Hi Guys,
I am thinking about a 50mm body lift on my 92 4 door Vitara. Graeme at Suzisports Springwood says "Don't do it, the floor pan cracks around the mounts." So what does everybody think? True or False?

lol soon as I read the title i knew youd been to one of the suzisports
if you do it properly and support the body at all the support points not jsut the ones with bolts through em like some companies sell there is no reason for it to crack
having said thet I have seen non bodylifted ones crack too so its a common thing for Suzukis, not jsut bodylifts
more of a concern is bodylifts are for bigger tires, there is lots of bits on the front end need beefing up before even thinking about bigger tires

Thanks Royce. I think the tyres will stay at 29 inch because to regear i need 5.83's which I understand are impossible to get. But I have a set of 29" Swampers waitng for me at Fourbys.
I got to decide if I am Body lifting the Rig before I copy your Rock Slider design... Did you use 50mm SHS? Is 3mm thick enough? Are the mounts made from 100mm x 5 mm flat iron? That was my guess based on your pics.

you shouldnt need it with that size tire, depending on rim offset
mine are 50 x 35 x 4mm RHS and maybe 65 x 4mm flat from memory

The key point is to add the other mounts without bolts as Royce points out. I will keep an eye on mine and see what happens ! I cant see it would make much difference if decent mounts are used. Still the same surface area supporting it.. Maybe even less of a body crack problem as the chassis is further away now and it could move a bit more with extra height in the mounts.. ?

Guys,
I asked the same question on Outer Limits here http://carl.outerlimits4x4.com/viewtopi ... 15#1126515 and it developed into a useful thread. From what I found out, I think a lot of lift blocks are 50-65mm in diameter. They need to be 80mm to avoid problems. So VitZook, how wide are yours?

Dicks are 65mm.

Picked up the body lift kit this afternoon from just_cruizin. See:
http://www.auszookers.com/index.php?nam ... pic&t=1164
I've updated my Rod's Rig thread with a pic of the Kit as I picked it up here:
http://www.auszookers.com/index.php?nam ... pic&t=1074
This kit looks fantastic, easilly the best I've seen on any forum. Can't wait to get it in!
The Outer Limits Thread listed above got a fair bit of interest so check it out as there is some good info and links to existing how to's
Greg tells me demand for his kit is so high, he's starting on another batch tomorrow so get in quick!

Fluffy,
PM Greg about the material he uses. I discussed this and he tells me the material is used for mounting truck bodies in the transport industry. He also had extensive discussions with Qld Transport and did some NATA testing for his Sierra blocks. The compressive strength is very high in relation to the floor pan weight and they are 80mm in diameter. Taking a stab in the dark of a body shell weighing 650kg, and assuming I remembered the maths correctly, the pressure is only about 3.2kg per square centimeter excluding the four extra 50mm dia blocks under the rear of the shell fro my LWB. Taking this additional support into accout, the pressure is only about 2.5kg per square centimetre.

Hey Fluffy,
If the guy at Qld transport says not to use a polymer ask him about the rubber mount under the block and which will fail first. Also ask him what happens if the block does fail (which it doesn't) what the crush tube will do to the mounts.
I use HDPE which is an engineering plastic designed for high compression situations, it is used in fire trucks and other aluminium bodied trucks to seperate the body and the chassis.
Rod is mistaken about getting the blocks tested, this I haven't done but it is the bolts that have been tested to a proof load of approximately 40kN or 4 tonnes.
Greg
