Wow. That's different. Rally on brother!

All I see from watching TV, is scary Euro events hanging it out there, in a full cage Subar-something, going nutty fast, sideways on mud or slime, usually ending up in a fiery crash roll-over. Looks great.

Unless you're doing serious rally events, 17x7 to 17x8 wheels would do fine. if you're running in gravel you can run 225-235 wheels; snow, you would need something around 215-225 wheels.

You will want to run a slightly bigger sidewall than recommended, it will throw your RPMs off a bit, but will be better for the gravel terrain.

I would find gravel springs that fit your stock struts. I forgot the name, but it's like something-king springs. Not sure if they have them for the e46 though... You could probably pull springs from a X3 or something, if they fit onto your struts. you're going to want to raise the car at least an inch for rally cross; if you want to be fast through the courses.

I'd run the stock sways for now, since you will need MORE wheel travel on gravel courses; or really, any rally course. See how they handle, and adjust from there. Might just keep the stock sway and pull the rear sway off; won't know until you get out there.

coming from an STI background... and a HUGE rally fan Ask any question, I'll do my best to help.

rally-crossing an e46 seems like a terrible idea *shrug*

Why?

People rally cross brand new WRX's and STIs (ranging from 28k-38k OTD). E46 xi, if anything, would be the budget AWD vehicle to use, since they are well balanced and quite inexpensive.

Rallyx isn't really too extreme, terrain is quite flat, for the most part (in compared to profesional rally courses). it would be different if he was doing stage rallies... then he will definitely need to do a bit more than wheels, tires and suspension.

xi front axles and diffs can't quite take the repetitive abuse of grocery-getting, not sure how they will handle the abuse of constant loose terrain at speed. I'm sure the vehicle would be plenty fun, but I'm not convinced of how well it'd would cope.

Well... that sucks for that AWD drivetrain, maybe a sway of a certain parts will make it a bit stronger under those conditions.

Hopefully, for his sake, they do hold up!

You can definitely rallyX an xi!

Probably want to keep the stock springs, and get some bilstein HD struts/shocks, powerflex fcabs/rtabs, strut tower bar, schroth harness, and some better brake pads. Definitely reinforce the rear shock mounts, possibly with a shock tower brace.

I have an old set of studded nokian hakkapeliittas in 205/55/16 that do really well on dirt roads and loose gravel.

Also, I think a manual tranny is a must.

^^^ Manual is a must...

You can always run inexpensive snow tires and just throw them on backwards to grab the gravel better.
