Yet I'll let you know how i go. Mite be a while tho. Also, Does ANYONE know whats the deal with the VS Reservoir on the VT Master? In the 1st post thats what the dude says to use but everyone says that it doesn't fit? Is there any other reservoir that'll fit on AND sit on the correct angle? Some original photos have not been recovered yet.

Parts? what parts? nothing yet but I will be needing VT master, VS V6 booster, and a reservoir. probly all of which i'll get from Advanced or something. AND I would prefer some line adapters too, so much easier. Emailed ENZED a few weeks ago, explaining i was after some adapters to convert VL lines to VT master, and they told me the VT flare (cant remember what it was called, single or ball flare or something) is illegal! WTF its a newer car????

yeh good luck finding the expensive adapters, it will work with the VT tank,i have a vs booster here if you want it,i thought the hassle of the adapters wasnt worth the money so i went to the wreckers,yeh it only cost $5 to change the flares,there are 5 to change front 4,rear 1,dont need custom hoses just use VT and bolt the bracket to the body near the old one

ohk well i've got the front custom hoses anyway so i don't need to worry about that. when changing the flares, who did you get to do that? and do the lines need to be taken out or do they do it on the car? is the booster working fine and is it a v6 one? how much do ya want for it?

WTF its a newer car???? VL is single flare VT is double flare. Different ADRs would make it illegal ie, if u put a single flare on a VT Quote: Originally Posted by markovr You have to be joking...never trust a single weld to keep it all secure....use jimbos page as a guide and you bend your old bracket and weld it to another flat fabricated bracket ...you could even use the 10mm bracket but this setup doesnt depend on one single weld for strength and uses the original studs and nuts for strength like it was designed.... any weld just keeps everything together so it bolts up......use this site http://users.bigpond.net.au/jimbo123/VN/ under mods as a guide. its for a vn but the setup is the same for previous models like a vl I'll just make a comment to save any ambiguity. markovr, mate i dont think you quite understand what I'm achieving here. I've had this checked with a mechanical engineer so there is no problem with the structual integrity with this mod. btw this "setup doesnt depend on a single weld for strength" there are a series of spot welds, which is wot holds your monocoque chasis together. that said theres probably nothing wrong with your mates mod either, im sure there are many ways it can be fitted, this is just my way. cheers

To help with the confusion why some of you can fit the master cylinder and others cant VT commodores came out with two (2) different master cylinders. Firstly the difference is one (1) is an ABS version the second is a NON-ABS version. The ABS version has two (2) fittings close to the front that go to the ABS module. The NON-ABS version is the one (1) that you need for this mod as it has the outlets like in the pictures. I hope this helps with some of the confusion.

Don't you mean the master cylinder (not the booster)? and wouldnt the ABS master have only 2 fittings (that go to the ABS module), and the Non-ABS have 3 fittings?
