You know the weight of the car.........do you know the current clamping force of your brakes?

Bob --- 20's front and 10's rear


Wore a set out in 2 good long weekends of running pretty hard (road racing not that wimpy Auto X stuff). LOL. The fronts were down just to where there was a little left in of the wear slot. I just change 'em out when they're that close to be done. Pads and tires and oil and fluids are just consumables and part of the cost of doing this super fun stuff!

I run Hoosier A7's and the car is ready to go about a third of the way around the track - it's the autocross tire and they need to grip immediately with those roaring 40 second runs - versus the R7 road race version. It's all about the tire temps... and we keep a very keen, educated eye on those every session. So far I've been able to keep running on the A7's... as I learn to be a better driver and built more heat (more speed) - then maybe I'll be forced to move to the R's but not so far. The numbers don't lie... and the tire and rotor temps tell it all.

Sieg,
need to check my info on clamping
as far as weight not sure.. but roughly 3500 lbs now-- was 3710
My buddies and I are talking about getting a set of
scales as we are all messing around with our car setups now
plus I am still reducing weight as time goes on

Greg,
thanks for the feedback.. I run bp 20s both ends of the Pantera
but a lot of braking does come from the rear due to the mid engine
I am finding I can get maybe 4-5 track days on the pads since changing
to the bp 20s... I like the better pad and agree changing them out
more often is not an issue.. also change the fluid at least once a year

I remember you stating you ran the A7 tires... I have run r 6s along
with Kumo v710s for years on the Pantera.. almost always track days as
that car does very little autocrossing... just recently switched to a
Hankook front tire... SCCA spec tire for sedan cars and it really makes
the car stick better

Searching and changing things are not bad if you can get some
feedback and testing time.. need more testing time in the bird

Pantera always comes first.. just finished the clutch last night
so I can go to the Historics next week with the Pantera group
two cars is sometimes a pain figuring out

Buy your stuff from Sutton or Kore3 and they'll do the needed calcs to insure you're actually gaining ground. :thumbsup:

Wilwood brakes
 

I think Sutton since I already have 6 piston Wilwoods
on one end... need to do my homework to figure out
weights, master etc... Pantera is running again and
we have Canepa this weekend and Monterey Historics
next week so the Firebird is on the back burner again

Thanks,

Bob

Get the data and act accordingly! :D :thumbsup:

I need to put some front brakes on my Chevelle. Already have the disc/parking brake drum combo from Wilwood out back 12.19".

Is the cost of going to a 14" front brake worth it? I'm guessing the car will be around 3800lbs.... hopefully less. Alum turbo'd 5.3, T56 Magnum, 50lb twin disc clutch, heavy 9", full cromo cage, heavy CTSv power seats, a/c and p/s with 25 gallon s/s fuel tank. I have the ATS front spindles with ZR1 hubs on it.

Looking at Wilwood 6 piston 14" fronts.... are the C6 Z06 vette brakes cheaper and just as effective?
