Unless there has been an amendment I havn't seen, It doesn't actually say anything in my older book about Ali brake fittings. Only specifies the type of tubing. But Clint will know for sure. I would be surprised if it was allowed as the chance of having the softer Ali flare seat get damaged or threads strip out whilst tightening the assembly would be greater. 

 

If its this type of Wilwood box with the open webbing they have a tendency to crack where I've marked the pic in blue. Have had to repair a bunch for stockcar guys and make reinforcing gussets. If the firewall flexes even a bit, it stresses the Ali webbing too much. I see that Wilwood has closed in that webbing section now with more material, so if you got a newer one it might be fine. Just gotta make sure the mounting is pretty rigid with those Ali ones

I’m also considering a switch to a reverse swing Pedalbox for multiple reasons.

will likely only use either a Tilton or Wilwood set up.

I would plan to make a cradle that the Pedalbox bolts to, this cradle will be bolted and stitch welded in.

what is the go with pedal ratio? I’ve never actually heard of that before, do they just want to ensure that they aren’t too touchy (very little pedal throw to lock up).

Is there a standard pre cert check-list available for owners? You know so when the car rocks up for cert your project doesn't end up straight in the design disaster thread. 

I know I'm in cert category with my commodore so now it runs I need to get onto making it legal. Anything that makes my life easier and the certifier's life less painful would be great.

My certifier suggested taking it for a wof, that way you get basic shit picked up on, plus as they knew me and are a proper garage they were pretty open about the things they would fail it on.

It covers a lot of that list and you dont have to worry about it failing cert on dumb shit that was easy to fix.

If you modify something, check the LVVTA handbook (free download on their site) to see what areas cover said modification. Make sure it complies. Rinse and repeat on everything. Since every car is modified differently, the checklist would be pages long and most wouldn't apply to your car so not going to happen.

Pedal box, thought i saw something in the thread previously but could find anything.

Pedal box in road car (rx3) are there any rules around how its mounted? What size material used etc?

And then bulkheads to get hardlines through the firewall do these need to be steel (presume alloy not ok?)

 

Not really any rules because every car is different , just has to be secure and fit for purpose. 

Most pedal boxes I've seen need mounting in 2 planes ie not just to the firewall, also needs to be tied in to the steering column mount/dash bar/ roll cage . Pretty much like most factory pedal boxes do

 

Steel or stainless only for bulkhead fittings

The brake chapter of the CCM is being updated soon so will have a lot more info in it

If you are using a Tilton or willwood pedal box you won't have to worry about pedal ratio. 

It's only a guide anyway not a *it must be this* thing. There's a lot of brake systems with pedal ratios outside of the manual that still work fine

I have had ideas of a database of different vehicles and their common issues/problems/things to look out for

Should figure out how to make an app or something I can make $ from

[shizzl]

Cheers Clint.

 

a “common fault” guide would be helpful to all parties.

i find the manual and absolute task to navigate at times

[Muncie]

@cletus have really appreciated the pointers on my build thread it's stopped me going off in to things that ultimately would of gone straight in to the bin....... like my bumper support that will now go onto the wall of shame.

@cletus interested on your option of this for brake setup, fitting z32 rear caliper to commodore diff, the aussies just cut and weld the plate to the backing (pretty sure not ok here)

so drawn up this bracket, would be 17mm thick with a 5mm step on one side (still 12mm thick)  to make mounting flush with existing backing plate for correct caliper to disc alignment. 

would need to cut back old mounting to red line and drill new holes would be threaded m10 same as factory caliper

 

Will also check in with my local certifier once I have fronts modeled and 3d printed mockups to test fit as well 

[cletus]

Yeah that looks ok to me 

 

You can actually weld brake caliper brackets if tig welded and passes ndt 

Your idea looks better though 

[vk327]

Cool thanks i like the bolt on idea myself, just wasnt sure on cutting the backing plate mostly, I could weld and NDT easily, we have NDT capability at work, could get it done when I'm doing my front coilovers

I spent last Sunday mucking around changing my flat deck to a wellside on my 99 Hilux S/C

The truck itself is an odd ball Jap only model, but I've found only 4 of the 8 tray mounts line up (the middle 4 are way off)

It looks easier enough to cut the middle 4 off and re weld them to suite, but will the wof man ping me for changing them?

Thanks in advance 

[igor]

Would the wof man even notice what you'd done if it was nice and neat?

[tortron]

Ute trays don't require cert, just normal no sharp bits, properly secured in service stuff

 

(Apparenlry if they are over 100mm wider than thr body they now need cert and pedestrian safety stuff, but that's not you)

 

 

*my tray is certed for some reason. Lol

[Bling]

Cutting them off the tray or the chassis? If tray I'd say all good, cutting off chassis probably worth avoiding. Custom trays are all the rage.

[hood]

Yes, moving the mounts on the chassis

 

 

[tortron]

Oh, thats different than modding the tray

[Bling]

I'd leave chassis as is and make the tray mounts work to what's there if possible. Modifying the chassis is quite different to modifying the tray which is just an accessory slapped on.

[hood]

Right I see, thanks for the advice team
