ET30 on the rear, is this ok?

[BigWill]

Hi people, as some of you may already know I'm going for the Borbet T's soon and really wanted to have 7.5J at the front and 9J at the back, but the offset for the rear wheels is 30 (front's are at 35).

Is it ok to have ET30 on the back, and if so are there any drawbacks/problems I'm going to encounter?

Thanks for any help in advance!

Just found the same wheels on the same site, but instead of searching for wheels that fit my ibiza, I did it for a 2002 Polo and they came up with the Borbets at ET35 at the front and ET30 at the rear with 9J width. Would these be ok?
Link if you want to have a look: Borbet T's

Checked an offset calculator, and the rear wheels will be 23.75mm futher out than before

what size/offset wheels do you have at the moment?

Try here... http://www.1010tires.com/WheelOffsetCalculator.asp

I just put in Cupra wheels size and offset and then the Borbets and it says the borbets will stick out an extra 36mm. This should be fine IMO, cos most ppl add 20mm spacers anyway, so if you go without them and have a bit of stretch it'll look great

Thanks for the reply, I don't actually know the offset of my wheels at the moment, all i know is that they're 14" steelies and tyre specs are 185/60/14
