I'm pretty sure my Boss still has the stock pads/discs and so far, I'm not overly impressed with the performance.  The initial cold bite is not very strong and even when warmed up, overall braking performance seems low.  I did try a couple hard stops from about 60 mph when the Track Apps was active and the best braking G-force I recorded was .97 Gs.  Granted, it was only about 50 degrees out, so tire grip was not very good.  (New Goodyear Supercar F1 tires in stock sizes.)  I'm just wondering what others have seen as their max braking G force, as recorded with Track Apps?

 

Thanks in advance,

TK6

Good question.

I have the 2012 LS Guage Pack and will have to look at my negitive G force when braking. Still have OEM pads and rotors but I did improve braking performance with Hi-Temp Dot 4'brake fluid and SS/Kevlar brake lines on all 4 corners. This upgrade made a big difference in brake performance and pedal modulation.

Don't know your mileage or maintenance history but I would recommend changing the brake fluid and bleeding system with Motul 660 fluid.

Yeah, I will be flushing the fluid with good Dot 4 before any track days.  I'm mainly trying to figure out if I want to spring for some Pagid pads.  My plan was to keep this car stock if possible, for street use.  The car has 18,000 miles on it.  It did sit for a long time at the dealership as they wouldn't put it up for sale until the airbag recall parts were available and the rear rotors got rusty.  I've just been driving it normally and the rotors are almost back to "normal".  I'm just used to my old C5 Z06 and E36 M3, which had "throw you against the seatbelt" initial bite!
