SP20 big brake kit - Update, date etc
 

I have a VERY good contact at Specialised Brake and Clutch in St Mary's in Sydney.

Was speaking with Chris the other night about producing a big brake kit for SP20s. Chris has a LOT of expertise in this area, builds race cars including for Rick Shaw etc etc.

Anyhow the idea is to do a kit that would be suitable for ALL SP20 guys, this meaning it needs to (just) fit inside a stock 16" rim.

Reason: some have stock rims, most have stock rims as a spare even if they run 17s or 18s on the tarmac. It does after all need to fit inside a spare wheel if you need the spare for some reason :)

Will be looking at the options closely with him shortly with a view to maximum cost-effectiveness: strong performance at moderate price and good looks inside all those pretty rims.....

It is expected that the set-up will most likely be a DBA slotted rotor of about 304mm with PBR alloy twin-spot calipers and kevlar (probably EBC) pads as well as Motul 5.1 brake fluid.

Cross-drilling is thought unnecessary, one or two piece rotors amongst the options (one piece cheaper, not much different in performance). An RX7 FD103 caliper MAY be an option. 4 spot calipers are too exxy I think.
Rear brakes? Thought unnecessary but will get some prices on a simple slotted rotor and pad combo. I think just a similar pad to the fronts will do the job.

SO.....
What I am looking for is 2 things.....
1. Expressions of interest in the project. I already have one other party keen.
2. A spare wheel from someone's boot to fit it up to. Would only need it a couple of days if we co-ordinate properly. Why not mine? Anyone who has seen my boot knows why I would prefer not to if I can avoid it..... :)

Do you have any idea what sort of cost we'd be looking at?

And I'm happy to offer up my spare for the fitting. :)

I was thinking about bigger better? brakes.. Since I got my new 18s the brakes just seem out of place :wink:

Hi all,
As far as i know the suspension in my BG SP is the same as that in the BJ (not sure for SP20's). I am already running 16 inch wheels (see wot i am getting at) so a set of fronts sounds promissing (if i blow a front tire that will mean taking one off the back, putting it on the front and the spare on the back - but I can live with that). If anyone knows if it would be possible to fit these brake to the fornt of my BG please let me know.

SP20s run 5 stud pattern, does yours?

Cost? that we have to find out.

Zed, I'll pm you moit :) Onya.

hey chriss sounds like an idea there but i would not build up some-ones hopes buy saying im interested without no-ing costs
i have 4 standard wheels sitting here i could even drop one 1 off as i go out to st marys a fair bit

nup she is a four stud

oh well good luck anyway

thanks guys

you know i'm in chris :D gimme gimme gimme!!!!

my wishlist : 2 peice slotted rotors up front, replacement slotted in the rear (single peice). definately minimum 2 piston caliper upgrade radial mounted (pls pls pls radial mounted)

Hi Chris,

I am interested as well.

Hi Chris,

I am interested as well.

OK then.

Probably easier then to have Rod drop one by since it is is in your normal run of things. Thanks muchly Zed just the same.

I'll have a word with Chris at SB&C to see about timing so it's not hanging around the place, he said to just give him some notice so he can have the time for it with other things going on.

I'm sure we can have a range of options, say....
One piece slotted rotor + 2-piston caliper + pads"x" + brake fluid = $X
Two piece rotor, same rest = $Y
Same again with rear rotor + pads "x" = $Z
and so on

Because we have a club we are in a position to negotiate with a number of "kits" and I will go down that road with it. If we can start with say 4 or 5 first starters I think that puts us in a stronger position to make that point and it looks like we probably have :)

Will get back to you with progress and I'll be in touch odd12c for a suitable day to drop off a rim. Ta all!

sounds like a good plan (price structure)

Would be interested in upgraded calipers for a BA

I have single peice slotted dba rotors for the front anyway and really only interested in a front caliper upgrade.

The BA V6's have a five stud pattern but I'm not sure of the exact stud pattern.

Would be interested depending on $$$ and if they are able to fit.
Will be away for a month shortly so won't be able to give input or anything, but am interested nonetheless :)

Takes that on board :)

Latest update....

odd12c is taking a rim to Spec B & C for fit-up in the next couple of days. Onya Rod!

Once there and the fit check to the rim is done I will get my car down there and fit up/offset on car and we will have the options and costings available.

Prolly sometime next week. Will post up the $$ and choices. They should know how that compares to BA front end.

dropped wheel off today he had a quik look said its looking like a 315mm dia rotor

told him no hurry for the wheel have a play so we wait for an out come soon

also that dia is in a 16" rim [standard sp20] so u guys with smaller rims r outta luck but as i see on this forum most poeples r running 16,17,18s anyway
but dont forget ur spare if u get a punture an have to put that 15 back on

rough mesurement puts the standard sp20 fronts at 260mm so a 315 is giving us a 55mm bigger disc thats a lot off extra breaking [im excited lol]

Onya Dude!

I'm more than interested!!! gimme gimme gimme!
