Hello Frasie! we are aware of that. Before V6 tire´s, the V5 where more close to real thing than they are now atleast on Vintage tyre´s - Alfa Romeo GTA became 5s slower on most tracks after V6 tyres so we had to put similar tyre behavior to make them competitive. This is a Laptime competition on modena and you can see the difference between cars, they can do almost same time:

I ll paste here the reply we gove in forum:
Hey guys! all this hotlap things is amazing, tnx so much for propose this
@Seria17hri11er
About balance i have to agree with Andy that 100% grip is what we used to balance with GTA but well, cars will never do same time in all tracks.
In our experience and thousands of hours of testing and balancing (7 drivers making many many laps in different tracks) the cars are pretty competitive, but there is a "gap" that its up to the track.
IE:
There was a 0.2s to 0.3s difference in:
Magione (Fulvia is faster)
Imola
Brands Hatch GP
Then you have half second difference in:
Nurburgring GP
Silverstone
And the Fulvia enemy with 0.8s of difference
Zanvoort
(Matias can give the laptime´s he has save them)
After all testing was pretty clear for us that Fulvia doesent like hairpins.
Thats good since all cars have their own strong points, its very hard to lose and crash the Fulvia, but in GTA if you go wide on exit and rear wheel touch the crub there´s a big chance to crash very hard... if you lose the Fulvia u just have to floor the gas and get it into the track again.
The fuel compsution has been taken in consideration also, u can play with it and have a slight advantage in weight. (we are based on 1.6 vs 1.7L engine)
We dont belive they are going to make exactly same laptime but they for sure ll have an small gap that ll allow racers to chase eachother hard and have alot of fun. I ll try to have a video of a race in Tor Poznan against @Jos_theboss wich shows some great action.
And for those who want to beat the Alfa Romeo or get very very close... yes... is alot harder go fast with Fulvia, you have to really be pacient at pushing the throttle, is a weird feeling, you think u are going to go very slow if u dont push the car, but after some time u realize you are alot slower pushing it before its the right time. Also the track line that Fulvia like´s the most is a late apex to be able to accelerate in one shot, have a good view of the exit and go full throttle.
Said this before but tell it again, we dont think it has al the grip it should in the front honestly, but its not far either and if we change that car would be alot faster than GTA wich was not the real thing, GTA allways been bit faster, just Fulvia use to win because was easy to drive, thats the key of her success. (If u ask me, the GTA grip is also bit to low also in current patch).
--------------
So shortly, we would preffer to have V5 tyre´s on vintage cars, but we had to move to V6 with a high prize, we ll do an S1 version as soon as AC 1.5 release and ll have the tyre´s it should (and ofc ll be alot faster than GTA), but as far GTA has the grip it does, we ll still leave 1.6HF std version as it is to be able to run championships!
Hope you understand.
