35% is darkest I've gone. Not too bad but is noticeable so stronger chance of being noticed by 5-0 if they ticket for that in your area. 50% they usually don't notice but makes a very nice difference for the driver. I'd highly recommend 50%. That's what I have on my burb now.
Will you share a pic of the 50% front?

Removed the broken AC compressor clutch today. The rubber part of the clutch must have separated last time I drove it (making horrible squeaking noises), then it melted due to the pulley still rotating and not driving the compressor anymore and while this happened the clutch gap went to zero and it burned the friction surface too. The whole clutch is toast, but thankfully the compressor seems fine. There is no oily residue of any kind on the shaft and it spins smoothly. The Nachi bearing in the clutch was fine by the way.

This is supposed to be one piece:

Put 27 gallons of E85 in it @$3/gal

I previously had a tank of 93 octane in it and my calculated alcohol % on the DIC showed 7%. Now it's at 65%

Price went up since the last time I got it, but it's still $0.75-1.00 cheaper than 93 around here
A few weeks ago when it was 2.80 I did some math and found out that it's actually about 10 cents cheaper a mile for me to run e85 vs reg 87 with the prices out here.
