How much do the stock FD rotors weigh?

http://www.modified.com/projectcars/...t_3/index.html

they did a brake swap and they say the stock rotors are 15 lbs each for the fronts and stock calipers are 6.20 lbs

Those these ebay ones are way over weight lol they swaped some porshe ones on that car and they weight little over 20 lbs for rotors for same size as these ebays

OE G37s rotors are ~29.5lbs according to racingbrake

Actually, I think you have to drill out the FD mounting points vs. Evo.

I say this because if you look at how you mounted your, the caliper mounts towards the wheel side vs. stock back side. If you drill out the evo side, then you would have to bolt thru the front side which you might have problem with... I think it would be easier to just take the thread out of the FD side.. But again, I'm just guessing via poor cell phone pics.. :)

That was a pretty neat writeup. Sounds like a good brake system.

has any one on this forum done this swap? were the brackets 1 off parts or are they a production part? it would be great if someone made these brackets so we could build a cheap bbk

Centre bore is negligible, Id say they would fit quite snuggly :)

G37 66.2mm
FD 67.1mm

d = 0.9mm

as for the 'cross over tube' I dont believe it will matter - brakes are hydraulic and will be under pressure - it'll work no matter what way up they are :scratch:

WOW! 0.9mm?? That's almost nothing.. LOL!

I now understand what 'cross over tube'. I also agree.. I don't think it matters.. But I'm no engineer :)

yup...i just had to sand the rust off the center of the hub of the FD and it fit on tight as a glove

Good stuff. Jumping on to follow the action.

the total diameter of the rotor with the caliper on it is about 15inches...but i would have at least a 15.25 to 15.5 inches of diameter inside the rim

This is the greatest discovery of this decade. You have my vote for the FD Hall of Fame.

So this wont fit under a 17inch rim?

He just stated...

Different style rims have different inner diameter. Best answer is to measure your own wheels. Better yet, to help others, post what kind of wheel you have and the measurement you get :)

curacaosfinest, To be more accurate, can you put a ruler and snap a pic so we could see the radius from the center of the wheel to the edge of the caliper?

Waiting for more pics of this set up..

i was thinking it was probably easier for you guys to measure the diameter rather than the radius cus its hard to get one edge of the rule exactly in the middle of the wheel

but i will take a bunch of pics with the measuring tape

the pics are coming guys, so sorry to get u guys hyped up before i installed everything lol....i'm just waiting on brake pads to come so i can put everything together

oo and if there is any real concern about that crossover tube, it can be unscrewed and switched with the bleeding nipples...but i just dont get how to bleed this system, do i bleed it from both nipples? or just one? or one at a time? can someone shed some light for me please!!!

Bleed from the inside, then outside nipple for each calipers.. Start off with the caliper farthest way from ABS (driver rear) to closest (passenger front).

There is also some pertinent brake information in the article for anyone thinking of upgrading.

It never shows the picture of the caliper, but from SCC memory and the little bit of the caliper I can see it appears they are the Porsche "Big Reds". I run them on my track car. Fritz has also run these(I bought his set). Damian use to have a set that he tracked as well, which he sold to Andrew(GooRoo) and are on his car. I personally think it could be a cheap BBK. You use the 993TT Calipers and rotors. And you have to have a bracket made to fit the calipers on our cars(which an automotive machine shop should be more than capable of doing), and a custom hat made for the rotors to fit the offset(which Coleman Racing can make). BTW, at one point I fit these under my 17x8 Mazda BBS RZ wheels without issue.

If this was a problem it would be because the right caliper is on the left side ( or vise versa ), if the bleeder is on the bottom, just switch them. It does matter because it the bleeder is on the bottom they could be a bitch to bleed. I know this because the guy I bought the car from had the front calipers reversed.

ok guys i decided that i'm going to drill the threads out of the FD's mounting holes

the evo has the same size 12mm bolt but a different thread, so i'm just going to shave the threads in the FD's mounting holes until the EVO's bolts slide through but fit snuggly (no play room)

whatever you guys do dont go and get OEM bolts, i priced them at mitsubishi at $8 a bolt! and $3 for a washer!!

i went to my local machine shop (hardware stores dont carry this bolt size) and they had bolts in the correct size M12-1.75

i picked up 4 bolts, 4 spring washers, and 4 flat washers...make sure you hardened steel bolts
i payed $7.89 for everything lol...

heres a pic of what i bought
Oh and i hope you guys know that all the pictures that i post up are clickable thumbnails to the full size photos

ok guys i re-mocked up everything to try and work out any issues that there could be now so when i'm ready to bolt everything in, it goes smoothly

i took a bunch of better high-res pics so you guys could see

uploading them now...ALL THE THUMBNAILS ARE CLICKABLE TO LARGER IMAGES!!!

i wouldn't presume to just switch them unless the pistons are not staggered

Thanks for doing all of this, I think I might try the same thing. However, I'd want to clean up/repaint the calipers before putting them on. Anybody know the best way to do this w/o losing the brembo logo?

Hi curacaosfines,
what ebay stor did you get the disks from iv tryed to find them and couldent, how soon before you can try them out?

the pistons are staggered...i switched the nipples and tube today, so now the larger piston is above and the smaller piston is below
