Vintage Sport Compact tuning: Seeking advice!

Hi guys. I’m loving this division, and want to try and take things further. Does anyone have any hints & tips on how to tune this class of car?

Cheers, and happy racing.

Presumably for homoligation racing? What car(s) will you mainly use?

And are you having an particular issues? Understeer, oversteer, unpredictability? Or are you just looking for quicker lap times?
