Demo,
Hey, your ride looks wicked with those rims...that's the kind of rim I was looking for, except in silver...nice!
I have the Illuminas with the MeGaN springs. I have since changed my wheels but I previously had, on the car, (P5) a set of 17X7 rims with the 42 mm offset and they rubbed the rear right fender like crazy. The left rear only when heavily loaded. I had to roll my fenders to keep that from happening...even with the MeGaN and Illuminas.
I'm not going to lie to you, this setup is quite a bit stiffer and doesn't lower the ride too much but even then, with a fully loaded car, the rear wheels tuck and, had I not rolled the fenders, they would rub.
The recommended offset for a wheel width of 8" is 48mm or more. There is a post somewhere "Rishi's fitment guide" or something of the sort; you could get the same answer there if our 'warnings' don't...uhmmn...make sense.
No matter what suspension you get, with the exception of a super stiff, full racing set-up, the tires will tuck and rub unless you exchange the wheels or do some serious rolling. If you're going to do the rolling bit, I'd recommend taking it to a shop to have them do it professionally.
I did the fender rolling myself and I don't think you'll be able to get the amount of rolling needed with my method...a bat. I've included a couple of photos so you can see what the car looked like with the 42mm 17X7's and rolled fenders.
As you can see on the photos of the car with the rooftop box and the bikes, th car is not much lower than without all that stuff. I also had my two toddlers and a hat-full of camping stuff.
