Yes.  Now I need to get some welding skills.

Wow, what a thread, all the answers....just time, skill and a scrap yard job are missing now...

Yeah, I should contact the guy & see what he says about an engineer's certificate

A mechanic was showing off his Toyota Tercel sedan that he put 15 inch rims on to me (not even low profile tires).    The increased ground clearance was almost shocking.  I wish I could remember exactly what he said he did with the shocks to fit those monsters in.  Him and I couldn't see that the All-trac would be any different.  For amusement we put 16 inch rims on my All-trac.  If it weren't for the bolts being to short, they might actually work with very thin tires.
He seemed to think that going with 14 inch rims is pointless when you can get 15's in!  I agree with other posters, that the best way to increase ground clearance is to use bigger tires.  

A trip to the auto wrecker to find some rims may be in order.  I know he would delight in getting them to work for me.

The only problem with bigger tires is maintaining the same total rolling circumference. Meaning the tire has to turn the same # of times as the old tires, because that is what you're speedometer is set for. Otherwise you're going to have drastically different speedo and odometer readings.

Another thing: Heavier wheels are harder for your engine to turn, producing a lot more load on the car.

Oh one more: Your steering rack's torque gears are designed to move only a certain amount of rubber on the ground.

I had 15's on with the same rolling circumference as my 13's (they were low profile), and I noticed a difference in steering, braking, and the lack of torque in the low gears when accelerating.

So yeah you can gain an inch or two, but at what cost? Thats my opinion. I'm running 13" winter tires right now, and when summer comes around I intend on getting 14's (NO BIGGER FOR ME AGAIN).

I'm considering getting a nice set of 15s for my del Sol, and then putting the del Sol's 14" rims on my wagon.  Same bolt pattern, I'm only unsure of the offset.  I know the del Sol's rims fit on the wagon as I've already test-fit them... just haven't test-driven the del Sol rims on the wagon.

Mate my car is lowered bout 4 inches and it sits on 15's could go 16's if i wanted and still would have room

it has kyb shock's and kings all round

and btw you could just get kings or another company to make some custom springs to any hight

then find out what shocks you want to fit

Why not just get air shocks?

Why not just get air shocks?

coz it's a lot of work

Yeah I was looking at the canisters in the back seat and all the air lines around Kebin's vehicle. A lot of work and it consumes a LOT of space!

I think some of it could be mounted on the outside if it was powder coated and the ride level was raised 4-8 inches! =D I'll know in a couple years when I can afford to find out!

the only wasted space my setup takes is the rear passenger foot wells. But anyway who carries passengers in the back? my seats are folded down all the time thus creating the Toyota shagging wagon!

See.. that's why you need more powerful engine  LOL  

I've picked up some rear air shocks that have a little car valve to raise and lower them. Will have to wait till I get back to install them though. Like you Jez - I want to exploit the functionality so I can still go down dirt tracks and through the snow. thinner tyres seem better on snow and ice as well. I've often got people in the back of my car and these shocks only cost about $60.00 NOS on ebay.

Are they the poly - air ones that fit inside the coil springs???

Could you take some installation pic's DownUnder?

I'm sure everyone would be interested to see how you go & what sort of results are achievable...
