vz brake upgrades

[Archers]

hey guys i got a quote for ve brake upgrades for my vz consisting of complete front upgrade to the VE spec 322mm slotted rotors, new calipers, new pads, new brake lines and fluid and i would just put slotted on the rear as 90% of braking is done on the front the rear is just to stablise the car, any way my question is

is it illegal at all? as my insurer is fussy thats why i want to make sure!!



thanxs for any input

if i was you i got to the NVU website and check out there brake packages for the VZ. they got HBD and HSV. and youll find the rotors be slightly bigger in diameter. then you will have no hassle.

guys i got some brakes that im gonna get what im asking is it illegal [ defect] for have bigger brakes

[GTRwilson]

i cant see why upgrading something to make the car more safe would be illegal?

Just ring your insurer and ask if they will void your policy. Have you rung the RTA or who ever you guys use?

cant see it being a problem considering the VS boys are running VT front calipers and rotors?

Has anyone had any experience with that HBD kit?

Yes it's illegal any mod to the brke system has to be signed off by an engineer. fitting HSV brakes is probably going to slip through the cracks but your fitting newer VE style brakes which have a completely different hub setup to the vz this will require an engineer cert.

Correct. Atleast someone in this thread gave a factual and correct answer.

Under SA Guidelines, any modification to the braking system needs an engineers certificate or to be apporoved by Transport SA.

Yeh it makes sence, but not always legal just like wider wheels give the car more grip, hence making it safer, but apparently its illegal.

thanxs monaro327 and dylan thats what i needed to know, so whats the best thing to do then? go hsv spec? or just slotted rotors neither of these will need an eng cert?

Depends what you're after I guess. The HSV spec can be a bit expensive, and slotted rotors might not give you the desired gain.

Its really only going to be an issue at Regency Park, normal Police will not pick you up for it and it is unlikely insurance will get picky enough to void anything because of it.

You could pay $500ish to get them engineered though

I have the same problem, as well as the fact that legal sized wheels don't fit over the brakes I have, so i'd have to get an engineers certificate for both the wheels and the brakes.

yeah man i think i will just go for slotted its about 300 ish for all 4 so that will be the way to go and the rest of the money will go to the 3.9s thanxs for the input mate, i look foward to seeing u sunday for cruise day m8

Hi guys, just wanted to chime in, as I thought someone might find this useful. What I did was get a Wilwood kit. Comes with 330 mm slotted discs up front (drilled are like $20 more), along with 6 piston calipers, and 315 mm (I think on the back), also slotted with 4 piston calipers. You need to order the brake lines separate.

Set me back around $3,500. Direct bolt on to a Chevy Lumina SS, which is basically a Commodore SS VZ or 2006 Pontiac GTO.

Are they worth it? Well, yes, they are more responsive. Do not fade and make me feel safer when I push the car in rush.

Another option would a StopTech front only kit. I think it comes with 6 piston calipers up front as well.

In retrospect, I would do the StopTech kit. Its like around $2,000 without shipping and I think would do just as well. Why? Well, I checked my pads the other day after 6 months of daily bashing. The fronts have worn more than than the rear.

thats because u do 90 % of ur braking on the front m8 rear just stablise the car, thanxs for the input but thats alot more than i got qouted so im just doin 4 slotted rotors that will improve a lot more and for 340 for 4 i cant go wrong really,

besides my insurence company wont cover me if i got to the ve spec [with is what i was gonna do 322mm]

[andyman]

hey archers, where abouts is this mob that you were getting the brakes off, im trying to source some brackets for them....ive seen them before, just carnt remember where, ive got some ve brakes lying around home

[monaro327]

Archers, i hope you realise by slapping big brakes on the front and leaving the back brakes stock you'll mostly increase stopping distances in an emergency.

Reason, ABS mate your fronts will lock up so easily compared to the back bringing the abs in much earlier. or so Harrop told me hence why they wont sell split kits of their monster line. a slight upgrade to the front is fine but 6 or 4 piston mono blocks and 350mm rotors with the stockers on the back will end up bad.
