At MV8 in Charlotte, NC, I came off Turn 4 at just under 100 MPH behind two cars with brake upgrades. As we dropped down onto pit road, I damn near tried to push the brake pedal through the floorboards trying to get it slowed down before climbing into the rear seat of CheeseheadBob's old car. My "Seat of the Pants" estimate is that Big Brakes are better and stop shorter under any condition. If my stock brakes were hot, I would have had to go into the infield to avoid running up the ass end of the cars ahead.
It was almost a Brown Streak moment. ... Almost !!
ABOVE is really "it" regarding brakes!
Can't compare track to road.
At track there is a need and designed area to slow, on the I80 to I5 five lane "suicide merge" when some idiot slams thier brakes on and nearly stops, instead of merging at 55 mph an hour as the freeway was designed... Which leaves only the precious 5-8 car lengths in front of you, THIS is where our brakes under-perform.
Any of us who have "Fred Flintstoned" our foot through the floor and created a "brownstreak moment" a few times -- knowing that any other car we've ever owned would have/could have slowed/stopped in much MUCH less distance -- can tell you our brakes are a weak on these cars.
How to fix this is where different ideas come into play.
We can all agree that bigger brake rotors and bigger sweep area combined with the mechanism to squeeze pads against that sweep area, is generally "better."
I am working on the buying the parts for the big brake kit now, and will do big brake upgrade to one car at a time about four weeks apart and compare them. It will not be entirely scientific data wise, as I'd bet the best accurate comparison will be the data in the differences (the area I DID NOT stop in) vs how many feet it took to stop each car.
So I'd expect the data to look something like/be similiar to this example: Big Brake -15ft, -13ft, -18ft, -20ft, -19ft. (Note: I made these numbers up for the example--not a prediction).
I will do five or six stops from 50 MPH in each and post the results.
Again, many factors will play into this and skew the data:
I will get better at applying the brakes
Brake harder or lesser each time
Brakes will heat up
I brake early or late
Speed changes slightly
Etc...
This said-- I fully expect the big brake upgrade to fully kick a$$ over the like new 17,000 mile stock brakes.
It may be March to May before I get to this-- but now I am very interested in doing so--as today is the first sunny beautiful Northern Cal 60 degree perfect day we've had all winter!
Unless somebody can do this sooner?
Thanks to Zack and Jerry (Gerry) for creating the upgrade!
