://www.rotaryresurrection.com/2n...nter_info.html << link for information, ) It says the rear auto counterweights are all 4.0 for 86+. I know same year to same year, But what is the real weight of the different year counterweight?

Another question, I'm sure it will work but need to make sure. I can run the stock fd flywheel on my s5 n/a correct? (Same weight as s5 tii)

 

the 89 rear cw has a different part number than an 88.

i beleive you should be able to run a stock FD flywheel.

 

I know the part number is on the counterweight, But I just want to know the number. I know it's not 4.0 for 86-92.
