P30 Suspension Confirm lower then non-P30?
Thanks guys.
Im trying to do some math on 20" wheels and tires based off another forum members information on his non-P30.
I don't want to f' myself and buy a set that rubs like hell.
From just looking, i honestly cannot tell the difference in ride height from a P30 to a non-p30 car.
Did you guys notice the bulges on the hood are different in the 2012's but that's another thread.

What you could do is measure off half the diameter of the tyre size you are interested in onto a piece of string and mark the appropriate length. Then place one end of the string at the centre of the wheel hub and swing the other end over the top in an arc. This will show you approximately where the tyre will be in relation to your fender in elevated view.
The car needs to be on level ground, you need to take into account the additional compression of the springs when you have the weight of passengers in the car, the compression of the springs that will be caused by the up and down movement of the suspension when negotiating dips in the road and cornering etc, and remember the outer edges of the tyres are rounded so they will not be at exactly the same dimension as the centre of the tread.
If you add to this any info on tyre/rim width and rim offsets you will get a reasonable indication of where the tyre will place. If it’s touch and go, I’d use the rule that it will rub.
