hey guys
just wondering when i go to get my 1200 engineered for sr20.
what is the widest wheels i can run on them
it has bolt on flares.
i have 14x6.5 ssr starshark wheels on the front.
but 14 inch stockos on the rear.
was wondering if it was legal if i filled the flares with 14x8 rears and could get it engineered?

pretty sure that is up to the engineer, as they can engineer it for larger wheels.
the widest you can go unengineered is 5 or 5.5 inch i think

all i know as i got my 1200 sedan engineered recently is that due to the weight of the vehicle the widest i could go was 6"

just do it!

Id keep the 14 x 6.5 it will be enough for grip
if you had good quality tyres.

25mm wider than stock, so that makes it 1 inch, so 5.5 is widest leagl by vic roads and adrs.

unless you can prove it had 5.5 inch steelies from factory
which I did with a later tire chassis sticker on one of
my old Mazdas.

not on a 1200, they all had 12 x 4.5 in aus so 5.5 biggest.

Like the engine swaps, you really need to read this in vic- vsi 8

i know its 2003 but until the national system gets the nod and agreement form all states, it still stands.

In NSW it used to be & still could be that the widest wheel for a car under 1000 kg was 6 inches. The heavier the car, the wider the wheel could be. It had nothing to do with whats on the tyre placard, as most insurance companies will try & tell you. The 1200 came standard with a 12x4 inch wheel so we'd all have to find 5 inch wide wheels. I think you can get them engineered with wider wheels, but it's up to the engineer & you're stuck with that size unless you want to re-engineer the car. If you're putting an SR20 into it, surely you've talked to an engineer. I'd suggest you give that engineer a call & ask his opinion. A 6 or 7 inch rim with some 185-195 wide tyres has plenty of grip. Another thing that I found out is that the wider the tyre the less weigh there is on the contact patch of each tyre & the less grip you get, & the more likely it is to aquaplane in the wet. I've run 175/60 x14's on 5 inch steelies as wet weather tyres before, as well as 185/60x13's on 6 inch rims. This allowed for good grip & good wear. I seemed to always get 2 years running out of a set of tyres. Even when I was delivering pizza's I'd get 12 months worth from the Sunny I had, with some 195/60x14's on 6 inch rims. I reckon the 14x6.5's you've got with some 205/55x14's would be a good thing, because of the extra weight of the car after the engine swap.

Some good advice here, especially too wide issues with lightweight cars
