Harnesses

[neil_se]

I've just been reading the ANDRA Sport Compact rule book (Section 10.11, p83) and it says that a 4 point harness must be used on "Sedans quicker than 11.99 (1/4mile) ... or quicker than 110mph (176kph)."

I get lost as to which class my car qualifies as, so does this rule apply to me? I hope to run a mid to high 12 which i think would be just over 110mph.

cheers

Neil

Anyone?

its reads to me, that if you want to run over 110mph (which you say you will) you will need a harness. although ive seen many cars that run that quick without harnesses, but it may just be a rule for sport compact.

:confused:

That's what i thought. I might be off on my predicted trap speed, but i don't want to turn up, do a couple of runs then not be able to run again. I was sure there was lots of other cars here running faster than that and never seen a harness.

If you'r smart you'll be using at least a 4point harness whether the rules demand it or not

[neil_se]

Not the definate answer i was looking for. We've booked out Willowbank in August, i don't want to turn up without a harness and find i'm not allowed to do my other 20 runs. Money is an issue, otherwise i'd definately get one now.

mate I've ran countless runs at well over 120mph in Sydney with out a harness, I think you should be fine

If you do need to fit one, non FIA approved 4 point harnesses are pretty cheap, about $200. If ANDRA require FIA approval that will double the price

Isn't the guy from ANDRA on here somewhere? maybe pm him

[neil_se]

Cheers guys, that's what i thought. I'll shoot ANDRA an inquiry in a min.

I you need to get one..... get the type whereby the 2 front mounting bolts replace the existing bolts for your 3 point. They are a ringbolt and you can retain your 3point harness and the 4 point clips on over the top. you canmount the rears on the parcel shelf with reinforcing plates under. If you'r that short of cash....just put in the mounting bolts and i'll lend you a harness

[neil_se]

Thanks for the offer Jay, i'll see what i can find out and let you know. The installation was the cost that was worrying me a bit but if you can replace a couple of the standard bolts that would be much easier. Any idea how much will an ANDRA-approved 4pt harness costs?

Got mine fromWholesale Suspensions at Slacks Creek, think it was about $190. It has spring hook at it's attachment points and just clips onto the replacement ringbolts, so can be easily removed

[neil_se]

That's a better price than i thought. Probably something i should be asking a workshop, but do you know where options for the rear points to be mounted are? I've got a rear strut brace that would be perfect to use when the back seats are down.

Ideally the rears should be set so that the angle of the belts stretching back from your shoulders to the rear mount points is no more than 10 degres from horizontal but up to 45 degrees is acceptable. The biger the angle ...the less effective the restraint
