might throw the turbo on before everything else just to get it mocked up, and just cruise with it at the 10 pounds that the external Gate is already set to

The wheel technically isn't even designed to work with an S14 clock spring, as the locating pins are in different places. For other people doing this, I would suggest just modifying the wheel.
That's strange... I think 95 240sx in general are just weird. The clock springs are different and the power window system is from the stone age. My old r32 wheel (the one your brother has) fit directly on my s14 without modification of the clock spring or re-drilling the wheel. I just rotated it a bit so the peg lined up. I had no trouble fitting my old s15 wheel either, however when I sold it to +Waldo+ ( owns a 95) he couldn't get it to fit for the life of him so I met him and we compared clock springs on our cars and the 96 clockspring was definitely a different design. He ended up "modifying/breaking" his to fit properly as well. The aforementioned wheels also fit perfectly on my kouki when I had it as well. Go figure...?

This is wrong. Swept area is the area of the disk that touches the pad while rotating. That is, the area of a ring. = Pi * (R1^2 - R2^2), where R1 is the rotor diameter, and R2 is the rotor diameter minus the pad width or R1-pad. Make rotor bigger => make swept area bigger.
you would be correct if the pad actually touched the larger rotor completely, but the pad does NOT cover the same area of the rotor (actually slightly less even) because these rotors are NOT made for these calipers....From what I was told the pads hang over the top of the rotor just slightly???






But in a correct caliper rotor combination you would be ABSOLUTELY POSITIVELY CORRECT!

^^^^^^Burgy that is why I am not to happy with the new set up (I tough it was the spacers). Now in search of evo front calipers. On another page I did the front end .energy suspension bushings and lower control arm ball joints also paint the arms

Not to completely beat this into the ground, but I'm not affraid of doing math. 3mm of overhang in the first pic versus the 20-30mm the caliper has been moved out. 3mm versus the ~50mm of pad. I can tell you right now without touching the calculator that this setup has more swept area by FAR than a stock setup. The second pic, yeah that's just slop and doesn't go into the equation.

Are these the 350z brembo rotors or the Cobra rotors?

Pretty sure he's using the 350z ones, haha @ the swept area arguement.

Epstein what are you saying that the current set up I got work better than the 300zx rotor set up?

That's what they look like to me too. It's friggin math!

Here goes:
Z32 rotor is 280mm, pad is 50mm (from FSM). So, R1=140mm, R2=90mm.
Total swept area is 36128 sq mm.

350Z Brembo rotor is 324mm with 3mm of pad overhang (47mm pad). So, R1=162, R2=115.
Total swept area is 40900 sq mm. That is a 13% increase in swept area.
If the bracket put the caliper in the right spot and gained the 3mm of pad back, this number goes up to 43039 sq mm, and 19%

Just a little fun...
The real deal 350Z brembo setup is 324mm rotor with 53.3mm pad. R1=162, R2=108.7.
Total swept area is 45328 sq mm. That is a 25% increase over stock Z32.

And just to rub it in... Look what happens when we calculate % increase by just using the rotor diameters... (324-280)/280 = 15.7% increase. Pretty friggin close to doing it the long way, eh?

So Cliffs notes.
1. This "hack" setup increases swept area by 13% over the Z32 rotor. Yes, it'll be more effective in braking.
2. You're only getting about half the benefit versus running actual 350Z brembo calipers (regarding swept area).
3. Compare my corrected bracket number and the 350Z number. This is the difference that the extra 3.3mm of 350Z pad adds. 5%. It does make a difference, but not by a whole lot.


Hey Burgy, is batting average hits / at-bats, or do you take out the walks. What the hell is slugging %? Honest questions.
