johnson is right,

get your wheel and tire combination first and then look at your control arm lenghts.

however, you want to keep an eye on scrub radius, which is the distance from center of the tire to the line drawn from the upper balljoint through the lower onto the ground.

keep it as small as possible, but you will realise soon that it won't happen if you use a wheel with a decent backspacing to make it look right.

play with the KPI (king pin inclinateion) to get some improvement, but don't go overboard with the angle. 5 degrees is good, 10 possible, but preferably 5 to 7.

the 427's is 2 5/8".

cheers,
