Wheels and speedos

Hello,

I've been offered a set of 110 wheels - will these fit onto my 88"? What should I look out for? Or should I just wait for some 109 wheels? I'd quite like to set mine out a bit wider while I'm at it but not sure where to start. I'd like to be able to straddle the speed bumps like I can in my other car!

Also, at some point I'm thinking of upping the torque / power of the 2.25 petrol with twin carbs and a faster cam. Once I've done that I'll probably go back to Range-Rover diffs to get a better economy / less earache / faster motorway driving.

As I'm likely to swap around a fair bit are there any options for electronic speedos?

I know my mate got one for his kit car where you could reset it for different configurations etc but not sure if there is one that will fit easily in a Landy Dash.

Also, do you need to tell DVLA/VOSA if you fit a new speedo?

Cheers

Dom
