Grrrrrr... Don't say the T word. Just had to replace a pair of fronts and get the tracking done due to the thoughtless and stupid placement of pillow speed bumps. Whenever possible, I go over a pair or at least avoid straddling them but due to the placement and parking, sometimes I have to straddle them and that knocks out the inner shoulders. Wouldn't mind on my old car but the current one costs about £250 per corner to reboot.
Oh and no, not a gauge of any sort.
ETA I was sure I'd posted a reply to the t### gauge but it didn't show when I clicked on the thread!
