This upgrade was a LONG time coming. I've been racing this car in earnest for over 5 years and have needed a brake upgrade for at least the last 4 years. I knew of several options that were fairly bolt-onish but at the same time they only offered a moderate upgrade over what I had...I wanted more. I wanted to only do this once and to do it right.
When I found out about the Stoptech Big Brake Kit Ron Sutton was developing and especially when I held the ST60 calipers in my hand about this time last year at SEMA, I knew that was the direction I wanted to go. All one has to do is to search for "brakes not stopping good" threads on any PT forum and you will see so many people not happy with their big brake upgrade kit's performance. I wanted to avoid that completely. If I was going to go thru the trouble to redo the whole front geometry to put a big brake kit on, I wanted it to be right the first time.
During the bed in process of the pads the first time out of the garage, performance was confirmed! The brakes are night and day different over what I had before and frankly, as good as any other car I've driven both on course and street.
Even though this system was designed for a manual setup, I am using the factory G-body power booster master cylinder (for now). I can rest my heel on the floor and with just my toes on the brake pedal bring this car to an immediate stop with just moderate pressure and pedal throw. Locking the brakes up is NOT an issue either.
It will take some getting used to for sure and I have a little bit of prop valve adjusting to do to dial in the rear brake bias...but I'm confident they would work great on course or on track right now as they sit. We may at some point in the future play with a different size power master cylinder or even a manual master cylinder but for now, they work just fine.
Unfortunately they won't be debuting in Topeka this weekend. My carb flooding issue is still present so it is coming off today and being sent off to remedy or replace. This saddens me but at the same time I'm super happy to have completed this total brake upgrade in a little less than 5 days total. That speaks to the quality of this package Ron put together and the fantastic set of parts it includes. This was my first attempt at a Big Brake install and while I learned some things along the way...for the most part it was pretty much plug n play both front and rear.
Thanks to Ron for all the help...and for developing the BEST Big Brake Kit on the market today.
