ok this is my take on it, 10 inch wheels look cool great for track work but hard work on the road with or without PS, watch out for the lorry tracks and don't do more than 40mph in the pouring rain as you will skate from lane to lane, this is all from experience

I would have thought wet weather handling is heavily dependant on tyre compound?

I have driven cars with 10" + wheels in pouring rain and didn't suffer what you describe above ( albeit these are moderns compare to s30 chassis) and they were equipped with high performance ALL weather tyres.

Mine is savage, depends on the tyre and the geometry. The car wasn't designed for them

I keep looking at wheels and the decision to buy has come up again. These a for a factory arched car that I will be lowering. I could go the popular 8x15 et0 but really would like to run 9's, also in zero. I'm happy to run 205 tyres and I'm wondering if I roll the top lip a little, could I get away with the extra 12mm. Working on the principle that a 225 will fit then in theory I'll only be 2mm wider at the tread area. I may have to try a zero offset 8" with 225 tyre and see how much room I have.

What profile are you contemplating on the 205's? 50\55\60 ? So long as you have good strong suspension then I suspect you may be ok with the lips rolled.

You need to watch the back space as you might find it fouling on the suspension .when I had 225,50,16 on my 16x8 rota +10 they was just catching on my wheel arch when going down bumpy roads ,so I used 205,55,16 no problem.
Tyre choice will make a difference as side wall profile varies between manufacturers.

I ended up buying (but out of stock till feb) 8inch 0 offset for front and 9inch -15 offset for the rears, will be going Gaz coilover too.

I'll be running coilovers of some description but not just yet. This will be my runaround so will evolve with time but still be primarily a road car. Can't see it ever hitting the track but want it to look right.

Are you running stock arches Rich? Tyre size?

I will be using wider arch's once I find some plastic ones(looking at ones from OZ) but not at tyres yet as will wait till I get the alloys.
Not done anything on the car yet as I need to finish my other project but did throw the saab engine in and its looking good so far.:thumbs:, got a 6 speed mazda rx8 gearbox to mount to the engine.

After much searching and head scratching/umming and aarring, Im thinking of buying some 16x8 alloys, but the ones i fancy arent available with 0et, so i would have to go with +10et
I would be happy to have 15" wheels but tyre choice is pants and will only get worse :( so 16" it is

I see you have the same spec of wheel Im considering, what suspension set up are you running?

Mine is standard struts but lowered by approx 1.5 inches, and uprated shocks, i have 225 60/14 tyres on 7j wheels and they just miss the rear arch, but only just!

The main thing Im concerned about tho is the wheel/tyre rubbing the suspension with the + offset moving it that bit nearer
I will prob go with 225 50/16 tyres or maybe with a 45 profile, I really like the look of a 225 wide tyre and would rather not drop to 205, not on the rear anyway

My car was a USA spec 240Z which are quite low compared to the UK version.
Like I said it was only just catching on the wheel arch so you may be ok with 225/50/16 tyres

you'll not have any issues with 15" tyres at all. 45 is not much profile at all.
