Thread: Learning to 4WD, in a Discovery Sport

There will be before/after photos of the mods too. Wish me luck.

You lot clearly didn't wish me enough luck. Bad AULRO, bad!

The lads at British Off Road are a pleasure to deal with but apparently the Disco Sport is less so when you try to rips its legs off. Unlike its Evoque and Freelander siblings which are said to be quite cooperative I'm told my DS is resisting hard against being dismantled. My hopes for a one-day turnaround have been thoroughly dashed and I'll be at home on the Playstation tomorrow instead of cruising up Ocean Beach in the winter sun.

Still, I promised photos. I can only give you "before" shots, obviously, and if you are silly enough to be interested in this process then you'll have to endure the wait for the "after" shots just the same as I am.

I put a tape measure against the front wheel and fender. Tyres are still down at easy trail pressure from Wednesday's drive, a bit below 30 (cold) on the 235/60R18s. The top of the 29-inch Goodyear is actually 28 inches above the concrete floor and there's a 12cm gap between the top of the tyre and the bottom lip of the wheel arch:

I'm hoping for that gap to be at least 15cm next time I measure it, since the new tyres will be the same diameter but the new springs will be higher.

Here are a couple of shots showing the stance of the car, the unadorned roofline and the 235mm HT OEM tyre in the arch at full lock:

Bring on Tuesday.

Don't have time to write much this morning, but it's a good news story. Got the car back yesterday afternoon and took the LONG route home through the mountains. I'm very happy: the combination of springs and tyres is well worth it for off-road use IMO.

Also it looks great. Not just my opinion, the guys at British Off Road liked it enough to make it their new Facebook banner:

They're happy to take on more like this if anybody is interested. Need to budget for 6-8 hours labour because apparently the Discovery Sport is trickier to lift than the Freelander and Evoque before it.

What are the noise levels like from the General Grabbers?

Also look like the 255 55 18's gave you a slight lift as well?

Really not bad. Hardly audible on the highway, just the tiniest drone at 60kph.

Only because of pressure differences. The photos I took of the old tyres were below 30psi after some track driving. The new tyres are around 40psi from fitting.

According to tiresize.com 235/60R18 is 29.1" and 255/55R18 is 29.0" height, so I should have lost 0.05" chassis height all else being equal.

That looks really good, fit for purpose. It will be interesting to see how this new combo goes for you, I think it should make a major difference. I would think you could fit a 30" diameter wheel. This would give you slightly more lift but also more sidewall height.

Well I didn't do it for looks, but I'm glad you're liking it. Based on the hour and a half of rough track I know for sure it makes a major difference to the driving.

I'm pretty sure the bigger wheel would fit, and yes it would lift the car even further, but doing both a suspension lift and fitting bigger tyres on a vehicle with electronic stability control is specifically forbidden under Queensland vehicle regulations. See the "minor modifications" document G19 here:
Vehicle standards instructions (Department of Transport and Main Roads)

Seems to me like springs and wider AT tyres is everything that can be done without engineering certification. Underbody protection is the other major thing on my mind but that's proving really hard to source outside of Europe.

Never noticed that section thanks to having suspension that lifts already.
Only read up on diameter, width and track width increase limits.

Yeah, the Discovery 3/4 sure have a leg up... so to speak. I am going through all the pricing exercises on the D5 already even though I've promised to wait until at least the end of next year before buying another vehicle. In the meantime, just have to wring every bit of fun I can out of the Sport.
