Why not stop compromising the useability of the Clio, keep it for day-to-day use, flog the Corolla and save up for something more focused for track use, like a Clio Cup, Caterham, Elise, etc?
Or, get a Clio Cup and swap the engine with your car to capitalise on track. The one you are likely to get bored with first is the road car, so blow the cash on the track car instead...
