need narrower wheels for exige s1 - advice please

Subject sounds strange i know.
But - I have the offer of a cheap brian james minno trailer but exige s1 is 4ish inches too wide.

Does anyone know of any standard wheel (much narrower) from any other road car that fit an exige.

if so i can narrow the track an get it on the trailer. and use spare cash saved on trailer on new wheels/tyres for track days.

thoughts ?

How will this help? The wheels fit nearly flush with the wheelarches.

Is the trailer a flatbed with no sides?

Spend the extra money you’d pay for wider wheels + tyres on a wider trailer ?
