Im looking at taking my car out to the track. right now i am performing the neccessary upgrades to ensure i can race.

I saw that i need to have a secondary bonnet restraint. What do you guys use?

I have a standard bonnet and i think i will look like a wanker if i put bonnet pins on it. Anyone got other suggestions?

Cheers

Does it state that its needed for a stock bonnet?

The OEM latch is unlikely to fail, and if it does, the safety catch is also unlikely to fail.. if you see it quick enough.

I wouldnt be worried about a secondary catch for an OEM bonnet. Unless it clearly states it IS required for an OEM bonnet too.

Iv been track racing for years, and the only people i know with pins are those with CF bonnets where the catch isnt bolted to anything structural, IE the fiberglass skeleton.

Also, out of the many many many days i have been to i have NEVER ever seen a bonnet come unlatched or fly open.

The odd muffler fall out the ass, fuel tank straps coming off and blown motors/boxes, even an engine mount bolt working loose and flying out under the car... :D but never a bonnet!

I've seen many carbon fibre bonnets come off actually. It's really hilarious to watch (not for the owner of the car though).

They often smash backwards and smash the roof and the windscreen. Sometimes they crack badly and bits of the bonnet flies off.

Most of the track days ive scrutineered, a secondary bonnet restraint is necessary. Lots of people hook an old belt from the bonnet frame and clip it down through the bumper or so. Another way is with a small chain and a shackle/caribbina and hook it onto the radiator support.

basically it depends on the Supplementary regulations for the event you are entering. If the Supp regs dont say anything you don't need a secondary restraint unless it is full on racing (schedule C requires secondary restraints for non road regstered cars)

Most events dont need a secondary restraint for modern cars

1 question though,

With using a belt or the clips etc, what if theres a fire under the bonnet?

Be a bit hard to get them undone in time?

mind you though if there is a fire Id be out quick smart! but if a small,little fire started?

Despite the dual catch system std on modern cars the track days we do with the WRX club here in Vic state you need one. There are lots of ways you can do this.....bonnent pins are fine with a std bonnent, others use a belt strap fitted to a suitable spot and I use a wire cable attached to the frame of my bonnent which hooks to the radiator support.

my advice is buy one of these babies. http://www.initialdrift.com.au/forums/view...074&start=0

cost about $25 and make sure you ask for it to be sheathed with the rubber heatshrink (stops it scratching up stuff). easy to fit, just need to drill a hole.

now that I've bought mine I just keep it in my helmet bag with licence and helmet etc so that I never forget to take it to a track day/sprint/whatever.

I'm surprised you need a secondary restraint for a skyline, its certainly not required in the CAMS regs (late model cars don't need an additional restraint). Unless it is requried by the supplementary regulations, I haven't seen them

Yeah some events now are starting to require them now even for late model cars. Up till now later model cars with an un-modified 2 stage factory catch have been ok, but for some reason of late it seems they are moving towards making all cars use a secondary restraint. Even a recent drift day I attended required all cars to have one and that is classed as a non-speed event!

Still for $25 and 5 mins drilling a hole it's not too onerous. :P

      After market rear camber arm adjustment

      By Duncan · Posted

      Then, shorten them by 1cm, drop the car back down and have a visual look (or even better, use a spirit level across the wheel to see if you have less camber than before. You still want something like 1.5 for road use. Alternatively, if you have adjustable rear ride height (I assume you do if you have extreme camber wear), raise the suspension back to standard height until you can get it all aligned properly. Finally, keep in mind that wear on the inside of the tyre can be for incorrect toe, not just camber

      I know I have to get a wheel alignment but until then I just need to bring the rear tyres in a bit they're wearing to the belt on the inside and brand new on the outside edge. I did shorten the arms a bit but got it wrong now after a few klms the Slip and VDC lights come on. I'd just like to get it to a point where I can drive for another week or two before getting an alignment. I've had to pay a lot of other stuff recently so doing it myself is my only option

      You just need a wheel alignment after, so just set them to the same as current and drive to the shop. As there are 2 upper links it may also be worth adding adjustable upper front links at the same time; these reduce bump steer when you move the camber (note that setting those correctly takes a lot longer as you have to recheck the camber at each length of the toe arm, through a range of movement, so you could just ignore that unless the handling becomes unpredictable)

      I got adjustable after market rear camber arm to replace the stock one's because got sick of having to buy new rear tyres every few months. Can anyone please let me know what the best adjustment length would be. I don't have the old ones anymore to get measurements. I'm guessing the stock measurement minus a few mm would do it. Please any help on replacing them would be fantastic I've watched the YouTube clips but no-one talks about how long to set the camber arm to.

      Heh. I copied the link to the video direct, instead of the thread I mentioned. But the video is the main value content anyway. Otherwise, yes, in Europe, surely you'd be expected to buy local. Being whichever flavour of Michelin, Continental or Pirelli suits your usage model.
