Yeah, you'll have to do a little fender trimming to fit 33s or 34s on it. Does the RUF move your axle forward at all? I can't remember.
You will love the 6.5:1 kit, are you going with TG or calmini?
With 33s or 34s, the 6.5:1s are about perfect, so long as your engine still has some pep. You could go a little lower in the diffs, maybe sidekick auto gears, which are 4.30:1 (or somewhere near there) or the manual 5.13:1s. But with the auto r&p, you should have full use of 5th gear back, on 34s, with a stock 1.3l.
