Wheels Widths and ET. Expert advice needed.

Post by GHOST »

Been biting the bullet on a new set of wheels for a couple of months now. I've seen a few I like, including 2nd hand ones but I'm fancying these:

http://www.driftworks.com/rota-gtr-17-w ... lours.html

So, if I go for this...

Front 9" ET25
Rear 9.5" ET30

...Are the wheels going to stick too far out, and are the fronts going to stick out more than the rears?

Also, are my new tyres, fronts 215-40-17 and rears 245-40-17, going to fit ok?

And one last thing. On a sonic shadow, Gunmetal or bronze?

Front
9" is to big for the front plus 215 will not fit on the front wheels

8" is the size I would go for with 225/45r17 rubber
Rears
9.5" may fit and 245/40r17 would be the size of rubber

In my personal opinion the best sizes are:

17x8 et35 front (215/40/17)
17x9 et38 rear (255/40/17) or (245/40/17) to prevent rubbing on the rear arches if they aren't rolled

These sizes fill the arches perfect.

This up front is about as extreme as you can go without being beyond the arches but still missing the suspension struts/cups on the inside.

Your tires would be fine on 17x8 and 17x9 ... Being 245s you have for rear tires you are less likely to have any rubbing on the arches at the back. I have this problem when I hit a bump on our shocking roads haha!

I have photos I could show you of how mine fit but I'm Unable to upload from flikr on my phone as the app is horrendous. There are photos in a sales thread but I won't post a link incase it's taken as a shocking sales pitch attempt haha!!

Those sizes you have posted won't work buddy on standard body trim.

On a sonic shadow I'd say gunmetal or black mate.

You will be able to get those wheels in the sizes you need though no problem. Even 17x7.5 et35 and 17x8.5et35 works well. I used to have rota D1s in these sizes and they fit really nice too. I'd imagine you can get the rota gtr in those sizes too

I am certainly no expert but after punching your values into this calculator

http://mr2.gordaen.com/wt_calc.php

You are likely to have problems with these, especially the fronts as the offset are low and 9j is already a wide choice for the front as said above 7.5j/8 would be a better choice for the front.

As for the rears, I was interested in a set of wheels with 9.5j rears, the owner claimed he ran them no problems but the guys on here advised against it and they were ET35, these being ET30 poses more of an issue as they will stick out 5mm more than an offset ET35. 8.5j/ 9j would be a better choice but it also does depend on offsets!

The calculator probably is not 100% accurate but will give you a good idea! Punch in the figures and have a mess around with sizes and offsets!

Go bronze!!

Set the parameters at the side to 17" et35 and 5x114 and it comes to with two options:

17x7.5 et35 and 17x9 et35

These would work and work Well with your tires too

Not the same model but there are pics of Rotas in following sizes 17x8J +35 & 17x9J +37 here:

Cheers guys. Didn't even know about that website. Just presumed they only came in 9 and 9.5" like on the drift works site.

So...7.5" front. And 9" rears. Both ET35. Can't understand why they don't do an 8" rim though.

They may do an 8"... Let me look on the net for 5mins :)

Edit:

Couldn't find any 17x8 on these at all. Yet they do 17x8 on other styles of wheel.. Which is strange

That's what I thought mate. Very odd.

So would ET 30 stick out too much and rub on the arches under load?

I wouldn't go too wide on the front, the 8"/245 wheels/tyres mine came with tramlined badly, I've since replaced them with 6.5" on the front which handling wise are far better

Front 17x7.5J +30 or 17x7.5 +35 and rear 17x9J +35 should fit but depending on tyre widths you may need to roll the arches to avoid rubbing.

It's worth remembering that a wider alloy is only useful for fitting a wider tyre. There's no point in having 9" or 9.5" alloys on an mr2 really unless you roll or extend arches and fit 265, or 275mm tyres.

Even an 8" alloy will take 245 tyres. An 8.5" alloy will take them with less bulging so that's as large as you ever need really.

www.tyres-pneus-online.co.uk/equivalenc ... dvice.html

Would suggest looking for a 7"/8" set up, or 7.5"/8.5".

Otherwise the advice in this thread is all good! Your initial specs were way too large, and IMO you don't want larger than 215mm on the front.

All excellent advice thanks.

I'm guessing that those wheels are off limits to me as they don't do them in an 8 or 8.5". 7.5 would be fine for the front but the 9" might just be too big.

17x9" + 25 will be a challenge on the rear. Maybe with stretched tyres - if that's your thing.

17x9.5" + 30 being the alternative... Probably a tough job too. There's nothing to say you can't have your arches rolled - you just need to factor the cost in.

The ideal would be 9"+35s, i.e. 10mm further inboard than a +25. You may well get away with a +25, but the tyre will certainly be outside the arch. On stock suspension it may not contact the arch, I couldn't say for sure. You could perhaps remedy the situation with some fairly extreme negative camber, or stretched tyres as mentioned. The +30 of the 9.5" wheel is better, but the wheel being wider means you face the exact same problem and the fitment will be more or less the same in terms of outside arch, but more likely to contact your suspension strut on the inside.

Another option you could explore would be having GTRs on the front and Grid Drifts or something on the back: http://www.driftworks.com/rota-grid-dri ... heels.html

Image

Or, obviously, Grids all round. Depends on your tastes. Grids are the most popular Rota wheel by far, and there are accordingly loads of available fitments.

Or - if you've read this far you deserve this - check out another retailer for a 17x9+35 ;) http://www.rotashop.co.uk/rota-gtr-17-9 ... 040415.htm

That's a what I was looking at for the rears mate, 9j at ET35 with the 7.5j on the front at ET35. From what I can gather though from the other posts, my 245 width tyres might not be wide enough for a 9j wheel. Is that right?

245 on a 9" wide is totally fine mate trust me. I have a set of wheels I'm packaging up for sending to Cardhore and the 9" rears have 245s on them and they are fine.

Those wheels in the link I posted yesterday with your tires will be fine size wise.

Great. I might go for those then. Just not sure whether to go for gunmetal or bronze. The gunmetal looks quite dark. Shame they don't do the silver GTRs in that size

They'll fit on a 9" fine. It's just that it's kind of a waste of a 9" since you could equally fit them on an 8.5 or even an 8 and save yourself some weight.

Look what I found:

http://www.mr2oc.co.uk/hwdphotos/upload ... e17b6c.jpg

7.5" and 9", all ET 35.

I think thats the gunmetal and it almost looks black. Shame to hide such a nice set of rims under such a dark colour. Tempted to go for bronze but undecided.
