I believe to fit tyres larger than the 15mm oversize offered as an option you only need to upgrade the brakes to those from the up-spec XT. I may be wrong however as it seems the rules are being rewritten as fast as we can read em lol

^I have re-read the VSB14 and I believe you are correct, Nachaluva...

See attached link to the relevant VSB14 section (LS), read item 4.11 from page 28... As far as the VSB14 is concerned, even if your Subaru is classed MC, it is still a softroader subject to normal car rules, so a TOTAL lift of 50mm is approved without certification.

This lift can be obtained by a combination of smaller suspension/tyre lifts provided:
- Tyre diameter has not increased more than 15mm
- The total lift is equal or less than 50mm

The link is here

Cheers,
Pedro.

I asked my engineer tyres greater than the 15mm limit while having my H6 conversion certified. Technically, yes, they can. But i was told In no uncertain terms "No, and no one else is Victoria will certify them either". Extra unsprung weight, greater forces acting on the wheel bearings, overall gearing ratio change, decreased braking efficiency, increased centre of gravity...

Braking and hanlding test they can account for some of those things. But increased wear/forces on suspension components and bearings they cannot account for. Just too risky for them to approve.

^ I have heard of that too Venom. I notice that when I go from stock size subaru tyres on 16" rims to my larger, heavier offroad tyres on my 15's that my Forester drives like a different car.
Very slow to accelerate, braking takes more effort at the peddle, grip onroad is a huge issue, gearing is noticeably higher, cornering is where it is noticed the most though. The general lack of traction, grip and feeling of the steering is quite worrying in my vehicle. It's a compromise I am willing to take though.

Yep, they "can" but "won't". Wouldnt surprise me if someone finds an engineer willing to give it a bash though, so to speak

^ I honestly thought about it... Made enquiries and tried looking further into it. Gave up when it felt like it was a "secret society" sort of club. The criteria to let you in are not clear neither is the list of requirements.

I'm affraid that - to an extend - we have to live with this money grabbing exercise so these guys can pay their massive trade insurace premiums for the sake of the 2-3 idiots that push it too far and cause accidents and get them sued for signing something off.

Pedro.

You ought to see the Professional Indemnity Insurance premiums even for accountants, Pedro.

Even as a sole practitioner running my business from my own office, it cost me around $30,000+ p.a. fixed costs just to be in business (including my PI insurance of around $2,000 p.a. then) ... AND that was 15 years ago!
