What range should I use for my FD?
There are some that go up to 150, 250, 300, 320, 350, and 400.
Which one would you guys use?
BTW, the guage I'm looking to get is from VDO.
Any opinions on VDO guages?

I've heard the stock gauge starts moving up from the mid-point around 250F, so get one that's a little higher than that. I can't imagine you would need anything that reads over 300F.

between those choices, 300 would be the best choice for an FD.

You can check my website to see the VDO version that I got. IMO 250 is the way to go, because once the temp gets past 250 your engine is probably fried anyway. From what I've read that temp corresponds to the top white line on the stock gauge, and the stock gauge starts to rise around 230. If you're running evans coolant you may want the 300F one but even then you should never drive with more than 250F showing.

Actually, that's not completely true. I haven't seen it myself since I wasn't in the car, but I was at the track with some FD owners. One of them had an aftermarket temp gauge that went to 250F. It had to go to the top before the stock gauge even moved from the mid-point.

And no that doesn't warp the seals at that temp however, it's always better to try and have the car run as cool as possible (without cause limp mode that is).
