TA's/standard. Path to that extra inch!

Hello

Its a mk2f bready, when i got the car it had a set of TA shocks and springs fitted. They are the open spigot type when you move it up the shock to adjust ride hight. I now have bought some new wheels and i need to lift the rear by at least an inch. I believe i read somewhere that TA's bring it down 35mm just by swapping to them? Could it just be as simple as changing back to std springs to get that little higher for clearance?

thanks Nic
