I ran 35's for years with my 90 IFS and 3" body lift. Chopped some fender up front. It wore out the idler arm and I've had to do CV boots. I'd guess that stuff goes after 14 years anyhow though. Switched to 4.88's about 2 months ago from the 4.10s and its very nice on the highway and in the mud too. Around town on 33's it's a big differance for the better. I use 36's off in the mud and it's a nice combo. Theres not much to flex on in FL so it just about never hits fender and works fine for mud/water from what I've done. Just make sure you get the right offset for your wheels or 35's will put a nice polish on your swaybar when you turn. As far as strength from the IFS parts, I've had no real problems. Go for it.
