Part 14
Some additional info about the brakes upgrade: The original brakes were equipped with brake pads measuring 2.25 x 1.5 inches for an area of 3.375 square inches (one pad). The Wilwood front brakes (part number 140-16946-DR) have brake pads with an area of 4.875 square inches (one pad) and the Wilwood rear brakes (part number 140-16680-DR) have brake pads with an area of 5.5 square inches (one pad). That is a increase over stock of 44% in the front and 63% in the rear. More brake pad area means more braking power.
The final two items I addressed in the makeover of my 75 Carrera was weight reduction and replacing the stock steering wheel with a MOMO steering wheel (which also took off 3 lbs).
The bulk of the weight reduction was in the front trunk where I removed the collapsing spare tire (48 year old rubber - never going to use it, 35 lbs) and the electric tire inflation pump (3 lbs). Next I replaced the Lead AGM battery with an Antigravity H6/Group 48 Lithium car battery (15 lbs versus 45 lbs - 30 lbs savings).
The CIS to ITB EFI conversion trimmed 10 lbs out back (heavy CIS fuel distributor versus billet Aluminum ITB's). The billet Aluminum Wilwood brake calipers versus the steel stock calipers saving 3.5 lbs at each corner for a total of 14 lbs.
In total, I was able to drop 95 lbs off the weight of the car (lighter is quicker).
