Much better doing it yourself or getting it done properly by a auto fab place.
The guy that fabed mine said he has cars doing 4ft wheel stands 1000Hp with what i Had done and never any problems, also improves handling quite a bit 2.

The CRS LH-LX chassis kit is a bit different to the mod in the picture above.
From what I can see the mod above connects the lower trailing arm mount to the chassis rail which effectively reinforces the trailing arm mount. I can see that this would increase the bending strength of the vehicle but I can not see how it would increase the torsional strength.
The CRS LH-LX kit runs from the lower trailing arm, bolts to the chassis rail using the gearbox crossmember bolts, then bolts to the K-frame mount then about 300 mm up the chassis rail. It is then cross braced by the stronger gearbox crossmember (not shown). The CRS kit does not intrude into the rear seat footwell.

The upper and lower control arms mounts, where also fully strengthened as the top arms are in tension and can rip the floor out with big Hp.
So bending stress is like bending the vehicle about the centre?
and
torsional stress is like twisting the chassi??

Also is it worth putting a 4 Point Steel/Alloy roll cage into my LJ?
How much would you pay for one (I know there are some on Ebay).
Should I bolt/Weld it in. And the rear connection points seem to stop on the parcel shelf...is that strong enough?

I guess you could always extend a cage all the way to the boot floor...
On the note about the lower control arm "brace" (not the metal rods the good ones Rory is always raving about) - where can you get them? I've searched on Ebay to no avail, does the "guy" still make them or what?

There is another set of CRS chassis rails on Ebay at the moment. I made my own rods for the lower arms using 1/2 steel rod. The plate for the front crossmember can be made easily with a piece of 3mm flat plate.
I had not one ounce of trouble fitting my kit but then i bought it s/hand from Adam when he was over east so it had been run in per say.
Cheers,

Mine, hehe. I've already got the XU-1 reinforced lower control arms in mine but I wanted the crossmember to radius arm strengthening brackets as they crack badly on the radius arm at that junction. The only other piece missing from that front end kit is the plate that you weld over the bottom of the crossmember. I bought my body bracing and front end strengthening kit for $600 about 3.5 years ago. At the time I spoke to Rod Hadfield and he said the crossmember plate doesn't do anything at all strength wise, its purely cosmetic to cover up any marks from when the car has been jacked up and left impressions in the bottom of the crossmember in the past. I still have the delivery docket for the kit and all up it weighs 25kgs.More bits.

Yep, mine too. Was anyone from here bidding on it in the end? Jacked up the price on me. Its still cheaper than new from CRS and has some extras included too.There is another set of CRS chassis rails on Ebay at the moment.
