hey guys

fitted my EVO brembo rear calipers to my magna the other night! was told a simple bolt on right? HA! stock bolts were M10 with a 1.25 pitch thread and the brembos are a 1.5 pitch, so thankfully bunnings had some to suit at 10 minutes to 9 at night! then the caliper was just binding on the mounts so had to grind a little off the back of the caliper to fit, and the last pain in the **** was setting the handbrake in the street at 11 at night!

was worth it, the car stops way quicker and should help my "turn in" at the racetrack. most importantly they look the bomb!

sorry about the average pics, dirty car and just in the driveway

****in' SWEET!!!

What have you got on the fronts again? That PBR kit? Hopper Stoppers?

he has the hopper stoppers and looks awesome dude, how much did it set ya back if you dont mind me asking?

Where's the fronts? :nuts:

Nevermind.

umm was around the 900 mark for everything including brand new 4000 discs.

yeah still have the hoppers kit on the front and they do the job

nice definitely look the part and by the sounds of it do a great job aswell

Nice.

Are those rear Brembos single piston? or dual?

you can see in the pics they are single.

you can see in the pics they are single.

Nah theyre twin.

thats what i ment.

that baby pulls up with eye popping power!!!

Brembos are so 2007.. where have you been? :P


Bout time u got yourself sorted.. they are the best mode i did and have all the wank factor too..:P

looks mint mate, wish i had the money to do it!!!

thats what i ment.
Suuuuure you did. Just like when you said you were single, then you introduced me to your boyfriend :bowrofl:

hope those bunnings bolts are high tensile...wouldn't want them to fail....looks cool but.

Bigger brakes shouldn't help a car stop unless heat is an issue.

If you have the ability to lock up your standard brakes, then they can stop the car just as fast as big ones ;) Once they have had to pull up a car from 160 a few times they will get hot and spongy where as better quality brakes will last a little longer.

Also, fitting larger rear brakes will root your brake balance because of the hydraulic ratio between the front and rear of the master and the brakes that it fills.

Already upgraded the fronts to these monstrosities.

Looks good, from personal experience I'm well aware of how silly having much larger rear brakes than the front looks:P

I'm curious as to why you say they should help your turn-in, since you shouldn't be on the brakes when turning in:nuts: Though in some situations having light brake pressure can help.

Btw the upgrade shouldn't affect brake bias, as our magnas have EBD anyway. Unless the old rear brakes are overheating badly and fading badly (unlikely, given there's bugger-all weight in the rear of our cars).

To which I say bzzzt. I left foot brake deep into apexes on track days and somehow I always finished up with FTD at BMW track days......:badgrin:

Depends on the track/car setup, I know both the car and track we are talking about here :P

While it's common practice with properly setup fwd's to brake deep, at turn-in if there's still any braking it's generally only gentle trailing brake, IMO not a situation where bigger rear brakes are gonna make a difference.

burn!

just remember not to brake to hard when in traffic or you will end up wearing the car behind you, LOL.

fwd need a rear brake pedal like motorbikes. If you use the rear brake on a motorbike in a corner, it can help to stabilize the bike and improve turn in.

Keep in mind the chassis dynamics of motorbikes are rather different to that of 4 wheel cars, with roll centres at each corner.

In a nutshell a properly setup track FWD should be prone to haveing a bit of oversteer on turn-in for fast corners. However applying rear braking is not the way to go about it, as you will drop speed and probably cause instability due, to having excessive rear-front weightshift during cornering.

What you want is relatively high spring rate to minimise squat and roll of the rear, this actually maximises front-end grip by transferring more weight to them, mainly the outer wheel. The small amount of rotation of the rear is a much smaller benefit - on tarmac at least, on dirt it's a different story, where you can slide enough to actually greatly reduce the turning angle of the front wheels by swining the rear around.
