Aftermarket Wheels: Offset and Width

Featured Replies

Good afternoon folks,

 

I know this or a similar question has been asked at least 7,643,982 times already but I'd just like to get a last bit of confirmation as I've trawled through and struggled to find exactly the answers I'm looking for. 

 

I've got a 66 plate PFL vRS wagon, 2.0 diesel, *not lowered*.

It came with 19" Extremes which I since sold and replaced with 18" Neptunes (massive downgrade, I know, but I wanted a slightly softer ride and also suddenly became strapped for cash a little while later). 

 

Anyway. Before I dive in and buy some more appealing aftermarket wheels for spring/summer, I'm just looking for some pointers by anyone who's done similar. 

 

I'd like to stay with 18s, hopefully these lovely 1Form Edition 1s, 8.5j et45:

Again, the car isn't lowered, and never will be until I inevitably change my tune and buy springs. These apparently fit the car according to the LK Performance website, and I've checked on willtheyfit and tyrestretch to settle on 235/35 tyres. 

 

Now to actually ask the question(s)...

Has anyone fitted this size of wheel and tyre to their Octy and is willing to share pics and pointers? 

Also, without lowering and fitting sketchy stretched tyres, what offset can I get away with on an 8 or 8.5j wheel? Also possibly without spacers. 

 

Thanks for sticking with me on this!

Almost no one makes a 235/35R18 tyre size.

 

The outside diameter is too small.

 

Outside diameter of tyres

225/40R18 637.2mm

235/35R18 621.7mm (2.4% smaller outside diameter compared to 225/40R18)

I remember you telling me the same thing when I asked :D

My bad, I meant 235/40. Been looking at tyre sizes most of the day and started to get numbers mixed up 🙃

This is my FL mk3 with 18 x 8j et45 Protrack ONE - 225/40/18's PS5's on h&r springs. .

The facelift mk3 vRS has a 38mm wider rear track than the preFL - so basically like it's running 19mm spacers each side from the factory.

 

So 18 x 8.5 et45 on a non lowered preFL car will fit fine. . .I've seen 19 x 8.5 et45 on a lowered FL MK3 and it's very tight in the rear arch.

 

One thing I looked out for when changing was the weight of the wheels, alot of aftermarket wheels are actually heavier than the oem equivalent. . The Protrack ONE's as above are 3kg ligher PER corner. .the lighter unsprung mass makes a noticeable difference.

If this is a square setup (same front and rear) the fronts will sit quite a bit out. 

 

Willitfit.com says the outer edge of the rim will be 18.7mm further than stock. Generally, most people put 15mm spacers on the front and 20mm on rear. I personally think 10mm front and 20mm rear provides a nice look.

 

Here's mine with 20mm rear spacers and 5mm front as an example (mine is lowered 20mm all round) and you can see the front doesn't need loads more.

If you can go for a staggered setup rather than square I think you'll get much better results, otherwise I think it'll look overly dominant at the front. That is just my opinion though and depends on the look you are going for.
