just finished having a go at this on mine as the stock suspension was shagged (160k miles and i suspect they've never been changed before). rear is looking good but the front is a fair bit higher than i anticipated.
measuring from the floor to the bottom of the doors im about 1 1/2" high at the front. i think this is partly because i used mk3 legacy front shocks (kyb-334167). i had to turn up a 1/4" thick shim to fit the mk3 shock into the mk4 mount/bearing (the bearing of the mk4 mount is thinner so the threads dont reach), i put the shim inbetween the spring seat and the mount and in hindsight i could actually move it on top of the mount, inbetween the mount and the nut which will give me 1/4" drop in the front.
hopefully the front will settle down a bit more than the rear so with the 1/4" drop in the front + a 1" spacer in the back i'll be happy =]
i think my rear is also sitting a bit lower than most would as theres about 250lb of propane/tank in the spare wheel well and the springs were the cheapest rubbish i could find lol.
also riding the rear bump stops a bit to much atm, still waiting on some leggy bump stops and rear upper arms + whiteline rear camber bushings to come in the post =]
dat front camber tho :S off for an alignment i go
