Im not sure of the chain, I bought all my parts from Pete at the RS Barn. I know Pete knows his stuff so im confident it was quality stuff. Yes i changed the upper and lower pads and boy let me tell you it was a real Pain in the A-- !!!! I ended up compressing with a C-clamp and using a heavy duty tie wrap to hold it together. That was the toughest part of the whole job. I was really sweating before starting, but i turned it over by hand to be sure it turned over freely before actually cranking. Runs nice and smooth now.
I also bought an Exhaust,upper and lower braces,chip,K&N filter from Pete and moded the airbox as well and it really woke the car up. The only thing was the exhaust was far from a bolt on!!! I am electrician and I have a Hydraulic bender and I had to use it in a couple of spots to get the exhaust to fit correctly. When i really hammer it the gas in 1st gear i can hear it hitting the rear sway bar, at least thats what I think it is. I have to ck and fix it. Thats the bad news, the good news is that it sounds Aewsome!!!
