Did that thing even have "geometry" Harry?
Seriously though, I'm hearing you all fellas, and am somewhat aware of the the possible negatives of going as wide as reasonably attainable, but, and it's a big but, do the positives outweight the negatives?
I've spoken to a bit of a local "guru" up here whom designs race cars from scratch, not sedan cars though, more your open wheelers and "sports cars", and his formula is telling me I need width, more width in fact that I can cost-effectively obtain.
I've never really been able to get my head around the finer points of geometry, for lack of interest if I'm honest, I'm really just a bloke who gets in and drives the thing, working around its foibles. I'm certain my 32 as it sits now (virtually stock with a set of Apexi coil overs and some camber bushes) has PLENTY of negatives, but I don't notice them, and the thing is pretty quick!
I get people PM-ing me asking what setting I use or what it has, I tell them, and they tell me I'm wrong! I then go and smack them by five seconds a lap.
So, I'm wondering, if I widen the track by a total of approx 80mm, and run a 10% wider tyre, leaving the geometry how it is.... will it go faster or slower?
