Thanks DakarM for the explanation.

I tracked the OEMs and it doesn't hold up so well, even with some decent Michellin Sports (OEMs)

Reason I meant by better grip with bigger is that I'm going FI soon and I need to transfer those as much to the road as I can. Udersteer can be balanced out because I can induce more oversteer to counter that with my latest suspension setup.

Also, my brakes, even with Dimpled and slotted rotors, better Goodridge SS Lines, Endless pads, and Motul RBF600 fluids, it cooked after two runs on the mountain. BBK will definitely help with the fades and cooling. I gotta admit, this is also my All Show & All Go project, that's why I'm going to get the BBK (Hopefully Endless )

Also, I'm just saying what I read about Rota company. I know what ISO mean, but at least that proves that they do have some quality control. My company had to go to ISO 9006 Audit and a lot of quality assurance and control had to be done in order to get certified.
