Agreed! I stay with moderate lifts; had a 2001 Diesel Excursion I lifted to the sun on 37", lost just about every true capability other than looks. I did a remod and dropped it 4" lift with 35" (closer to 34") and the performance with towing and moderate off-road was perfect for what it could be.
Couldn't agree more with
@REDROVER on the H1; true IFS built for purpose, unfortunately our LR3/4 IFS need longer control arms and axles to get the full function/performance out of a lift anything higher than Normal/Off-road height due to driveline angles and ball joint geometry.
I'm on 32" and some change with BFG KM2 (17") and I will say its damn near perfect off-road. The wheels tuck in the wells at full compression, full steering lock to lock with zero rub and zero modifications outside of the brakes to make them fit and the braking force reduction is null due to driver awareness. I can go on an on with this mod and believe it is how the Disco 3/4 should have come and also any other modern Rover!
17" wheel or less is optimum for any, I mean any configuration for a true SUV because ultimately, the rubber that meets the terrafirma is the limitation with most modern traction controls! Jeep and Toyota have always stayed inside this window for tire options because they too understand where traction control and tire selection work in unison.
Still liking the Defender but just seeing the price tag slowly moving up and up on this thing with the marketing for true off-road going south. This thing is probably a beast off-road and they have yet to show it or them willing to take some significant trail rash and keep plugging along! Even the wives of the men who are drooling over the Defender for their next soccer club meeting can appreciate that when they pick up Johnny and Susie and their four friends for Chucky Cheese runs!
Off my soapbox!
