Hi everyone! So has anybody here ever sent in a 79-86 speedo to get converted and refaced to read 170 MPH from Brother's Performance? I would just like to know if this is a decent thing to do. Do they do a good job? Does the speedo work properly? And finally how much is the whole operation? thanks everyone

just my .02 man, but i would spend my money on something else.......i am sure brothers does a great job, but you will never really need a 170mph speedo........just my opinion man, trying to help ya save some money, but you can buy a nice car part or stereo or something........and just get some white face gauge covers and stick em on yourself..........hotwheels of turborides

There is no way you'll be accurately reading anything that high. Remember, the original gauge was only fairly accurate at reading speeds under 120 mph, and you wanna put another 50 mph in the same gauge space? Accuracy is out the window....even if you could go near that fast. To maintain accuracy at any speed, this gauge would have to have a diameter 150% larger than your stocker gauge.

I replaced an 85 mph gauge with a 140 mph gauge on my Fiat Spider last fall. I did so because I was routinely cruising above 85 mph. Also the stock gauge quit working, and a new old stock 140 mph gauge was cheaper than rebuilding my original. I now find that low speed (city driving) accuracy is less than +/- 5 mph....intolerably inaccurate. And, the speedo jumps like a kid on a motel mattress at speeds less than third gear.
Look into rebuilding the stocker gauge if it is defective. There are numerous shops throughout the country that specialize in this, anologe or digital...

all im lookin for is a speedo that goes over 85 MPH... I know I will never realistically go even close to 170, but I cant find a factory 140 or special service speedo. I do tend to drive i excess of the 85 limit on my stock speedo quite often, just a kind of creature comfort for me.anyway I found a 140 on mustangsunlimited.com, I already have the nice stereo sir, but thanks for the advice.

I fully understand about knowing above 85 mph (see my previous post). 170 mph is excessive, and you would not be happy. Happy hunting....would suggest 120 mph if you have a choice. Above that, you'd really not get too many chances to use the thing anyway.

I wish I hada nother choice besides the 140 mph I ended up with...but, I didn't.

170 mph is exactly double your stock speedo, so the gears are exactly half. can you squint that small?

i got it and it sucks, it's off more then my 85 mph was.
now its just another thing to get fixed.
