(S) alloy size

what is the the biggest alloys you can fit on my gp with out any rubbing on arches

225/40/18 anything bigger would ridiculous as for ride quality i think it would suffer badly even at the said quoted size

if you don't have a sporting, buy a set of them from your dealer or try ebay. don't get aftermarket monkey metal

and why not! nothing wrong with aftermarket alloys imo. especially if you get good tyres with them, they can be an absolute bargain compared to being ripped off by the dealer. maybe if this was a mercedes forum i'd be saying different because i can imagine their alloys are of the highest standard.... but fiat ones, i dunno. seem ok though and the petrol sporting alloys are nice!

Hi, I have a gp with 215/35/18s fitted with Eibach lowering springs that lower approx 50mm all round. I think the size of the wheels and the height of the car is now ideal. Ok, it is a rougher ride over the back roads and over speed humps, but on the other hand the car corners much better and sticks to the road like glue. Going along normal A roads and motorways, you won't notice a major difference in the ride comfort. These wheels don't scrape on the arches or rub on full lock, even after lowering. If you do go for 18s, you will need to get it lowered, otherwise you will have the 4x4 look. In theory you can fit 19s, but i think that would be too ott.

I have to dissagree with what you say - they alloys on a GP do not stand up to pot holes very well - if you search this forum there are many people looking for replacement alloy because of this, myself included.
You can now buy an aftermarket set of alloys for the price of 4 quality tyres with tyres included on them. I have used budget tyres on mine for a while and they don't seem to be much difference in them.

Have had problems with aftermarket alloys yourself - please enlighten us.
