*Brake Pedal Ratios*
The OEM Tiger/Alpine brake/clutch pedals have a mechanical ratio of
approximately 4.4:1. I've been making kits for quite a while that
modifies this ratio to 6:1, which is pretty much the standard
aftermarket ratio. This gives you an advantage of about 1.36 over the
OEM Pedal. This is almost as much as the vacuum booster gives you.
I also make this kit for several master cylinders from the OEM Girling
to "new" Dual Masters from 13/16 to 1" diameter. Using a 13/16 diameter
also increases your hydraulic ratio. The kits are complete, but you must
send me a Tiger brake pedal (Alpines have a different bend) and the
Pivot assembly. I can bend an Alpine pedal to near Tiger specs, but not
"perfect". The process is reversible with the exception of the Pivot
which I modify. I typically make several a year for Dale's customers.
I have also run my 6:1 kit with a booster and autocross pads, but be
sure your seatbelt is fastened.
ALSO:
from a post a few weeks ago, Tom now recommends the Tilton slave
throwout bearing..
