Thats exactly the problem to be honest, clio's are good value for money how they come out the box, after owning 3 clio's now including the turbo I bought off you I'd rather go elsewhere now, next project being a zlet corsa. The money you spend getting such small gains just isn't worth it.
Zlet corsa is a nice road car and ok for occasional trackdays etc too. Hope it goes well sorting one mate.
