Tyre grip level question.

I can't really answer your question as I've never had 225s on mine but I can tell you that on mine there is a MASSIVE difference between Yokohama AVS 205s and 888s. They 'hum' a lot more than the Yokohamas as you'd expect but really hang on well.
I'd be interested to hear how you get on with 888 in 205/40x17s though as I'd like some for my Compomotive wheels rather than the T1-Rs I've got on there presently
Hope you get some more helpful answers

Toyo R888 track tyres only do suitable for 8x17 rim either 205/40 or 235/40.
The 235 are getting too big, diameter and cause all sorts of arch issues i believe. So your left with the 205
I have discussed with Toyo in the past about making a 215/40 but go nowhere.

I heard that due to the stiff sidewall and squarer profile of the Toyo R888, in 205 section its the same kind of width as a 225 road tyre eg Toyo T1-S, Eagle F1 etc

No way would i go for 45 profile on 17 rim, the overall diameter will be massive approx 635mm, in comparision to std wheel/tyre of about 590mm.
What i may do is search for suitable 8x16 wheel (if there is one) to fit over my 335 brakes and get 225/45 16 that would be spot on.

The R888 spec sheet details
225/45 17 inflated diameter of 25" = 635mm
205/40 17 inflated diameter of 23.5" = 596.9mm
as comparision
205/50 15 inflated diameter of 23" = 584.2mm (Standard tyre size)
so your are talking 2" (50.8mm) larger diameter than std , and this data is from Toyo spec sheet.
225/45 16 inflated diameter of 23.8" = 604.5mm is maybe more suitable if 16" wheels can clear brakes. I've just spoken to Compomotive and got a brake spec sheet to fill in and send to them for confirmation if 8x16 MO will fit over my brakes.
Unless you want to mutilate your arches you really do need to consider diameter as well as width. I'm in exactly the same boat.

Larger diameter Tyres...
I'm no expert,....
but the car will ride slightly higher
tyre will reach further into the arch (incresing the likelyhood of rubbing on arch, liners, etc, particulary on fronts during steering i would have thought)
slower acceleration and higher top speed (although these maybe minor).
I have always aimed to be as close to std diameter to prevent issues, cos that makes sense to me, and i imagine alot of design went into gearing, suspension etc when that size was chosen originally.
