Formerly known as Modick Performance, Performance Improvements Pierrefonds is your source for performance auto parts, accessories plus the parts to give great fuel mileage for street, custom, sport compact, tuner, truck, and racing vehicles in Pierrefonds, Quebec, Canada. My name is Rick McHenry, manager for Performance Improvements for 22 years, first in Montreal when it was called Modick Performance. I had worked for Modick Performance from 1982 till 1988 and then we were bought out by Performance Improvements, it was a seamless transition. I ran a 1969 Camaro for five years between 1983 and 1987 driving it every day for the first 3 years then strictly racing. I have always been interested in cars and selling parts to make cars look good and go faster.
