If you want the opinion of non-boyracers {snip}


That's pretty offensive really. If someone wants to improve the look and (maybe, depending on model) handling of their car, that makes them a boy-racer?  
You know where you can stick that opinion.


Have a look at the 3rd comment of the thread.



And no "boy-racers" have answered. Nobody said "drop it on the ground and put 24s on it, yo" did they?
But you insinuated that everyone one that said "bigger wheels are fine" is in fact a boy racer.

here's the boy racer answer

20"rims is best, yeah the ride's on the hard side, but everybody gets used to it.
while you're there, make sure the offset is increased so the tyre protrude out, and the somemore. you can always give it more negative camber to make it get closer back into the wheel arches.

also lower the springs, and get adjustable shocks while at it.

that's step one. there are other body kits and a custom kits. custom front lip, custom wing.
straight 3" exhaust.
custom tints.

You forgot about stretch.. 

Buy 195/25r20 and stick them on 12" wide rims... oh it's hard to get them to stay on there, but once they do, totally sik, chur.



Here ya go OP, thank me later!

Thanks for all the feedback guys. I think I'll probably go for the 18", since that was a factory option the ride should be fine.

ride quality will be worse than 16" but will be ok, an optimum.

ride quality also depends a lot on the tyre. cheap tyre = noisy, some expensive tyre = not so noisy :D

Blimey.  They'll need to give the cops thinner notebooks to test the ride height on that!

Ride height is only one of the issues here. That camber is now also illegal.

Genuine question.  On what basis is it illegal?
I'm not a fan of the stretched tyre look anyway, and that level of camber sure doesn't help performance as only half the tyre is in contact with the ground.

I never knew there was a legal limit to ride height. Or do people mean wheel clearance

http://www.lvvta.org.nz/faq.html

If the suspunsion is lowered you need LVVTA certification, and the car has to have "adequate suspension travel and clearance to bump stops, and that the suspension performs correctly. The LVV Certifier will make the decision as to the appropriate suspension heights, which will be recorded on the certification plate."

The pictured car will fail that test.

New rules are as follows: "A front or rear suspension system in a low volume vehicle must incorporate no more than half a degree
(0 degrees 30mins/0°30’) more negative camber than that specified by the vehicle manufacturer."

the car above would be well outside that.

Depending on how "specified by the vehicle manufacturer" is defined or interpreted, my race car (road legal) would also fall into the non-legal category.  While it's running factory suspension, it's been pushed to the maximum that the in built adjustment will allow which is about -2.2 degrees.  This puts it outside what most wheel alignment machines suggest is the range it should be within.
Also, give the potential adjustment range that quite a few cars come with from factory, what is defined as being specified by the manufacturer?
So on one hand you could say that it's within the limits of the factory installed hardware so should be ok.  But on the other hand it's outside what the wheel alignment machines say is the maximum.
I'll deal with it completely at some point in the future by installing fully adjustable suspension and getting it certed but for now it's in a grey area.  So long as the WOF inspector is happy I don't mind overly much.

It's actually quite simple really, the manufacturer specifies a set camber from the factory with an allowable tolerance (also set by the manufacturer), this is in the service documentation for every car. That +/- 0.5 degrees is the max you are allowed.

 

 

 

There are however exemptions for road legal race cars but they require certified paperwork from MSNZ.

also most modern cars do not have large amounts of freedom to adjust camber.
you would be lucky to get more than -1 degree up front without rejigging subframes or other tuning tricks like camber bolts or drilling out strut mounts.

I guess I forget that Subaru gives me the camber bolt adjustment from factory which a lot of cars don't have.
