Brackets for my ZR1 calipers came in........ if all goes right I will be installing them next weekend.

Just waiting on pads, banjo bolts and crush washers. I need to do a mock up tomorrow to ensure the brackets clear everything on the Belltech spindles.
So what device do you use to get your 1/4 mile and 0-60 times, and have you used that device at the track to see how accurate, or far off, it is?

Well if it was working fine before you messed with it, and now you’re having problems…. Maybe take another look at what you messed with to Cause the problem?… just a thought…..
It's really a simple device to disassemble, clean and put back together. If it is a circuitry problem within the 2 circuit boards themselves that is beyond my skills. Yes it is coincidental but I think that is all it is.

Here I marked the contacts that control up/down and express down. And just a pic of where the regulator harness plugs in. It’s those 6 big prongs.

That gold contact patch just below what looks like the Down marking looks a bit oxidized. Also, are you cleaning the mating contacts (not shown) that touch the gold patches when you hit the switch?

Take a magnifying glass and a pick and see if any of the solder joints are cracked or components are loose. Might just need to touch up the solder joints with a small soldering iron.

Poked away at some surface rust on the front fenders. Looks like I will need some splash guards after I repaint these areas. I like the way it looks now but don't want to lose this paint again. Any other ideas?

Some vinegar and a Scotchbrite pad to start with.

I'll have to take off the bumper cover to get at this better. It's the same on the other side as well.
