kaymar & 35's

Also, in the case of the Opposite Lock version at least, the 35s would be too wide and you wouldn't be about to close the 2nd swing-out wheel as it would foul the 1st one that was already closed. 33" (or 285/75R16) are okay AFAIK.

Sorry, don't know about the Kaymar at all

Okay Roachie,
I stand corrected.

Nope I just double checked it and you can fit two 35" tyres on a 100s if yous close them both at the same time.
It's a tight fit but it works. There is an article in 4Wd Monthly edition #79 May 05.

Bloke in our club who is in the Willem guize of going where no man has been in 40 yrs, snapped both his chassis rails clean in 1/2, (think awill has seen this car too) right over the rear diff..

His car weighs the same as roachies, (3300 before packing anything, weighed after having chassis repairs, and laminated chassis),

Trev puts it down to is 2x315's on his Kaymar bar. Hes gettin rid of it ASAP, and doing something else.

All that weight bouncing like a hinge off the back, something had to give, and it did!

How much heavier are 2 x 315s than 2 x 265s?

Truckster has me worried now......although I've always been aware that the rear spring towers on the GU are a potentially weak point. I've never heard of the chassis cracking.

If mine ever does crack or some other drama with rear chassis/spring hangers etc, I've already decided that will be the perfect time to get the back chopped off for a cut and shut with a enclosed (dust proof) box to store all the gear (may even get the lazy axle fitted too). But I'm not wishing it on myself......lots of bucks!!!

Roachie...
the weight difference depends on brands and models... IMHO, for what your doing, dont bother with 315's, I know you love to just spend money, but unless your crawling, which you arent 315s would be a waste.

Trev is actually gettin rid of the whole bar and all, he had already had the chassis crack once and had it laminated.

dont believe everything you read....
one of the comp dudes in melb has spoken with an engineer, and he is getting his GU comp truck engineered with 37's.....

Havn't just read it; got it straight from the horse's mouth last week; one of the state engineers working on NCOP direct. Absolutelly ruled out anything above 33"s from when it starts (maybe Dec 06). Of course the difficulty for them is retro-spective enforcement. If I were doing anything serious, I'd be doing it now, getting it certified and getting the mods noted on my rego papers.

Engineers are also getting a bit more nervous about some of the mods that they are certifying, and they are finding it more and more difficult in getting insurance for the work they do. The new regs have to be communicated to engineers and understood, and I reckon the authorities are going to have a hard time getting the enforcement right; with the way states are taking money out of the public service, they won't be employing more inspectors,

Dec 06... so it doesnt really mean crap yet does it? so you can engineer 35's or what ever the engineer will go with still....

That's right - do it now!
