Will these fit? Help with different offset / poke

[junglist]

I'm currently running 108’s which have the following spec:

Front: 8J / et47 / 5 x 120
Back: 8.5J / et50 / 5 x 120

Proposed alloys:

Front: 8.5J / et30 / 5 x 120
Back: 9.5J / et35 / 5 x 120

On the rear running the same size tyres (235/35/18), I should get an increased poke of 27mm.

On the front running the same size tyres (225/40/18) I should get an increased poke of 23mm.

Would I be better going for a square setup of 8.5 all round? 27mm seems too much and 23mm would probably be pushing it? Might require arches rolled? I had to take my 20mm spacers off on the rear due to rubbing, fine with 15mm though.

I know there will be a slight stretch on the tyres but this shouldn’t be too exaggerated?

For what it's worth the car is lowered on Eibachs.

Appreciate any help. I'd have to order the wheels from the US so the last thing I want to do is get them and find they don't fit / cause rubbing. The idea is to use the new wheels for shows / meets and then stick the 108s on for road trips / drives where the car is going to get some stick and there’s more chance of rubbing.

Cheers!

The rear wheels will fit. My rears (19's) are 10'' wide with an offset of 38. You can easily get away with 255/35/18 tyres.

The fronts may well rub a little on bumpy roads.

Thanks Ben. Would you recommend some slightly narrow tyres on the 9.5 rear or stick with the 255? Same for the front, the "stretched" look doesn't bother me either way but if it helps reduce chances of rubbing I'll go for it.

I'm also wondering if the car is low enough on Eibachs to pull it off. :lol:

You can go with 265 on 9.5" ET35 without rubbing.

How will 9.5J / ET35 with an increased poke of 27.7mm not rub when the standard setup and 20mm spacers did? ie 7mm less? Am I missing something?

Well I have 10" ET41 (outer position is the same as 9.5" ET35) with 265/30-19 Michelin PSS (pretty wide for 265) on my coupe. Also tried 3mm spacers once. Barely touched the fender but drivable also at the track. So with another tire brand ET38 would work without rubbing.
Also tried 9,5" ET35 with 275/30 Nankan NS2. A little rub there too. But not much.
My coupe is lowered with H&R springs (35mm) and M-Tech shocks.

I'm running 8.5 front with 215/40/18 on and rear 9.5 with 235/35/18.

cars lowered 65mm on spax coilovers and I barely get rubbing. Only when I go over speed bumps.

Even considering sticking some spacers on.

looking good Mr shanahan... how do you rate the spax rsx coilovers?
