If 900 is the goal, it will be an expensive weight-loss program
For those of us who do not have the budget for a ex 155STW, ex 155DTM or an ex 156WTCC car, and use a streetcar as basis, for track days the 156 is clearly the best car over the 145,146,155,GTV. From a technical standpoint that is. Why ? The 156 is the lesser over-steered car, the others will oversteer to much in the end, beyond control. The suspension system at the back + the 'out of factory' wider track are some of the main reasons for this. Unless you only drive on a Mickey-Mouse track, where the GTV might do some good, on any normal track, like SPA or the Nurburgring for example, the 156 is king.
Engine is an important choice. The 8v (as in the pre-156 era), is very relaible, but: very expensive to get over 200bhp, where also the reliability suffers. This means that if you want decent power, the 8v is not to be your recommendation. The 16v, though sensitive for it's belt (change/replace often (including the rollers (metal ones, not the plastic !)), is for serious track days a very nice engine. Yes the V6 has more power (the 24v, the 2.5 12v is certainly not a track-day engine in my opinion), but the turn in on corners is too much less (need earlier braking, and suffer more understeer. Perfect time to pass a V6 with your 16v
. Due to the weight, the 4 cylinder has very nice turn in + extremely late braking. Also it can be tuned to over 300bhp, but that requires some budget... Around 200 bhp is from a money/power ratio a somewhat more 'doable' scenario
200bhp + LSD + shaved down body is quite a nice combo
PS: above is my experience, you need not agree. I have owned all engine types (8v, 12v, 16v and 24v (incl 3.0 24v in my ex-156) and all have seen track days. All car types have been under my butt, most of them as my own car...
BUT: technically best is not the same as to where your heart is. For the same reason I drive a 155 not a 156
Why ? Owning a 155, makes me feel like driving the DTM 1993 once again
Till the moment this b*st*rd
Ecclestone came along and killed the DTM/ITC, the DTM was by far my favourite competition. Watched several races. Still love it (all races where Alfa participated on DVD though
)... This means that: yes I am totally insane: the DTM is far gone from waht is was, and No
the street 155 is not even remotely close to the DTM 155, but then again: Alfa's are about passion not about mind (as otherwise I'd be driving BMW
