33" tyres, anything more?

4.56 would be my option. the trans behind the 4.0's arnt the beefiest so a lower axle ratio will help preserve it.

thanks for the help now my final question, where can i purchase the 4,56's ? any well known webshop that has alot of parts for our cars?

any regular rotation dana 35 front set should work and all ford 8.8 sets are the same.

Search Randy's Ring and Pinion.

I think it's just www.ringpinion.com

They offer a ton of different options, from ultra cheap (don't buy these) to expensive, race-ready options.

by the way, I have some kind of air suspension system, air springs.

Will that be any problem when mounting the pa883 bodykit? warrior shackles, add-a-leaf and tt?
