They make sensa tracks for the mk3? I have them on my Honda Passport and they work alright, but they don't seem like something that would be very good for a performance application. I would say best springs combined with them would be stock.
But if you're going to buy new springs and shocks, then you have a lot more options. And it depends on what you want to do with the car and how much you want to spend.
So depending on those answers, I would be able to make some suggestions.
