full tubs means moving the rails in so bigger tubs can be fitted ( this being only registerable as individualy constructed!
ie: a pain in the ass)
mini tubs means widening the tubs to the rails ( this being registerable as modified production!)
It was mentioned of moving the springs inward, this could be done with consultation with an engineer, to make sure the new spring mounting locations meet satisfactory standards.( one thing to remember when moving the springs in, is that by doing this you will be raising the roll centre of gravity. this being another thing to disscuss with the engineer.)

As for buying or making the mini tubs a simple way is to mark the centre of the original tubs from front to back cut this line and un pick the inner part of the tubs. move this in the required amount ( on a 1200 ute it is less than an inch before you hit the rail ) then weld a strip the same width of this movement into the centre section.

Sorry blokes, i'm trying to figure out how to place a photo here. [I'm not succeding]

"Screw-doctor-spock" [fat bloke with orange shirt] seems to have summed it up perfectly, except for the part where i think they look silly.

Wide wheels should come out to the edge of the body as near as practicable, but those tub jobs with more clearance between the tyre & the edge of the wheel arch than a stocker give all the "appearance" of a badly thought out design.
Well thats my highly biased & thoroughly biggoted opinion.

oi, i think my flares make my car look tuff as especially cause the tyres fill them up nicely, and the stance helps handeling (not the point here i know)

but i still reckon flares is the way to go, and my 12 sec a15ett will be running flares!

i agree to disagree...

p.s. what you talking bout getting car engineered with tyres sticking out, its perfectly legal not engineered, if it wasnt my car wouldnt be on the road, that bitch of a copper wasbusting to find a third thing to defect me on so i had to get roadworthy, but luckily for me she wasnt that bright admitadely

That was my plan dvldat but it is much easier to buy the mini tubs as there is someone out there that makes them. so all you have to do is cut the width to suit and weld them in. i have a mazdea bravo diff that wasn't shortened to fit and was just going to get a front wheel drive offset ti tuck it under the guards but the spring is the way. you need to have an engineer to submit drawings to the dept of transport to move your springs

agree with madtimo
dont get flares on your ute they lok awfull..
all u need is 2 get a hilux diff get it shortened and relocate your leaf sprig set up in ward about 4 '' and new set of wheel arches as (TUFFAZ) yellow ute has done.. very neat and alt more traction and still can driev around corners on boost and not have 2 worry..

1200rc, I think the main reason people mini-tub is to keep the wheels inside the guards, as there is no way a car is will get engineered with the wheels sticking 2 inches outside the guards.

...plus it looks AWFUL!!!!

That'd be my reasons for mini-tubbing anyway...

Dodgeman you seem to alot about cars and your questions and anzwers are always interesting to read. I am not trying to be rude but have you only ever seen fully tubbed cars in pictures with like 15z10inch wheels under them??? That is solely for drag racing as they don't turn corners. Mini tubbing is moving the spring over a couple of inches to fit wider wheels with a different offset.

At the very great risk of being buried in even more vitriole, tubbed cars look stoopid. It was originally done for a number of practical reasons on the drag strip.
Those reasons do not translate to the street where cars normally go round corners while being driven.
If the rear axle is narrowed enough, the wheel track is easily reduced beyond legal specs & even the averall measurement from the outside of the tyres can easily be less than stock. For street use, thats just plain dumb. No personall offense intended, but i wish people would

Thank you for your input. I have spoken to Peter at widowmaker and he said that we will be able to work something out. I will have trouble with the adding weight idea as i have a wider track because of diff choice and i already scrub with a little weight in the back. Flares on a ute don't look good as i tried on my old 1000 ute. I might see if i can get the rear guards lipped and pumped out a bit and try the weight adding first. I like having the wheels inside and under the guards. The ute does have a light blue tinge to it. it is a piece of #### but goes hard!

Mini tubs and tubbing developed as a result of the drag racing classes requiring that bodywork remained standard looking ..no flares. Aerodynamic efficiency is also a factor in the super quick pro stock classes. Tubbing has become popular as a "look" as well. I find it a little amusing seeing cars cars built to the "look" with massive rubber at the back and skinny 3" wide frontrunners squealing around the local cruise spots..I like the look too but I'd rather have a toy that was comfortable to drive and went round corners as well as it did down a strip..
