I'm trying to find out whats the right hight for the road wheels to be at on this kit. for any example is this the correct hight, or dose it need to be lower or higher than its currently at??

it might be just a little bit higher...
I lined them up with the line on the hull and placed them just a fraction higher then.. as could be seen in this pic;



You could also dry-fit the side armour, they need to be behind it just alittle bit...





hth

Thanks for your Help on that.
