installing a bucket seat

Issues:

1 the seat must be ADR certified

2 the seat mountings must be engineer certified if a direct replacement to anchor to the in-body factory attachment points are not available from the seat manufacturer

a harness (3/4/5/6) point for street driving

Issues:

1 the seat belts must be ADR certified

2 the anchorages must be in accordance with the National Code of Practice for Light Vehicle Construction and Modification (NCOP)

see:

http://www.dotars.gov.au/transport/safety/...n/vsb_ncop.aspx

do the back seats need to come out

If the seatbelt enters the safety areas specified in NCOP then that seat position must be removed.

More importantly, removing the seat isn't the end of it - the vehicle must be re-certified with an appropriately reduced seating capacity.

So, no you can't just pull the rear seat out, bolt in any old seat and throw in a harness.

A way around it:

Use ADR certified seat belts and install a completely additional set of belt mounts.

Get those certified, together with the seat mountings.

When using the harnesses, remove the rear seat entirely and fit a neat carpeted panel in place of it.

Carry the standard belts all nicely packaged in plastic together with a copy of the certification documentation and the official approval papers (Dept of Transport etc).

If queried explain politely that the car normally has standard belts and rear seat but for specific occasions these are changed for the alternates.

We do this with our 240K GT for navigational rallies etc and Transport SA was satisfied that it was geniune and reasonable to do so.

btw, there is NO point in a beaut seat and flash harnesses if you don't invest in a roll bar with appropriate rear braces. Again, see NCOP

thanks heaps for your goldmine of information mate:D much appreciated,

but let me just get a few things straight, firstly, i can have a seat installed and harnesses fitted so long as they don't interfere with the normal set of belts, so i have both sets installed and able to be used at once, i just select which i use? and the seat must either fit the standard factory ones, or i can run other rails so long as they are engineer certified?

and when using the harnesses, remove the back seat and put carpet over the top, and if i am queried explain whats gone on and it's sweet? or can the back seat remain there at all times, even when using the harness's?

Cheers again mate, Dave

i can have a seat installed and harnesses fitted so long as they don't interfere with the normal set of belts, so i have both sets installed and able to be used at once, i just select which i use?

Get confirmation from your State's DOT (preferably in writing).

I have been advised (DOT SA) only one set of belts can be installed even though the correct anchorages for the others are there.

the seat must either fit the standard factory ones, or i can run other rails so long as they are engineer certified?

The seat isn't the issue, the rails & mounts are.

So, either

1 rails from the seat manufacturer to bolt to the stock in-body mounts (they will have already certified that combination to be ADR compliant) or

2 rails from the seat manufacturer with new body mounts that then must be engineer certified and accepted/approved by your DOT.

That may be as simple as decent adaptors between the rails and the original in-body mounts.

when using the harnesses, remove the back seat and put carpet over the top, and if i am queried explain whats gone on and it's sweet? or can the back seat remain there at all times, even when using the harness's?

The back seat must still come out and you will usually find that the average police officer will look favourably on a 'responsible' attitude. If he reckons you are genuine in trying to prevent injury to others he can be remarkably understanding.

Alternatively, talk to someone in your DOT.

You may find they will issue a modification approval which actually covers the two alternatives (harnesses / no rear seat OR lap sash / rear seat) or else a letter confirming that when the harnesses are installed then the rear seat must not be.

That alsp implies that they realise that it is not a permanent alteration.

    • The engine stuff is Greg Autism to the Max. I contacted Tony Mamo previously from AFR who went off to make his own company to further refine AFR heads. He is a wizard in US LS world. Pretty much the best person on earth who will sell you things he's done weird wizard magic to. The cam spec is not too different. I have a 232/234 .600/603 lift, 114LSA cam currently. The new one is 227/233 .638 .634. The 1.8 ratio roller rockers will effectively push this cam into the ~.670 range. These also get Mamo'ified to be drilled out and tapped to use a 10mm bolt over an 8mm for better stability. This is what lead to the cam being specced. The plan is to run it to 6800. (6600 currently). The Johnson lifters are to maintain proper lift at heavy use which is something the LS7's supposedly fail at and lose a bit of pressure, robbing you of lift at higher RPM. Hollow stem valves for better, well everything, Valve train control. I dunno. Hollow is better. The valves are also not on a standard valve angle. Compression ratio is going from 10.6 to 11.3. The cam is smaller, but also not really... The cam was specced when I generated a chart where I counted the frames of a lap video I had and noted how much of the time in % I spent at what RPM while on track at Sandown. The current cam/heads are a bit mismatched, the standard LS1 heads are the restriction to power, which is why everyone CNC's them to get a pretty solid improvement. Most of the difference between LS1->LS2->LS3 is really just better stock heads. The current cam is falling over about 600rpm earlier than it 'should' given the rest of my current setup. CNC'ing heads closes the gap with regards to heads. Aftermarket heads eliminate the gap and go further. The MMS heads go even further than that, and the heads I have in the box could quite easily be bolted to a 7.0 427ci or 454 and not be any restriction at all. Tony Mamo previously worked with AFR, designed new heads from scratch then eventually founded his own business. There he takes the AFR items and performs further wizardry, CNC'ing them and then manually porting the result. He also ports the FAST102 composite manifold: Before and after There's also an improved racing crank scraper and windage tray. Helps to keep oil in the pan. Supposedly gains 2% power. Tony also ports Melling oil pumps, so you get more oil pressure down low at idle, and the same as what you want up top thanks to a suitable relief spring. There's also the timing chain kit with a Torrington bearing to make sure the cam doesn't have any thrust. Yes I'll post a before and after when it all eventually goes together. It'll probably make 2kw more than a setup that would be $15,000 cheaper :p
    • Because the cars wheels are on blocks, you slide under the car.   Pretty much all the bolts you touched should have been put in, but not fully torque up.   Back them off a turn or two, and then tighten them up from under the car with the wheels sitting on the blocks holding car up in the air.
    • Yes. Imagine you have the car on the ground, and you mine away all the ground under and around it, except for the area directly under each individual wheel. That's exactly how it'd look, except the ground will be what ever you make the bit under each wheel from
    • Yes, if you set the "height" right so that it's basically where it would be when sitting on the wheel. It's actually exactly how I tighten bolts that need to be done that way. However....urethane bushes do NOT need to be done that way. The bush slides on both the inner and outer. It's only rubber bushes that are bonded to the outer that need to be clamped to the crush tube in the "home" position. And my car is so full of sphericals now that I have very few that I need to do properly and I sometimes forget and have to go back and fix it afterwards!
