Yep... I think the rear is already slightly higher with the stock wheel/suspension setup so raising it more might not be good.

Ok What problems will I run into if I ran 245/35/19 front and 285/35/19 rear? Will the cars electronics freak out?

With this setup the fronts will have a diameter of 25.75" and the rear will have a diameter of 26.85" difference of 1.1"

Will this freak out DSC or set off the FTM monitor?

Also where is the speedometer / odometer read from? front wheels or rear wheels? or is it averaged out through DSC?

What I'm afraid is that the FTM will go off like mad...

My DSC freaked out when I used 255/40/19 rear and 245/35/19 front. I had to do it temporary. It felt like I was driving a drag strip car with the rear jacked up Do a calculation with those 2 heigh differences and see if it coincides with your setup. 285 35 19 does not sound like it will work at all.....

#166 M5 wheels. but they will have tires on them as they are comming off a M5. I dont want to get 4 new tires since the rears are usable... Fronts wont fit and the only SAFE fit are 245/35/19

Damn my setup was very screwed up

I did that setup just testing the waters out. Ive ran alot of setups on my car. So much the threads on the bolts are starting to wear out

Your only .30 inches away also so I definitly wouldnt do it.
