SP20 big brake kit - Update, date etc

[twilightprotege]

yep, the abs will release earlier on dirt roads because the wheels are locking up much much quicker. naturally the stoppnig distance will be longer than bituemen.

abs may or may not stop quicker than a non abs car, but alteast you have the ability to steer around problems rather than plowing straight through them. i know i'd much rather avoid an accident than be involved in one

[wiredone]

so after all that was critter actually able to find out what they are off... so we can all go out and follow in his foot steps... i say lead the way... not everyday someone makes an effort to do a SERIOUS mod to the sp... makes me warm inside thinking me and twilight aren't the only "freeks" around here... lol (no personal offense meant twilight...=)

id love to have a set of these...

we recently did an sp down at the shop that had 18" rims with disks so big they filled them... didnt have the car long enough to find out about them... sad cause they were just ever so sexy... tempted to steal 'em...lol

my 2c... just waiting on specs from critter

[twilightprotege]

well i am an NA freek hehehehe - i'm now a mod of the NA performance section of the msprotege.com forums

i'll definately be getting a brake upgrade at the latest september....

[preeman80]

Yup, I still need the brake upgrade... Hell my car dont move but still I already think that the brakes looks so smal on 18"s.. hate to think how small they will look on 19" wheels

ok guys earlyier in the post chriss told us it costs about $1750 [or there abouts im guessing here] so that maybe a little to much 4 some people to folk out at this stage
so if you dont mind shelling out that sorta money well contact chriss an let him no, im shaw he will be more then happy to put you in contact with his people

[BigMal]

The only thing I and some of the others were waiting on was what car that the
rotors were coming off. I dont have an issue with the $1750 but I already have
the PBR callipers if I can get the rotors for around $700 I should be able to
have brakets made for around $300 saving me over $500.

[platypus]

and i was under the impression that abs worked by comparing the braking rates to each wheel on the same axle, while monitoring how fast the car is decelerating

abs is run off the speedo, and will not be active in most cars below 15-20km

get in a abs equipped commonwhore, leave the hand brake on and drive... the thing shreiks at you coz it thinks your screwing with the abs by locking the rear wheels but only when you get to the abs activation speed

[BigMal]

Dont think that question is something we can dump on Critter to answer thou.

[dfvadr]

mal do u no what rotors you would like i might be able to help you at a cheap price
i think the ones critter got where dba slotted 314mm blanks then drilll to suit stud pattern

[BigMal]

Based on the comments earlier it was either 324mm or 315mm both pre-drilled.
If you can get blanks would love a price. Ultimately I am after the blanks they
use on the EVO brake conversions that are 330mmx30mmx45mm. If not blank
I would even be interested in drilled in that size.

today i received this info in reguards to brake upgrade evo lancer 5 studs 320 x 32 x 43.5 plain disc $330 slotted r $380 an slotted and drilled r $415 each now twin piston calipers off a commadore i can get around $170 each with pads for a little more we can upgrade the pads to police pads which r bigger same as hsv, im just waiting for more info on 320mm /330mm by around 30 x 45 there abouts in blanks , in plain and slotted just to see if i can buy them cheaper sorry i took so long mal

[BigMal]

Is cool mate not like I got a spare $1k anyway. Am starting to think
more and more of just getting the GTO 314mm X 45mm X 30mm
and instead of stuffing around with redrilling just go to 5stud hubs as
my mags are multidrilled anyway. Those rotors were only like $150
each from memory and the money saved would almost pay for the
V6 hubs.. But please any extra info or prices would be appreciated
as prefer to know all the facts I can before deciding on things.

my mate got in a 330 x 30 x 43.5 ,5 stud off a evo lancer to have a play with i get it 2morro but seeing it is our canberra cruise i want have time to play around till next week ,

im going to see if the rotor will slip straight on to our stud pattern then i will pull one off my ss commadorre brake calipers off an see weather it will fit an bolt up ,if not how close it goes an how i can make it fit

[BigMal]

Dont go pulling a caliper off. I am happy to help with the research I will bring down one of mine on the cruise and you can try it. Give it to Mik when your
finished.

[dfvadr]

ok mal thanks that is a far much easyier an better way to do it we'll work sumthing out as too a cheaper option for better braking

[preeman80]

Can some one tell me what we are trying to buy, ie company, part numbers etc.. I MAY be able to buy at trade prices. just depends...

[dfvadr]

wnen i work out the pacage i will an u can see if u can buy it cheaper than me ,who ever can get it the cheapest thats where ill spend my money

[BigMal]

Can you tell me how much you can get DBA216's in slotted for.

Rod,
The inner hole on the Evo rotor is 69mm, the BA 1.8 is 55mm so is the 2L BJ but
DBA dont list the SP20. It may be similar to the 5 stud BA 2L at 72mm.

Ta

Mal

[dfvadr]

yes mal the sp20 is 55mm as well with a 72mm centre hole the 5 stud off the evo caliper is the same

mal ur calipers will not take a 32mm disc, the 1 i have here is 32mm an ur caliper will not got onto it, an like sum calipers that open up this 1 will not an is only good for 30mm

so as i see it here so far im looking for a 330mm x 55mm x 30mm ,with a centre hole off 72mm
now the calipers go no where near bolting up with out making up a new mounting system which wont be hard , but you would need engineers then

[BigMal]

Rod
This is what I have been referring to.
http://www.dba.com.au/dba_catalogue_.../Out/Mazda.pdf

The 55mm I mentioned was for the centre hole not the overall thickness but
that was for a 2L BJ not the SP20. The 2L BJ is listed with a 47mm overall
thickness against the 45.5mm for the BA.

Thats a shame about the caliper. Have you seen the police pads at all. I have
looked at the standard HSV Clubsports and the caliper is the same PBR by
looking at it I am wondering if the police pad may be a little thinner being that
its almost twice as long and that is how they fit on the 32mm rotors.
Here's the holden catalogue as well.
