I’ve got both Racing Brake and Z1. The Z1 rotors gave me a vibration the first track day I used them.

I have the RacingBrake 2 peice rotors. They are a bit $$ but worth it. I'm on my 3rd set of pads, and haven't done a thing to the rotors. They use a different grade of cast iron then anyone else.

Mothra108 liked post by SoCal 370Z On thread : DIY: Oil Pressure Gauge

I'd rather have a factory oil pressure gauge than the digital clock in the triple dash cluster. I always, always, always warm-up all my vehicles before driving. Great thread = rep point!

That's the reason I paid a little extra for my SPL parts. People, it may seem expensive at first but worth the price and their resale value is high

I was thinking about them for a while as well, ended up going with SPL arms instead.

The letter irritated me a bit as it pointed the blame to the owner and installer not to them insufficiently assembling the joint.
