Front Brake Selection Help! 1970 Trans AM

[Ron Sutton]

"I'm still trying to figure out why Wilwood's standard 10.75 rotor and Dynalite caliper is an "upgrade" over stock discs other than lighter as it has been advertised over the years.
This drag race front set-up doesn't offer more braking than the stock set-up, just lighter rotational weight & lighter overall weight.

I've got them on the 79 Camaro drag car with 2.5 metrics on the rear with the TA rear discs BP-10s on the front and some Bendix FE organics on the rear but it has skinnies on the front and bigger slicks on the rear. 1.032 Strange MC."
OK, I worked up a brake calc sheet below.



Manual MC, pedal ratio 6:1 -or whatever exact the upperhole gives you on the pedal.
I won't know what your brake pedal ratio is. So the calculations are only as good as the information input. If you want to know for sure, go measure your pedal.

Wilwood 1.75 four piston Dynalite calipers.

A factory 11" with the big single 2 15/16" floater is probably a better brake other than the weight difference.
Sure it is. The drag race front set-up doesn't offer more braking than the stock set-up, just lighter. Besides, it's hard to use all the braking force possible in the front with skinnys.

Not sure the 12.19 Wilwood rotor will fit the 15x5 ProStars.
I have no idea on fit. Not my area.

Here is the chart.
