Hi All,

Disco D1, V8 carb, manual, 3 door.

I have a dilema, to put on a 2" lift or to fit larger diameter tyres...

..budget won't allow me to do both yet.

My understanding is that a lift will give me greater axle articulation helping to prevent loss of traction due to wheels lifting, presumbly a greater ability to clamber over obstacles too. The downside I see is that the COG is raised, making my otherwise unstable Disco even more so. I don't mind the truck wallowing on the road as that means she's nice and flexible off the road.

Tyres on the other hand offer a different set of benefits and disadvantages. I've already gone from stock 205/75's to 235/85's, they gave me about a 2" axle lift making the ruts and rocks easier to deal with, the downside is that I had to do some surgery to the wings and I've no idea what my speedo reads now! I like the idea of going even larger to 255/85.

Has anyone here any experience of the pro-comp lift or has anyone put that size of tyre on their disco? I would like to hear your experiences before I make my mind up.

Cheers,

Mark Holland-Hicken C21-Design

235/85 has put your speedo out by 8% :-)

Any more questions - give me a shout, or click the forums or live chat buttons on Piglets Place ;-)

Mark,

If you join the forums...someone is selling spacers to lift Discos/Rangys for good money....

So Neil Brownlee was, like

I've gone to bigger tyres on both the 90 and the Series (205 to 235/85 both times) and I found in both cases that a check with GPS revealed that the speedo was now spot-on (say within 1 mph at 50). I've since spoken to a number of people who have seen the same effect. I wonder if the 8-10% difference in gearing compensates for an 8-10% over-read built in at the factory stage. AIUI, speedos are allowed to be out by up to 10% over (and

0% under), and I wonder if manufacturers routinely make their speedos over-read by some amount as a matter of course. A) guaranteed to stay within the law, even with loose manufacturing tolerances, and B) makes the car seem a litle bit faster than it really is.

I think landrover speedos are just fairly vague, especially series ones. On my series (2/2A/3), I have a nice mixture of bits, including bigger wheels. My speedo (with a new cable, replaced head and new gearbox) used to be exactly accurate according to the GPS.

6 months later, nothing has changed except my speedo cable snapped and i put a new one on. It now reads 10-15% lower than it should.

Ironically, bigger tyres is the better option, as it is the only way of raising the diff, which is the lowest point. But in order to fit bigger tyres than you already have, you're gonna have to lift the suspension to fit them underneath without ripping things out under the wheelarches........

Hi Niamh,

So, as I said I can't do both... ..what's the bottom line including shipping?

Very few of us can afford all the toys in one go.

Question....what are the tyres you have on right now like? How many miles done? If lots left, you will loose a bit on changing now and I would opt for the 2" lift. If new rubber is needed, I would go tyres first.
