Kumhos are OK, but Toyos I could never along with in T1-R guise. On the Pug 205 the CF-1s worked well on the road (I must be an anomaly here, since they really seem to suit that car, with the other owner agreeing), yet on my 306 (very similar suspension setup) the T1-Rs were not great, even after having the geometry checked etc. On other cars I did not warm to them (Clio 172, the odd BMW (4WD VAGs they were fine with I admit)).
On other cars Contis have never dissapointed but their life is not what one would call long lasting. Yes I know N rated tyres may be biased towards 911s but there is a night and day difference between how my S2 (on KU31s) and my Turbo drove. Ok, the suspension may play a part, but the grip this thing has is head over heels my old S2 (which was not terrible I admit). The 951 is on N0/N1 Michelins. The life of them (as I have found with Michelins in the past) is surprisingly good as well (on my daily, I see around 30k out of the fronts and that is not pure motorway work (it does have 1/2 the power though)). Even on the Turbo the rears still have plenty of tread left after I covered 7k in the car (they were changed at some point in 2011, so I reckon they have done around 8-9k).
For a weekend driver the Michelins would probably be overkill, causing me to sway back to the Contis. Bridgestones I admit do have hard sidewalls, but at least you can feel what the tyres are doing over the squirmy Toyos (on my 306 Gti-6 I did not ever get 7k out of them before they were illegal, and that was with me not putting my foot down (I think 34MPG average may aid that when most struggled to hit 30). Goodyears have been good tyres as well I would say on the various motors I have driven with them.
The biggest issue for you IMO will be the 16" part. Whilst the front should be cheap (they are quite a common size on many repmobiles (Mondeos, Foci, Passats, Golfs, Octavias, you get the idea

), the rear may end up being a little costly.
