...hmmm, that's interesting. Is that true? I'll look into that for sure. thanks 8)

yes it is true of my 89 325i. I used a gps to verify in between adjustments.

there is a dial on the speedometer I think its a variable resistor, you can turn it to increase or decrease the actual speed displayed.

just remember that ur speedo is off by that much and compensate.... they're not gonna pop you unless you TELL THEM YOU HAVE A BROKEN SPEEDO.

same here, Almost all of the E30's ive owned have been at least 5mph off...

I'd love it if mine was only off by 5mph. 12 is a bit much and my front bumper in primer makes me look like I sell crack!

my speedo reads about 4-5mph high + 4% because of undersized tires. kind of nice because when i am doing "70" i am actually closer to 60. no tickets yet...

same here, Almost all of the E30's ive owned have been at least 5mph off, And on the slow side.....The first one to be right on the money is my 332i....Simply because im using the E36 electronics

Mine's 9 mph off at 30 mph. My car might only have 12,000 miles on it.

After reading that, I'm still at where I was. Thanks though!
It had more to do with the odometer than the speedo.
I'm just going to buy a speedometer sensor from BAV (Part # : 62 16 8 355 008 ) and start there. I don't need to get into dickin' with the cluster at this point as the speedo seems to function just fine.:D

I'll let ya know how it works out.
Thanks!

I'll read through it and hopefully come up with a solution.

Why can't it ever be simple, haha!

Thanks for the reply's everyone, and for trying to help me out! 8)

what are the odds my wheel sensor took a shit?

it's a 3.2% difference in size. Not quite the full 12% you are seeing but it's a good chunk of it.
