This thread makes me want to go back to the track. I did an HPDE at VIR in my e36 M3 back in 2006. Thanks for the videos and details OP. Pretty encouraging to see how the red P3D performed with MPP comforts and upgraded pads. Do you think the master cylinder brace would help brake feel on your wife's car?
I think it would help with initial feel, but it would not prevent pad fade so you would still end up with a squishy and mushy brake pedal from boiled fluid and overheated pads.
So would you suggest the comforts for a agressively driven p3d street car that might see one or 1 track day a year ?
I would definitely suggest the Sports. FWIW, I never intended to take the Red 3 with the Comfort's to the track. It just kind of happened lol. If you are planning to go to the track though, Sports are the way to go.
Looks like you're the guy to ask this; can't seem to get feedback on it elsewhere.
Did you notice and downforce/handling differences on the front end with the UPP lip at high speeds?
It's definitely not going to be something you're really going to be able to notice. We're talking about a pretty minimal change. There is a change, but can you as the driver in a 4,000lb car feel it - no.
