Touring car springs

[arransmith27]

I am currently experimenting with the setup of my TC5, and am looking to fine tune my current suspension setup.

I always stick to the same make/brand of springs on front and rear.

Was wondering if it was advisable to mix and match different manufacturers springs front and rear, or if this wouldn't be recommended?

Does anyone have any experience of using springs from different manufacturers between the front and rear of their touring cars?
