Can't go wrong either way! It just depends how much you track. Pads are cheaper and quicker to swap. I have it down to about a minute a side, no pins as well which help.
We still have our spiegler lines in stock, extremely high quality, factory fitment and more. We have a ton of kits out there with not one issue.

For over a decade I've tried many oils. I do oil analyses on every car I own as well as many customer cars. The ones I've found to do well have been Amsoil, Motul and Castrol.
I was also a big fan on Penrite oil but it's hard to get now.
It's nice that if I was in a pinch I could grab some...
