TOM.... nice of U to post the photos for the good of the order....Thanks.
PartsRack carries virtually every (good) pad for the Viper, and having owned 11 of them, and put at least 25000 track miles in, I have to say this with all confidence:
THERE IS NO PERFECT PAD FOR BOTH STREET AND TRACK. Especially if you drive in wet conditions as well, as I do.
EBC is a GREAT choice for the Cruise-In Owner, who HATES dust and squeek. The Kevlar compound is kind and gentle to rotors (Unless you wear it down to the backing plate!) It does OK for AutoX and for an occasional 1-3 hot laps. Does NOT do well for 5+ lap sessions that heat rotors above 800.
I absolutely HATE OEM (Brembo) pads... after becoming delighted with BrakeMan3 compound, (and not liking 4 or 6) I had an occasion to be forced to use OE at a treck event. It was scary bad (vs BM#) in Turn One in my opinon... could not get them off fast enuf. There are several pads better (and cheaper) than OE in my opinion.
BRAKEMAN 3! PFC 01 are very good, but expensive and dont have a rear fittment.
Some guys like Porterfields.. I used to, til I tried PFC and BM3. EBC also has 3 harder semi-mettalic compounds, Red, Yellow, and Blue....the latter for track-only.
DOCUMENTATION: EBC does have GREEN documentation to show tip-in, or onset braking torque, tested with a decelerometer, to show 7% better stopping power vs OE when the pads are in the under-500 degree range...... They stop good once or twice from 160 mph (for example), but they lack the endurance to be used for longer track sessions. REDS are a mid-way pad, higher temps and torque, but still lack the BM3, PFC, (or OE) endurance for long track days.
