When I first put stainless lines on my car I couldn't feel a difference. The stock system is real good the way it is but if you plan on braking hard and frequently like at the Dragon then upgraded pads, fluid and lines are worth it. The stainless lines help the feel of the brakes just before ABS gets involved i.e. at the limit of braking traction. Until I'm are at that limit, I can't feel a difference but once at that limit it's easier to threshold brake. They are also more resistance to rocks or rubbing, should it occur. With ATE Blue, Motul or equivalent Dot 4 fluid the pads will overheat and fade before the fluid. I say this because it happened to me. If my car was a daily driver, with occasional canyon runs, I would replace the fluid and put better pads in the calipers. The stainless lines .... most don't use the brakes hard enough to benefit from them. If the pads overheat they pretty much melt away and loose around half, not all, of their stopping power. If the fluid boils the pedal goes to the floor and you have no brakes. From my experience and point of view, Dot 4 racing fluid, pads suited to how you plan to abuse the brakes, stainless lines last. If you overheat the brakes after all that, brake ducts to get more air for cooling and last but not least, bigger rotors and calipers for better heat dissipation. As far as slotted or drilled or both as long as you don't overheat the rotors they are fine and give better initial bite. I can't imagine anyone overheating them on the street but if you manage, they will get stress cracking and be ruined in no time. My slotted rotors still look like new after almost a year of track usage.

I stayed at a Holiday Inn Express and have Stoptech's on my Crossfire (355 mm slotted front and stock size slotted rear) with Carbotech pads, stainless lines and Motul 600. I need a closed face helmet to keep my eyeballs from getting lost.
