Pics of my car...getting lots of makeovers., 7th gen short shifter installed Options

[lubu]

Doing some major mods on my car, will update this thread regularly...










BTW im doing a gt4 conversion i already got the gt4 hood but im tossing between the stock gt4 and the c-one bumper (pic below),which one shoule i get. Im thinking of c-one...

I was going to do just that, but I decided against it because:
a.You will need to cut the mounting holes (areas) completely off as shown in the pic above, other wise the difference is too small to make a bracket.
b.You will not lose much (if any) surface contact even if you trim the rotor down to 297mm.

Heres why:




The outer circle is of course the original 315mm rotor and the inner circle is the 297mm trimmed rotor.
Now the surface contact between the pads and the rotor is in red, even if you extend the diameter and use the bigger rotor the surface contact will pretty much remains the same.

...and there is an advantage to the trimmed rotor, it weights less

let me know if my logic is wrong.

Yes it is.
The more stopping power is not given by the surface contact (the resistence will be preety much the same if you have 1mq or 1cmq in contact), its given by resistence x half diameter. If you have the same caliper, with the same pads and different rotors the more powerful one will be the one that byte the rotor farther for thehub centre.

So, using bigger rotors with the same brakets is useless, but making a braket that make you use the full potential of a bigger rotor with the same caliper is the better option, giving the better result.
