I've got 19s with the same widths and have et35 all round and have no problems even with the car lowered on eibachs.
The only difference is that I have 225/35s on the front which are obviously a slightly narrower tyre. This set up will also keep your wheel circumferencre front and rear almost identical.
I've got 225/35/19s front and 265/30/19s rear and as I said that will keep your rolling radius the same back and front and with the narrower fronts you will have less chance of rubbing.
I have Avons fitted on mine and I know Falkens are a popular choice.
Plenty of threads on tyre choices.
You will obviously won't be putting runflats on 19s as the tyre profile is so low you could lose your teeth on rough roads.
The lower the offset the further out the wheels position on the hub so I would go for et35 as that will move the wheels out 10mm more than the et45 and will give the car a better looking stance
Which wheels are you going for?
