comment Assuming identical and sufficient ABS, and ignoring aerodynamics, are tires the only factor for braking distance?
Wow, impressive answer! This is what I was looking for. Two questions/points: 1. Yep I know a = F/m, so assuming a constant negative F, an increase in m results in an inversely proportional decrease in a. However, static friction being proportional to the normal force is F = m * g * u (coef. of static friction). Substitute in for F, and you get a = (m * g * u)/(m) --> a = g * u. So assuming the same tires, and brakes that can hold the tires at that maximum static force, I don't see why mass would increase braking distance.

comment If my brakes overheat, do they need to be replaced?
Awesome, I'll give you the tick because you were so comprehensive with talking about each part. Is there anyway to know if you've boiled brake fluids, or check the caliper seals?

comment Causes of early clutch failure EXCLUDING driver style
@RoryAlsop I imagine if someone rode the clutch badly, particularly if in a hilly area, you might wear the clutch out in that time. Back when I was learning I did a great job of burning the clutch on some poorly executed hill starts!

comment Why are drum brakes still fitted on Ford's cars?
"Slotted and drilled rotors are a compromise between ..." - they're not really a compromise when you take in to account the full set up of much larger pads and rotors. Interesting point nonetheless.

Wow you and Brian have both given great answers - I'm in a bit of a predicament in picking one! To me, Brian's answer is more comprehensive, but I see you've got a lot more up votes. Can someone else explain why this is so far the preferred answer?

Interesting, so you reckon pads will actually return to a good state after cooling but the discs may not. Hopefully we can get some more input on this.

comment Does accelerating faster worsen fuel efficiency?
I've gone ahead and accepted your answer as I think it gives a more accurate explanation. Rather than suggesting that the slower you accelerate, the less fuel you'll use (not true given fuel consumption at idle), it suggests that there is a minima on the fuel efficiency curve. As Bob said, you do need to consider wind resistance, which is greater at higher speeds and thus favours lower acceleration, though I don't think it would stop there being a optimum point. But really what this requires is testing the OBDII port while driving - may do that some time.

Wow what an answer. I'm going to need some time to have a good look at this, but I think this information is what I've been looking for!

comment What modifications need to be made to an engine to enable higher safe RPMs?
Oh I am... and I'm very much a big problem solver/engineer and have enjoyed athleticism. All a good recipe for a very successful and possibly obsessed racing driver! And that's why I tread carefully!
