does anyone have in their notes, the diameter of the stock 121" viper drivers? i don't feel like taking out the suspension, etc, to find out the size. can anyone tell me? thanks.
A search should find several posts from last fall about this, I was one of the posters myself.
I don't recall the actual without looking myself, but 9 teeth times 2.52" equals 22.68" divided by pi (3.14) ends up about 7.21" which is very close.
I have some on the shelf I can measure too if you want to double check.

ding, if you don't mind measuring up one on the shelf to be 100% certain, that would be great. i tried searching, but only found topics on people asking about going to 8t extroverts. couldn't find anything on actual diameter specs.

a have a set of stock 9tooth drivers off my 2000 srx wich i always thought were the same. They measure just 7" but may be wore a little, probably had 5000 miles on them when they were removed for smaller ones to acommodate for tall track. Not sure how much or how fast they wear down. hope it helps
