2 i have seen some wheels they are mini lights 15in and 5half inch wide . What size rubber do i put on im looking to drop my van about 4 to 5 inch .
thanks for the help

 

It depends how low you want to go.
Rule of thumb, the lower you go, the more it costs.

 

so if i want a 4 inch drop which way would be best to go

 

I think dropped spindles personally as it's too much for the standard ball joints going so low on adjusters.
You'll need to beef up the springs with coil-overs - earlybay is a good place to read of peoples experiences as they nearly all lower their vans.
At the rear adjustable springplates so you can get the wheel off.
