SP20 big brake kit - Update, date etc

[preeman80]

Guys, any updates on this???

[TDK]

I hope this project hasn't died in the a$$. That would be a shame, considering that there is a quite few people interested.

[twilightprotege]

from what chris told me, it appears the problem was the price. it was way more than what he was originally told

[Critter]

Yeah, the cost is pretty high.
The "overtures" were one thing, reality something else.

That said, the big brake kit works very very well and looks as funky as hell.

Price fitted was $1694. This was for 324mm slotted rotors (315mm same price) and HSV Premium twin spot calipers and pads (by PBR) with Motul 5.1 brake fluid. The fitting cost was around $500 and took ALL day (it's a big job on our cars).

[BigMal]

I was quoted $1700 for the fronts from Racebrakes and $1500 from Gavesport.
I bought some Commodore/PBR callipers a while ago and if I can score a pair of
rotors for around $500 know someone who will make the brackets fairly cheap
so hoping to get it all for about $1000. Still a bit of money to have spare.

Chris, is that $1694 for front and back or just front.

[twilightprotege]

thinking of good alternative calipers to setup a system with, what are out there? obviously the commondore stuff, how much are the import stuff from say nissans etc? what other 2nd hand caliper options are there?

Galant VR4 is popular with the laser boys

[twilightprotege]

i've really love 4 piston calipers if at all possible (that's why i was thinking like brakes from the r33 gts-t etc), but i know the price pretty much doubles for them.

i guess once i have the calipers, a place that knows what they are doing can pretty much make up any bracket required....so long as there is enough increase in disc size (from what the ppl at competition friction told me, that's 304mm discs+)

[BigMal]

Critter how much were just the rotors ???
These are 324mm x 45mm. Are they blanks with no holes so we can drill them with 4x100 stud
pattern. What was the inner hub size in the middle of where the stud holes are.

[Critter]

The rotors were $295 ea plus GST, they are DBA stock items, pre-drilled etc.
Calipers were $285 ea plus GST including the pads.

Fronts only.

After over 60k the rear pads are still only about a third worn....the rears are basically "going along for the ride"....

[BigMal]

If they are a stock item what were they off, a Mitsubishu GTO ??
That was the closest thing I could find on their catalogue.
You can get a 330 x 45 blank rotor thats what Racebrakes and Gavsport use.
They use them for an upgrade for the EVO's can you ask your friend
if he can get them I would prefer not to weld up and redrill a set of rotors.

Twinlight,
I tried using GTO rotors and callipers but you only have less than 5cm from
face of rotor to inside of mag wheel. Change to the larger rotors and the
gap reduces more. The 4 piston callipers are heaps wide and not even with
a huge spacer plate could I stop them hitting the mag.

[Critter]

Not sure what they were originally "intended for" Mal.
I'll try and find out.....

[BigMal]

Thanks Mate, Appreciate it

Mal

[twilightprotege]

cool mal.

btw, you're really going to have to stop referring to the rotors as 45mm wide, i get so confused!!!! esp considering i want 2 peice rotors, so the hat is custom and determines the offset etc, the rotor itself is 315mm x 28mm etc

[BigMal]

The problem I have with that is that all 28mm rotors are not the same. If
the overall thickness is not 45mm eg a commodore rotor then even if it
did fit on the hub, it would foul against the strut or put the wheel way out
of the guards. Having a 45mm overall thickness means it will sit close
enough to factory on our hub. I dont know about you but to me getting
that right matters a lot. If you want me to refer to it in a AxBxC
measurement then I can. Have a look at the DBA catalogue on
www.discpads.com about those measurements and how many 28mm
rotors there are.

Regards

Mal

[twilightprotege]

that's the problem. you're talking about single piece rotors, i'm talking about 2 piece.

but still with your measurement, 45mm means squat in terms of braking capacity. for all you know a 45mm rotor, the swept area could be 8mm thick. atleast talking in terms of the swept area thickness (ie 28mm etc) you know what braking capacity the rotors will have....then you can talk about offset later

[BigMal]

Best of luck with the 2-piece they are around $550 per corner, that plus your
4 spots you will be saving for a while. Luckily Critter knows what I am talking
about. I will use the AxBxC specs from now on so there is no more confusion.
I am talking about a blank 330x45x30 or 330x45x28 rotor with as close to a
55mm centre hole as possible.

Sorry guys, have to ask a dumb question. ops: This doesnt effect ABS etc in any negative way?

[twilightprotege]

not in any negative way no.
