i have roh 16 by 6's chicane wheels on mine with 205 45s before that i had 14inch hustlers with big 255s on the rear ,i found the floor is a complete p#$k of a thing to clear and had to carefully modify had with a bloody big hammer to make them fit, also as you pointed out the front of the guard does need cutting and rolling to clear, the tops of the guards will need to be pulled out to clear other wise when you are pulling up fast or hit a big bump they will hit even with reeaally heavy springs, mine took alot of panel beating because i like having my wheels neatly tucked level with the guards, also good sway bars (front and rear) do help alot here because the car swats instead of leans ,and also handles better . with all of that and extra leaves i can sqeeze 5 big people two huge motherf@#$ng alpine v12s three 15inch subs and the weight if the rollcage and the wheels still only scrape a tad on the floor going over steep gutters on wierd angles. ps i have sunny front stuts with a little extra camber. pps our roads suck . ppps.sorry i ramble on to much
