I'm on a quest to complete the game with only stock cars. (And preferably with stock prize cars)
So far I've been able to complete all seasonal time trials with 99,9% stock cars..
No oil change , no other aids than abs 1 and I've lowered the front brake bias on a few cars.
(not for seasonal events , but career races and left them like it)
For the 86 GT Time Trial I used the 15th Anniv. 86 GT.
Diablo GT2 I bought from dealership , because I haven't won one yet.
At Lancer Evo / Chamonix I used TCS 1 & bought Snow tyres.
My times at all the seasonal TT's so far:
(Most of them are hit'n run - get gold and you're done)

And , @
Haarnaald , you may have missed the part about no SRF in 1st post.
I have taken a look at your replays and you don't use brakes in places one must use brakes with the stock cars.
