Hello all, Questions pretty self-explanatory; I recently picked up a '13 Outback SX which I'm very pleased with but I want to swap out the stereo. It came with an aftermarket already fitted (Pioneer AVIC-F840BT) which is functionally sound for a unit from 2012 but I can't upgrade the maps, and the Bluetooth seems a little intermittent at times, so I'm looking for a solid Android-based unit ideally that I can Waze on and anything else I decide to sideload because I don't like the idea of shelling out £500+ for the Waze-enabled Pioneer units. Anyone have any suggestions that might fit into the little 6.1" gap in the dash? TIA!

Cheers for the reply so far guys, I realised the speedo would be out but someone mentioned I could get it recalibrate? Or is that just more hassle than it's worth? Also, I've had a look at the offset and I think it only pushes the rims out by an extra 20mm which shouldn't be too much of an issue I don't think? My major concern is the arch gap, where I lose over an inch of clearance, and I have no idea how to determine the maximum play in the suspension. Is there a way to figure it out, short of fitting the new wheels and pressing down on the corners? Last thing I want to do is hit a bump and ram the wheels into the arch.

Hello all, first time posting here and hoping for some advice. Never been much of a petrolhead but I picked up my first Scooby a few months back and I've been enjoying tweaking it. I've been trying to figure out what wheels I can get away with on my Impreza GX and after using a load of these "calculator" type sites I'm still none the wiser. I'm currently running the stock 195/60R15 on there but I've been offered a set from an '01 Forester at 215/60R16. Now, I've read enough to understand that when plus-sizing I should be keeping the circumference the same and reducing the tyre profile, whereas this gives me an 8% increase in size. Is anyone able to give me a cliff notes version of what sort of performance loss I'm going to be looking at, or whether I should just abandon the idea as they're likely to foul unless I play with the suspension? Cheers!
