Well 6200 is the limit now, raising it to 7000 would be nice, I doubt I'd want to go past 7500 though, don't want to risk anything. I think the FTE rods would be the easiest option, assuming they're the same height as the FE ones. All of this is a long way off though, it probably wont be until next year when I get serious about modding the 4EFE, but learning is the only way forward. Either that, or get someone else to do it, which takes all the fun away.
