New E70 owner couple of questions

[hp99hp]

Hey everyone! Been a while since I posted on here. Anyways we previously had purchased a 2005 4.4 X5 with a 4.8 conversion. We traded her in yesterday for a 2008 4.8 with the following options:

• ACTIVE VENTILATED SEAT PKG
• PREMIUM PKG
• PREMIUM SOUND PKG
• REAR CLIMATE PKG
• SPORT PKG
• TECHNOLOGY PKG
• 20" Y-SPOKE ALLOY WHEELS
• RUNNING BOARDS (328)
• DARK BAMBOO INTERIOR WOOD TRIM (4AZ)
• 3RD ROW SEAT
• 20-WAY PWR MULTI-CONTOUR FRONT SEATS W/LUMBAR (456)
• 3-STAGE HEATED FRONT SEATS
• REAR SEAT ENTERTAINMENT SYSTEM
• HIGH-DEFINITION RADIO (653)

Now I'm looking into getting some H&R springs for the car, but my question is how can I figure out if I have self leveling or not? Sorry for the noob question. Secondly I want to put spacers to push the wheels out to sit more flush with the fender line. Does anyone know what spacers I'll need in the front and back to accomplish this? Thanks in advance for the help!

i wouldn't do it. if anything i'm thinking you will hurt the handling more than enhance it.

the '08 4.8 with sport is a fine vehicle in stock form IMO.

You have 3rd row seat, so you should, by default, have self leveling suspension.

Don't lower it. You will destroy the ride quality as the X5 will be permanently riding on the bump stops. I know it is tempting to reduce the fender/wheel gap but you will regret it.
The 20's fit fairly flush as is. i would leave the front and maybe do 12mm in the rear. Make sure you get the longer bolts in the X5 diameter if you do (they are not the same as used on other BMW's and are kind of tricky to find).
