Hi Seb, welcome to Westfield ownership & the club. I see you brought ur’s from Toybox, did you sit/drive any other cars before buying yours? I think there’s no “std” wheel position & there’s a lot of retrofit options - size (diameter) and shape of wheel, detachable/fixed, bosses, spacers, etc - companies like Demon Tweeks sell every type & size. But I’d start with seat position! Are your seat’s adjustable, if so, with wheel off, set seats for your pedal box & a comfortable leg position, then hold the wheel in the ideal position for you. See where that is in comparison to its current fixed position. Then you need to make that distance up with different wheel & spacers.
Also see your in Shropshire & there’s a number of owners to meet up with to compare alternate set up. Local to you check out Shropshires & Mid Wales @Nic Chase (NICO) - Shropshire & Mid-Wales AO& Black Country @Rhett Turner - Black Country AO Meetings - plus if it helps, I’m in Wolves 2 miles from M54 Junc 2 if you wanted to compare my Fixed Momo as in photos. Cheers Phil
