Do you recon a 300mm steering wheel would be too small…??
I know its down to personal choice but what have you lot got size wise… OOOPS, that sounds rude…sorry.
Blimey mate, whats it off, an action man jeep?!
If you have plans to make your interior look modern / sporty (carbon fibre dash etc etc) then I’m sure it would look ok (afterall taste is subjective as I’ve learned the hard way on here!) but there are plenty of ‘normal’ sized wheels that will give you that look.
The thing to bear in mind is will it be controllable? Sounds a tad small for the normal ‘2 and 10’ position.
Nice lights! 
I’d be concerned on how it would affect the visibility of the instrument cluster???
There’s a danger it might just look out of place???
I had a 300mm wheel on mine for a bit, couldn’t read the speedo or the rev counter. Steering was a smidge heavy at parking speeds (no PAS). I took it off because I love it (it’s an old chunky Momo I bought in the 90’s when I worked in part of the Momo group) and drifting was wearing out the leather.
I can’t remember if it “looked” wrong or not.
My current wheel is 330mm and does everything a steering wheel should. I know this because I never, ever think about it. Zero flaws. A bigger wheel would hit my knees I think.
Avoid wheels with flat bits and wheels which are eccentric (offset up a bit) as they give more room for your knees when you’re going straight then trap your legs when you go round a corner. Hate them. My other car has one and I can’t replace it. Awful.
I’ve fitted a MOMO Race, It’s the 320mm one and at parking speeds with my 195/45/16’s it can be a bit like hard work (No PAS).
I’m 6’1" tall and I’ve got quite long legs, I needed to get a smaller wheel so I had somewhere for my knees to go. My heads around 2" off the hard top and I can’t see what my oil pressure, fuel or temperature gauges says without stooping a bit.
I’d prefer a slightly larger wheel but then I wouldn’t fit… Maybe after I find and fit some Elise seats I could do it.

I have just fitted a 25mm spacer behind my OEM Momo 370mm steering wheel and this has moved the steering wheel closer to me and further away from my legs. It’s a bit of stretch to the indicator stalk now but at least my thighs are not trapped under the steering wheel anymore. Operating the brake and clutch pedals is less awkward as a result. I can also see a little more of the top of the instrument cluster and my arms feel more comfortable, given that I am 6’2" and my seat is slid all the way back to the rear wall.
