You talk about ride and fuel economy and yet you want to increase weight by fitting unnecessary steering gear and silly tyres both of which will do nothing for fuel economy. The ride on the P38 as standard is among the best I have experienced...
I had 32s (“) on my p38. They won’t fit on as standard - no chance don’t even try it. Trust me It gears down and speedo reads wrong. You get used to it as it’s only few mph here and there until you get well over 100.
Don’t help your mpg i...
It'd be interesting to see the results. I think correct pressures and road tyres (rather than some chunky A/T tread things) would have the most impact though.
I think you will have trouble with the tyres rubbing the wing when turning with the car at normal height . also i think you will have trouble fitting the spare in the well in the back of the car
You’ll likely drop a few MPG - yes they’ve got a larger diameter so distance covered per rotation will be greater.. but they’ll weigh more. More mass, more energy required to rotate.

This can be quite a good site to see size differences and speed changes. Most speedos over read your actual speed, so indicated 60mph could be actually be 57mph for instance. Provided you don’t go too far bigger...
Speedo may be wrong and technically they may be illegal as not homologated for the vehicle. Not much notice is taken of these things in the UK, but it may affect your insurance.

Again, I think you're over thinking this. It's a very...

You use a 75W90 oil.
Wether is has Molybdenum in it or not will make little to who-ha of a difference.
Semi synth or fully synth, it doesn't matter it's in a differential of a road car in the UK.

One arm is slightly longer than the other, they look identical but are not.
If you look at the caps covering the wiper arm nuts, there is a little slot you use to ping them out with a thin flat blade screwdriver.
If I ever get round to doing this upgrade and if I remember ofcourse il report back.
I'm unfamiliar with the word plenum? Is that the plastic panel under the outside of my windscreen?
