I'm too lazy to remove mine too so my jack/etc are almost always left in as well. Only on longer trips when i bring a full size spare do I remove it (because I don't bolt it down).

So what I'm getting from you guys is....a 400 pound weight reduction is not significant on this platform. Neither are NA engine mods. Not sure I buy that this is all there is to the story but ok.

Different driver...#1 mod in racing.

Weight removal makes the car faster. If the driver can extract those gains is a whole different story. I know Robi is no amateur, but that could be the difference.

Could also be the willingness of the driver to turn that fine-tuned machine into a ball of recycled steel.

Somewhat off topic since the OP wants to save weight in the brakes and I feel this is a fairly dangerous to do especially since the OP cares about performance. For repeatable performance, proper braking system is required. While 400lbs makes a difference, I wouldn't take weight out of the brakes. The importance of this topic lies in saving weight at the brakes. We can fade the stock brake caliper and rotors with race pads on a downhill canyon runs. If you can do the same, then perhaps running smaller and lighter brakes is not the proper setup to go with.

If you were to do a drag race between Robispec's car and our car, you won't see very much difference. If you want to smoke someone, running FI is the best way to go.

I have no idea how you are getting fade in the rear brakes. I have the lower spec non US spec rear brakes, solid discs, run TRD pads and I can't even get the damn things to wear. That's on semi slicks as well.

I don't know your driving ability or experience but I'm going to guess it has something to do with the link posted above. Its obvious that this car offers way more performance than most people can extract and I've seen plenty of videos of BRZ's with minimal mods keeping up with caymans on track days. Obviously the cayman is a faster car so the difference must come from somewhere. If you think that brake setup is right for you, then go for it, personally I don't think its the best place to lose weight.

Fading rear brakes might be a little difficult to feel, but looking at the braking system as a package, you can improve braking performance and longevity (small benefit) by utilizing the same braking compound front and rear. For example, running Carbotech XP12 front and rear, not just the front. With excessive front bias, getting the car to rotate during trail braking takes a little more effort to achieve properly. Even with the pedal dance, it is still not ideal.

This is utilizing Hankook RS3 + Project Mu 999 front and rear will give you, which is proper braking at all 4 corners. My right front rotor cracked right after this shot.

I still prefer a higher cf rear pad.

:o even I don't go there!

Many S2K people thought I was loco for running higher rear tire pressures than the front for autocross and track use.

According to them I should have spun the car multiple times. For the record, it never spun.. ever. It needed more rotation

With S2K stock aero though I'd *guess* that a more agressive rear pad and high speed braking would be... interesting. BRZ would be a lot better though but I've found equal pads to work out pretty well so far.

That is an awesome pic!

It annoys/amuses/intrigues me how Nürburgring times always say "this car did it in x minutes and y seconds" and rarely mention the driver.The drivers posting those lap time are not your average driver cruising about town. No car is going anywhere without the driver.

That's not evidence of anything. In a novice run group I could keep up with a Cayman in a stock Yugo on snow tires.

Ok maybe not, but the point is, driver talent varies so much that a BRZ with OEM sized brakes keeping up with "faster" cars isn't evidence of the cars performance.

I think I either presented my comments poorly or I'm being misunderstood. Either way I agree with you, the driver plays a much larger role in a cars performance than modifications.
