Outer Limits 4x4 Board

OK chasing info & got some from another forum...LCOOL
Have a 2006 79 Series 4.2TD & was mentioned by someone who knows that 1 inch spacers on the rear would be worth while..

So who has em or knows about them & can give me some feedback before i do it??
I understand it illegal but we all got shit lke that on our trucks, bearing wearing might be an issue & whel studs might be weakenned apparently..

Cheers for the help..

i wouldnt waste my time

the front track is 1475mm
and the rear 1460mm,

maybe on the v8 76,78 and 79 series were the front track is 1555mm and the rear is 1460mm
