how big can i go

[S7000EY]

what size are the biggest wheels you can fit to the zs without needing to modify the arches?

cheers

Not sure, but there was something on here going for 19's.

I have got the 20's but if I'm honest I think I have more chance of a blow *** off the pope than them fitting I just don't think the arches can be pulled and rolled enough without also needing paint!

It may of been a different story if the offset was nearer and machining them a bit will be hard as there isn't much to play with!

On a plus though someone wants to buy them off me for a nice little profit!

Will suit a touring car replica with race arches then!

Just by visually picturing the wheel and tyre in my head I would guess 19's are probably the biggest you would need to go purely because of the rolling diameter of the overall wheel. Any bigger alloy size wise is going to require seriously ultra low profile tyres to the extent they are just rubber bands wrapped around it otherwise you will exceed the original rolling diameter. Secondly any increase in rolling diameter will reduce the 0-60 performance albeit only slighty and reduce torque at the wheel but will increase top end speed very slightly.

Would definately go on the touring car ZS RSM have but I have sold them to someone with a 5 door 1.5d megane!!!
